Got off my butt and decided to wire up the data logger. Its a LM-1 with an RPM converter.
I got six values going.
I got everything wired up including getting the wideband out of the neon.
The whole thing tuned into a disaster.
The O2 seems to have been working well.
I started by calibrating the RPMs I got it to read right by setting 5Volts to 3500 and that seems to display the correct rpms on the computer. Then I moved to the MAP sensor. I was unable to calibrate this right, no matter what I did I could not get it to match in PSI. So I gave up on it.
I left TPS in Volts and MAF in Volts. I guess I could turn them into 100% values 0-5V=0-100% but I left them like that,
Then the most important to me right now was the ACT sensor. I calibrated that according to the chart thats floating around here. And it seems to work well.
I went for a ride and the 02 sensor crapped out, Started reading bogus numbers. Then after the runs I noticed I never went past 3500 with the calibration on the RPMS so it pegs 3500 and doesnt really know what Rpms the car is it.
The runs was a 3rd gear pull and shifting into fourth and running that gear out. Then I stopped.
Bottom line is ACT temps never went past 130F if my calibration is right.
The weather is cold at. 54F So I dont think I will be able to find the problem until the weather gets hotter.
Ill try again tomorow and see if I can at least get the RPMS right.
