Unichip map downloads and tuning

[funbeatsfast]

Really? The Kool Aid must taste great here. He showed Fit and FJ vids, then said that it had nothing to do with the FR-S/BRZ. Great, thanks for the commercial.
I ask if UniChip can raise the rev limit on an FR-S. The answer was - "That's silly, why would you?"
Stop by your region's next autocross event (Really, you'll have a great time). If you're lucky and live down south, it should be soon. Most of the 40-60 second course will be spent in second gear, first just through the first corner or two. Some of it will be bouncing off the rev limiter at 60ish MPH. A shift to third takes half a second, and another half a second to shift back to second. Most just keep it in second gear. An extra 400+ RPM can make a huge difference in times. Changing ignition timing and injector duty cycle isn't the only way to go fast.
The question is still being addressed in a condescending and less than transparent way. I've worked in sales for a long time and would never be this vague concerning my product.
UniChip's pricing is realistically half of what EcuTek is charging (Cable, license, tune) so it's a great deal for a lot of you. Just not for me. Troll? Yeah, I'll wear that hat.

Dude. Simmer down. He's showing us that yes in fact, unichip systems can raise the rev limiter, and on Toyota vehicles no less! It's no less applicable than the Mini example YOU brought up.

This car just came out. Don't begrudge a company for wanting to do just a bit of R&D before they release a capability that has the potential to totally fubar the valvetrain. We all know that for AutoX a bit of extra time in gear is very useful. But just trusting that that extra RPM boost is safe because company X has done it on their car for 5k miles (Which is nothing...) is foolish. A larger company like Unichip is not going to want to risk that liability without some serious research.

Jack answered the question, "Can Unichip raise the rev limiter." He has also made it clear that they haven't decided if they want to pursue providing this functionality for the 86. What more do you want?

Geesh.

Hmm, arent the last few posts what is great about this car? Unichip, ecutek, innovate, vortech, Avo, etc... if this product isnt for you thats fine, choose another one. Its great that we actually have so many choices! Flaming the OEM because the product doesn't fit your needs really doesn't benefit anyone.

Jump to conclusions much? All that from a vague answer? It's not like Unichip screwed over their customers with a bunch of bricked ecus then fled the country like ecutek. I had a bricked 02 wrx ecu.

Truly, you have my sympathies. I have walked in your shoes. That's part of the reason why I'm so critical of vague answers and half truths.

Thanks for taking the time to respond, Jack.

I was under the impression that ECU overclocking was a less-than-desirable tuning solution. Scale the maps, clocks, and hence the rev limit. A few tweaks to fine-tune and you're good to go. Timing issues, relative response time, and hardware reliability can suffer if you don't R&D the heck out of it.

Hypothetically, if the FR-S were to have it's rev limit increased, would the tables need to be scaled?

When I worked for a certain oval-shaped manufacturer, some parts of their strategy were structured to support up to 10+ cylinders and 10+ krpm... even if those values weren't used or developed. Since it's a similar Bosch system, I was curious if it's a "simple" process of overwriting values, or the "complex" methods of scaling either natively or artificially (as mentioned above).

And in case it's not clear... the FR-S/BRZ community really does appreciate aftermarket tuner support. Software engineers and DAGs often put in ridiculous hours (and eye strain) to deliver a quality product. Often without enough so

It rather appears that his vague answers and half truths are erring on the side of caution and are with the intent of NOT making promises on delivery of a product they cant gaurantee. Would you rather they just put a product out there for consumers to utilize and then have to repeatedly provide tech support to correct issues they may run into to the point of potentially causing severe engine damage? He has made no promises that they will put it out (i know as i tried to get him to do it on my car during the initial r&d process, in fact Aaron could tell you that i specefically said that it would be a major selling point) until they are confident it works the way they intend, so why so much hate towards them?

Guys, is there a high altitude optimized tune? I live at 5,750 feet!

[Unichip Jack]

Guys… there’s no attempt to be vague… there simply isn’t an answer yet. We recognize there are reasons to do it… I track a M3 and spend my fair share of time on its limiter (even with a raised redline), but there are also reasons for not doing it. Our goal is and will always be getting things out of development and into your hands as soon as they’re ready and proven.

Shankenstein… yes, overclocking has its issues, but it is an option in our tool kit and is inexpensive. Unfortunately it leaves a footprint, involves soldering inside the ECU where mistakes can be costly, and may or may not be viable “at home.” It works, but it’s not a direction we’re currently pursuing. Remember that we don't write anything to the OE ECU; we look at how the OE ECU implements the limiter and manipulate that functionality… “extending” a map above what the OE computer is programmed for via the Unichip rather than rescaling or overwriting anything. The goal is to remain PnP unless it becomes too costly or complex to do so.

GavinAnt… the maps compensate for the altitude, but we have a sister shop in JHB and they’ve done a couple of cars already. Give Heinrich at SAC Kyalami a call and he’ll you hook up.

All… thanks.

Cheers

*slaps forehead* piggyback! That's an important detail I somehow missed. Totally different ballgame then.

To help people understand:
Redline (and fuel cut) is an event that's usually attributed to pulse frequency on either the crankshaft or camshaft trigger wheels. Usually, the number of clock ticks between TRIGGER_UP events (or missed teeth) will be used to estimate engine speed. The estimate is heavily filtered before the ECU uses it.

The factory sets a threshold value for engine speed and performs an event such as fuel cut (injector return wire isn't grounded), spark grounding, etc to limit additional power.

Many piggyback systems monitor the injector signal for the voltage rise/fall associated with start of injection. They calculate the new pulsewidth and lengthen the ECU's command. It's an event-based trigger method that compares current voltage to a threshold (with some complicated calculations in there).

If there's fuel cut, there's no trigger... and no trigger means, no fuel (ECU or piggyback values). There are some ways around it, such as tricking the ECU to continue fueling, or generating your own waveform. Most solutions are pretty hairy, and new cars come with alot of supplemental systems that have nanny-control (such as the FR-S automatic's "stupidproof" manual mode). Not simple, and not guaranteed effective.

@unichipjack

Hey jack,

Today opening my door the wires leading from the unichip to the flux 2 popped out. While trying to reconnect them all 3 popped out.

I'm fairly certain I put them all in the right spot, but will it communicate with the unichip at all if they are not placed in the right spot and second how much will a new connector and pins cost me? This isn't your guys fault I just obviously did not put enough slack on the wires.

So if I understand this correctly, the only thing I need to do when the car goes to the dealer, is just disconnect the whole unit?

[Unichip Jack]

Important safety tip… for everybody using the Flux2 Display, ensure there’s sufficient slack in the cables between the dash and the display. Too little slack excessively strains the wires when you open the door and can break the wires or plugs.
Husker741… correct. If your dealer doesn’t dig modifications, remove the parts and there’s no footprint they’ve been there. If the dealer is ok with modifications (some of our biggest customers are dealers), leave the kit in place as it doesn’t interfere with anything they want to do when servicing the car and whatever they’re doing doesn’t affect the Unichip.

MapsQ folder update… the 92 Octane and 89 Octane maps are updated. Don’t blow a gasket when you open the folders and see more folders. Details to follow.

Cheers
