Tuning...Tech 2 or LS1 Edit and Dyno?
I've been having problems with my car since I installed my LG LT Headers. We have checked the 02 sensors a million times so don't say "its probley the 02 sensors"! I've heard that a lot. I think it could be a spark plug or wire. My car feels like its missing and my brother in law hooked up a computer that said I have a mis-fire in the 2nd cylinder and it also had some other codes that I can't remember off the top of my head but he didn't know what they were. I'll check with him because he wrote it down.
Well my car probley needs a good tune anyways. So I called 2 different tuners who are vendors on this forum and 1 uses just the tech 2 and the other uses the LS1 Edit and a dyno. So I'm wondering which one would be better in my case? I know the dyno would probley be better but for my codes that are coming up would the tech 2 be better or can the LS1 edit do the same thing?

Normally I would recommend the LS1 edit and dyno tune, unless the one using the Tech 2 is Kellermeyer. Otherwise I would recommend Livernois motorsports or Chris at AP engineering. Regarding the codes, write them down and then do a seach for DIC Codes as there is a listing on the forum of all the codes and an explanation.

I have had some issues with missing (detonation ) found that shell gas makes may car ping like crazy. Also my plugs were gapped at 35 also were NGK-TR55ix . Increase the gap in your plug switch to non iridium plugs. Worth a shot

I should just have him install the AFR 205 Heads.
Yeah, the cost for a full tune about made me sh_t myself. I believe it was $535. It is a hike but thats were I'm going Wednesday.
Here is the code or codes my car read:
1571 TCS PWM CIRCUIT FREQ SIGNAL
By the way Mark what is W2W?

First of all, you cant tune a car with a Tech2. Its a diagnostic scan tool, not a programmer. If someone says they are going to tune your car with a tech 2 they have no clue.

The tech 2 can do limited programming and flashing of the PCM. However, it is limited to the EPA paramaters and the knowledge of the user. They can also reset PCM's and update the PCM. LS1 edit and HPTuners can change over 100 parameters. If you have a stock engine with limited bolt ons the tech 2 will do. Danny Kellermeyer uses it to set up TCC corvettes for SCCA racing. S/C and injected cars, head and cam cars, etc, usually use LS1 or HPT for better tuning.

1. In your other post i also only thought the tech 2 was a diagnostic tool so this confirms my original thought.
2.If your going to do a charger later (soon) i would say to wait and tune it all at once, some tuners will charge you for retunes.
3.I dont think any tuner will tune a car that is not mechanically stable, so you would need to get that code fix and not just try to tune the car with that code being thrown.

I agree. So would I have to go somewhere that has a tech 2 or would APE be able to fix the codes?
Thats what this whole post was about. I might have messed up with the title of this post but that is exactly what I'm trying to figure out. Can I have APE fix the codes and tune it or should I go to Specter Werkes first and have the codes fixed and then go to APE? Or should I go to a dealer? I would think the dealer wouldn't want to work on my car because its not under warranty and I have aftermarket parts on it. I'm more concerned about the codes right now because my car runs like boo boo.

The best use of Tech 2 is in conjunction with LS1edit on the dyno and then the highway. Tech 2 will note misses, knock retard, injector pulse width, IAT, etc so that the correct changes can be edited into the PCM for additional runs to determine if the needed changes took effect and in the desired direction. The Tech 2 tells the tuner where to go with LS1 edit by data gathered on each dyno run. THEN, take Tech 2 in the car on the highway and verify good tune, no knock retard, fuel trims etc. The load on the motor on the highway is not the same as on the dyno and once again Tech 2 will grade the quality of the tune. Good Tuning takes time. Good Luck.

Mike,
Take your car into APE to diagnose the problem. You first need to figure out why your car is throwing codes. Perhaps it is something minor and you can get away without a full dyno tune.
Good luck,
Mark
