tell them to clamp the pick up around the wires going into the ign module
it will get a signal , the 2.4's are the same way
they tried that and it was reading 3000 rpm's at idle

they need to adj the tach multiplier in the software there are like 4 pulses so they have to divide by 4=750rpm...we did this long ago on mine

its the pink wire on your icm thats your ignition voltage if its a dynojet they divide it by 4 and should get an accurate reading
