I just wish i knew what the ecu was tuned for... the AFR´s are spot on right now, it took some time tough...

The stock gtir ecus have agressive timing off boost right? but on boost?

Also do you guys recomend any kind of standalone knock detection device?


Turbo ecu's run more timing usually because the compression is lower. duno how well this will show up but I'll post a pic of a turbo timing map and N/A timing map


This one should be a higher comp map since it's from a Autech motor.

MAHA dynos works like that. They have that big losses, but its far from equal to typical "US" dyno whp numbers. You have to do a little math to compare to "US" dyno numbers.

We used this dyno many times, so dont bother about whp.

Do you know how to convert? i know 310nm are 228.64lb.ft

But i really have trouble in the wheel power and engine power, corrected power allready got to conclusion is down to dyno operator input...

Also the drag power is taken after the pull, on deceleration, and it´s not that accurate...
