well these are the #s i got off of my computer on the white sticker. i could not find any other codes or #s
service# 1227302
here are some others on the sticker
863041
160533041
m612027896
HNR
these were the only #S i could find can someone tell me what kind of computer i have?
i need to know so i can start getting some stuff to do my own proms. or if there isnt anything for me then i dont need to keep wasting my time thanks for any info

You have an ecm for a 88, FBod with a 2.8 auto.
To date I don't know of anyone that has a hac for that. So at this stage investigating installing a 1227730, and working with a 8D mask number bin seems like your only option.

 

1987 2.8 auto firebird so are you saying that its more work than its worth?

 

I have same ECM and I have'nt find any information about hacking this. You can build scantool (160baud) for this, if you already doesn't have one.

 

It isn't that much work. As for worth it? A lot depends how much effort you want to put into your eprom burning. The SD system will allow you tuning capabilities that you currently don't have. In fact, there really is nothing for your ECM in the ability to edit the BIN. So if you wish to modify your eprom, your only real alternatives are convert to SD 7730 ECM or convert to MAF 165 ECM.

I believe it would be easier to convert to SD and you do eliminate any MAF R&R issues, which can get expensive. After playing with both, I am still partial to tuning with the SD system. I find it easier to get direct results when I want to add some fuel/spark at one place in my RMP/Load range and reduce soem fuel/spark at another place in my RPM/Load range.

If you were to convert to SD, it would be very easy to modify the $8D SD BIN to work on your car and then "tweak it" to get better driveability, fuel economy and performance. It all depends on how much effort you want to put into it.

I personally have fun doing all these varous tests to see how it affects the engine; it is a labor of love for me.

 

Has anyone done this conversion 7302 -> 165 or 7730? I can't imagine, how V8 ECM can control 6-cyl. engine. But this swap is interesting, so if anyone have some information (what must be swapped/changed) abotu that, please write.

 

yeh so i should take out my computer and install a 7730. how much do u think it will cost? how many wires will have to be replaced
and will my connections still work?

 

If you want to maximize your ability to tune your engine, then YES you should convert your ECM.

An ECM will be fairly easy to obtain. Just go to any wrecking yard and look for an ECM from a 3.1 V6 Cavalier...they use the same 7730 ECM as the SD TPI cars. Should be fairly cheap. There are other 3.1 V6s that you can obtain the 7730 ECM from, but you have to be careful as many of the 3.1s also got a "404". Also, 3.1 V6 "W" bodies (Luminas, Regals, Grand Prix and Olds Cutlass) got a different ECM again (7727 I believe).

As for wiring, there is plenty of documentation on what the 7730 should look like. But, I don't have any info on the 303. I am sure Vader (Jeff) on the Tech/General Board can provide you with wiring diagrams for 303 ECM. Then it is a simple matter of figuring out what pins go where and what needs to be added/changed/deleted. Will most likely need some "plug-in connectors" from the harness to the ECM as I assume that your ECM probably has a different connector to the harness than a SD 7730. I would grab the wiring harness from the Cavalier too and consider modifying that or, at least, be a "donor"; especially if you can grab that cheap from a wrecking yard.

You might even be able to use the Memcal from the 3.1 V6 as your "base". May have to swap the knock sensor, as I suspect that is different too. You can confirm by contacting a local GM dealership and asking for the part numbers for your knock sensor and a knock sensor from a 3.1 V6 Cavalier. Same number, no difference. Different part number, most likely different.

Try reposting this question on the Tech/General Board and see what advice Vader can offer in the "conversion". But this strikes me a fairly simple conversion, and should follow the same basic principles as converting from MAF to SD...just different "originating" pins. But you would have the distinction of being the first V6 F-body to do this conversion. It could even become a popular conversion for V6 owners.
