Silber fuel control box & Innovative A/F gauge wiring questions

[Merlin]

Hello,


We are in the process of tidying up the wiring on a second hand '12 Pro RMK 800 equipped with a Silber turbo package.............


After reviewing the turbo installation instructions & literature on the A/F ratio gauge we we're left with a couple of questions that we we're hoping to get answered:

1/ The yellow wire(0 - 5V analog output) on the Innovative A/F ratio gauge(MTX series) is connected to a tan(or brown) wire on the Silber fuel control box - Is this correct??? If so, why is it there??? The Silber instructions make no mention of this connection...............

2/ What is the purpose of the solenoid controlled valve in the boost signal line/hose that feeds the Silber fuel control box???


Any advice would be greatly appreciated.................


Thanks in advance,


Glen

the brownwire is not to be connected to anything. it was for the future when he was going to utilize the intake o2 sensor from the stock air box. he ended up having to go another route to make that function work. its just a coiencidence the afr has the same plug... i think?


for the boost line thats anyone elses guess? i can make a guess- maby the box cant handle full pressure and needs to be lowered with that box? maby? its a guess anyway, but it is how its set up so run it

Thanks for the reply,


So the brown wire is not supposed to be connected to anything but was designed to be connected to the factory TMAP in future applications???(I assume you mean TMAP instead of intake O2 sensor???) Either way, the installer had the A/F ratio gauge analog output connected to the tan wire on the fuel control box using a single terminal weather pack style connector - they must've connected them by mistake???


As for the solenoid we have no intention of eliminating it, just wondered what it's purpose is...........We also wondered about it being used for pressure control but it is simple 2 position, 3 way valve so it would appear to block the boost pressure from reaching the fuel contol box & vent the line feeding the box in one position & allow the boost to reach the fuel control box unimpeded in the other direction......................

From my understand of it the purpose of the siloniod is to relieve the pressure in the reference line when you let off the throttle so it quits adding fuel for boost. Like a bov for the reference line.

That makes perfect sense, thanks for the info.!

Can anyone confirm this is not to be connected.

Thanks

The brown wire is for nothing. It is for future development. You do not need to hook it to anything.

i just installed my innovate gauge. i left the yellow and brown alone, red to 12v supply. white and black to ground. i hooked the power and ground to the headlight harness. there's rubber plug in the harness and its dc power with inline fuse of 2 amps. i tested the gauge with 02 sensor and it only draws 1.6 amps so its safe to run that rubber plug. hope this helps

The Headlight is on the AC Power Side I believe.
