I have chosen to go with open loop tuning. I am trying to get a base to start tuning. Does anyone know what the pcm starts the AFR at approximately? I just want to know where to start.

 

AFR depends on coolant temp and intake vacuum. I can't tell you what AFR it "starts" at since it depends on those 2 values.

Check the "open loop temp vs. load" table, that's what you will be editing. Note that the AFR's listed will only be close if your injector constant is accurate.

 

What are most guys running as a constant for svo 30lb'ers?

Thanx for the response.

I ran an open loop...Make sure you have some sort of resistance..Or it will equal problems

What do you mean resistance? I'm lost here. lol
