Status: V3.3 Serial #1973 up and running, but with many issues.
Initial Issues:
1) P259 Ch5 used for Fuel pump Relay trigger, this would work when priming. But with the engine cranking, the relay would not activate. I later changed the output to Inj 5 (Ch. 4) and it worked OK.
2) Tach output(500 ohm pullup from Webshop) works, but the Tach will sporadically jump up very high, example jump to 4000 rpm at idle instead of 1000. I changed the Pull-up to 100 Ohms, but did not fix.
3) LCD screen will display normally after start-up. But after a few minutes the LCD data will get scrambled (? marks, data numbers and letters all over the place)
4) Car was running and driving, for about 6 hours of total run time. Several runs were made to 240 kpa(absolute) boost.
Then injector #1 (Ch.0) stuck on during a 1-2 gear power run. Output dead short to Ground.
Took box apart to replace FET, decided instead to change wire to another injector output (Inj 6, Ch. 5).
Engine started and ran fine. Made a couple boost runs to 200 to 210 kpa.
But when making more runs at 220-240 kpa, the ECU "cuts out" and engine stumbles badly. (ecu loses communication, and you can see this in Megalogviewer when you graph the "time" and "seconds".
Comments/Background
- Is it possible that some of these issues are related? or caused by static damage? (I had to take the ecu apart 4-5 times over the course of the engine startup.)
- Flyback and Grounds checked out OK visual and resistance .1 to .3 Ohm.
- Fuel injectors are High-Z 1000cc, Bosch re-made in USA.
