Alright, I am installing my m-300 in my 93 del sol, P06 obd1. there are those white and black wires coming from the controller, Wher exactly do they need to go? I saw another topic where someone said use a three way switch so you could toggle the ecu from seing the wideband/narrowband sensors, I was under te impression that the ecu needed to see a narrowband signal no matter what. I am using ECU control to datalog if it makes a difference, any help would be appreciated.

Reading a good how to on Crome, and reading installation instructions from plxdevices.com, own you.

 

the instalation instructions they sent blow ***, not very helpfull but i'll keep looking

 

Power, ground, signal out, ownage.

 

Thats my question where exactly does the "signal out" get wired "in"?

 

Ah. Why didn't you just say so?? :P

Disconnect the stock O2 input wire entirely (or unplug/remove stock O2; if you have WB and stocker in parallel things get fucked) and slip the white 0-5v output in place of it @ pin D14. Lodge ECU in open loop/debug mode and log to your heart's content.

The grey wire is 0-1v narrowband simulation, and you can switcheroo that right over.

 

Can I just leave them both connected, and put in a swtich to toggle back and forth, I've heard its not good to have the wideband running all the time, and doesnt the ecu still need a narrowband imput or is that why you "lodge ECU in open loop/debug mode"? This is just getting confusing but thank you for your help it is much appreciated, i'll try it out.

EDIT: Do I just yank out the wire going into pin d14 and stick this one in there, or do i cut it and splice it? How do you guys do it? a pic would be nice. thanks

 

Wideband sensors wear out... about as fast as stock ones, really, but since it's *supposed* to be a calibrated instrument with good response time people get all ---- about them. Having yours mounted in car so *you* can monitor it, and replacing the senor for $50 every 10-20K miles... sound like it's worth it?

Like I said... "switcheroo"

 

How and where do you setup the switch, does anyone have any ideas or pics?

 

Either grey wire has continuity with D14, or the white wire does. Golly.
