3.1 MPFI modding

[Stonedified]

I've been thinking about replacing my cam, fuel injectors, and fuel pump on my 1993 Cutlass 3.1 MPFI, with higher performance versions...
If I replaced any or all of these, what other changes would I have to make?
And does anyone make an actual ECM programming module for my car?

If you want to tune, you will need a laptop, aldl cable (moates.net), software (tunerpro, moates.net as well), and a chip burner (moates.net). We have the files here you need.

hmm...is the laptop 100% necessary? and how much would the rest cost me, if you know off the top of your head roughly?

[SappySE107]

Hard to drive around with a desktop hooked up for logging. Under 200. You need a chip adapter and a chip, which I think its 35 bucks. Cable is 80. Burner...i forget.

true true...and thanks a bunch.
also, if I were to just replace the cam and pushrods...would my car run correctly without changing the tune, let alone perform better?

[SappySE107]

You can do a cam without a tune, it just won't be as good as it could be. The comp 260 or crane 260 would be fine. Pushrods only help.

I have the comp260 cam just not installed yet. FYI you will have to lower the motor some to install a cam. If you want to play with the computer without buying all that stuff just buy a chip from the store on this site.

awesome, thanks and btw what do you mean by lower the motor?

Unbolt the subframe and put it on jackstands and lift the car away from the motor
