Great job and write-up. :thumbs:

Thank you :cheers:

There's two different PCM numbers available.
9354896 --- 99/00
12200411 ---- 01/03
Which one did you use?

hmm i dont know exactly, i know all the 99-02 PCM's are the same, those numbers you posted are throwing me off couse of the 03,

If the PCM is labeled with red/blue on the connectors it will work regardless of part number

Great write-up. Are there any problems with your guages? I have a 97 and was thinking of doing this swap but thought that I would lose my fuel guage.

i have the answer for ya!

Easy one is no, you do not lose your fuel guage.

You will have to use EFI Live for this. Depending on yoru mods and such, if yoru stock you can load up a 1999-02 Corvette Operating system with your Vin and your fuel guage will work, it will need to be re-called but a tuner can do this for you.

For me, i used EFI Lives custom operating system #5 and segment swapped the 99 vette fuel segment into the tune, so my fuel guage works just fine. PM me if you need more info id be glad to help you out in any way i can.

WOW! Very cool!

Why was it you wanted and or needed the newer PCM? Just curious - I have a '98 and wonder if it would be a bebefit to myself!

Thanks,Matt

read through this thread i explained most of it, in a nutshell if your gonna do heavy engine mods the newer PCM's are much much better for tuning

Hi there I helped with the installation of IMDS HUMS into the Bravo

Good Stuff :thumbs:

:lurk:

:thumbs: write up.
If I ever need to do.........its covered now:D

Please put this in my "sticky" DIY at the top of the page :cheers:

Id be honored!

Cause you said please.............done :thumbs:

wonder if there would be any benefit to me doing this. I'm putting a 427 in my '98.

If your putting in a 427 i woudnt even think about running that 98 PCM, im not far from you in jacksonville FL, if youd like more info shoot me a PM and ill send ya my number and we can talk it over :)

And Rick will talk it over with you. I know from 1st hand experience him and his friend Harrison are walking me through mine right now. When he 1st replied to a post I made a while back about this subject he posted pictures and I went :willy: holy crap Bat Man. But now that I have 3/4 of my wiring out and marked it really is not that bad. Now when I get it together and it won't run, or goes up in smoke, or lights, bells and sirens go off, this might be another story. :rofl: But after talking with Rick and Harrison I feel very good about the whole thing. My hat is off to both of them for the help they have given me to date. :yesnod: :flag:

This is still one of my favorite threads. :thumbs: You should consider making a conversion harness, eurospec1. I bet there are a few people that would pay for a plug and play way of making this happen.

:cheers:

(ps, of course if you make one, we'd be delighted to stock and sell it)

Don't think that could be easily done as the whole harness would have to be done.

I bought a label maker after seeing that thread and used some of his ideas when I re-did all of my wiring when I converted from an auto to a six-speed.

You would basically need to know what each wire does on the older PCM and What they do on the new one to figure out the pin assignments. Also need to know whether it came off of the blue or red terminal of the PCM.

No real short cuts when doing a job like that. :)
