I'll try hooking the scanner to the laptop, but I'm telling you in advance, just don't think it will work directly. You will need to modify the input circuit of the unit, so the rpm triggers. To do that, you will need to play with both the resistance and condenser values. So you will need to know a bit about elctronics. Unmodified, it WON'T work. math

Having adjustable resistance at WOT and any rpm is easy enough. I already have that although the pot I have is very inaccurate and changes value with vibration. What I am really interested in is the RPM sensing circuit.

I try and built a few of them and was never able to get them to work. What I didn't know at that time is that our Bosch ignition system is very noisy. I realized that after installing aftermarket EFI system, and did have a lot of problem to get the rpm signal clear without noise. Had to use extra condenser, diodes, ... But what I did before for fuel enrichment device, is just add a relay wires to the WOT switch. Itjust changed the coolant value when the relay was activated, could be easy adjustable if you want.

The resistor should go from pin 30 to 87a. Rich Blake ---------- Original Message ---------------------------------- From: "Oleg M.
