Blue line (OP, post 1).... your boost plot is slightly better.

No, I should be getting it today or tomorrow hopefully. It says the estimated delivery is today but who knows. I plan to test all the batteries when they are out. I just know it feels a lot different then before, there's no push back in the seat feeling. The voltage does drop however and the compressor spools so the controller is fine.

hmmm so do you think it could be a bad dump pack?

I would pull out the batteries today. Test each one individually and make sure they are producing approximately 12.8 volts. Also double check your connections and make sure they are not reversed.

Never mind i suppose. Sorry for jacking the thread guys.

thank you for your time.

I see what you mean. This is a video of a stage 2 FRS (intake and full exhaust from the header back) running Ecutek.

The Black FRS is running the ESC with no tune and no other modifications(stock exhaust).

"Track-usable" is not the same as a purpose-built FI kit. Of course, it can still be used on the track, but has it's limits and is less than ideal.

Battery and cooling mods will add to the cost and complexity of the kit. Conversion tray - $210, aux charger - $300-400, vented hood - $750, etc. That's why a traditional FI kit is still the best route to go for track environments.

I'm not saying that the ESC won't eventually be upgraded to a point that would make it be a great option for track usage. Technology is driven by wants and needs. And it moves at an incredibly fast pace.

But as for now, I'm having a blast with the extra boost in power on the streets. On the tracks, I'm still working on improving myself before performance, and I still have a long way to go.

Thanks for keeping it real. I applaud the efforts of those here who have tracked it and modified their cars to help the system put up with track abuse. This is an excellent option for street cars and it makes great torque numbers which are extremely rewarding for its owners considering their overall investment in time and money.

On most tracks a car will be in the upper rpm range most of the time.

Case in point

The ESC apparently works on track if you cool the controller properly and add extra batteries. It may even last a full 20 minute session with lots of WOT in the hands of an experienced driver. But the fact is that the boost tapers off greatly and for the majority of of the WOT events on track you will be out of the ESC's efficiency range, which is down low where you get the 5psi and the surge of torque. I understand that every PSI counts and the power increase is there even to redline with 1 to 1.5 PSI. Is it worth it, for a pure track application to have that little boost in the upper RPM ranges? The ESC cost totals in a little over 1/2 the total cost of a full-time supercharger which builds boost/power/torque progressively and you're making 7 to 9 PSI to redline. For me when I consider both and assume the ESC has full support for track applications and the controller overheating issues are resolved, I am inclined to keep saving for full-time FI.

I am NOT trying to start another debate between part-time and full-time FI. I just want to lay out the facts of both for pure track usage. For me I have to consider that I will be using any FI kit on track frequently and I would want the performance benefits to be usable in the upper rpm range instead of the lower. The ESC just doesn't make sense for a track application and I'm not sure any modifications to the system could change that. The voltage would need to be much higher, the compressor spin much faster to get more high-rpm boost, the controller heat management demands increase, the battery capacity increases... which would blow the cost out of proportion to where it no longer makes sense. It's making much better sense to me now that this is a street-only option.

That said, I'll continue to help development of the ESC for track applications in any way I can without actually buying one. Please feel free to reference any of the raw track footage linked in the OP of my build thread for rough (audible) WOT data. At Road Atlanta, my home track, I'm WOT quite a lot through a 1:50 hot lap. I'd say around 60 seconds per lap. I don't have any supplemental data but I know that my oil temps stabilize around 230F on track and my coolant temps hover around 200-210F on track as well. The engine bay gets hot for sure.

Connections are fine as they haven't changed since I have had the ESC. I will however test them and update you guys. Thanks

I said that the numbers are comparable if not better then the stage one kit that avo offers., there's really no need to come in here with your chest pumped and all gang buster out bro, I'm merely comparing a stock avo Stage one tune vs an esc stock tune. With that said,for the price difference i will still pick the esc.

Some of us are Aren't looking to make 9,000hp just a good DD that will get me through the day is just fine.

Nah man, no chest pumped, no gang busters, I'm not a "bro", and no need for you to be defensive. If your ESC makes you happy, then that's all that matters. Kumbaya.

Wasnt being defensive, just reiterating what i posted.

Hey rob, seem like others are having a hard time believing my claims of 5.8sec 0 ~60 , so I'll do a few runs tonight and record it with a GoPro to legitimize my claims

With a gtech of course, as to the accuracy of gtech people will have to contact the manufacture if they disagree with the claims of +/- .01

Come on.. it is all about the launch. I can totally see 5.8 if you can get it to hook and run.

I agree, but there are others that don't, I'll do roughly 3 runs from a dig at different rpm also. Maybe it'll help others with their launch. Not that i am a pro, but it might be of some use to others

I learned the hardway this weekend at the Stafford Motor Speedway that controlled wheelspin can pull harder that grip with poor surface conditions.

So yeah, DAEMANO is correct that the esc is comparable to our even better then other stage 1 fi kits. Even vs turbo kits

Edit; all claims are subjective to my own personal perspective, no ill intent to mislead or downplay other kits.

Also,this is just end user dyno vs end user dyno. I'm sure the manufactures dyno would look allot better :p

Haha thanks for dragging me into this one.... But a correction for you, my "stage 1" kit was never dialed in correctly before I upgraded. Something that popped up after that dyno was the fact that my wastegate actuator wasn't functioning correctly. So that dyno is actually only on 3.5psi of boost. That and an overly restrictive exhaust were why the numbers were so low.

All it took was to replace the wastegate actuator and I went to 245hp. With boost control and a half decent tune it then went up to 270hp. Now well beyond that.

But best of luck comparing a turbo to an electric supercharger.
