remote start on 2011 dodge challenger

Im still having the same problem. Today I hooked up the tach wire from the remote starter to the fuel injector wire still does not work. It says " low voltage" on my color lcd after doing all the step to setup the remote start. I have the brain set to manual mode and already did the learn tach. what could be the problem? Im using the db-all bypass d2d kook up.

still having issues with the remote start not working. could the tach threshold jumper cause this issues Im continue to have with the remote start? still get a "low voltage" on my 2 way screen.

Did you try changing the tach threshold jumper yet? It sounds to me like that is probably your problem...Kenny

I tried this morning programing the system again, still same error " low voltage" I search the options on my bit writter to see if there is an option for tach threshold, found nothing. I looked at my python 592 brain to see if there is a jumper anywhere on there, found nothing but the jumpers for the d2d and w2w jumper when using bypass. im lost with this, where is the jumper for tach threshold? it crazy, because when the car seems like it going to turn over the engine, but stops. it try to start the car 3 times and then says "low voltage" on my 2way remote. the parking lights flashes 7 times.

the tach threshold jumper is usually on the side of the brain on the pythons. Its a small black connector. There should be one for parking light polarity and one for tach threshold... Edit: I stand corrected. It is normally on the side of the brain, but looking at the install guide online it doens't appear to be there any longer. I'll keep looking and see what I can find.Kenny

Is it a physical location on the brain, or something i have to program using the bit writter?

On the older units it was similar to the D2D jumper, but looking at the diagram online, it looks like they got rid of it. I can't seem to find out how to change it on that unit.Kenny

When you learned the tach, did it give you the confirmation that the tach signal was learned? Try learning it again but this time way 5-10 seconds after starting it to tell it to learn. That will allow the engine to "level out" and give a more accurate tach signal.Kenny

yes the brain made clicking sound to confirm.

could the bypass I'm using cause issues with the car starting? (db-all xpresskit)
