1227165 ecu with custom code much better than stock ecu. (Page 11/26)

Good point, forgot about that. Best way around that would be to make an adapter to go between the 4cyl harness and the 7165 ecu. I could make something up fairly quickly if others are interested. I could do this for the v6 harness as well. This would make for an easier swap and allow to go back to the stock computer for whatever reason.



Do you have a source for the male end of the edge card type ECM connectors? If so, I'd be interested in an adapter, at least.

I do not have a source but I do make my own circuit boards. This connector style is easy to replicate. I have just finished designing an adapter to go between the 2.5 harness and the 7165. Hopefully there will be enough room for it. I will make one up and see if it will fit into one of my parts cars with the 2.5. The nice thing is that I can also work with a 7730 as well, but not today.

Well, I completed another trip to Douglas Wyo. from Walden CO. and fueled at Wheatland Wyo. I drove 140 miles and fueled the car with just 2.62 gallons. Averaged near 53 MPG with a 86 SE with 4 speed. Granted there was a good tailwind most of the way, but still nothing to laugh at. Before the ecu and code swap, I averaged 32 MPG on this exact trip, now with the swap, I average near 40 MPG without any help from the wind. I am happy with this swap so far.

If anyone is interested, I still have a couple nvram boards left for this swap.

Keep tuning my friends.

I'm interested as well. If you could PM me details, that would be great.

Received my nvram today and installed it . Ran the flash tool and installed the bin with my calibration on it through the aldl. She fired right up and ran better than with the ostrich with less cables. This is on a 3500 with 24# injectors and dis. We need to do more tuning but it's much better now. My SLC dyi2 is giving odd readings which might be an air leak in the exhaust.Thanks Chet for all the help

That is good to see this is working for you. Being that the ecm is a flash setup makes tuning easier and faster. No need to remove the ecu, erase and burn a new chip, then put everything back together. Not needing an emulator is also nice not having in the way.

Just ordered the bends to use the stock 3500 manifolds. I plan on doing 2.25 " short duels with spark arresters like supper traps. I have the stock 2.8 manifolds modified to work on 3500 but i have an air leak that is throwing the o2 reading off. Can i turn off the o2 sensor input till I get this problem solved?I am working on putting the 3100 $a1 timing over to $12p as the aluminum heads like less timing.It runs fine once warmed up but will float at idle with the headlights on.

Do you think the nvram would work in my 165 ecm from a 2.5 that is running a 1.5 engine. I have been using the auto prom and tuner pro and just getting the engine started and idling.
I have the innovate wb and installed an extra bung in the exhaust for the wb. My biggest problem is I am running the GM 2.5 eight pin distributor in the 1.5 engine and the distributor rotates the opposite direction of the 2.5. Needless to say the EST retards the spark instead of advancing. Can this be corrected in your code? In TPro I tried to run negative advance but can't go under zero. I also like the auto learn you spoke of. If you have more nvrams I have interest.
If this is inappropriate on this site I am sorry.

I got the advance problem solved today but I am still curious about the nvram and the code.
chetw77cruiser FEB 20, 08:19 PM
The code is installed on the nvam and they go hand in hand. The code can be set to run a 4 cylinder engine but would take a bit of tuning to get things right. I would need to take a look at your wiring pinout and compare to ehat this code needs. I am always up to a challange.
