wat happens if i all ready have intake and exhust will the pcm know that it is there?

 

You will see good gains. The Mopar PCM works well with the bolt ons.

 

If you have a good CAI and a decent exhaust setup, that will improve breathing. The MAP and IAT will recognize the increased airflow and the PCM will compensate for it by adjusting fuel and timing. The aftermarket PCM's have a more agressive timing and fuel curve for added performance. The Mopar PCM was designed and tuned to run on a car with the other Mopar goodies - Iceman, header, Borla muffler, and a better cam for the SOHC's (except '95). So the closer you are to having the same setup, the better results you'll get. The AFX Street is based on similar components, and the AFX Race based on even better components like even bigger cam(s), long tube header, etc. There used to be a '95 SOHC AFX Race (only one)... think it accidentally got flashed quite a while back though...

There's also the option of a standalone setup like Megasquirt, which will give you much more control of the fuel and timing to fit your car, not a test car, if you have the time, money, and patience to spend at a dyno tuning it. For most folks, the aftermarket computers are plenty.

 

what is the deal with the map sensor anyways, what do you have to do to get that sensor accepting all the mods, i heard it causes problems with the more mods you do. will a mopar performance ecu fix it without doing anything to "upgrade/mod" the map sensor?

 

they only sell 91 out here in cali is that ok will it still work just as good becasue every one says that u need 95 or 93 or some odd ball thing like that

 

The AFX race is meant to run on 93 octane.

 

The MAP sensor is just a pressure sensor. The only time you're going to run into problems with it is with a turbo because it is not designed to read positive pressure, and the PCM is not programmed to deal with positive pressure. There are several ways around this, but that's another topic...

91 Octane should be fine with the Mopar PCM, but you might notice the knock sensor pulling timing some under heavy loads (probably wouldn't know it unless you were scanning at the time). If you ar at a higher altitude, you can runn a somewhat lower octane. The highest here is 91 octane as well, but I'm at 5000 feet...

 

so 91 should work then right?
does the mopar have a top speed limit on it.

 

Yes, but you aren't going to hit it.

 

right now i can only go about 110 or soo
