IMPORTANT: enter the case-INsensitive alphabetic (no numbers) code AND WRITE SOME SHORT summary of changes (below) if you are saving changes. (not required for previewing changes). Wiki-spamming is not tolerated, will be removed, so it does NOT even show up in history. Spammers go away now.

Summary of change:
'''Detailed Wiring/Config Information''' ---- http://www.vems.hu/files/KevinBlack/Todd%20P%20Wiring2.xls ---- '''Custom EC36/EC18 Wiring harness ''' * 12v IGN: 14 AWG to pin 25 * GND: 14 AWG to Pins 5,21,22,32,26 (ridiculous overkill) , sensor GND wires on branch (per UserGuide) to pin 26, all GND wires then go to 10 AWG wire to Engine Block, at OEM location for 1993-1998 VW 2.0 engine. * Injectors: Pins 7,19,8,20 * Ignition: Originally used Pin 35 Ch0 to dummy ignitor, eventually used Pins 34 and 36 (Coil 2 and Coil 3) * IAC wire ran to Pin 17, never used or plugged in to anything(tied up, no chance it was shorted to ground) * Analog 5 Pin EC18-16, Launch Control input using 2700 ohm pullup to pin EC36-29 * Analog 7 Pin EC18-12, tested for WOT shift but eventually used for input from Autronic Air/Fuel Analyzer. * Autronic Air/Fuel Analyzer analog ground is connected to chassis ground (afterthought) * Eventually switched pins between 16(now Wideband) and 12(now LC), to allow the wideband to be logged in Megatune "Misc Voltage 1" * Ch4 Output Pin 3 - Tach, 1000 ohm pull-up to 12v. * Changed to Ch 0 Pin 4 (to test output, after that found bad instrument cluster and changed) * Ch5 Output Pin 15 - wire triggers OEM fuel pump relay and additional relay powering 1) Injectors 2) Wideband Pin 3 and Flyback to VEMS and FJO Driver. * Ch6 Output Pin 31 Fan Relay * Ch7 Output Pin 30 Shift Light * Stepper outputs - wired as spares in harness, never connected to anything. ---- custom '''FJO fuel injector driver''' * Connection = (4) in, (4) out, (1) GND (12 AWG) and (1) INJ Power (I assume for Flyback) * Flyback wire to VEMS is still present ** do you know that injector outputs can only pull to ground ? (that is pullup might be needed, perhaps internal in the FJO injector driver, did you think about this ? Measure voltage when inj output inactive) *** Yes, and No. All I know is that the FJO Injector Driver is a commercial unit being used by thousands of users, many by (modified) OEM Honda ECU applications (If this helps answer your question?) and are installed the same way as this one. * dig up some FJO docs * Measure the inj output ** Ignition ON (FJO supply present) ** ECU injector output disconnected from FJO input ** measure DC voltage on FJO input (if it's +5V or +12V). ** optional: pull FJO input to ground with a 1k resistor, *** again: measure DC voltage on FJO input (if it's +5V or +12V). **** TODO on Wednesday
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
