I have 7 ECMs available for the 7730 Upgrade. These include the Calpaks and the pigtails.

Original info on this upgrade is here. This upgrade helps the Fiero to run more stable, supports many different engines, and supports DIS ignition.

You need to remove the Calpak and have Darth Fiero reprogram the chip for your particular application.



I accept paypal, and have sold several of these on the mall in the past.

Do any of them have a TPI V8 calibration?

No. All of these came out of Pontiac 6000, Chevy Berettas and a Buick. 2.8 or 3.1 V6 engines.

If I am not mistaken though, the Calpaks can be programmed to run a V8 TPI. Would need to ask Darth on that one.

Bump. Need these gone.

2 are sold and shipped.

You are quite welcome. Glad you got it OK.

Bump.

3 left.

You need the v8 calpak to run a v8 or you can modify a v6 calpak, but it's usually easier just to find an 8 cylinder one. There is some hard coding, so to speak, in the calpak that affects fuel delivery.

Good price though, I may take one to keep as a spare in the trailer for the race car. I'll let you know

Thank you for the updated information...

I am keeping one of these for myself so I can install the 7730 ECM in my 86SE. Hoping to have that completed before Dells.. Not sure yet. I have the capability to burn my own Calpak, but no code for it. Wonder if Darth would send me the file so I could burn my own.

The calpak itself, not the actual EPROM, can do a couple of things. The EST circuitry can be on it as well as some circuitry that hard codes some fueling factors. the forum thirdgen.org has a really good resource on what works, what doesn't, and how to do some workarounds.
