The title basically says it. How is the 98 PCM different from the 99+?? Why is hypertech the only company that makes a programmer for them? I just ordered the hypertech for my 98... I'll use it till I get headers and a cam, at which point I'll sell it and get a professional tune. I also just got a ported and descreened MAF sensor, and I'm reading all over that this is a bad idea...why?

Basically lying to the computer is always bad.

ported maf's lie to the computer

the 1998 computer is unique, so it takes the aftermarket longer to develop a product for it, since the 99-02 computers are the same, = more $$$

Hi

Superchips has a hand held tuner for the 98. Also, Vinci is just about to release one.

Your right, superchips does have one for the 98, but it is similar to the hypertech, that are only designed for stock, gear, intake and exhaust upgrades, more than that, then you have outgrown what that tuner was designed for.

I look forward to see how the vinci tuner works for the 98 guys.

Is it possible to swap out the computer from the 98 T/A and install a unit from a 99-02 unit, as I also have a 98 T/A. Or by doing this would it set off a bunch of codes? Further, does anyone recommend descreening the factory MAF, or is that a bad idea, as I hear it back and forth.

The processor in the 98 PCM is slower. I have never actually heard of it making a difference. And you can't copy a later year OS on a 98 PCM. There are a lot of OS differences in later years.

I'll believe it when I see it. They have been saying this for a while, just like the predator for the 98's.

Why wait for handhelds. For a little more money you can get hptuners or the like.

Iv'e seen it first hand. They offerered to let me test it for a week or two on the street to see how the part-throttle performed, but two things cropped up: 1) I need to start with a stock program (which my aftermarket tuners never gave me) and 2) the gear scaling in the handheld wasn't quite right a couple of weeks ago and since I don't have stock gears they wanted to hold off until that was fixed.

Now my car is in the shop waiting to have a valvejob and the heads milled flat. Not sure when my car will be ready, nor if the offer will still be good to test the unit at that time. Then I need to find a stock tune for less than an arm.
