Default 6466 single turbo logs+ question. - 08-14-2019, 03:48 PM

I just installed a 6466 precision turbo on my n54. I got the kit used, so I'm not sure on the waste gate spring psi.

Map1 shows about 16psi. When I switched to map 2, boost spiked at ~17 psi. So, assuming everything was going as it should, I switched to map 3. But, boost will not go above~18 psi.

With the car off, I can hear the Mac solenoid clicking then the gas pedal is 40%-60%. The solenoid doesn't click with the pedal "floored". Any ideas or advice? Thanks for your time.

Which flash did you load?

Can I see a map 3 log?

Map 3 with dwp and db adjusted.

Side note, I've done the Mac solenoid test suggested by y Terry on a YouTube video I found. Car ignition on but not started, Mac solenoid clicks at part throttle but not at WOT.

Maybe it's just in my head but the car feels quicker on the part throttle range where to the solenoid clicks, than it does on WOT.

Appreciate the help with trouble shooting.

Let's try bumping your FF up- lets try settting that at 80-100, and let's see if boost goes up / you hit target.

What springs are you using in the WG?

With FF set to 100, I was able to pretty much reach Target of 20psi on map3.

I switched to map4 to see if there new FF setting would let me reach that target psi also. Unfortunately no. I'm hitting ~21 psi with a target of 23psi.

Attached are CSV files for maps 3&4.

Bump FF up to say 110 for map 4- keep an eye on fueling.

That adjustment got me up to 22.6psi in map 4. But my high pressure fuel pump dipped to 9 so I think I'll step back to map 3. Thanks again for all of your help!

I attached a map 4 log.

Yeah- it looks like your biggest limit now is fueling

If you want help dialing in map 3- let me know, but it seems like you have a pretty solid handle on it.

I'm definitely open to any suggestions you have for map 3.
