fairladyME Posted January 29, 2010 Share Posted January 29, 2010 I'm running a Jim Wolf reprogrammed Z31 ECU with my L series and I I had a nasty short in my original wiring and sent 12V to some places on the ECU that it didn't like. I have a new ECU coming to and I am going to swap my JWT EPROM into the new one. My question is this. Does anybody know any other modifications they make to the ECU besides burning a chip for it? The one place I had in mind was the AFM circuit since they converted it to a MAF. I guess I'm just wondering if they did anything magical to my ECU when I mailed it to them to be reprogrammed or if they just slapped a new EPROM into it.

Kash Posted February 4, 2010 Share Posted February 4, 2010 Are you getting an ecu from the 280zxt? If so, why not a z31 ecu? This way you don't have to worry about the maf circuit. Quote Link to comment Share on other sites More sharing options...

fairladyME Posted February 4, 2010 Author Share Posted February 4, 2010 Its an ECU from a 1988 300ZX. My car is set up with the Cobra MAF, 440cc injectors and the old z31 ECU that I had in it was programmed for these mods. My concern was the the voltage properties of the Nissan MAF and Ford MAF are different from what I've read. Quote Link to comment Share on other sites More sharing options...
