Make sure you have someone working the camera for us 2moro..... hope it does not go boom.

He wasn't 100% long enough to tell if it was just him wiggling his foot, or if the computer was making changes and it was catching up. Two of the pulls afr at 100% was 11.6-11.7. That's pretty good. Other pull was 100%-91%-81%-97% and the afr went from 12.8-11.7-12.6.-12.2-12.7.

No tuning, just data logging 3 pulls so moe has something clean to work with. Car has a 3.42 rear, so 3rd is like 80-150, don't wanna do that on the street

What's your wot timing set at?

***popo8*** · 12-28-2014, 12:09 AM

Only because im not cofident with any aspects of tuning... i say skip 2moro... make an appt with marcello and make it right the first time instead of risking it.... thats my opiniom

dyno runs. basically just settling afr and timing out. made 436whp and 501lbft of torque before it pushed thru the converter. needs better converter, forged bottom end, and trans upgrade. its still holding together for now though

Congrats man. That was one QUICK pull.

Thank you. I did the math and it comes out to like 24% slippage at 5400-6400 rpm. I don't like how the dynocom dyno loads the car, and it also doesn't have a spark input to monitor torque. So the numbers are just that, skewed numbers. Torque probably from the multiplication of the converter, and hp from the slip.

Afr dialed in for now. So all in all it was worth it. It will still go to jd's at some point, but he has to get the rest of the whipple stuff from @firebird_1995. Also, I have to thank Chris and @sweet_94z28 with tuning help late into the night trying to richen this thing up so we didn't hurt it.

That was a pretty quick pull. Sounded good and numbers will surely improve once the tune is spot on and you aren't pushing through the converter.

The first two pulls were only 60% throttle, his knee was locking up and couldn't feel his foot. I did the last one, afr rich but I'd rather it be sooty than white
