So what, maybe a bad Map sensor? Come do think of it, I haven't checked to see if it's reads 0psi when the car is on, but not running. Have to check that tonight when I get home from work.

Well sure enough. With the electronics on, but the engine off, the FTM reads -.6 -.7psi of boost, with both my gauge and my LM-1 datalogger reading 0psi. Before this I did have a DasMopar mapclamp, could that have caused some damage to the sensor? Should I go buy a 3 Bar Map sensor?

Did you try recalibrating the map sensor??
Do you live in a mountain area? Elevation could cause improper calibration i would think. Not sure if a map clamp can cause map damage. Guess John needs to chime in on this one.

well i tried to calibrate the sensors, but the loading bar gets stock ar 50% trying to calibrate, it hapends with the rpm, and tps calibration, i also tried the wideband and the same happened, anybody has the aem uego? is it the blue or the white wire off of it for the ftm blue wire?

I live about 10 minutes from the ocean in San Diego. Every other gauge i have that measures boost show's zero, and I don't believe you can recalibrate the Map sensor. There's no calibration for it.
well i bougth the pda usb/adapter cable my friend said i need a driver for it, thats why it may not be working where do i get the driver i can i download it ffrom somewhere?

Sure there is. Turn your key to the on position, but don't start your car. Hook up the FTM to your laptop and connect to it. Click calibrate sensors, go to calibrate map sensor, and follow all instructions. For the RPM's and throttle position you will need to follow the instructions provided. RPM's hold motor at 2,000 and click ok, TPS click once without foot on gas one with it floored. You must calibrate these sensors.

Well those calibrate the Map tuning device, not that Map sensor. All of those are spot on. My rpm's are withing about 50 of indicated, and the TPS sensor is good to go also.
Are you a stg 2 or stg 0/1. It could be that you have the set up on the wrong settings. When you log into the FTM do you see map 2 or 3? and what stage PCM are you?

This could be the problem, but not sure. Send me a pm with you address and I will send you another test map sensor to check it with. Then we can go from there. Please make sure that you put the details in the PM about what we were talking about in here, thanks.
I'm on 05 Stage 0, and the map sensor is set up for Stage 0/1
Ok then it all sounds good. I really dont get that bothered about the .6 to .7 difference but lets be sure and get it tested with the new (used) map sensor.

Well it is only .6-.7 at idle. But at full spike it's 3lbs off. If it was only half a pound, I wouldn't worry either, but three! That just seems like a little much to me. I checked all my joints again, and I'm using good silver solder. Who knows, thanks for the help John, this is why i will continue to buy your products.
Got it and we will get something figured out asap. I dont think its in the FTM but more of a problem with the sensor or possibly a bad ground. Please also check that the 12 vlt power supply is good all the time. I have seen a few that got hooked up to a 12vlt supply that changed over time or just went away after a while. Double check and I will get the sensor out to you tomorrow, thanks.
