Jester Chrome ECU for 91-93 "Pins" Thread

[Keyan]

I think it'd be a good idea to have a thread for those of us with the 91-93 Jester ECU that has been repinned.

This is what the connector looks like.

The stock 91-93 connectors plug into the (from the left) first, second and 4th connections. The 3rd connection is provided by Jester, and is only populated by a single yellow wire, which is Pin #51. This goes to the OBD1 port to allow for flashing.

Jester provides a few extra pins, and for a good reason. The 94+ computers have electronic fans, vent control, MAP sensor, etc etc. Greg provides what pins these are on the 99 ECUs, but on the 91-93 pinned Chrome ECUs, these pins are different. So this thread is to provide information to those who use this ecu for what the pins are used for.

So far I know of:

Pin #7 "Custom Pin 48" in the Chrome ROM
Pin #51 Flash wire (Yellow)
Pin #52 Radiator Fan HIGH
Pin #53 Radiator Fan LOW
Pin #71 NLTS
Pin #77 Flash wire (Red)



Questions I would like answered in this thread:
What pin is the "custom pin 35 output" on the jester ecu?
what pin is the pin93 for the wideband?
and pin 92 for the map sensor?
I'm sure there are more...


If people can answer this I will update the list.

Same question for the"custom pin 48"?
what about 67 for the clutch NLTS?

Pin 48 is the FPR solenoid on the 98/99 ECU. This will be pin 7 on your harness.

Pin 67 is the park/neutral switch (also called the inhibitor switch) on the 98/99 ECU. This is pin 71 on your harness.

I'm sorry I don't know how Adam setup the rest. :( There will be more add-ons for V2.1 as well. Using the secondary O2s to log fuel and oil pressure along with a couple extra inputs/outputs that are on the 98/99 ECU but not used in the car.

It's probably wise to make a list for the 94-97 PnP Clone ECUs as well.

:lol:

Man I feel stupid... I didn't know that was there.

Been too wrapped up in code the last week and a half...

Thanks Greg, I updated the list :)

If we can get Adam to take a look at this thread when he has time, it should really help get this list completed.

If no one wants to create a 94-97 thread, I can, but I have no way to verify what people tell me (since I own a 93)

Sorry it took so long to reply. I didn't see the thread until now. I updated the webiste with all the info you need.

I'm going to hook the WB02 to the PCM for logging. Chromed ECU | Getting Started (http://chromedecu.org/?page_id=759) says to wire it to pin 93. Where is pin 93 on the 94-97 ECU?

[Uniuno]

I didn't find this page: Chromed ECU | 94-97 US VR4 Plug and Play Flash Ecu Installation (http://chromedecu.org/?page_id=1567) yesterday. The equivalent for pin 93 (WB02 5V) on the 94-97 ECU is pin 77.

Does anyone know what size the male diagnostic port pins are and where to get extras for a OBD1? Does anyone have a set of red and yellow wires with pins they could measure for me??

Any help is welcomed!!!

UPDATE: The 090 2.3MM Male & female pins work like a charm (available from from JNZ tuning)
