My $59 problems/tuning a turbo camaro

[fasteddi]

Ok thanks dave. I though it might be somthing like that. So if say i was tuning a certain boost level , and I wanted 11.7 AFR and i was getting 12.2 on the datalog then i would..... 12.2/11.7= .956 then use that as a multiplier for the VE cell to lean out the condition for that cell.

Yes, that math will work.

Not to cause confusion, 12.2 is a leaner AFR than 11.7. The math above should be 12.2/11.7 = 1.043. So multiplying VE Cell times 1.043 will make the AFR Richer from 12.2 to 11.7.

Don't like the $59 autotune excel sheets?

I haven't used it, since I needed to add a plug in, way back when I tried it, then just got used to tuning manualy.

Get the Ostrich, it will make this tuning go a LOT quicker. ;)

Yea ive burnt a good 15 chips so far today and am still not happy.. mabet 15 more and i will be..

I though the autotune was for TP V4??

Part throttle tuning is ok, idle is good. Heres a video 25 chips later....




Max throttle 90% on one pull, max boost 9.5psi, arfs ok(need to still take a little fuel out in some areas) spark knock is only present in a few cells with less then 1* of retard. I will get rid of that knock although im almost certain that its from a rich condition since that was the issue earlier today.

Enjoy the video and the comentary, I do think I might be able to make a 14 second pass come spring. I can only go so fast on these country roads, its hard to find flat ones....

I really can't comment on the video. I will say, I wish there were sunny skies were I live. I haven't seen the sun in almost a week, I'm jealous!

25 chips, 2 1/2 hours to add fuel... would be 20 minutes work with my AutoProm!

1 degree pulled from timing is nothing. FLOOR IT!

White plugs? That's lean, tan is better, black is rich...

I think your doing great, why sound so discouraged? Plus you have sunshine! I remember sunshine...

This is a weird winter in ohio. Spring will be here soon though.
