ECM prom IDs for my 87 TPI 350

[Guest Anonymous]

I need some help in "ID"ing the prom currently installed in the ECM (computer). It is a ABUT8562. The origional 305 TPI engine was supposed to have came from an 87 Z28 Camaro. That engine is history and was replaced with a crate 350 with a mild cam that was supposed to yield about 300HP with the TPI set-up. It is working just fine so

far and I am getting good gas mileage.The car was smog certified under the old 305 setup. I Know---If its not broke- don't fix it. But thats not what we are about is it?

 

QUESTION 1: Where can I get a listing on proms so I can get one more suited for the 350? I tried thirdgen.org.Couldn't find my prom.

 

Question 2: Can the injectors for the 305 handle a 300 - 400 Hp 350?

 

Question 3: Whats the word on this new PC program that lets you program your ECM?

 

Thanks !! You troops have given me good data in the past and I am going to keep my 71 Z.

EDIT: Well, I'm a 'tard. I was looking at another thread, and noticed the "similar threads" line at the bottom, clicked, and then just didn't notice the date. Oh, well, I'll leave it here in case somebody could use the links.

For a reference on what ECU is what, check http://www.cruzers.com/~ludis/ under the "C3" section. It's likely a 1227165 (the part number changed to 16198259 a couple of years ago). It was used in the 1986 2.0 L4 TBI “P†LQ5 w/ MT,

the 1986-89 5.0 V8 TPI “F†LB9, the 1986-89 5.7 V8 TPI “8†L98, the 1987-91 truck 2.5 L4 TBI “E†LN8 and the 1991 truck 2.5 L4 TBI “A†L38. Try a google on "1227165".

 

An excellent place to check out is the "DIY EFI" forum at Thirdgen.org ( http://www.thirdgen.org/techbb2/forumdisplay.php?s=&forumid=16 ). There are thousands of excellent threads concerning programming. There's also a FAQ at the top level of the site, as well as several "Intro to PROM burning" articles.

 

Also, check out http://www.diy-efi.org/gmecm/ under the FAQ and the "Papers" sections. Also, the FTP site has lots of .bins (the binary images of the eprom chips themselves, the "programming" you want to modify.
