Changes by last author:

Changed:
* MembersPage/EricN/Trigger - inputtrigger
* MembersPage/EricN/Trigger - Optical inputtrigger
Added:
* MembersPage/EricN/Fixed - solved issues with no other home

* MembersPage/EricN/ManualWork - I am trying to help finish the manual, everything I do will get posted here, hopefully then it can be proof read and then taken out and loaded into the manual. (I have no clue/ability to do it myself)

* MembersPage/EricN/ConfigReference - Pasted my config with the links to the page in the manual for each config variable, sort of a checklist for the missing stuff and a lazy mans table of contents.

Deleted:
P259 likely dead, pulling internal 5V supply shared by P259 and the LM1815 (VR trigger chip) down - preventing triggering

From the symptoms, and the fact that GND was ripped for some time, this is likely.

To confirm this, after disassembling, power up the device (don't forget all GND and GND5 connections) and measure the LM1815 supply (pin8 should measure +5V from measured from GND). Maybe removing only endplate allows this measurement (especially easy if no MAP sensor).

*Measured the voltage at pin 8 to gnd the other day, it was .88v if I remember right. May have measured the wrong pin because I did it off the top of my head but I'm sure pin 8 was the one I choose. Either way, checked all LM1815 pins, none have 5 volts.

Tried to start the truck the other day

* MegaTune comm works

* LCD works

* no rpm signal or wheel error

* no fuel pump activity (untill I hit the brake pedal, then it wouldnt shut off) nothing working as far as I could tell.

* Put the ecu on my test bench, all sensors readings look fine in megatune, I can upload firmware, everything looks ok untill I try and do an mdh command.

* I noticed the fuel pump channel, p259 ch 5 doesnt turn on. Tried some other channels, none of the P259 channels work at all

* I went out to the truck to check the wiring, found 1 wire ripped out of ecu, the EC36 pin 26 ground wire. Connected.

*Disabled all the channels since mdh.. can only control free outputs.mdh can not manipulate channels that are enabled in config and therefore reserved => controlled by the ECM and tested with the mdhcommand.

*All the I259 channels are good 0v when off and 4.93v when on (using logic level trigger for coils with built in amplifier) when measured to gnd.

*All s259 channels seem good OFF .54V ON 11.63v

*All P259 show 0V all the time When measured to 12v

* Tried to check the injecter fets but I have never been able to comprehend that table look up system, I only used 2 and have 8 in place so if 2 are dead, I dont care, I have the other 6 free

** Read GenBoard/Manual/DigitalOut, GenBoard/Manual/DigitalOut/Table (ask there if you don't understand sg.) With h[0]=01 02 04 08 10 20 40 80 you get a 1-1 mapping,so mdh80/mdh00 touches injA, mdh90/mdh10 touches injB, and so on

*Tested wbo2, tested to ground mde 02 slowly but eventually gave me 4.93v on the FET pin closest to the ec36 connector, the other 2 FET pins were 0v. In relation to power, they were 11.67v when all said and done at the 2 furthest away from the ec36 and 1 shuts off with mde00, basically, that fet is ok and circuit working.

* We use multiple gnd5 pins. (good!)

* is it ok to use multiple gnd pins too or would that cause noise issues?

** multiple GND are good, it will NOT cause noise problems if the sensor GND (most importantly VR-) is connected near the EC26pin26 (not in the GND5 current path)

New P259 chip on order (2 actually, 1 for next time)

* 2xTPIC6A259DW chips should have been sent out from USA East Coast on 2006-02-03. However, it turned out that the chips only existed in the inventory database, not on the shelf in USA. We send the chips from Hungary on 2006-02-06.

**NO BIG RUSH Whenever they show is fine, if I really need to use the truck it is less than 10 minutes to convert back to the carb.
