update (wicked long) Posted by Andy [Email] (#759) [Profile/Gallery] (more from Andy) on Sun, 11 Jul 2004 08:02:26 In Reply to: thanks andy, jak [Profile/Gallery] , Thu, 8 Jul 2004 18:07:46 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Well, most of the problems I had were tied "litterally" to the O2 sensor.
I found out through TSN that the outer shield of the o2 sensor can't touch the innner wire. When I installed my A/F meter, I wired the o2,a/f meter and both the shielding wire and the signal wire wrapped in as well. I should have figured it was a shield when I looked at it. "Duh".
So it looks as though the o2 sensor wasn't working at all, hence the a/f meter was not either.
Now get this,I was trying to use a 300 ohm resistor and it was not idling at all, up down, up down. I went down to 200 with a variable 25 pot and still nothing. Then I said screw it and tried no resistor., Bang, no CEL perfect idle. So went back, for haha's and put the 25 in and it still ran great. So like it has been said before, there is no magic resistor #. I still have to take it out and fine tune it, but most of the headache has been resolved.
One last thing, I am using a 948 ecu. Are the maps different or is it most likely on the rich side. It seems pretty clean running.
Here is a cool site for anyone looking for a a wideband setup to get accurate a/f readings.

I plan on getting the M-300 and the wideband converter.
Allright, that's it. C-ya
