In dash. I was going to mount it in the glove box but I did not want the wires moving around causing problems when I open it. Under dash might get kicked or hit by passengers.

That's pretty clean psuedo!

I thought about hiding it back there on tranny tunnel, and it never crossed my mind to go flush like that.

Please don't copy this method without giving me credit:




Believe it or not the only problem I've had so far is accidentally shorting two pins on the header on the MS2 daughterboard when I covered it with the carpet. The car ran fine unless I loaded megatune, then it immediately died. That caused some head-scratching.

Mine is sitting on top of the sound deadening right beside the stock ECU under the aluminum cover. Routed the serial cable under the carpet and it comes out of a hole under the passenger seat.

Mines mounted in the passenger footwell on the tranny tunnel. This is the only pic I have of it.

yeah just for fun i tried to mount it 'stacked' as shown in one of the pcitures but there's no way that's going to fit for me :(

I have a wiring / electrical question.. i made a 'quick disconnect' for my wbo2 out of a 1/8" stereo headphone extension cable, 8ft long.

Once i wired all that up, i had to adjust my lambdasensors file so that the gauge and megatune would agree again.. prior to that, it was 100% accurate.. Today a friend came over and re-soldered a couple of joints in case i screwed something up, but that didn't make it go back to normal.

Would the length of the wire affect the base voltage? Would i be asking for the same kind of issues on all the other inputs if i extend hte length of the DB37 harness?

Is that stereo headphone extension just really shitty wire or something??

Fixed my short yesterday, but not the fans. :(

This is just the analog output line between the WBO2 box and the MS, right? IOW, the WBO2 sensor itself is not riding this line? Is power for the WBO2 also passing through this cable?

For the analog signal, it shouldn't make a difference. The current passing through the analog output is laughably small, and assuming you tied the shield to ground, I wouldn't expect it to be picking up any noise.

Now if you're trying to pass power through the cable, or you're using it as the primary ground, then I can see some issues. Those headphone cables are typically made from astoundingly thin wire, and you'd see some voltage drop across it if you're trying to pass any meaningful amount of current.

so what you're saying is i shouldn't have used that wire to run the power

That's the one thing i didn't do, is test the voltage once it's all hooked up..

Also, i think that this issue is affecting MLV too right?? Because megatune uses the lambdasensors file to get the formula to convert volts to afr, but megatune has an actual table, so if i changeed the lambdasensors, the table remains unaffected and therefore my MLV AFRs are all going to be off... i guess i'm goign to go disconnect the extension when i get home tonight.

Thanks for the label

You know I never take anything you say seriously right? I actually can't stand r&b or rap, live on agricultural land, and I can't stand those w/ the gangster lean while "driving". The wheel cover was just something I threw on there for the fun of it, but w/e I'm going to keep it on there now in spite of your e-thug status because you know me so well without even meeting me in person. What a reputation you've applied to yourself

You could always move it to underneath the radio where the cubby hole would be w/ a flat piece of lexan

or anywhere there's a flat surface with a void behind it to mount the usb port...


If you notice my USB cable, I did have to perform surgery on it to make it male/male, I'm gay like that.

Damn, I should have read these threads first.. Ended up drilling into the floor to mount mine next to the stock ECU. I wonder if I should use some sort of compound to inhibit rust. ****.
