utec not reading correct boost

I have a utec and everything seems to be working fine but it will not read above 9psi in the logs. I'm running a AVCR and not the utec ABC. I have it set up the same way on my subie and it reads up to 26.3psi on the logs.
Any advice?

Two things, do you have the gm sensor hooked up, and also, is it hooked up to a vacuum source that isn't being restricted in some way?

no external GM map sensor, no boost reading... UTEC requires an external sensor to read boost.

yup, the does not have multibar map sensor, at least not the us evo. You have to use the dtec map sensor or wire up a gm 3bar.

gotcha, funny thing is I've tuned 4 maps on a dyno and never noticed till lately logging on the road. I was using the AVCR settings and the boost graph from the dyno to tune originaly. Guess you dont see what your not looking for. LOL
On the subies it just reads off the stock sensor.
thnks again.
