Hello. I have a 1982 Ninety Eight that was stock until I put a 83 hurst vin 9 engine and carb in. It's running alright I guess with the Ninety Eight ecu/prom. I ordered a new ecu for the vin 9 hurst and it was the same part number as the ninety eight and didn't come with a prom. I can't seem to find any info on the part number. All I can find is hypertech and that seems to be generic to either vin Y and 9 engines. I really want a stock chip as I figure it is properly accounting for the difference in cams.. Thank you in advance for any info.

 

My old listing shows pt # 31211 for the H/O(9) only chip, a regular Cutlass/Regal 307(Y) shows 323002. I had one of their "stage 3" chips in my '87 GN, along with some other mods like a ram-air set up. It sure woke up that car!! 13.02 @ 107! It wouldn't have taken to much more to get into the high 12s. I couldn't afford the speeding tickets though!!

 

Part number for VIN-9 EPROM is 1226360... Reference listing below...

 

Thank you. It doesn't seem like they exist anymore even with the part number. My only hope seems to be lucking out on a used one or a hypertech that I'm unsure about.
