Re-program tach?

0 votes
I wired up an Evo-all to my '05 Lexus GX470 with a Viper alarm/remote start system. It had been working perfectly find for the past few months until I tried remote starting and the remote FOB ran out of battery right when I pressed the remote start button. Now when I try to remote start, the vehicle will start for 1-2 seconds, shuts off, and attempt to keep restarting over and over again.

I spoke with Fortin tech support and they told me to re-program the tach. I asked if it was the same as re-programming it all over again from the start but the tech support just kept repeating "re-program the tach." Based on the install manual I used from your website, the only "programming" I needed to do was the bypass. How do I just program the tach?

Tach programming is in your Viper unit, you should contact Viper to know the exact tach reprogramming procedure.
