Geesh! My luck the accuracy was the worse tested. I hope mine is on or reading leaner than actual.

I'm gonna setup to do a WOT run and shut off durring it to coast down and read the plugs. The pics above are after a WOT but then a 1/4 mile slow driving to the garage.

guess my aem is not so bad..only thing i dont like is when it gets richer that 11:1 no more display...i hope when i start logging the serial output i get real numbers

Which one do you have?
The gauge (30-4100) has a Measuring Range of 10.0:1 to 18.5:1 AFR (Gasoline)

Part #: 30-4121

Yours seems to have an output range of 11 AFR - 16.75 AFR.
Serial to v2 is very nice.

The V2 pin out is in my sig.

ordered my cable last week...cant wait...all i need to to is set up a pid to convert my external 2 bar map (for boost logging only) from voltage to boost...have no idea how yet...then i will have a true set of logs for fine tunning

sorry about the long log...not really sure on how to cut it down but the higher rpm\s start at about frame 900....i have included my tune and a xls chart for the external analog input 1...its running a 2 bar map from my meth kit for logging boost....since we are on the topic of fuel...i plan on pulling down from a 3.6 pulley to a 3.4 pulley....it should give me 2psi more....where would i make changes to keep all safe??Also this run was down using no meth
Thanks for any help
