Wideband Woes - Is it "better" to connect wideband directly to ECU?

[MAC]

Well with an endorsement like that I will give it a go.

I was looking at my ECU and it looks like I don't have a wire landed on pin B16. Does anyone have a connector they can sell me or is there a source for stuff like that?

your local gm dealer should have some on hand and should just give you one if you ask nicely (at least that worked the last few times i needed a spare).

there are a few different ones but i think GM# 12089660 is the one you want; don't quote me on that but at least gives you a talking point when you walk in there

The link below is for the pins (18 AWG) I use for making a new '7747 harness.

Maybe a GM dealer near you will have the same part # 12146448?

I have been usign autoprom inputs with great results, however, it's best to calibrate it first. Set your MTX-L to output steady voltage (can be done using Innovate PC software) and see what is the autoprom value. Measure across the range and calculate the equation to get accurate WB readings.

Thanks for that tip Dzida.
