However disconnecting the vacume redirects what ever the ecu deems nessasary all through the cooler. Which has a greater resistance than normal and a lot cooler air temp. Hence my noticeable increase in power. However I'm still pouring soot and nasties into my engine. So have now refitted the blanking plate with 8mm hole and leaving the vacume off as this has a greater resistance path and should leave less nasties entering the engine until the electronic full off becomes available . Hopefully will still have no fault codes come up with this setup.

It is available! As stated on a post from Tony on the previous page.

1. Working well and i have no function of EGR as observed on the scan-gauge
2. First drive last night, A bit peeved as i note a boost reduction of aprox 2-3 psi and boost seems to taper off quicker. I will go for a test later today and confirm if this is the case. Honestly im not sure if i feel any reduction in performance though, If there was no gauge installed you wouldn't know.
I'm going to investigate further and also Analise the unit with the multi meter later today.
7ohm resistor soldered in to the white wire from the air flow sensor

Again proven here no dispute as I've provided the hard evidence. I could achieve the same result as done on my ML with a resistor from Jaycar. Sure not as nice as the nice patch lead but same result.
I'm not willing to put up with a 4psi boost reduction for the sake of a non limp home occasional light I can clear. My EGR is fully plate blocked.

The cable was tested from pin to pin
Pin 1 - Straight through
Pin 2 - Straight through
Pin 3 - Straight through
Pin 4,5 - Connected together at the loom end with a 14.99k resistor
Pin 4 at sensor end - Not Connected
Pin 5 at Sensor end - Not Connected
The cable does its task correctly of electronically disabling the EGR function as can be observed on my scan gauge.
The disappointing road test:
No cable installed - 60-80kmh full throttle flat road - Initial spike 26-27psi boost tapering to a solid 24psi holding.
Cable installed - 60-80kmh full throttle flat road - Initial spike 23 psi boost settling at 19-20psi max.
A loss of 4psi and I can feel it.
