Well I couldn't fix the PLX unit so I went out and got a new Innovate system. Picked up a LC-1 and two SSI-4 units. I got it all for under $300 new from a local shop. I also got a Moates O-Meter for a realtime display.
Anyhow, I plan to log the following signals:
LC-1- Native AFR
SSI-4 #1
channel 1-RPM
channel 2-Injector Duty Cycle
channel 3-Ignition Advance
channel 4-MPH
SSI-4 #2
channel 1-MAF
channel 2-TPS
channel 3-Intake Temp (ACT)
channel 4- external G-Sensor
I already had most of these signals run into neat ternimal blocks for my PLX but the Innovate stuff needs reference grounds for each signal.
For MAF,TPS,MPH, and ACT I used pin #6 on the EEC harness as my reference ground which I think will be fine, and their + signals of pins 50, 47, 3 and 25 respectively.
For RPM, Injector, Spark advance, I'm not sure what to use for reference grounds. For RPM, I'm going to run a wire from the stock cluster to the logger for the + signal, unless there is somewhere I can tap into the computer which is closer. Regardless, what should I use for the reference ground for RPM?
For injector, I tapped the #6 injector at pin # 12. But I'm not sure what to use for the ground reference.
The same goes for the crank sensor, I used pin# 56 for the + signal, but I'm not sure what to use for the reference....pin #16??
I'd attatched the wiring diagram for a 92 SC. http://econtent.autozone.com:24991/...0c152/80/06/bb/d6//large/0900c1528006bbd6.gif
Any help with this would be great.
