Hi guys,

Can someone explain the difference between DWP and base duty cycle in more detail?

Background: For the longest time I had been on ISO 17-19 or so and it seems that recently the wastegate tuning has been focused on rattle fixes and not performance or economy. Upgrading to the BB flash and ISO 25/26 my fuel economy dropped from 23mpg to 15mpg. I finally found an ISO 25 setting of DWP 52 and base duty of 2.2 that brings me back up a bit on economy to around 20mpg, but its still not great. If I go to DWP 80 like I used to have I lose about 5mpg and if I go down to 38 or so again I lose 5mpg. The car isn't exactly smooth or snappy on boost response so I am thinking of going back to ISO 19 if I can't sort this out. Thoughts?

Make sure you're measuring economy tank to tank using the odometer. I would not be surprised if the DME was very inaccurate with the various flash tuning changes we make on that end. But as a general rule lower DWP (menu 10) will result in less tip in boost and better economy. ISO19 was pretty decent firmware also. I always tell people run whatever works best for them. Half the time when we change something to improve it for customer A we make it worse for customer B. Although, I'm pretty happy with 26.6 currently.

Instead of the SLD stand alone I'd invest in our back end flash, which has an SLD built in to it. You'll need the back end flash for the NLS anyway.

Cant really tell much of a difference from the previous version my car liked (23g) other than when i let off the throttle, it feels a bit more forceful...whereas in 23g, id let off the gas and it would feel smooth....now with 26_5 i let off the gas and abruptly the car slows down and jerks like the brakes have slightly been applied.

Just loving 26.5 FUD=20 with BMS Pump flash
Awesome responsiveness throughout throttle range with silky smooth gear changes on my MT. No rattle issues as stock turbos have recently been replaced. 10/12 menu settings are 90/25. My car is running better than ever. Once again, spectacular work Terry, BMS FTW!

Totally agree here. I am still on 25 for a good reason and it works great with AT race flash.

I didn't buy the SLD standalone I bought the wires for the JB4 along with the relay/wires for NLTS, are you saying they were not required and all I needed was the USB cable + BT cable for the backendflash?

Each car is different. Going too high on menu 12 may cause it to oscillate or shift a bit rougher at low throttle. Ultimately as close to 27 as you can get is probably ideal from a drivability perspective.

If menu 12 is too high the jerking is abundant. Past 35 you should feel some jerking. Not driver friendly.

If you want a generic rule of thumb menu 10 is for when boost is < 1psi and menu 12 is for when boost is > 1psi.

But does a higher setting on 12 also mean more closed, like it does on 10?

so to high menu 12 would cause wastegate to be to close to early causing jerky throttle.
