4AGE Distributor VR sensor compability

....shouldn't you be triggering on IGT?

gearb0x - doesn't it depend on the 4AGE dizzy. the earlys were the 24 / 4 and the laters (ae92) were 24 /1

both will have two pickups - : more http://www.autoshop101.com/forms/h23.pdf

btw, the Ne signal is produced according to the 4 tooth or the 24 tooth? the ignitor i am using now is not from VAST ignition. all it does is fire the coil when ever a tooth is passed thru the VR sensor. anyway, i will try to swap the signal fetch to the MS2 by using Ne wire instead of Igf wire and see how things goes.

Depends on the 4AGE. The AFM Bigport 4AGE should have 4 teeth on the NE wheel and 1 tooth on the G+ wheel. The Smallport & 20V's should have 24 teeth on the NE wheel and 4 teeth on the G+ wheel (I could be wrong about this last bit)

i am using "Igf" wire to feed the RPM signal from the toyota ignitor into the MS2 and the MS2 send signal to the negative side of the ignition coil thru "IGT" wire. that is how i connect it previously but since i still cannot start the car with MS2 takes control of the ignition, so i disconnect the "Igt" and let the toyota ignitor do the job.

trace the 2 wires from the 4 point vr sensor and feed in into the ms2 vr circuit and use the vb921/bip to fire the ignition coil, you dun need to make use of another external ignitor to control ignition. If you need a working msq I've a copy I can share but you'd need to fine tune for your application.

guys.. i managed to get the car started with both fuel and ignition control today.. which means there is nothing wrong with the wiring/connection. but i still feels like the RPM is not quite there.. the original digital RPM on the dash is dead so i'll connect a external RPM meter and see if it match the RPM in the megatune or not. when i check the ignition timing using a timing gun, i hardly notice there is extra spark event due to the double RPM.
