N54 HPFP oscillation over 22psi

[jakeg]

Hey guys,

My hpfp is dropping in pressure to ~1500psi under WOT, and then recovers to 2500psi and dips again.

I added 40% duty to the port injectors on the reflex to compensate but the STFTs max out at 34%.

Im thinking about adding another 10% to the duty cycle until the STFTs stabilize.

Any thoughts?

I thought that anything over 1500psi was good to go.

Oscillation to your HPFP correlates to your boost curve. Fix that, than and it should level out the HPFP.

Cant see that the HPFP Oscillation would cause the boost to go crazy.

Noticed that the fittings on the wastegate were slightly loose and tightened those up.
I switched over to a reflex controlled setup.
Now I'm fighting the reflex not outputting a signal to the MAC.

You can set MHD up to output the wgdc to the Reflex over CAN then just have Reflex pass that out via one of the aux outputs.

Your tuner should be able to set that up for you and get the boost stable.

yeah ken sent me over the files. Its not hitting target and I've come to the realization that it needs more wgdc.
