Look at these Parameters, what you think?

Ok, we got the cable and scan software working. HUGE thanks to Bob @ www.aldlcable.com (http://www.aldlcable.com)

We went out for a few runs and here are a few things I noticed. Give me your opinions.

10 deg of spark retard max wot, 4-8-10 as rpm climbed
02 sensor mv = 897-910 max wot
spark advance = 38 deg max wot
AFGS 200max wot

[gregrob]

Another question, is there a conversion for 02 mv > A/F Ratio?

I read you want to be high 800's or right at 900 for a N/A car, so this tune looks good. Just wonderin what A/F that corresponds to.

i run turbo cars in the 850 range, N/A cars usually 780-800. Take the timing back to around 34 * and lean it out a little is what i would do

[gregrob]

Awesome. Have you checked the actual A/F at 780-800? What would that equate to?

I wonder if we leaned it out a little and got it to quit pulling knock if it would run harder.

[Grr]

well you really need to get a wideband, back when i had my GN i tuned it for 780-800 at 30psi on pump and meth, on my GTO i did 810 or so, wound up being 12.9-13.1. On my car i shoot for 13.0 N/A and about 12.2 under boost

Thanks man
