Hello, so I was wondering who out there is still doing the ecu programming for the turbo dodge cars. Years ago I came across a scocketed ecu that you can replace the chips on so it would me nice to find someone that works with those as well.

thanks

Or if you want to try your self.
MPTune can be used to create the chip bin file.
You can also add a flashable module you can change tunes from the cabin from a computer or even a Android phone

The flashable module plugs into an existing socketed ECU but is dependant on the ECU and how the person socketed,
LM - not flashable but you can swap chips or use ostrich,
SMEC- needs #11 pin modification and wires for A15,RW and PRG line as per Main Page - The Merkur Wiki
SBEC needs 32pin socketing not 28pin. SBEC2 is similar.

Let me know if you need more info, I have links available.

Hmmmm...

I have an SMEC I think. Might need to see if it has been rewired or repinned.

How hard is it to find another one if the one I have happens to be bad?

Granted, if it was rewired that's outside the SMEC unit right?

I'm trying to see that I can get a car started but it's a big mess. Some things got cut that shouldn't have, it sat around for a few years and may have gone bad and I need to trace a ton of wires to see if I can figure out if something is broken or missing.

If you need wiring diagrams let us know

Like the actual engine harness complete?

I'm almost to the point where I'm willing to rebuild the whole harness. Didn't get as much done today as I'd like.

I need,
Coil wiring,
Alternator wiring,
Tach signal,
Oil pressure,
Water Temp,
Tach signal wiring,
Fuel pump can be separate wiring,

There's some sort of ASD thing I don't understand yet and something else.
Basically the minimal needed to run the engine for a race car.

Some stuff has to hook up to the square thing to feed the inside gauge cluster...

Invade?

It's a 1985 frame, i believe a 1985 2.2 motor, 525 5 speed tranny, with Carburetor on the engine. And somehow setup to run by a 1989 L body M/T 2.2 TBI computer. SMEC has 5234928 on it. 655 on the chip inside it.

That was supposed to be "incase", stupid auto correct.

I have no idea how they are using A SMEC to run a carbureted engine unless they are only using it for ignition and fuel pump.
There is nothing in a carburetor for a computer to control unless you are concerned about emissions and it is a feedback carb, even then the carb itself has more control over fueling than the M/C solenoid.

Exactly what are they controlling?
Do you have pics of this engine and the distributor?
Does this engine have a fuel injected distributor?
Is this setup using an electric fuel pump?

I would be very inclined to believe it runs the fuel pump and the ignition and that's it. Some electrical data probably flows through on the way to the guage cluster too.

I can go take a ton of pictures for your benefit here.

Yep, Electric fuel pump (not sure if in the gas tank at the moment, but I am chasing spark currently). I think I have the fuel pump for it on the shelf and unit in it only has 3 pin connector so that's fuel sender only right?

I'll post 4 pictures of the gas pump I think I need to get into the fuel tank. Pretty sure it came out of the red race car chassis. After I post this I'll hitnup the shower and get food and I can go back and forth on here with a ton of pictures.

I can help you get this engine running and running properly, in order to do this I need to know exactly what we are working with.
The main thing I need to know is if the 85 engine we are working with was originally a 2.2L TBI engine or was always a 2.2L carbureted engine, the ignition systems/spark advance schedules are completely different and controlled completely different between the two.

That is why I asked for a pic of the distributor as a whole and with the cap off.
