thanks for the answers but why it thinks it is super lean when on 3500rpm it has about 0.828 actual lambda and correcting it and when it hits over 191% it tries to enrich it which actually leaning me out.calculated egts are about 700celcius..i have notice it is always stop lambda correction after 191% calculated load.does this make sense?all the other time i have ok fuel trims and lambda correction..

I use Bosch 630cc and has at most 12ms at 3800rpm which is about 40% I think. I spray methanol after thesevlogs to make real Afr go down for better. The only same issue in my logs is 191.7% load but it must be just a consequence

the problem is that when i hit that load it stops calulating lambda and goes 0.750 and i have seen it  about -14% before it stop taking care of lambda.it is easy to see it in that log. there is 0.828 actual,0.828specifiedlambda 10.23ms,3280rpm,610celcius. 14.1 correction lambda,O2-Reg.ON and after that it goes
0.750actual,0.797specified 11.13ms,3440rpm,615celsius.0.8 correction freeze,O2-Reg.OFF..i hope i had my injector maxed out but isn't these things strange..??

I will try to make a log with me7 logger tomorrow. I will borrow one other laptop.. Please one answer only. I have tuned via kflbts and it is Max 179.30 % (with 0.797afr) . That's where after that I lose my correction. After this it goes to 190%+++.. Are they familiar between them.?
