I am trying to correct my cars tune and want to understand the tables better. I am new to tuning a PCM
In my 30+ years building old cars the key has been research, reading and looking at known good running combinations.

Anyone offer to share their tune (similar to specs below) please pm me.

I'll just be asking for your specs and give you my email

Or, if you want to look at my tune to evaluate it - let me know.

The issue is it goes very rich at high rpms / under boost.

thanks

Going to be hard to evaluate it without logs and/or wideband readings.

How rich is it going under boost? 11:1-11.5:1 should be fine for a FI motor.

 

I am finding that out. My cable won't read my PCM yet to log, working that out.

I don't have a wideband in the car yet but on a dyno the car was running ~ 14.2:1 up to around 3,000rpm then under a WOT pull A/F ratio dropped from 5100 rpm = 10:1 to 5800rpm = 8.8:1 with ~51psi fuel, 10.9lb boost


I would like to see how other similar builds have their tables set up - just as a learning tool. I read tons of 'how to tune' things, but actually comparing numbers helps me see the picture.

 

You might want to ask on the "Computer...." or "Forced Induction" forums.

joined site, thanks.
back running with new engine, same specs but AFR 195 heads and lowered (8.5:1) compression
I have the .bin and .uni files if someone cares to try and help tune it in
