1st gen ECU in 2nd gen - Page 4 - 3000GT/Stealth International Message Center

Finally after all the shit I ran into and a complete rebuild later, I have my TT ECU in my car. I can say a few things now.

1) The car runs ten times better than before. No more wasting gas.
2) Radiator fan does not work. For some reason it was working with the 93 ECU in there but not the 91.
3) Only one o2 is hooked up and no problems yet. No CEL, nothing.
4) I hotwired the datalogger port in the ECU. I tapped three wires and it works like a champ. (Always spring the extra cash for an OEM connector, much more convienient).

So far thats it. I just swapped out ECU's and it seems to be running fine. I'll splice my rear o2 sensor with the ECU so it thinks I have 2 sensors hooked up and see if anything is different.

I just posted a pic of the derale fan controller I am using on my Venting thread. Solves the fan problem for less than $40.-- And it's best to make a harness for the front O2- Your car will run better. I noticed a big differance in pearlryde's car. Oh, and running one O2 sensor won't throw a CEL in that year ( it's the same as my motor). But will hurt performance some.--Dee

Thanks for the update. So you hot wired the datalogger to the hybrid obd port? Is the diagram for the port in the manual? cause I couldnt find it.

Couldnt find that thread, but thanks for the info. The HKS one i was looking at was $180

Sorry, I deleted the thread- it had too many pics. Here is the one I have. And it works like a champ.

I have my battery relocated so that my fused power block up top- and the fan controller between it and the fuse box.
The wiring is really easy- it's adjustable from 160-240 degrees I think. I have mine set @ 190 degrees. I also have it wired so it keeps running after the key is off until the temp is below 190 in the radiator. It's the best mod I have done to my car that cost less that $100

Cool, i just ordered it.

Thanks for the tip, saved me a lot of money!

J-Groove · 06-04-2006, 10:24 PM

Heck yeah, that is a lot cheaper than all my other options I've been toying around with.

To wire up the Diagnostic port is easy. There are only three wires used to log. Take pink wire (pin 10) and splice it with pin 113 on the ECU (pink also). Then take yellow wire (pin 1) and splice it with pin 112 on ECU (yellow also). Then connect the ground to any ground. I chose the ECU ground since there are a couple of them. That was it, logs great.

Wiring up the o2 sensor is not that easy. I don't have any connector on my harness for it (as someone stated in another post). I just put a sensor in and spliced into the heater + and heater-. Then I ran the signal wire straight to the ECU. I will finish running the signal ground to the ECU tomorrow. Hopefully it functions right. Everything else seems to be just fine. I can say that the car runs ten times better with this ECU in, and I still only have one o2 on it.

Nireez · 06-10-2006, 08:59 AM

OK I have grounded the signal wire at the ECU where the second o2 wire is. I still get no reading. I have no idea on how to get this working other than to get an o2 simulator. Any extra input is greatly appreciated.

Wildarmz · 06-10-2006, 02:36 PM

For the front o2 housing, I already had a connector there by the alternator 94 Fed Spec. For the rear, I simply extended from the rear o2 housing to where the NA one comes out by the downpipe, then heat-wrapped and tie wrapped the wires out of the way.

Not sure whats going on with yours though, do you have the heater wires wired in correctly? Double check the pins and that the o2 sensor isnt faulty.
