for any n/a setups, especially 305's, but 350's welcome.. Im curious as to how much you had to change your power enrichment numbers to get the desired A:F ratio..
I have 22lb injectors @ 45psi on my 305 and I have dropped my PE numbers significantly I feel just to get it in the low 12's A:F

I appreciate anyones help

 

Hey just wanted to throw this tip your way because its something I did not catch initially when tuning the power enrichment;

Make sure your BLM's are close to, or under, 128 just before they "lock" for PE. If they are above 128 they will probably lock in at a higher value causing a rich condition - so get the VE tables dialed in first.

Another observation I had:
Even after I ensured a 128 BLM every time it hit PE mode, I still found that the %change to AFR in PE was not really accurate (for me). I am running around 13.6 which is ~8% change to AFR. In reality my 2 tables that control PE AFR % change are each at ~2% so you may not see a direct correlation (but again this is just what I experienced).

Hope this helps!

 

Thanks but how am I supposed to tune my upper maf tables to 128? I k ow it's rich because of the larger injectors and more fuel pressure but wow it's a lot
