And pretty much most/all? of what they are talking about is doing this with the 2.8 v6 and distributor, not the four with a distributor, and not the four with the DIS.

I have this ECM setup on the SD4 with distributor and running a FAST EFI throttle body.

Later... I changed clutch and transmission and built a multi-port FI system for the ECM.

Question for Tony (fierosound) or anybody else who'd care to comment...
Is it worthwhile going this route for an '88 Formula 2.8 5-spd with 1:6 roller-tip rockers and ported exhaust manifolds?
This car has always appeared to run fine, but I can't help but wonder if an ECU tweak might allow it to run "finer".
It's not something I'm wanting to do anytime soon, but I thought it best to ask now to help prevent this thread from becoming archived.

Hi Patrick this ecm upgrade is easier to do as you have less wires to move. The software is has more options like running boost or higher resolution tables on fuel and spark 9600 rpm. There are other options like flex fuel or flat shifting but these are all things that add to the learning curve. The tuning is a little bit different but the end result for me was great being able to tune without removing chips makes so much easier. I suggest download tunerpro and the othor links from above and check it out. They have a pdf of beginners and advanced tuning read through them and check out the forum then make your decision. Have fun

jdv, you've lost me with the first sentence!  Which ECM upgrade is "easier to do" than which ECM upgrade?

with the 7165 you use the stock ecm tray and you have to move i think 4 wires.
Note to self don't post in the middle of the night when you wake up to get something to drink.

With the few mods you have, the stock computer can handle that no problem.
The 7165 ECM is a faster processor (8192 baud vs 160 baud) and requires a wideband O2 sensor.
Ultimately, all you may notice is that the engine will be rid of that "hunting idle" we sometimes have.
You'd need the 1227165 ECM, the NVRAM board, and a Wideband O2 sensor for the install.
Then TunerPro RT and correct files.
Get the 12-pin ALDL interface. http://www.reddevilriver.com/aldl.html[This message has been edited by fierosound (edited 01-27-2020).]

Tony, I've never had a hunting idle... so it would appear that perhaps it wouldn't be worth the hassle to swap out the stock ECU.
If the HP won't be doubled and/or the MPG tripled, what would be the point?

I agree.
Now with my Indy, I needed something that I could program to control the MPFI system I built.
A carburetor is basically a controlled fuel leak, so the computer controlled fuel injection is working much better.  [This message has been edited by fierosound (edited 02-01-2020).]
