Stock tach and DIS
Hello,
Does the stock tach require a HV kickback pulse?
I'm seeing some strange fluxuations with the DIS box, and I'm not sure if the factory tach needs a HV kickback or if it's dying.

Re: Stock tach and DIS
I bought a BTAC2 v00 tach adapter, which is similar to MSD 8920. It provides the appropriate signal for the factory tach.
I suspect as more and more people convert to full aftermarket ECUs, DIS swaps, etc this info may be helpful.
