During the launch control (on both of my speeduino projects ) I get a rich AFR when on the hard limiter.
My response does not answer your question of adjustment, but seeks to verify your purposes in using Launch Control. Keep in-mind it is very difficult to get a realistic AFR/Lambda reading when in Launch or rev-limit, as the sensor is reading both excess air from misfiring cylinders and burning misfired accumulated fuel in exhaust ports, manifold(s) and piping. What method are you using to determine actual AFR during and after Launch?
In most cases (yours may be different); whatever the AFR reading is while engaged can be regarded as effectively irrelevant, with engine torque response on Launch release the primary goal of using Launch, whether using Launch as a form of anti-lag or not. From a results-oriented angle, one check is to engage Launch, then watch the logs (and check 'feel' for signs like rich stutter) for the AFR to stabilize and engine response immediately after releasing Launch
. Again in most
cases; the primary goal here is to verify the engine responds cleanly with best torque on Launch release — whatever that means for AFRs while Launch is engaged. Do you have different goals for using Launch Control?
