NEED some clarification

In my last thread, I guess I really didn't specify what I was asking. Let me see if I can reword it. When you get your computer flashed with a power programmer or tuned, effectively...what does that take the place of? I.E...is that the same as getting a new chip or a new ECU, etc? This is my first V8 in years. Last car I had was an import tuner and I bought a new ECU and chip for it. Didn't know I had the option to get the computer reprogrammed.

We dont have chips. you get the PCM tuned and they can do the type of things like a chip. IE.. Adjust timing spark, fuel,shift points,speedo, tire size they can turn off Vats (security stuff). hope this helps.

furthermore....off the shelf tuners are great for ball park tunes....for example, they have tunes for bolt ons, tunes for cams, etc. these are VERY general tunes though, and you will either not get the full potential out of the car or possibley do something wrong(ex. get a tune for more timing when you are already getting some knock). the more you do to the car, the more specific the tune must be. A handheld programer may have a tune for "Bigger cam", but that in no way fine tunes it..engines react differently from one to the next and one tune may not work for your car. Lastly, spend the money, get HPtuners, or get someone that does to tune the car.

as mentioned... F-Body's haven't been "chipped" since 93 ... from 94 on they used Flash chips built onto the PCM/VCM ...

They computer's programmed via the diagnostic port (or if you get a mail order, you send your PCM in, they flash it, and then send it back)

OOOOOOOooooooooohhhhhh...

I gotcha now. That's why I was asking about the chip. I used to have a 93 Z28 and I kept seeing chips for it. Sorry to sound so novice @ this but hey if I don't ask, then I'm hurtin for not askin. thanks...one more thing. Would buying a venom 400 PCM for my LS1 be a bad thing or just something that isn't needed?

Well, me personally, I haven't gotten any of there products yet. But from what I have read and heard from people I know with different cars (civics, supra's, 350 Z's), they are very good products.

Click on that and check it out. I know 25% is a big number to put out there, but I'm still interested in checking it out, especially if it does what it says about working in conjunction with other mod's. It looks very promising. Even their nitrous kit looks hot!!! Anyway, let me know what you think...
