Tack Does Not Work

[Pushit2.0]

Well I finaly got my 90 talon running, but the tack does not work. The AFC reads rpm fine but no tack. It has a stock ECU with a MAFT+AFC stock coil pack and pre-ignition, whick came off a running car, but I dont know if there tack worked. Just wondering in someone else had this happen and what they did, thanks.

I wonder if the MAFT/AFC is sucking up too much current on the tach signal. I have had problems on other cars after installing stuff like AFCs, AVCRs, nitrous window switches, etc with the stock tach going all goofy. The 90s are a bit different then the 91-99 as far as ignition and tach signal go, for example you need to buy a tach adapter for a 90 if you want to run an MSD DIS-2 ignition box.

I know whats wrong with it, John. There is a little transistor thing that you need that I have and forgot about it. I'm pretty sure I have it sitting in my garage.

I will pick it up when I drop off your tranny. When is a good time? Thanks
