I pulled 4 from the Pick and Pull, and they were all Rebuilt ( so the original had failed).Īs I mentioned in your other post, Ryan at Sinister Performance is the man to go to for this programming. It does use the same ECM as the Park Ave / Bonneville / TransSport- but of course the PROM is programmed differently.

I finally tracked down an OBDI scanner that would almost work, but the Riviera is a real oddball. You're lucky if your scanner will read it. Many of the Error codes, etc in your ECM are OBDII style. It's confusing, but GM was in a transition period. Unfortunately, your ECM is OBDI, but the stock installation used an OBDII style of ALDL connector. If I can't find someone to burn an EPROM for this I'll had a lot of parts for sale. I have a Tech 2 scanner that works with it. really should have the $5B7 but is marked TBD Some of the values would be entered wrong. Even though it is much more popular than the 1994/1995 3800 PCMs I have found a few issues with the Tuner Pro XDF. You can read the stock prom for a base BIN. But have found if the prom is not read properly, it won t run anyway.Īlso you may have a hard time finding a base BIN and exchange files(different tuner software uses different names for it). The memcal also has calibration chips on it. And suggest using the mentioned Moats adapter. I had to rape a memcal to make an adapter that I soldered a ZIF socket to. The 1993 PCM that I'm using uses the above mentioned "memcal". I have been using the 256 version and have been able to rewrite many times. Highly suggest a EEprom like SST 27sf512. Even with a UV eraser, they don't like to be rewritten. Unless you have a UV eraser, you can't edit the stock proms.

I have to admit, it was the smoothest 3800 that I have run. Through all the reading that I had done the 1995 3800SC was series 1. I was running a 1993 Series 1 that had a 1995 charger on it. custom axles, HP Tuners VCM Suite.Ĩ7GT - ALL OUT 3.4L Turbocharged engine, Garrett Hybrid Turbo, MSD ign., modified TH125H " THE BLACK PARALYZER" -87GT 3800SC Series III engine, custom ZZP /Frozen Boost Intercooler setup, 3.4" Pulley, Northstar TB, LS1 MAF, 3" Spintech/Hedman Exhaust, Autolite 104's, MSD wires, Custom CAI, 4T65eHD w. This will make memory chip insertion and removal easy. If your computer has one of these Memcal's then there is no separate eprom socket and I recommend that you purchase the Moates adapter and a zif socket. The later OBD 1.5 ECM's employed a memcal where the eprom was soldered in and it unfastens as a unit. Assume that this is correct you need to find someone that has the editing file for that specific one year ECM program. If this is true, it would surprise me that GM did not do the change over in that model year. If that ECM uses eproms and its not flash based, the 95 3800SC might be the only series II that used OBD 1.5. I have a 3800 SC series 1, with 4T60E auto that came out of a 1995 Buick Riviera. So I know this thread is a few years old, but is anyone here able to program changes for me?
