Toyota dizzy bench testing success!
Posted: Thu Apr 06, 2006 11:59 pm
Hello, Id like to thank everyone who has helped make the MS2 what it is today!
My MS2 is now reading RPM from a distributor from an EFI celica on the bench with a drill simulating RPM. It has two VR pickups, one 24 tooth wheel and a 4 tooth wheel. In the Toyota wiring these signals are labeled NE and G, respectively. I cut a trace on the stim and wired pin 24 to the G pickup and the common to the negative terminal of my battery (in the OEM wiring the VR common wire is connected straight to the ECU, why is that?).
I had to do alot of signal tracing until I figured out how the VR conditioning circuit worked. Then all I had to do was wind R52 & R56 all the way out.
My battery drill only provides about ~1200 RPM but its enough to make me smile! Car testing will begin soon on a 16v 4A-GE with a 4K-U distributor.
