python 991 remote starts then dies

HI, i just finished installing a python 991 (the new one with 18 pin H2 harness) in my 07 tundra and when i remote start it starts then dies right away. Seems like its not learning the tach properly. When i have it in virtual tach mode it gives off a shutdown code that says low battery. My battery is good. If i switch to tach learn mode it gives off a shutdown code stating no or low rpm. I verified the tach wire is correct . picked it up at the obd2 port and is shows 5-8v ac. I thought i might need to adjust the tach threhold but they eliminated the jumper on this unit. Would greatly apreciate some help. Thanks, Cainonnoob

With a tach issue it would run for 15 seconds. Sounds to me more like a by-pass issue. Is there a factory immobiliser on this vehicle?* If so have you installed a by-pass? *I haven't a clue, only ever see them on TV shows.

Yes i have an immobilizer bypass module. Its an xk05. Was supposs to be programmed correctly. Read somewhere that if it shoots a shutdown code it is not a bypass issue? I can say that if i try to start the truck with a non chip key it just cranks forever and doesnt fire at all. Does the same if i unplig the bypassnoob

Aren't there two starter wires on that vehicle?

Forget my last post! Have you taken your tach from the white wire at pin 9 on the OBDII data/diagnostic socket?

Yes sir i did. Even tested it with a mm and got 5-7 v acnoob

What happens if you start the vehicle with the key and then enter "pit stop" mode and remove the key? Does it continue to run or shut down? If it runs the problem is factory security related. If it shuts down it is a tach issue. I would expect a remote start to display a low/no tach issue if the OEM ECU is shutting the motor off because it thinks it is being stolen.Kevin Pierson

It stayed running in pit stop mode. I wonder if the ebay guy didnt flash my xk05 right. My wiring matches the diagram i havenoob

does your key have a "G" stamped on it near the base?
