Default 1992 ECM Question

My car appears to not have a original ECM unit. I have a AC Delco replacement.

Can these units be modified / programmed / tuned like the original equipment or do I need to find a original 92 units off of fleabay ?

Reason I ask is my car will be going to the tuner with the next 3 or so weeks. H/C/I/TB/Injector swap is going to happen within the week.

Attached are a couple of pics of whats installed in my car.

Is exactly the same as the original unit. Has a chip (memcal ) inside that can be reprogrammed or more commonly replaced with a chip holding your new tune.

Check out pcmforless. They can provide you a newly tuned chip for your ECM and upgrade it as you add mods to your vehicle.

Its actually going to TPIS in Tempe (The entire car). They are local for me.

I would do the PCM for less however I do not have flow numbers for the heads and in order to get a good tune they would need to know how much they actually flow.

TPIS being local (with a dyno) I can get all the mods done , flatbed the car to their shop and drop it off.
