stupid_fast Posted April 9, 2019 Share Posted April 9, 2019 The all caps post is really annoying to read. Please structure your future posts better. There are no schematics available online for proprietary ECUs. The transistors are hitachi. From left to right D970, D970, B791, B566A You can figure out the resistor values by reading the color bands. The white resistor thing is marked 'ARW 0.5 ohmK JRM NK' The big one is marked 'RS3B 0.1 3 RIKEN Z' Your ECU may or may not work if the burned components are replaced, but its worth a try if you have the ability to do it.

Renewed 83' S130 Turbo Posted February 8, 2023 Share Posted February 8, 2023 Hi Stupid_Fast, I have an 83 S130 and I'm having problems with hesitation while driving. I think I have it narrowed down to the ECU. I changed from a CA ECU to a Fed ECU and it runs better. However, after time the hesitation is starting again. I'd like to get rid of the stock ECU setup all together. Do you know anyone in the SF Bay Area that can help me? I'm at my wits end with this. Any references would be much appreciated! Go Warriors, Giants and 49ers! Quote Link to comment Share on other sites More sharing options...
