MS3X controlling but no oil/coolant temp or speedo readings at the gauges
Looking for some troubleshooting advice from MS3 users. I have a MS-3X installed in parallel with the factory ECU in order to keep the gauges functional (MS3 has its own sensors). The only gauges that work are fuel and oil pressure. Wiring checks out for sensor continuity, ECU grounds and power. Spun the speed sensor with a drill, nothing.
Everything was working before the MS-3X. Using a crank trigger vice distributor for timing but the issues existed before the mod.
The check engine light works ( as it should) and that tells me the ECU is ok. What is are the speedo, oil/coolant temp gauges looking for, signal wise?
