6.1 and MAF translator

[Doug P]

Just purchased a MAF translator and am running the 6.1 chip. Car is running a little Rich at idle and I was wondering if I should make adjustments through Power logger or through the MAF translator ?

First, how rich is it? What is the AFR? In general, you can't change the idle AFR unless the BLM's are at their limits.

So I only have after install numbers I can find at the moment. I did install a new 02 sensor also with the translator. I put maf base on 2.
Numbers are as follows after its warmed up at idle.
Afr 13.0
Blm and int - 128
O2'S - 850-860

 

[EricM]

An AFR of 13.0 is normal. I program it to idle between 13.0 and 13.5.

 

[Doug P]

Will it be OK to leave base on 2 in translator?

 

[EricM]

Yes, as long as the BLM at idle is ok you can leave it.
