The boards are the same between all the firmware revisions, the only jumpers you need to worry about are the VR/HR setups, and it sounds like you have an ECU with a fried/shorted ignition driver that had the legs cut to prevent a hard short.
So that means I can't drive an ign. coil with this unit? This was done during manufacturing not a mod by an end user...newt said:The boards are the same between all the firmware revisions, the only jumpers you need to worry about are the VR/HR setups, and it sounds like you have an ECU with a fried/shorted ignition driver that had the legs cut to prevent a hard short.
Why do you think that? Your description fits exactly what a transistor looks like when its over-driven, overheated and shorted. then cut out.DDG said:So that means I can't drive an ign. coil with this unit?

Uhh, no, the transistor would not be burnt up and cut up during manufacture, it's from being driven too hard or an unfused harness/coil short.DDG said:So that means I can't drive an ign. coil with this unit?

Ok, once I removed the vacuum line I can get a much better view of it.... it looks fried....newt said:Uhh, no, the transistor would not be burnt up and cut up during manufacture, it's from being driven too hard or an unfused harness/coil short.DDG said:So that means I can't drive an ign. coil with this unit?

The board will either have pristine, new, clean, un-fried drivers, or small resistors in place of them to drive TTL coils.
Jarrid,TheArchitect said:Here is the story of your 1C box.
1) Someone over-dwelled ignition driver 1 and burned it up.
2) They decided to try and to the same to driver channel 2, but probably heard it pop before it went into nuclear meltdown and decided to cut the IGBT leads.
3) They decided to run an external TTL coilpack (and probably cooked that too).
As it stands, Ignition 1 (Q7) is setup for a single external TTL coil in a distributor application.
Q8 could possibly be replaced and it could drive a "dumb" single coil, or jumpered as is Q7 to run a TTL input waste spark 4 cyl coil.
Someone has not been kind to your ECU.

Thanks for the info... yeah...I guess you get what you pay for!!!
I have a complete crank pulley, trigger wheel and pickup, so i can use that along with a 5kt 1 window dist for timing and cam postion?
I have an 034 HO coil already installed, once I repair "Q8" I can drive the coil with that correct??
I also have a new 1C harness.
This ECU will replace the ancient "ECU32" I'm currently running on my 10V 2.6L with E85...
Am I forgetting anything?
PS. I'll need to swap out the 2.5bar Map for 1 bar (I have a spare)
This ecu came directly from Nate's old CQ turned Ed's CQ turned aorsinger's CQ. Between Ed and aorsinger, i pulled it from the car and didn't use it, in turn sold it to "DDG."TheArchitect said:Here is the story of your 1C box.

Makes sense now, I told Ed about the state of that hammered and recycled ECU, and it was included with the sale of the car, and driven for many many thousands of miles like that.PRA4WX said:This ecu came directly from Nate's old CQ turned Ed's CQ turned aorsinger's CQ.

The ECU was fully functional if I recall, as long as you were using a TTL style coil on IGN1. The complete lack of pad material means IGN1 will never again have an IGBT driver, don't recall the condition of IGN2's pad.
Okay, so excuse my ignorance here, but this means, functionally the ecu can be setup to work but has the limitation that the IGN1 driver is limited to one service (TTL coil, but not IGBT), but the IGN2 could be used to drive an IGBT coil?newt said:Makes sense now, I told Ed about the state of that hammered and recycled ECU, and it was included with the sale of the car, and driven for many many thousands of miles like that.PRA4WX said:This ecu came directly from Nate's old CQ turned Ed's CQ turned aorsinger's CQ.

Or he simply forgot, since the ECU was in service for years as it is now with no problems....DDG said:Uhhh ohhh....... I think Ed's busted!!!![]()
Do you guys have the ability to replace IGN2?
Let me know...
From now on this thread should be called "ECU-gate"!!!
I'm sure this is the case. Ed's a good guy i can/will vouch for as well.newt said:Or he simply forgot, since the ECU was in service for years as it is now with no problems....DDG said:Uhhh ohhh....... I think Ed's busted!!!![]()
