Hey guys - I just finished working up my turbo brake - It's great!

The only thing that's NOT great is when I turn the key off it BUZZES LOUDLY.

Any ideas?

I'm in a low altitude area (at about 100 feet above sea level) .

Desired Boost levels EGR ON (Even though I've shut it off via programming)
0 MM3 - from 0 RPM until 1000 RPM at 15 LBS boost
0 MM3 - From 1000 RPM until 4800 RPM at 25 LBS boost
No other changes

Desired Boost Levels EGR OFF
0 MM3 - from 0 RPM until 1000 RPM at 15 LBS boost
0 MM3 - From 1000 RPM until 4800 RPM at 25 LBS boost
No other changes

Turbo Vane Position EGR On
0 MM3 - 1200 RPM - 4800 RPM 100%
No Other Changes

Turbo Vane Position EGR Off
0 MM3 - 1200 RPM - 4800 RPM 100%
No Other Changes

Turbo Vane Position Maximum Low Altitude (other altitude set up the same)
0 mm3 - 300 rpm until 3600 rpm 100%
5 mm3 - 300 rpm until 3600 rpm 100%

Turbo Vane Position Minimum
Not changed
(Although Earlier I had set 0mm3 300 rpm until 3600 rpm to 100%)


Now everytime i turn the key to off, in like 1 -3 seconds it starts buzzing.

Any ideas?

I do NOT have any additional hardware, the turbo brake is ALL Efilive program
related... the buzz is making me nuts, and I've switched tunes (which alleviated
it)...
