Then, go to slower speed CANbus if you need. FUD bit 7 = 1 (FUD = 128).

On PWG the BEF has nothing to do with boost control or boost targeting, unless the DME BT is set really wrong, or throttle not mapped properly. The JB4 settings govern that and those depend on the...

That works too, unplugging just takes a minute. But if times don't improve we may let you borrow a jb4 that has more advanced logging so we can see why.

0-60 is not a great way to evaluate performance since it's heavily traction dependent. Try some 1/4 mile runs on map0 (JB1 disabled) and map1 to compare. Also, you may need more octane if the fuel...

You're limited to around 2.5x over the flash target for engine safety. See how this duty bias curve does. Stock turbos are needing a lot less dutycycel down low and a lot more up top.

My guess is DME is sensing knock and demanding a richer air/fuel ratio to suppress it, which is taxing the high pressure fuel pump.

Yes I want everyone who loads the BEF to enable bit6. And when I program JB4 maps I'll have it read that spot to determine if the vehicle is equipped with a BEF.

150. Could be some sort of bug also as FF is above PWM, but boost is below target. So that is strange. Let's see how pidgain = 25 looks. I'll double check the code to see if I can find any...

Trans temp is removed for the time being, we'll bring it back later.

Your boost is no where near target. PID gain should be 25, you set it to 10. And raise FF to 120. And keep raising it until...

Your AFR seems normal in your log for the stock flash. If you want to adjust the AFR load up our back end flash map.

Lets see some logs with the new high speed logging firmware. Also set FUD = 0 to return to normal speed CANbus logging and evaluate that. :)

Thanks,

In lower gears you also have a shorter time for boost to build up. So sometimes you just won't get up to target. Other times the DME limits boost for traction or other purposes.
