I just installed the Innovate Wideband O2, 3844 MTX-L.

At idle it reads around 14.5. At WOT is reads 16.5 to 17.5.


At those numbers. I figure the pistons would be melting.

I have had the car about two years and have put about 500 miles on it. Occasionally at WOT, once into it, the engine sometimes seems to stutter a little. Maybe that was pinging, I don't know. Then I back off.

I always run 93 octane w/ half a bottle of 104 octane booster.

I have full exhaust and put the O2 sensor in the mid pipe before the X, no cats.

I believe the timing is around 10*, based on what the previous owner indicated. He said he kept it running pretty fat for safety. I don't have a fuel gauge to check.

The black & white wires are on a good ground. The power wire is fed directly into a 15 amp fuse.

The super charger currently has a 6 lbs. pulley on it.

Can I really be that lean? Does anyone have any suggestions?

Thanks.
