Basically the same thing. I like the 7165 because it fits in the 7170 tray and uses the same ecm plugs. More of a plug and play operation. I will check to see if the code I use is compatible with this nvram board. What I am making is a little bit cheaper but requires the memcal to be modified.
If anyone wants to try this nvram with the modified 8D code, I have a base tune from my 86 GT with 4 speed. Transfer most of the parameters to the nvram code and thisng should work.

what kind of re-pinning have you done to the stock bulkhead connector? im intrigued or was there any, because it doesnt seem that you messed with the engine wiring harness

I did not have to re-pin the bulkhead connector. All I needed t do was re-pin the ecm connector, and that really only needed about 5 wires to be moved and a couple to be removed. For instance, the stock ecm used two signal lines from the map sensor, whereas the 7165 only needs one. Most everything else can stay in their normal location. This makes going back to the stock ecm really easy if needed.

Is this the print for the 7165 that you used?

From what I can see(low resolution), this is mostly what I used. Of course some of the input and output pins have been changed for other functions. For instance, the air divert valve is now the fan relay control. A3 is now a programable output instead of used for the canister purge valve.
Overall, most of the wiring is the same. I will make a pinout chart to go between the 7170 and the 7165.

This is an excellent thing to do I think. I have a weather pack pin remover on the way so I can remove and replace some broken connectors.
I have a swapped a 3.4 into 2.8 attire for my 88 Duke car. Might as well install a better ECM and programming. This might improve my 3.4 a bit more.
I will stay tuned for more information.

Just went to Slez Bay to look at 1227165 ECM's. Looks like they run between 85.00 -150.00 for the most part.[This message has been edited by josef644 (edited 10-23-2011).]

Can you make me a nvram for an automatic car? I have an 86 automatic with 3.33 finals

I will need to get some parts to make one up. I will let folks know how much the nvram setup costs when completed. Keep in mind that all I have are manuals, no automatics. That shouldn't be a problem. With the tcc you will be giving up one of the programable outputs.

Not a problem as I want to pretty well keep the set up as is untill I get about 5K on this new rebuild. Has about 200 miles on it now.[This message has been edited by josef644 (edited 10-23-2011).]
