Full throttle Electric Supercharger Build Thread

[Target70]

new performance assessment:
This car needs better brakes.

I don't see the point of the alt charger. I got on an interstate on ramp in 2nd gear, ran it flat out to somewhere in 6th, before someone jumped in front of me. The volt meter read 27.5 or something like that, or it did by the time I slowed the car down enough to look at the meter, and within 10 seconds it was already back to 28.5. This thing is gonna get me in trouble

Boost log worked this time. 4.21psi at 3400rpm 1.45psi at 7200rpm IAT's ~73F

I have the same setup with the borla uel and trd catback and I find it too loud for my taste. It sounds really nice when I'm reving and or shifting through the gears. But I drive 30 minutes to and from work everyday, and the noise above 3k rpm is starting to annoy me. I just drove 6 hours down to nyc yesterday and I missed it when it was stock volume, even though it was still loud back then (mostly road noise). Check the sound clips on my bulls thread, but I feel like it's louder now).

What did you do to fix the boost tool? Mine is reading -8.6 psi, and then I'm getting -1.8 psi at peak boost, I am really hoping its 8 off but that is probably not the case. That would be 6.8 psi... a man can dream.

@DAEMANO I tried getting some video of my setup but my phone doesnt pick the sound up too well so you might have better luck listening to the other guys clip.

One a side note I found a place selling e85 at 2.55 a gallon only 14 miles away, so picked up 20 gallons!

A few weeks back I mentioned that I noticed my car was running lean in boost all the time, ~14.0. With @Td-d's help, we figured out what was causing my particular issue and now my AFR is right where it's supposed to be. This may be kind of a specific situation but hopefully it'll help some of you.

My car is an automatic with an original cal ID of A01D. That means on the v2.X OFT tunes, I'm running the A01D 91 octane tune which is really B01D in disguise. There are a few tables that I had to modify that weren't available with the definition files provided from OpenFlash. The crux of the issue is that there are a couple maximum load limit tables that aren't defined that effectively pin the maximum load the ECU can use for calculations to 1.3 g/rev. Seeing as under boost we typically see ~1.5 g/rev, this is Not a Good Thing. Additionally, there's an overriding CL to OL delay timer table that isn't available as well, and modifying this one eliminated the characteristic lean spike most people see when the ESC kicks on. Please note that if your car is a manual, or not USDM, the following additions are not going to work because the tables are stored at different addresses between the different rom series. This is specific to the D-series (Automatic) USDM OFT roms, which are based on ZA1JB01D.

So here's the specifics (table names are from RomRaider):

To speed up the transition from closed to open loop as quickly as possible, there are two defined tables and one undefined. These will appear under the "Fueling - CL/OL Transition" group.

CL Delay Throttle A Counter Threshold
CL Delay Engine Speed B Counter Threshold
CL to OL Delay

What I did with these was to set all of the cells to zero. What this does is it effectively removes any sort of delay the ECU might impose before it begins the transition from closed to open loop. However, the main overriding table, CL to OL Delay, isn't defined in the OpenFlash definition file. You have to modify your definition XML by adding the following to make it appear in RomRaider:

In the top section, where the rest of the "storageaddress" lines are, paste this in:

<table name="CL to OL Delay " storageaddress="10DC1E" />

Then, under the 32bitbase section, paste the corresponding table data:

<table type="2D" name="CL to OL Delay " category="Fueling - CL/OL Transition" storagetype="uint16" endian="big" sizey="2" userlevel="3">
<scaling units="counter threshold" expression="x" to_byte="x" format="#" fineincrement="1" coarseincrement="100" />
<table type="Static Y Axis" name="Delay Value" sizey="2">
<data>A</data>
<data>B</data>
</table>
<description>This delay value is used for all SI-DRIVE modes if the 'CL to OL Delay/Switch SI-DRIVE Intelligent' value is zero, otherwise, in SI-DRIVE intelligent mode ONLY, the latter delay is used. The delay value is the period over which the 'CL to OL with Delay' throttle or base pulse width thresholds must be continuously exceeded before the closed loop to open loop fueling transition can take place. Only one of the values is used at any given time to determine the delay. If the current delay is non-zero, the 'CL to OL Transition with Delay (Throttle)' or 'CL to OL Transition with Delay (Base Pulse Width)' tables will be used to determine the transition from closed loop to open loop if either threshold is continuously exceeded over the current delay period. If the delay is zero, then these tables will not be used and the closed loop to open loop transition will be decided by the current enrichment as determined by the 'Primary Open Loop Fueling' and 'Minimum Active Primary Open Loop Enrichment' tables.</description>
</table>

I like to keep things organized so I pasted this stuff in with the rest of the CL/OL Transition tables.

So with the CL/OL transition stuff covered, the load limit tables are next. These should appear under "Mass Airflow / Engine Load". There's one table already defined, Engine Load Limit (Maximum), and its one cell should have already been increased by the OpenFlash guys to 4.0 g/rev. If it's not, set it to 4. Next is making the other two tables available: Engine Load Limit B Maximum (RPM) and Engine Load Limit C Maximum (RPM)

Paste the following in the top section:

<table name="Engine Load Limit B Maximum (RPM)" storageaddress="1044C4" >
<table type="Y Axis" storageaddress="1044A0" />
</table>
<table name="Engine Load Limit C (Maximum) (RPM)" storageaddress="1044FC" >
<table type="Y Axis" storageaddress="1044D8" />
</table>

And then this in 32bitbase:

<table type="2D" name="Engine Load Limit B Maximum (RPM)" category="Mass Airflow / Engine Load" storagetype="uint16" endian="big" sizey="9" userlevel="4">
<scaling units="Engine Load (g/rev)" expression="x*.00006103516" to_byte="x/.00006103516" format="0.00" fineincrement=".01" coarseincrement=".1" />
<table type="Y Axis" name="Engine Speed" storagetype="float" endian="little" logparam="P8">
<scaling units="RPM" expression="x" to_byte="x" format="#" fineincrement="50" coarseincrement="100" />
</table>
<description>This is the maximum allowable engine load. Engine load will be capped at this limit regardless of actual engine load. "Engine Load Limit A (Maximum)" must also be changed as it also impacts the max engine load.</description>
</table>
<table type="2D" name="Engine Load Limit C (Maximum) (RPM)" category="Mass Airflow / Engine Load" storagetype="uint16" endian="big" sizey="9" userlevel="4">
<scaling units="Engine Load (g/rev)" expression="x*.00006103516" to_byte="x/.00006103516" format="0.00" fineincrement=".01" coarseincrement=".1" />
<table type="Y Axis" name="Engine Speed" storagetype="float" endian="little" logparam="P8">
<scaling units="RPM" expression="x" to_byte="x" format="#" fineincrement="50" coarseincrement="100" />
</table>
<description>This is the maximum allowable engine load. Engine load will be capped at this limit regardless of actual engine load. "Engine Load Limit A (Maximum)" must also be changed as it also impacts the max engine load.</description>
</table>

You should end up with two new tables with engine load versus RPM, going up to 3200 RPM. What I did here was change all of the cells from 2000 RPM up to 4.0 g/rev, to match the overall maximum load limit.

After these changes, my AFR doesn't spike on activation, and stays on target through boost. Hope you find this useful! And thanks again to @Td-d for providing me with the definitions for these tables! If you ask nicely, maybe he'll provide the storage addresses for other roms as well!

I was using OFT to log. After the recent update we can now log 12 channels instead of 10, but Shiv said something about the last 2 channels glitch and read 0, which is what my boost was doing. I just removed 2 other channels than saved and added them back, so that Boost was not one of the last 2 channels.

Have you updated your OFT completely? I remember a long time ago there being a problem where boost wasn't reading right because barometric pressure wasn't factored in or something like that. I'm not an expert, but it might be worth looking into. My negative went all the way to -12, and up to +4, so even your vacuum/boost range looks off to me.

Pleasure, mate - I've got them defined for all the roms (in fact the load tables are all up on my Github respository) - I'll just need to add the CL_to_OL_Delay tables. @Shiv@Openflash will need to update the definitions hosted on the OFT website.

[Target70]

That would be great if shiv could take your method and release an updated ESC tune for those of us who honestly don't understand half of what PantsDants just said.. or just don't feel comfortable trying it themselves.

I told myself I wouldnt post the following comments about this product but as a prior owner i feel i would be doing the community some help with this brief review written from my phone and a few beers.

I had the product for over a mos and it put a huge smile on my face initially. Yes the car is absolutely faster than without. Anyone who is skeptical about the dyno or refuses to believe it works give it a rest. It works exactly how it claims to work. Boost when you engage and lots of tq at low rpms. Which is very much like the 2015 WRX with respect to tq and the share the same engine.
Anywho, while my primary reason for selling the product was to free up cash i wanted my old car back. That snappy high reving engine that begs you play in that high rpms range. Not this new car demanding of you to mash the throttle 100% at low rpms to get power.

Now that this has been off for many weeks i cAn tell you I fell in love with my car all over again and let me tell you the reasons why.

1st i believe that everything Shiv touches turns to gold and so I cant attribute the mucky throttle response to his tune therefore, i believe that mucky throttle response can be contributed to the restriction of the compressor. Its not that car really felt slower when not in boost ( which when you think about it is 95% of your driving time) but it lost some of its lively snappy behavior and that ladies and genitals is unacceptable. This was one of my biggest issues with the system.

2nd 100% throttle. How many of you find yourself putting to the pedal straight to the floor in your driving experiences? Prior to this product I could see myself doing that only when i was racing a dude or running a data log. Even then I felt like a monster beating on my car. It just felt so unnatural and brutal. Did i get used to it after some time with this product? A little but every time i engaged the boost it became this "holy shit experience" in which everything became intense. Yes you can adjust the switch to i think as low as. 70% throttle but when i am reving the engine at high rpms, the way it is meant to be driven, and i have to be cautious not to accidently engage the boost i feel like i am driving with a handicap. Not to mention you lose power at high rpms due to the restriction. This leads me to my biggest issue.

3rd no partial boost. I did know what to expect before i got this. I did know that this thing is literally engaged by a switch. Exactly like a light switch. But reality kicks in if this is your DD. I hardly ever used it and when I did it was almost this planned approach which ruins some of the fun in this car. Lets face it, with only 200hp this car is All about fun. Think about it now.... How many times could you see yourself mashing the throttle like a tyrant on your way home and from work? I hardly used it.

4th that much LOW end tq feels unnatural and unsafe to the car. Do other systems produce more tq or course but at that low an rpm? When boosting from 1st to 2nd i would feel a violent jerkin sensation. Granted i was really on it but still. Makes me wonder the long term longevity of my transmission and everything else that follows with this rig.

I am ready for the comments and I know their is a huge fan base for this product. Tbh their should be. For its cost an ease of use their should be. I just dont think its for everybody at least not for me.

Please note that the list is not in order so the only important thing is that you are on the list.

@Robftss has 5 kits that are ready to go, people will be getting PM's for those this week. If a response is not received he will move down the list.

Thanks all!

@BadHabit

Thanks! Looking forward to the kit.

Thanks for the honest review from your point of view. I dont see anything wrong with this at all. Everyone is different and not every product is going to be perfect for everyone.

I actually just recently have had the same experience as you, i have went back to stock....not because i wanted to but because Rob is working on my controller so i have been without boost since the dyno day. All i can say is i feel like i am handicapped driving around. The car just does NOT move(even in stage2 93 oct that i am using now). The car revs and revs and revs but it doesn't really feel like you are covering any ground. The culprit here is the FLAT torque curve and general lack of torque to begin with. I found myself always having to downshift just to make a pass up a hill. I feel that i have to rev the crap out of it all the time just to keep up with traffic, which i dont really like doing because my car is quite loud with the exhaust.

Anyways, different strokes for different folks. This products intention is to dramatically change the acceleration characteristic of this car for a fairly low $$$ investment.


For reference here is my stage2 dyno(OFT, OFH, trackpipe, 94oct), it is just soooo boring....there is something to be said about a flat torque curve yes....but a flat torque curve that never actually makes decent torque is also not that fun to drive unless you can rev to 9000 rpm....just my opinion obviously.

I mean it only ever makes 142tq

yes, you do have to down shift, rev match and rev the crap out of this car in stock form to get that rush and speed and THIS is exactly what sold me on the gt86 when I first got it!

I mean it only ever makes 142tq yup at 6600 rpms! its a screamer for sure With the esc that ridiculous tq in such a light weight car comes in at like 2k. Amazing but much much different from how the car is supposed to drive.

different strokes for different people for sure.

[GTO5005]

Perhaps somewhere down the line I might miss the benefits of staying "pure", but right now....



Well as fast as my 2675$(ESC,Headers,OFT) is going to take me.

[Namuna]

Ok, so after reading Boofneenee's comment about the boost being binary (it's either all the way on, or all the way off, no steps between), and it's been in the back of my mind...But I'm wondering --and forgive me if it's been discussed and dismissed ---, but couldn't there be some kind of potentiometer (or whatever appropriate equivalent) used so it's a gradual ramp up to full boost?

I'm in the same camp about not really stomping the gas pedal to the floor except on that rare occasion...So the notion of having to get used to doing that with this ESC seems a bit unnerving.

Here's a crazy DIY idea for a different place to put the boost-on switch... Instead of under the gas pedal, bust open the RPM gauge and attach one lead to the needle tip and the other lead as a strip that starts from say 3,500rpm and all the way up. Then under acceleration, once the rpm needle hits 3,500rpm and up, the circuit is closed and boost is on!

[DAEMANO]

My experience is this

Without Phantom ESC. WOT = Lots of noise but little motion. Car had much more chassis than power. Really have to hustle the car to make it quick. This can be rewarding in itself and If that's what some ppl prefer, more power to them.

With Phantom ESC. WOT = Feels like a turbo with about 7-8 lbs of boost and about 50% less lag.


With Phantom ESC + Catless header + e85. WOT = Same as above AND at less than WOT there is good power & torque so the transition from ESC OFF to ON feels more natural. The car still maintains it's excellent balance and chassis, but due to the header & e85 I have more power through a corner (at 20%-70% throttle) but not so much to unbalance the car. Then when I straighten out, I time my WOT so that I have the full effects of the ESC at corner exit. It was all a matter of learning to drive the car with its' new Phantom hardware. This feels brilliant as the car rockets away from a perfectly executed turn. Partial boost isn't really necessary because the car has plenty of power mid-corner if I enter and turn-in correctly. I love it.
