Now, my idea was that you could use this to plot your estimated power output and rig something up to record the O2 and MAP sensor readings coming into the ECU. How would you rig a recorder up to record voltage over a period of time (like 10-20 seconds)? I thought that it would be a real kick-*** tuning tool. BTW, can't do it ALDL, the baud rate is so slow it only updates once ever couple of seconds...not near quick enough. I was thinking that 100 datapoints on a 10 second run would be about right.

Sounds kind of like an AutoXray. It captures data at a 1 second rate & outputs it in a display readout form. A Diacom is PC based & will dump data to a file. The older ECMs had a slower baud rate, relative to the newer ECMs.
