That is what I thought. Although the time varies from 1 minute to 10 minutes. It seems that if I put too much load (above 63%) on the car for any reason in LB, it will go into OL a lot sooner. Tygen1 said that this is just a quirk to our setup, and is normal.

I filled up last night... And really wish i didn't. I got 47.5 mpg this time around, which is exceptionally good for the ZX2, but my worst fill in over a month! My ScanGauge reported 56.6 mpg and needing 5.9 gallons. It took 7.2 gallons

I'm at a total loss as to how it could happen. Is lean burn not workingand could it be tricking my ScanGauge? I feel the power loss when I flip my switch, so I know something is happening... I really need to get a wideband O2 so I can see what AFRs I am running.

Help!
