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.

Bump for the fact that this appears to be every part as effective as a '7730 swap.

The code is based on $12P for the Delco '808, which is the Holden crippled '165.

The $12P code itself: https://pcmhacking.net/foru...topic.php?f=27&t=356
The NVRAM board: https://pcmhacking.net/foru...opic.php?f=14&t=3612
Chet's 2.8 tune: https://pcmhacking.net/foru...p?f=7&t=375&start=10 bottom of the page.

I'll likely go down this avenue for my 3.4 soon and will report back later if anyone is interested.

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

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.

Been away for quite a while. You know, life and all that.
Who is out there still using this and how has it worked for you?

Hi Chet, about ready to install on my 88 2.5 just need to crimp the ends on the connectors. Need to mount my cnp ignition.

Hey there Chet.

Still running this on both my cars. Working very well.
https://www.fiero.nl/forum/...L/000077-7.html#p263

I'm just worried the power cell in the Dallas chip on the daughterboard will die soon.
I need to get my BIN programmed onto a Memcal before then.

Good point on battery life. If I remember correctly, the battery in this is good for about 10 years. Luckily they are still available for about 40 greenbacks at Mouser electronics.

Yes... but I don't have a programmer to set it up for use.

Let me dig my gear out. I may be able to take care of that for you or anyone else that needs it done.

Hi Tony - I have a programmer so I can do it for you, as long as you have your code (we can always dump if directly from the unit as well).

Kind of interesting though that they went this way vs using NVRAM...unless there is a technical reason - to be fair I didn't look into this, just what I read here so far.

edit: hmmm, not sure what the function of the battery would be for since the DS1245Y-70IND+ is a NVSRAM unit, so it shouldn't need a battery to retain it's memory as that is the main feature of the NV term (Non-volatile). I seem to be missing something - I use NVRAM all the time in my other hobby and it retains it's memory with no battery (use it to replace the conventional RAM and batteries to eliminate the need for batteries and possible future damage to the PCB due to them leaking).

Good to know for when the time comes to do this.
