last night my deffi boost gauge started to over read by about .2 of a bar.

it has been fine up until now.

what do you think as caused it?

pipes are good.

checked it against my power fc commander, and avcr.

on idle the - figer is .2 higher as well


thanks

all defi's read about .2 bar up, not sure y its suddenly changed though

 

my car boost at 1.5 bar, and set the warnings just over 1.6 on them, and last night it was buzzing all the time when boosting it, but all the other gauges said it was 1.5, and deffie was at 1.7+

and on tick over the defi would be -.2**, and the other gauges -.4**

really strange why it has change.

 

Check the calibration against a known pressure. Its the only way to be sure.

 

think there is more chance of the defi reading wrong, anf the apexi avcr (boost controler), and the apexi power fc commander.

just not sure why.

mayb just a glich, and its got its brain out of gear.

 

Mines always over reads all the time.

 

is there a way of cleaning out the boost solioned incase it has got dirty?

 

been out for another test, and it is better than yesterday, but not 100% right.

got a couple of more ideas yet to try though

 

I take it you do have the pressure sender unit the correct way round (hole to the bottom)..?

 

yes hole at the bottom
