I installed my PLX wideband today using the ECT2 wire which I cut and crimped the wire out of the ecu to my analog wire out of my wideband unit. Then I tapped the radio wire for the power supply to the wideband unit. Then I went back in flashpro and enabled the ECT2 sensor. Now I have a check engine light stating ECT2 voltage to high.

 

I believe you have to disable the ect2 sensor and then go into the wideband or lambda tables and enable the wideband input as ect2.

 

So I am to leave ECT2 dissabled in the misc section.

 

When you do make sure you warm your car up real good otherwise it will throw a CEL and register as coolant not reaching desired temp. Just make sure you have at least 4 bars before you go driving and full 8 bars before you rev it past 4K.

 

Yes leave it disabled in misc section. Then select ect2 as your wideband input

 

I was able to get it working now. But the wideband is reading about a point leaner than my factory. I do know that you are also to ground the wibeband to the point of were the ecu is grounded and I do not know were that is. If you know were that is can you let me know or if you found a spot that works good for you as well.

 

It's the ground on the rear of the engine, near the firewall.

 

How the hell do you get to that with out dropping the trans or pulling the motor.
