trigger wheel sensor
Posted: Tue Mar 25, 2014 7:20 pm
I am running 2.905 code and am triggering fuel from the tach output of an msd ignition powered from my gm computer. This all runs well and the tach output is 12 volt square wave. I need to keep the gm computer to run my 4l80e transmission so need to leave the distributor vr output intact. I would like to switch to MS ignition control so another input is needed. My thought is a crank trigger wheel and the hall effect sensor from DIY should work without any changes to the MS other than setting up the trigger wheel settings. Yes/No? I tried sharing the vr output of the distributor but that didn't seem to work. I thinking 12 volts to the sensor should give a 12 volt square wave output the same as I have now.
