No o2 reading ??
O2 gauge in megatune/tunerstudio is not Reading correctly, it probably explains the reason I couldnt set my wideband up correctly.
I've been through the trouble shooting section and checked all the solder joins but still no joy.
Anyone got any ideas?
Thanks

First, what O2 sensor are you using? You have to properly configure it with MT and TS. For MT when MT is open, go to configurator and select the appropiate wideband. In TS go under project settings and select the proper wideband.

I am the other guy helping along. This is the same car that was having all the trouble with the stack wideband. We have given up on that and got an LC-1 for it. That is now in the car and reads fine from the Gauge (the gauge in the car I mean) However still no 02 reading from the MS. Then we brought it inside and tried it on the stim and still no joy. Running base MSPNP firmware and maps (again just reloaded it all). When the 02 pot on the stim is turned we get no reaction in megatune (or tunerstudio).
I have removed my MS from my own car to compare and mine works fine in all these tests. We are both running the same setup (lc-1, na engine, ect) but his will not give an o2 reading. As far \s I can tell looking thru the MS wiring diagrams for the o2 circuit on the PCB there are only 3 resisters involved with this input. I have checked them closely and cant find a fault there and of course we have checked most of the board over comparing the 2 and all looks good.
Ideas?

In fact in the interest of clarity, when it is plugged into the stim or the car, it sits and about 11/1 afr with a very slight constant wiggle of the needle.
Also in both his and mine these are ver 3.0 PCB's with the full MSPNP software package installed. Built to the letter as per the braineak directions.

Hey thanks Matt for helping me out, i'm pretty lost!
So i've got the stim connected and powered up, i'm assuming I remove the processor to do the above test?
Where do i hook up the other end of the multimeter to? (the black cable)
thanks

Just had a play, i was getting a reading on the underside of the board but not through the processor, it seems the processor cradle wasn't soldered correctly, cleaned a few of the joins up and voila, i know get a reading in TS. I actually jumped so high i hit my head on our light in the lounge, finally it works.
Charger is being fitted tomorrow.
Really thankful for your help guys, i wouldn't have known where to start without you.
