I'm currently trying to fix someone's tune here in germany that has/had OTTP stage 2. I'm having problems as it is just pig rich. It just pegs 10.0 afr. Other than that, it is a decent tune, but man it just dumps fuel.

Not a fan of OTTP tunes. I had mine custom tuned, but I watched my tuner trying to retune another Cobalt that had a tune from OTTP, and it was also pig rich. With full exhaust, intake, 2.8, etc, that car only laid down 210 whp. The tuner tried everything he could, but couldn't retune it because OTTP's PCM was locked. After multiple attempts via phone and email, neither the tuner or the customer ever heard back from OTTP. This was well over a month ago. Customer ended up having to drive 2 hours back home and eventually ordered a new PCM from ZZP.
Get a custom tune and be done with it. Mail order tunes are "get me by" tunes.

I hope to god I can't help this guy out over here in Germany. It would really suck if the PCM is locked. Doesn't seem to be so far, I seem to be able to change whatever I want, but I for sure can't get the damn car to lean out. I've even changed all the adder tables to 1.0 just to see if it would read PE only and it won't.

its odd that it is running so rich. i have flashed several cars with ott stage 2 tunes for people that bought them and the cars run great. a tad rich at idle but that is easily fixed. i have actually never had to scale the MAF at WOT with an ott stage 2 tune. it has always been spot on a 11.8 to 11.9AFR

not this car. It's OTTP stage 2, and it doesn't run anywhere close to the commanded AFR during WOT. His cruising and idle AFR is kind of all over the place as well.
It just kills me that flattening out the adder tables still does nothing. I can't get his car to stop flatlining 10.0 afr no matter what I try. I've got Jimbo taking a loot at the tune to see what he thinks. If anyone else wants to try to help, I can email you the tune.

Yea, I took a scan, it pegged 10.0.
I changed the adder tables, it pegged 10.0.
I changed some diagnostics, it pegged 10.0.
I changed the PE multiplier to 1.0, 1.2, 1.5, it pegged 10.0 everytime.
It's crazy, cause he has ZERO knock, and he can run 19degrees flat no problem. Just crazy rich.

I would hope that the fuel trims are dialed in on ottp stage 2.
Blazin, if your tune doesn't work, I'm going to modify the tune I had on my car and try it. Mine was super aggressive, but I can back it down.

Bottom line; it's a canned tune, go figure. Just take a bunch off the MAF table and you should be g2g broski.
