Boost Defuel after Overdrive Shift

Recommended Posts

Hey guys,

So I've been using a boost Defuel setting of 50psi. Works great. No matter what tune I run, boost ramps up quickly and sits about a needle width below 50 on my gauge, and 48psi on the quad. Beautiful.

 

Now that's where it stays until the 47re shifts from 3rd to OD. Canbus fuel must be clamped to a certain # in 3rd, and when OD takes over, rpms are much much lower (.69:1 instead of 1:1 gear ratio), so I've lost that much fuel. Boost drops significantly at this point. I haven't datalogged but I believe I'm losing more than 10 psi in overdrive.

 

The only option I have is to let off the go fast pedal and get back on it.

 

Any ideas?
