You want to compare to other cars right? Same dyno is great for one car, but different cars don't often have the luxury of being run on the same dyno. Percentage delta HP IS the improvement from baseline, in percentage rather than raw HP. I said that. Perhaps look up the definition of delta.

im not going to start a pissing match here. +/- maybe 3% at best/worse will be the difference from raw to delta on such a low powered car. thus is it really necessary to compute for a basically negligible difference? say +/- 5hp? no thats seems to be a fairly standard variance.


honestly i'm very impressed @Boosted2.0 with what you guys have come up with, when i get my car (still on order 4months and counting) and have it broken in i'll be in contact. did i here you guys are doing an intake/intake manifold? early in this thread? I'm going with a Resonated SRT header back exhaust (maybe a Nameless catted header). should be interesting to see what your tune produces. Tune will be first though.

Heck we could have also posted the 173 whp dyno plots with the IAM set to 0.7 which is the default setting and shown that as the "before" showing gains of 17-20 whp from just "tune"

Point being using the before then after delta is not always accurate if the before figures are being fudged to sell the product.
awesome of you guys to do this :happy0180:

So we confirmed 2 different BRZs today and both behaved just like our FRS - they picked up 4-6 HP immediately after an ECU reset. We'll get the graphs up in a day or two.

Oh yeah, and we're now site sponsors, and we will be working on a header back exhaust tune next week to go with our stock tune. They should be available in a couple weeks.

Did you log the IAM value before and after? I've talked to a couple other tuners recently and both have said the value, at least on the BRZ, defaults to using .7, not just in the Ecutek supplied base ROM. I'd be very interested in seeing anything different. I do believe the car makes more power after an ECU reset, it's been seen not only by you but others as well. I guess I'd like to see some empirical evidence of why.

The reflash I'm running now, the tuner uses a value of 1.0 when creating the maps but sets the IAM to .8 in the tunes he sends out because he doesn't want someone getting hit with knock right off the bat versus the ECU learning up.

No we didn't - We simply did the dyno pulls to record power levels and behavior after the reset. There is no way that it is a 0.7 dfault however. My car at 0.7 IAM was a solid 7 HP under where it comes in after the reset.

Sorry if I missed this, but can you explain the 177whp run that states it is the "Ecutek base run" ? Are those numbers also tuned? Is that the base flash that came with the software, and then you made adjustments after that ending with the 190whp numbers?

Yes - the 177 is the stock tune, unlocked with the IAM set to 1.0 - it matches what our car has been able to put down consistently after an ECU reset. Before the reset it is usually at 172-174

So i know u guys gain power after an ecu reset on stock software but do u you see any gain in power after an ecu reset after flash? Just a little confused. I always reset my ecu after i flash a new rom because it always feels better IMO

I thought the process of flashing effectively resets the ECU.
Am I missing something?

Awesome to see Boosted2.0 on this BTW. :happy0180:

Well, it would eliminate all doubt in the absence of cold hard facts on that subject.
