Try www.car-part.com , they also list a bunch, looks like alot of cars use the same the same computer .The site is a Hollander so it lists all cars that use the same part. Look for an "A" rating and a warranty on the lists, and have them send a pic of the sticker also before buying....

www.row52.com lists upullit yards, just do a search and add your email and you will be notified when a car comes into the system.

I think you are looking for an HKS or HKT
marked chip for the 86Z , i swapped in an HUL
from an 86 camaro and it also works great.

Here is a chip set on
Ebay.
Do not buy a Hyper Chip. They are a waste of money

Glad to Help!
You mean that smaller chip?
The CAL prom?

I tried the jet chip for a year and took it out.
It made the fan come on too early even for a 160
Stat and i didn't like the new ignition curves.
The engine didnt seem smooth like the factory chips.
Might have been a bad one?
The V6 Camaro chip has proven to be better than the stock z24 for my driving and i even picked up a mile or 2 to the gallon better on average.

Check the harness plug styles.
The 302 2.8 computer has the plug-ins on the end.
Thats what those chips are for.
The later ecu is like this one below.
The 7730 2.8 ecu has the harness entering at the rear on the long
back side like this one.

with the part number on it?
Re: Eprom chip ??

If I had the correct eprom id give you that too but the chip that came with the car is from the next body style z and it had a 3.1 so I doesn't work very well. Te ect reads -40. ive tested the circuits from the ecu to the sensor for shorts and opens- all ok. I even load tested them and installed a new sensor and Ecu. After doing some research found out it was the wrong prom. I guess they are pinned diffently ? I am a Cadillac technician so im used to very complex electrical issues but im out of my element with these systems.

Then it looks like you have the second design
Computer.
Going to have to find a used ecm with the same
2.8 v6 Part numbers on it.

The one i sent the link for does not come with chips in it.
If you cant find it on ebay you might try
Car-Part.com
Its a nation wide data base

No problem, just please keep us updated
on how you are doing with your Z.
I see quite a few computers available on Car-Part.com
Keep an eye out for 2.8 Cimarrons they have always been a good source for engine parts for my Z24.
