The one Sean offers is around $400 - It's universal - and has eliminated some
of the quirks(like the O2 code problems) of the stock units.
If you're price shopping - you might pick up a used one for a little less.
I think most of the years can be interchanged with minor problems, but
it would help to stay in the 97 to 99 range.

Sean's PCM appears to blow something inside if if the injector clip comes loose. From my experience, this is a design flaw. If the clip comes loose and the unit fries, you are back to stock until you get a replacement.

I would call JonB and look into the earlier stock Viper PCM or the new Mopar one - less problems and great customer service from JonB

I used to have a 98 PCM in my garage. If I can find it, it's yours! (But I can't promise that I'll find it--I might not even still have it. I will look this weekend).

PS. I may have given it to the guy who bought my car, but I may have kept it. Can't remember which, so no promises. I bought it from a place that parted out Vipers. They have an internet site. Some combination of viper and parts.

I have never heard of any problems with the Roe PCM. I think maybe you are talking of some very isolated incedents with the VEC2. I have personally never had a problem with either.

I dropped the guy who I sold my car to a line. He says I did give him the PCM, and that I can forward his contact information to you. I don't know if he will want to sell it or give it to you. I paid $100 bucks for it, as an FYI, but I gave it to him for free. I will PM you his info. Maybe you'll get lucky!

That would be because there haven't been any problems with it.

So VEC2's burning out when an injector clip comes loose don't count as "problems"?

Roadkill, Icant find that Pcm on ebay. Can you send me a link or post it here??

Roadkill,

Oh, you're looking for a stock PCM? I have heard the PCM from the earlier cars are more "performance" oriented.

Try calling JonB at Parts Rack. I think its partsrack.com. he sells all sorts of takeoff Viper parts and would likely know which PCM you would want. If you want a factory one, call Viper Wizard Chuck Tator at Tators Dodge - he's a dealer and gives discounts

I ran a 96 PCM on my 01. Worked just fine.
Seemed like it pulled a little harder on the low end.

Supposedly the 96 is more aggressive with A/F.

I have heard the new Mopar unit is good also - the old ones often LOST power. Supposedly they fixed that.

Roadkill,

I may be wrong, but I *think* it's the 96 only PCM that is the "strong one". I dont know that 98 is the same?

Maybe someone else can chime in? JonB?

JonB won't be looking over here! I'm not sure what the differences are. Pre 2000 had a different OBD than 2000. I think 96-97 didn't have OBD at all. There was an old thread at VCA that answered these, and other, questions.

No JonB? Is he censored? /images/graemlins/smile.gif

You hit the nail on the head - it was the OBD that was the issue. Wasnt 97 an "intermediary" year on OBD and 98 was full OBD? I think that is why 96 is "the one"

I have a 97 PCM out of a GTS (gen-II) on my 96 RT.
96 was the first year for the OBD-II. I'm assuming the reason APEX switched
my original PCM for a 97, was to help the A/F - My car was running too lean.
Whatever the reason, with my 97 PCM + Dastek and Gen-II injectors and fuel
pump booster - I don't run lean.
