My $59 problems/tuning a turbo camaro

**fasteddi** · 03-07-2012

OK mark. Thanks. I have a good grasp on the PE adjustments...i think.

Since I putted on it for 60 miles today, I just had to go play with it a little before work.

Here are some numbers off a tunerpro datalog from a "somewhat" good launch on a flat road up to 100Mph.

Can you guys look at these #'s and tell if its somewhat fast, becasue honestly I've been driving this thing so much that it doesn't feel that fast anymore. Thanks!!

0-80Mph 10.62 Sec.
0-90Mph 12.49 Sec.
0-95Mph 14.25 Sec.
0-100Mph 15.71 Sec.

If I had to make a guess, I would say that your 14.25@95mph looks about right for 1320. In the ballpark at least.

Yea thats what im hoping for. Any 14's will make me happy for days!!! I don't even care if its a 14.99.

Quick question, does the car run richer or leaner when the ambient temp goes up outside. And lets assume the humidity is a tad lower. The car would become richer correct? I think I have a great tune right now for WOT and crusing, although the AFR at wide open throttle is in the lower part of the 11's(11.2-11.7). I feel so confident in the tune that Id go to the track right now and run it WOT the whole way if the track was open. Its not the most agressive tune, but it will get me down the track safely.(10PSI)

air temp SHOULDN'T effect fuel trims. that is partly why the IAT/MAT sensor is present, to account for that.

hotter air is less dense, so if you didn't have enough correction for the IAT/MAT, the car would run richer.

humidity... no idea.

Doubt anyone will believe me since I have no video of it, BUT, i did manage to stay side my side a 5gen V6 camaro today from 40mph up to 80mph. I didnt want a speeding ticket so i stoped the race... but still dont those new LLT 3.6L V6's have like 250-300Hp??
But anyways the car is a blast to drive as it was 70* today and I could just roll the windows down and cruse. Thanks everyone for the help thus far!!!! This car is just so fun to drive when on the hi-way. Its a sleeper till that turbo spools up. Fun Fun Stuff!!

The car ran a litter richer but only could you tell on the excel log. Average 11.8 under boost. (Crusing was 15.2 AFR average without boost) So I racked up 150 miles in the last two days with it being a pretty reliable car in town, crusing, and getting on it. So thats all I can drive it for a bit as the 93 is killing me at the pump when I get gas. Might get 30Mpg on the hi-way, but only like 3Mpg when on boost!! When its 4bucks a gallon...It gets exspensive!!

the 5th gens make ~300HP or more, depending on the model year.

but trust me, you're probably far head on torque.

Sounds like fun and good weather, dam!

What are good AFR supposed to be in boost?

**RobertISaar** · 03-08-2012

assuming a good intercooler, and E0 gasoline, i like ~12:1, maybe a little richer.

He's asking about in general, not with correction.

For the same amount of fuel being passed through an engine between cool air and warm air, the warmer air will usually show a slightly richer condition.
