I just installed my UTEC in my 05 EVO. For some reason I am seeing about 23 psi at idle. I just reflashed with 1.7 and have not changed anything.

I also tried changing the boost display from atmospheric to gauge but that just made it go to -.7 psi, even under boost it stayed at -.7 psi.

If it is of any importance i dont have the abc installed.

What is going on?

Find Attach File of the log i did so you can see what i mean

 

If you don't have the map sensor installed, you're fine. That's normal. I'm betting you don't have the map sensor so just ignore it.

 

i dont belive so thats what i was telling my friend maybe need a map sensor. but now what does that map sensor look like and go. and where can i buy one. if can help would be great.

 

YOu'd know it if you had it, since you would have specifically had to order it and hook it up.. -23psi is normal if you don't have it installed.. its the 0v point for the calibration settings in the UTEC..

 

ok is there anyway i can have where read the voltage to see what boost im making. i know i have a boost gauge but for tuning resones. and also im waiting for the new map sensor to come out. you know when that will be able to get. i dont want to spend 120$ today and then like in 3weeks the new one out. becasue i would then sell it for like 50$ if that. let me know thanks for all the help guys keep it coming.

 

Don't worry about it for the time being, just wait for the sensor you want if thats the case.
