Speedo is cable operated.

If you are looking to get that kind of power out of it you'll probably have to go MP PCM or to something like a megasquirt, I doubt the stock PCM could handle an engine with a radical cam, stroked, etc.

 

I'm running the stock converter.

If you plan on getting the 400 HP that that engine is capable of, you're going to have to go carb or stand-alone fuel management system. That stock PCM is not flashable, yet. There is a guy over on Turbo-Mopar.com that has cracked the code on the late 80's early 90's Chrysler SMECs and SBECs and they are now tunable (I'm running an '89 SMEC on my '04 2.4 SRT-4 turbo engine in my '88 Caravan). I asked him about the 92-95 V-8 PCMs and he said he's working on it. That's why I went with the adjustable fuel pressure regulator and return system for my 5.9 '94 Dakota. Upping the fuel pressure is an old school "add more fuel for more boost" trick.

I doubt the PCM cares what gears are in it. It's looking at MAP, TPS, and O2 for fuel management. If you step on the gas harder because you're running lower gears, it just compensates, except when you up the engine displacement. It can't compensate that much.

 

What about the Mopar Performance PCM...Still going to run out of gas, so to speak?

 

Yes, sorry...that's the plan, using the Mopar Performance PCM, if there's no readily available flash alternatives.

Or, gasp, go carburated. Funny, my initial plan was to go carburated...The crate motor has an M1 intake with a 750 Edelbrock carb on it already. But I was talked out of carb and into MPI by some members on the board. I'm used to ODBII tuning or at least ODBI with a large support network of tunes (my Grand National for example), so now I'm realizing the lack of options on pre-96 dakotas for tuning.

 

You might pick up 10-20 HP using the MP PCM. I doubt you're going to get anywhere near 400 HP.

Another option would be to use a '96 OBDII PCM and wiring harness. I'm not familiar with them so I don't know how tunable they are.

 

Well, that's disappointing....

Back to square 1 and carburation

Or is this an option: http://www.bgperformance.com/tuning-magnum-truck.aspx

 

Look into megasquirt stand alone fuel management ive never used it but heard good things.

 

I did some reading, and honestly, it scared me

The website/support forum reminds me of the old MAME arcade emulators and building a MAME setup...Lots and lots to learn, and lots of ways to screw up

 

F that. I'd just as soon walk.

Tuning is well worth learning. There's lots of support out there and a lot of people willing to help. A couple of years ago I didn't know squat about tuning but now it's second nature. Once you get your tune down you leave it alone. With a carburetor, every time the weather changes you'll be messing with it.

 

I agree. I'd much higher rather deal with learning the megasquirt system over using a carb.
