Hi guys, I don't know if this is a problem or is it normal but everytime I unplug the Predator tuner from my car I have problems starting the engine. My other problem is I'm having problem starting the engine when the engine is cold. It sounds like it's not going to start. What can this two problems be???

It certainly doesn't sound normal. I have the XCal2 tuner and do not experience this problem. Car starts fine in cold (although ~30 degree is coldest its been in). Have you isolated the problem specifically to the Predator - i.e. does it start normal other times and you only have the issue after using and unplugging Predator. Is it possibly a battery issue (trouble in cold) - does it spin the motor but it just doesn't catch or is it slow to spin the motor?

Good luck.

I'm talking about two different problems one is with the tuner and the other one is everyday when I start the engine when it is cold. Other than that the whole day the car starts fine.

Maybe it's fuel pressure? Do you hear the fuel pump cycle at key on first thing?
