The Predator can be used to import and export tunes still so if you wanted to get a custom tune from one of your dealers, you can put it into the Predator.

Restoring the original backup to the vehicle will reset the tool so that it can be used an another vehicle. Thanks, if I buy a full version of ...

Mine(U7198) has it under Performance tune, Modify Perfromance Tune...and then I think it's O2 disable???

Since my Predator (U7198 - GM02 2.12 Ver 6.01) has no logging and limited tuning paramaters I'm thinking about selling it. I've gone from mild tuning needs to a bigger (232/234 .600"/.600" 112lsa) cam and stage II 60cc heads so I really need a more flexable logging and tuning platform.

My maunal ...

-8% on the injector slope was too far. I went to -4% and it looks right on. I'm maintaining 0 to +2.34 now. Probably the vacuum leak that was throwing things off.

With Jesse's tune it now runs consistant at +6-8 on the LTFTs. He said not to worry about it and that these are good numbers to work ...

Well I've been running Jesse's tuned PCM all day and with the throttlebody bolted up to the manifold id runs great. Now I can focus on the fine details.

I'm idling at ~970 when standing still. Once the car is rolling it will idle (if I take it out of gear and let it settle) 1180. It will stay at ...

Thanks

Yep, I think he's go tme on the right track!

Email me your extra tune from the Predator and I'll have the P0300 turned off.

Thanks Thanks, I'm running my mail order PCM now from Wait4me...now that I fixed my vacuum leak!

I'll probably email you the tune anyway though so I have a back up tune that will run the engine without SES codes. Just ...

Vacuum leak. Doh!!!!!!
Seems to be running great now.

Just did another hour of reading...it could be a tuning issue, but I can't do anything about it with just a Predator. Maybe Jesse at Wait4me can help me figure it out? If not, I think I'll buy some tuning software and learn how to fix it myself.

That wasn't it. The throttle body wasn't torqued down, but those O-rings do seal well. It runs like crap still with the IAC plugged in. It starts fine, but driving is miserable as it hangs at 2k between shifts and when cruising it just does whatever it wants. I was going down the highway at 50mph ...

Hey I had a similar problem with my corvette and it turned out to be a faulty TPS sensor. Intermittent high idle...1.5-2k rpm. Installed new one and fixed the problem. Its a reasonably priced item so might be worth a try. Just my 2 cents worth. Good Luck.
I'll keep that in mind. My scanner showed ...

With my older 02 LS1 predator I'm limited on IAC tuning. My engine wants to occasionally idle up to 2-3k or when your driving through town it's like the cruise control is always on.

I unplugged the IAC and it drives much better. It just doesn't idle as well. It doesn't want to smooth out and ...

if you're runnin' a cam like that, you really need to get a custom dyno tune in order to get it all setup correctly...
I agree...I'm just having a hard time finding anyone around here. That's why I'm working with Jesse at Wait4me, but it's a long distance tuning relationship so these gremlins are ...

-8% on the injector slope was too far. I went to -4% and it looks right on. I'm maintaining 0 to +2.34 now.

I had postive 8.25 on both banks. I subtracted 8% from my injector slope and 8% from my fuel setting. I thoughts that the way the instructions read...am I going the right direction or am I leaning it out even more?
