After i installed the commander it won't show my boost, and it is showing my tranny temp at 300. Why is this?

 

I'm not sure on the boost but the Tranny Temp sounds like a grounding issue. Where do you have the probe installed?

 

Right behind the battery on the driver side. Its in with the other grounded wires.

 

forau is asking about the temp probe it requires a ground on the pipe threads to work if you placed it in a cooler line you have no ground gust run a ground wire to the probe body, on boost did you tap the correct wire if not that next take the tap off and skin the wire and connect and tape, you do not have boost untill under load

 

I did hook up the temp probe into the tranny plug but i didn't have any wire to gound on the pipe. There was a single black wire that ran only about two feet and i hooked it up to a screw that has the other grounds hooked up to on the driver side behind the battery.

 

The Quad harness wouldn't have had a wire to ground. If it's installed in the test port on the side of the transmission you should be getting a reading. If it's installed in a cooler line that you purchased extra then you will not be getting a reading. In any case, try clamping a wire to the temp sender using a hose clamp and a piece of wire. Then connect that wire to the chassis. If the sender works, you should get a reading after driving and the Commander should give you a reading of 100° till the trans warms up.

 

Okay its a single black wire with a small circle clamp on the end of it. I thought i was suppose to ground that wire? I guess i wasn't suppose to, so where do i need to put that?

The tranny temp is showing from 299 to 300 degrees.

Also the boost will not work so whats wrong with that?

 

Anybody any help??? Im starting to get ******.

 

for the boost do u have the new harness that piggybacks the sensor or did u tap the wire?if you tapped the wire,double check to make sure you got the rite one,on mine there is 2 wires,i checked the sensor with a meter to get a voltage reading,the other is a ground,mine was green i think but yours may be diferent,like stated before you need to drive it to get a reading,i cant remeber if the camander has to have the boost sensor turned on to get a reading,you may want to go into it and check under sensors if boost needs to be turned on.

 

I tapped the MAP senser like the instructions said. Not sure if it was the right wire but i drove it to class and it showed 0 the whole way there. How do i turn the boost senser on?

 

maybe just for fun untap the wire and tap the other one,i think on the camander you push diplay and theres a setting that says sensors,its wheere u would turn on the sensors for fuel pres and tranny temp,also checkthat u have the camander set for your truck,its also in that location

 

RTFM :P
Sorry it had to be said.

 

I RTFM! It doesn't specify! Appreciate it

Page 14 on the PDF version of the manual specifies what you need to do with the MAP sensor and even has color pictures.

This is the same manual that comes in the package.

 

Okay got the boost working. I just had the tap on the wrong wire. Now what about the tranny temp? Which plug is it suppose to go in? The one towards the front of the truck on the passanger side or the one just back from that one?
