Clearly it's wrong. Stock injector size is roughly 300cc, and your new injectors are more than twice that size. You could have split your krkte in half and it would have gotten you closer then what you are now. Krkte will end up being in the 0.049 range most likely. Easy way to calculate new injectors (original krkte x original kvb) / new kvb = new krkte starting point

Short term is not +25%.
I see your file is called "ethanol.ecu".
If you're running ethanol and you "forgot" to mention this little tidbit then LOL...

Your KRKTE is wrong, must be lower.

it says +25 so too lean with 0.070. test with 0.0789 better, yes normal you enriched .frp 3bar yes about 630cc at 4bar rather 710. and ltft are how much? your krkte must be between these 2 values around 0.075 try to let it adapt (or maybe you removed the ltft to adjust to stft?) to give you an idea me on injectors (117) at 4bar or close to 600cc e85 my krkte is 0.072.

I took the TVUB from this post but, I don't know if it's the right TVUB. http://nefariousmotorsports.com/forum/index.php?topic=19978.0I think it's fine, the car runs normally except for a slight lag at low load. Right now I'm at 0.74 KRKTE and the lambda is still above 0.8V at high load. Narrow band  |

The value of TVUB is not universal 3b in bin? You know, how to transform TVUB 3.8bar into 3.0bar?  |
