Tuned the Gen 3 platform before. Now tuning a gen 4 E38 with a boost cam and custom single turbo. Where is the after start enrichment tables? Is it "open loop gains?" My AFR is 8-9 for the first 5 seconds which is to rich after starting then leans out to the AFR I want it at. I need to lean it out.
There's an EQ ratio table under Engine-Fuel-Power Enrichment. Check that out and see if that's what you're looking for
There is a command and an Intake Valve temp correction, Set the open loop table to your desired mixture when cold and then adjust the ITV gain to achieve that mixture.Originally Posted by greenjeens

You need to make sure startup airflow, injection timing, injector tip temp and most importantly VE and/or MAF if being used, are right first.

Excellent thank you. I will give all the tables a try to see if I can get it leaned out.
