[Thuppu]

AAN PnP Vems has a 4bar map. Should be ok for quite extreme setups

[Pedersn91]

okey, good, where in vems Adjust?

[rxl]

it does not work like that. you cant set boost from 1 bar to 2 and your tune is finished.

[LHD_Kid]

honestly, it doesn't sound like you should be trying to do this yourself.... I would suggest you get someone who knows VEMS to make adjustments for you...

[AndyP]

Wait, you mean you can't just go into the boost page and turn it up to 11??

[rxl]

if your building a bomb yeah

OEM MAP sensor is 416kPa, so you can setup boost in VEMS up to 3,16 bar boost (416kPa atmosphere). If it cuts at 2 bar there are probably some safety limits in your tune. If you send me log I can tell you.

so..... tuning IS a problem... good luck.

Check in the setup under safety where your boost cut is set. Most likely it's close to around 300kpa therefore once you try and 'ask' for more boost you are reaching your boost cut limiter. Raise that to 340+kpa, add a line of fuel+timing for that boost on the equivalent tables so that you can have values for these targets and then you can tune it

ok - just PM me
