When you disconnect your notebook, what are you using to read the AFR 11.7?

11.7 is dangerous if the tune isn't set up for it, that's all up to the tuner.
Maybe the map isn't flashed in? hmm, kinda odd. -Mark |

I don't see how hooking up the AFR gauge to a notebook would actually change the actual AFR...
The wideband and it's 02 sensor is a "standalone" system, apart from the ECU. So whether a notebook is plugged into the gauge or not, should have no impact on the actual AFR's. I have a feeling it might be related to the gauge itself not reading correctly either when notebook is plugged in or when it is not. I hope it's not the first possibility. |

It's the gauge. Try a different one.

I know this might sound crazy but I had a similar problem with the innovate lc1 and it turned out to be a crappy grounding spot. Check your ground wires to the kit.

Try an AEM UEGO WB gauge. I have read a few posts about this same problem with Innovate LC-1 gauges.

try using a different wideband and then let us know if the results are the same or not. I would do what you were told mate haha check if there's a crappy grounding spot. Often bad grounds have a lot to do with the car electronics. My dad's altezza was running like crap. But honestly, the car wouldnt even starts some times. And it ended up being a crappy grounding spot. Hopefully that your issue and not the wideband. Over here in chile these things are expensive. Take care mate see you around!

Innovate LC-1 is by far one of the worst gauges ive had, always go AEM UEGO. Switch gauges and go from there.

also is your bypass valve recirculating back into the intake like it should? or is it venting 50/50 into the atmosphere? it seems like it leans out a more between shifts.

It should run richer between shifts since the air is being evacuated instead of plumbed back to the system if anything.
I wonder (very odd question), any way you have a ground loop that's causing electrical malfunctions when there is a draw from the laptop? It can also happen when there is too much voltage and the voltage drops from the lap top taking juice.... If by some chance you have electronics in the car like audio or whatever (aftermarket), ensuring that everything is routing as it should be might make a bit of a difference...just in case. Other than that, look into a new gauge but my thought is that you're having the issue from electrical draw more than a gauge. -Mark |
