untill there program , i woulda said doing the 99 swap was the best way to go


but now hp all the way , it even saves you from buying the 99-02 knock sensor , harness connector end , and trying to wire it up


plus tuning to get more power , it cost more upfront , but in the end youve saved alot

the 99 ECM is designe to run with 99 injectors so just tossing the 99 ECM in won't do any good. yes its designed to run with no EGR bust there are other differences in the 2 years of cars.

Clearly you don't know what you're talking about.

Have you put in a 1999 PCM into a 1998 successfully?

The misinformation on the .org is spreading like wildfire, it seems.

Yes I'm coming off as a bit of a prick here but I never give advice that I don't have any personal experience with.

And I only know of one or two people with experience with the 99 PCM swap - me being the first to have flashed a 99 PCM into a 1998 box, and run it for 3 years flawlessly.

Keep giving your advice I guess - this post isn't going to stop you and all you'll probably do is flame me which is fine. I bow down to your ub3r sw33r advice and experience in this matter.

i have experienced this first hand and yes your coming off as a prick. maybe you shouldn't shoot off your mouth untill you actually ask about a persons experience or lack of. also he's not asking about re-flashing, he's asking about putting a 99 into a 98. did you stop to think about that?? hence why i said JUST putting a 99 into a 98 is not going to work.

Yes, and it's the same damn result

Remove PCM, install 2 wire knock sensor, put in new PCM. That easy. Been there done that.

3 years ago.

You make this seem like it's something difficult, it takes an hour to do.

Reflasing the pcm to a 99 and putting in a 99 pcm is the same thing. Please explain how it is different. When you reflash it, it is now functioning as a 99, not just getting an EGR delete function. All the parameters are now 99. Exact same thing.

Some may argue that the injector drivers in the 99 PCM are different - but they are not. It's a transitional PCM... open one up and look.

Again - I don't give advice unless I have 100% experience in the matter. You can run low imp injectors on a 1999 PCM no problem whatsoever. Don't try it with a 2000.

ok now that's a little more civil. i have dealt with the PCM issues in a 98, 99 and 00+ and found that you couldn't just swap them in at will. certain other parts had to be changed. as was mentioned previous the knock sensor was one, slight differences in the injectors was another issue and of course the dreaded EGR. of course the 00+ is dif again with the BCM. i believe his question was, can he just put it in and go. answer is, and you've just stated it above....no he can't. i never made anything out to be hard. you did that yourself.

how do you know chris you were the first?

i know of 3 people off the top of my head with the 99 set up.


anyways, my advice is go with the HP tuners stuff.

Jake - I know others achieved the swap but did they REFLASH. No. I was the first.

that is basically it yes. you give them the vehicle info, they get the part# and they re-flash it.

I'm not sure how long ago I did my first '99 ECM swap...... or even how long ago I did my first '99 ECM reflash...... but its been a few years (well before I worked @ HighRev..... and that was 2.5 years ago)...... I *believe* my first one was Jason HanZenRider's '98 Z when we S/Ced it......

If you put the '99 software into a '98 ECM, there are no problems with the injectors...... since your still using all the stock hardware.

If you put a '99 ECM into a '98 Vehicle, you *SHOULD* also change the injectors, but as Chris has pointed out, he's ran the '99ECM with Low Imp. Injectors w/o any problems (if it was going to damage the ECM or Injectors, it surly would have in 3 years)
