Boost Issues

[ICER33]

basically i have an avcr installed adn it has been stuck on high boost for a few months

just got a tune and on the dyno it was reset and worked perfectly, on high and low boost and even with the controller switched off, BUT when i got it on the road it wouldnt set low boost and is still stuck on high boost

now my question is why would it read on the dyno that the controller is working on low boost, but on the road it is still on high boost!!!

this is tripping me out

cheers

Possibly something to do with when the car is underload... the Dyno has tractive effort etc but isn't a true measure of driving conditions under load. Hence why most tuners (well the ones I know anyways) will tune on the dyno then do a road tune for touchups.

As to why no idea! .... Is it actually saying low boost but still reaching hi boost - or it saying hi boost on the screen all the time? I would be enquiring with the people you took it too as it sounds that as soon as the car is underload its malfunctioning for whateva reason..... or possibly that the settings were not saved properly when it was on the dyno?

is the avc-r boost controll setting still turned on? because realistically, if it is, it should still control the boost going over teh specified level. and is the level of control high or low? ie. 1-5 or 0? did he also run learn gear on the avcr? is learn gear O or X?
