1 bar. any suggestions guys

Hi Aki,

 

You sure you've got it set up right? Don't forget it's the duty cycle that controls the amount of boost - not the boost setting.

 

The idea is that you set the duty cycle to give you your target boost. Boot it a couple of times and it starts self learning - then you can adjust the boost level to what you want and the duty cycle will be adjusted automatically to give you your desired boost (in theory!)......

 

You have two channels - A and B (and off), you still using the same one??

 

Other than that - what Duffman says....

 

BTW - anyone have any idea why my boost level creeps ever higher when in self learning mode on the AVC-R?? Starts off bang on 0.9 bar and 200 miles later it's hitting 1.0 (!?) Think I'm gonna turn self learn off and set it up manually - much more reliable....

 

Cheers!!

Oh - BTW, Duty cycle between about 37 - 40 gives me 0.9 bar...

I know on the Blitz controllers auto leanr mode doesn't work on a Z because of the twin turbo's. You have to set it to manual.

Maybe the Apexi is the same?

thanks for the advice guys on the boost controller guys, but now i have a bigger problem.

 

whilst driving the car last night i noticed a strange scraping noise from underneath the car, it was the plug from the starter motor. when i fitted the starter motor i didnt bother to slide the plug on the metal bracket to which it was attched originaly, i used a cable tie instead and it must have came loose whilst i was driving.

 

anyway i have now slid it back on the bracket and tidied the wires up but now the car wont start. frown.gif

 

btw the battery was connected whilst i did this. any ideas guys
