lambda target issue after start up

[james]

hi all im relatively new to vems,  I have v3 ecu on a bmw m20 turbo and I have noticed on vemstune that some times as soon as I have started the car the lambda & EGO - correction drops right back and flicks from 0.65 to 0.70, I then have to switch of and restart for it to correct it self and work correctly has anyone got any ideas what's happening?

the above may or may not be linked but another problem has started which is starting from cold it cranks for a  10 - 20 seconds before it will gradually fire up, but as soon as its been running it will start  up straight away could this be linked?

thanks
james

Hello James,

Please make a datalog (.vemslog) showing this behavior and make a sharing report so we can review.
