I know that Innovate has other products that have better logging capabilities and that there are much better products out there for logging but I have the MTX-L. It came with LogWorks3 and I figured I would try to log whatever I can. It has two inputs for logging 5v signals. I just want RPM and Boost to go along with the AFR. Is there a way to get a 5v signal from the DME for RMP? What about boost? Pin 2 on the KLR is a timing valve signal and pin 5 is "Vacuum pipe pressure signal." The DME has an "RPM signal" on pin 27 and some kind of tach signal at pin 21. Anybody know if these are 0-5v signals?
