Ed, I'm trying to get the datalogger running...
A few more baby steps and some weird bugs today.
I checked the MAP sensor again and again got 1.62V with the car shut down. With the car idling, it gives 0.68V. It finally hit me that if 3bar = 5V, then ambient (1bar) should be 5/3V, or about 1.66. In other words, the sensor reading is okay. Unfortunately, by the time this sunk in, I had already ordered a new sensor. Oh, well.
I called EFI Technology and spoke to Mark about the problem with getting the Airbox Pressure scaling to "take." He had never seen an issue like this, and agreed that going back to the 7.1 editor might be a good approach. He emailed me a link to the software and I downloaded it. But when I tried to unzip it, there was an error message indicating that a required file was missing. On a whim, I tried one last idea to make the 8.1 editor play along. I extracted the config from the ECU back to the laptop. That (somehow) got the config file unstuck and I was able to set the right Airbox scale and offset. Air and Water Temp were already okay.
But, when I started the motor, while I got good numbers on those parameter, all other parameters were stuck on zero. A look at the config showed that all other scales were at zero. Fortunately, I was able to reset them all manually. Here is what I set:
Lambda Correction 1,2. 0.781/-100.0
Lambda 1,2,Setpoint. 0.005/0.600
Spark Advance. 0.250/ 0.000
Sync Position 1.000/0.000
Vanos Setpoint. 0.250/0.000
Duty 1,2. 0.391/0.000
Pedal Position. 0.500/0.000
Accel Rate 1.000/0.000
Cam 1,2. 0.250/0.000
ECU Temp. 1.000/-50.00
I think that covers at least everything I need.
With a walking, talking editor and maps in the ECU, I turned to data logging. I set up the logging table channels and frequencies without any trouble. I set the Enable parameters very low so I could log while idling. I idled the motor a while to test the logging.
Unfortunately, each time I try to download a session, the download will not begin. The progress bar appears, but that's it. The toolbar turns light gray, indicating work in progress, but eventually the cursor turns into an hourglass icon and that's as far as we get. The only way out is to close out the editor. No session file ever gets through.
Is there another configuration that I need to set up, or that may have gotten lost along the way?
Tomorrow, I'll try datalogging with the newer laptop and USB/serial cable and see what I can learn.
I'll also recalibrate the wideband sensor for a good long time, in free air.
Finally, I'm wondering if my injector calibration is correct. What should the settings be?
