EDIS-8 Troubleshooting

[gt eunuch]

Just a quick run down, hopefully someone can help me out.

As stated in an earlier thread, I am running MSII V3.0 ( MSII Rev 2.89100 ), Using EDIS and the Relay board.

Little back story here. Fresh install, just finished wiring, and tried to crank the car a week or so. All sensors are responding in Megatune, and I am getting fuel. I am however, not getting any spark at all, nor any response from the Tachometer in Megatune (stays at 0 RPMS)

Using Winscope and and a modified computer audio cable, I scoped the crank sensor, and everything looked pretty good at the sensor and at the EDIS controller itself. Using a multimeter, I am getting 12+ Volts with the key "on" and "cranking" at the coils and at the module itself.

I did notice, that on the relay board, if I take a voltmeter to the TACH port and I am getting 12v here, which seems a bit odd but this may be normal.

I have looked, but I cannot find a troubleshooting guide for EDIS, basically for everyone else when it does not work they swap wires on the VR Sensor, and everything works. This did not work for me. Any ideas guys? I am anxious to get this thing up and running!

Working on getting my MSQ, but my computer is being stupid. Megatune sees the file in the folder, but I cant see them in Windows Explorer... Grrr...

It is quite uncommon for EDIS to spook you.
1 VR sensor polarity swop. You have tried , but no change.
2 Check wiring. Some of us have managed to wire the EDIS backwards. Pin 1 is identified on the module.
3 Some ( if not all) EDIS have problems when spark crct resistance is too low. Each plug/wire combo needs => 5 kOhms
4 Be sure to have the capacitor to earth on each coil pack + feed ( => 10 µF/25 V)
5 Vr to wheel gap 0,5 to 2 mm

Are you really sure no spark ? Hook upp the plugs where you can SEE them and try

Good luck

I'd look at the PIP output with your 'scope, with the engine cranking. It should be approximately a square wave - 12 volts peak to peak.

Fixed it!

You guys will never believe what it was, it was a bad pin on the EDIS connector! The wire was broken off of the pin, but still wedged into the plastic connector (i.e. no connectivity)

SO I pulled apart an extra connector I had, stole the pin and put the new pin into the already wired connector and voi'la! Magic!

Thanks for everyone's help.

Now I have to figure out how to get this thing started/idling. She will turn over and spit and pop, but no actual run.
