log on gtir
Hello guys just want to ask regarding on the log i made for gtir. As i know the stock gtir has 7.5k rpm. but when i try to reach the rpm limit it register 7.7k i think it can still give more. but just wondering this something change from my ecu? or does the rpm view on NDS is accurate ? than the rpm display in the tach?


here is the screenshot:

Tacho's are indicative, not accurate, so 7.5 could easily be 7775. The tacho is 4% off which is indicative.

Some other concerning numbers from your log are

Speed - 0 kph - This suggests that you are bounding on the limiter without load, that is stationary, WHY?

Battery - 12.8 at those revs, it should be 13.4 charging so you could have a dodgy alternator.

Duty Cycle - 33.24 - That is rubbish if you are using standard(ish) size injectors, or are you 1000-1200cc injectors on a standard engine

AF Ration - Rich - not with that duty cycle it shouldn't be.

These numbers suggest something going on due to the conflicting info.

jmo correct it if it's wrong.
