Default conversion to 7165 computer

for those who have updated to the '7165......

did you follow the instructions on the eecis.udel.edu/~davis/z28/ecm_swap/ website?

i must be electronically challenged as some instructions from the repinning page are very confusing, especially when they (the instructions) are talking about splicing.

any additional insight would be greatly appreciated as i am to the point where i need clarification to complete the swap.

thanks for the help - this is a wonderful resource for this hobby

i don't have the copy in front of me now but....

the identification of the splicing steps is unclear and also there is mention of a"new" c12 and then later there's mention "remove-unused"

would you be amenable to a phone call say monday to discuss in more detail? if so email me off line with your phone number and i'll call you. my email is johndezman@hotmail.com

thanks

Are you doing this for tuning purposes (i.e. burning your own calibration), wanting a faster refresh rate for scan/logging data, or because you just want to? Reason I ask, and I know this wasn't your question, but a lot of us 85 owners went to the 730. It is actually a LOT cheaper in the future considering the price of a new MAF.

But I also understand that you might be set on using the 165. Let us know. -Matt-

updating for the faster baud rate and higher capacity of data points...

got the engine harness repinned/spliced per the web site.

since they did a camaro, they didn't have to contend with the digi dash.

does anyone have the pinouts for the connectors on an '87 7165 ecu and the 84 ecu?

any help appreciated

i bought a manifold, harness, fuel pump air cleaner, mass air etc from a 85 and also purchased the '87 '165 computer. i understood the '165 had a faster baud rate which influenced the number of samplings and because the chip had more memory more locations on the fuel map compared to the '85 computer. the engine wiring harness is/has already been modified per the instructions from the guy at udel web site.

shop doing work is telling me that the connectors for the digi dash do not plug into the '87 computer yet today i've talked to both fuel injection specialties and howell engine development and they tell me it should plug in!

getting confused and wanting the car back on the road......any first hand help appreciated.

dtorc4 did you do the computer conversion or have someone do it? did the dash plug into the 7165? or were there some changes necessary?
