Problem Description
At any rpm, (tested up to 4000), I loose ignition, fuel pump and fuel injector activity for a very brief split second. Feels like I have shut the board off and on again super fast. Megatune log shows rpm drop to 0 during most of the events but not all seem to get recorded. Megatune shows no resets. With the board out of the truck and on the test bench, fault is the same. For the rest of this page, assume the readings and observations are all off the test bench with nothing but the fuel pump relay and input trigger connected. There are no ign coils, no injectors, no wb02, no idle solenoid, no sensors, nothing is hooked up.
Things I know are not at fault
- Ground- I have 2 gnd wires and 4 gnd5 wires. Only load is the fuel pump relay, NOTHING ELSE is connected.
- Firmware version- I have tried every firmware version released since 1.0.12, problem has been no different.
- Power supply- Problem happens the same in the truck with 14v, just using a car battery reading 12.4v, or a computer power supply reading 11.6v.
- Input trigger runout- Originally used a VR sensor and set the board up for that. No suggestions would help. Changed over to Hall type and used an optical trigger (will detail that later) problem is the same. Used pc signal generator, problem no different.
