The only problem with the LC-1 is that you can log AFR, but only against time not RPM. With out being able to refrence RPM or boost you aren't going to know where your AFR needs work, only that it does. You can buy another module that will allow 4 additional inputs to be logged. If you are running an emanage, there is supposed to be a way to use the airflow #2 input to log the AFR. I'm going to try this, failing that I will buy the SSI-4 ($129) and call it a day.

Right now I have the analog outputs going to the autotune on my emanage and my autometer AFR gauge. I only set it up yesterday, but think it works pretty good. Did a quick log and aside from seeing that I could run a little more on the rich side. Shouldn't have changed the O2 sensor AND messed with my AFPR at the same time. I suspect the AFPR is the culprit. Back to the drawing board!

The LCD panel he is talking about is just a cheap panel voltmeter. http://www.mpja.com/productview.asp?product=14505+ME

dunno. I think the rx-7 AFM can be adapted to run on a 1.8. Not sure if it'll do good or not since the MAF is more ideal for flow.

You cannot run an RX-7 AFM on the '94+ cars...signals sent to the ECU are quite different.
