[Gmecm] Wide band 02 sensors

[Garrett Herning]

Hi,

I have one of the Innovative controllers on my 95 pickup right now (PCM 
16197427). I had bought a couple sensors a while back in anticipation of the 
PWC the guys from MegaSquirt were working on, but couldnt wait. Was very 
easy to hook up, I actually spliced to a plug that as off an old 02 sensor, 
so the normal power for the narrow band feeds the controller and the 
simulated signal goes right to the ECM. Put about 5000 miles on it so far 
and it works fine. You can vary the AF switchpoint to whatever you want 
(which is why I installed it as I am working with modified heads that should 
allow me to run leaner). You can also vary how quick the response time is 
and how fast it switches. I've been chasing an ignition problem (seems I may 
have had a bad plug and/or a small vac leak) so I haven't gotten to really 
play with the settings. I do notice that I can feel the computer try and 
hover around "stoich" on moderate accels, so I think I need to adjust some 
of the settings to get the simulated output to act more like a normal o2. 
For the price you cant beat it. Comes very well packaged, good documentation 
and is robust. My controller is zip tied onto a crossmember by the trans. I 
am in the midst of a dyno project right now and wil be buying one for AF 
monitoring on there. Hope this helps.
