I had previous experience with the module from Jet in a Ranger. It wasn't good. :-(
I checked with people in this Forum on the Mopar PCM. They are more expensive but they work. I don't know how much the h.p. will go up because I just ordered mine yesterday. Also, Mopar advises against towing with it due to the timing advance. It may make your engine ping when towing. KRC sells a retard device for app. $200 to work with the Mopar PCM so you can tow and use regular gas, but you will spend over $600 for the PCM, dealer flash, and retard box.
Hypertech makes a plug in module like the one Jet sells. You can tow with it but no one other than Hypertech, can give me any hard evidence of what good it does. I prefer to see 1/4 mile times or dyno charts before I buy something. I would buy the Hypertech version over the Jet module. Just my $.02 worth.

Hey Wayne, what is the dealer flash you are talking about? I have a Mopar PCM on the way also for my truck, as far as I understood, all I had to do was swap computers. BTW, got my PCM for $100, bought it used from the Dakota Mailing list.
BTW, do you know of a website for the KRC retard? Wonder if the Crane Fire Ball HI-6 with retard module would be the same concept?

Kevin,
I don't think you have to worry about the dealer flash on a '95. Only '97 or '98 and later have to do that. Those have to go to the dealer and have the mileage (and vin # I think) flashed on them before installing or they will set a code. The flash costs about $50-$75 dollars I am told.
You got a good deal on the PCM. I never run into those deals.
For KRC Performance click on links on the top of the home page. Then select parts. KRC Performance is on the list. I ordered my PCM from them and that is when he told me about the retard box. I didn't see it anywhere on his web site. If you find out the Crane Fire Ball will work, please let me know.

The Crane HI-6R FireBall with TRC-2 (timing retard control) module does not have a specific application for Mopar after 1986. Plus involves cutting some wiring.
I looked at Jacobs last night and sent them an email since their systems always have a "no cutting" gaurantee. They have a timing retard system also.

One of the things a "chip" (PCM or PTM) does is advance the timing more than the factory setting. This greater timing advance will cause pinging in certain situations such as under load (like climbing a hill or pulling a trailer) or using regular gas. With any of these chips, you will have to use higher octane gas. If you want the benefits of the Mopar PCM for racing purposes but don't want to use premium gas all the time or you want to pull a trailer, you can put a device in to retard the advance a few degrees. Then you can adjust it back to maximum advance as allowed by the computer when you want it.

Good explination. So what's "pinging"?
I've been driving around in a Corolla for the last few years... Never really cared about engines. Learning.

It is a clattering sound that you will hear coming from the engine when under load such as climbing a hill or accelerating. The noise is caused by the mixture in the cylinders igniting before should. It can be caused by several things such as lean mixture, carbon build up in the cylinder head (stays hot enough to ignite the incoming mixture), too much spark advance, and low octane gas to name a few. There is a lot more to it than that but this is the quickest explanation I can think of. The danger is pistons can be ruined if it goes on too long or is too violent. We burnt 5 of the 8 pistons in my sons car when we put our first blower on it and tried to run with too much timing advance. We could barely hear the pinging/clattering but it was bad enough.

What do you think would be better for the 4.7? I heard from where I work that the mopar computers will compensate for what the jet chip is doing over time. Plus if you get a Mopar PCM, It would affect your warrenty.

With the Mopar PCM's, they're covered under the factory warranty. (The dealers need to "flash" them with your VIN and Odometer readings anyway.)
On the 5.2/5.9L engines, the Mopar PCM works best. On the 4.7L, it's rather mixed feelings right now: Jet Stage-II vs. Mopar. (And I don't think that Mopar has a Performance PCM available for the '01 models yet...could be mistaken though.)

Bernd, do they have to flash a 95 model PCM? What happens if they don't flash it?

Bernd,
The last I knew of the Mopar 4.7 PCM's they were on backorder till August. As for the '01 PCM I don't think they are available yet.

Don't know if they've been released yet...but Marty (KRC Performance) already does the custom flashes for the factory PCM's...4.7L included.
