My idle didn't change at all, but I regret buying it because it is very inaccurate. It always read rich even when I was on the dyno running 13.1 AFR. I'm going to replace it with an oil pressure gauge.

See I think the problem with the A/F meters that aren't wideband is that they just read off the standard stoich reading of 14.7 (i believe) and anything below that is rich. But with turbo cars, the proper AFR gets lower(richer) as boost is increases, so the A/F gauge will always read rich when your car is tuned right.

Unfortunatley, those guages are worthless for our cars. Like 0110-m-p said, they are not accurate because of the narrow band. You need buy something like this to beable to monitor AFR's and have data to "tune" with.

WTB Wide Band O2 Sensor
The o2 sensor has to be a 5 wire out of a 92-95 Honda Civic, Non-CA, 1.5L VTEC. If you know the mileage on it that would be a plus.

AEM has a nice wideband 52mm gauge coming out. It has a built in UEGO, so no need for external boxes.

I will be installing the LM-1 soon. Let me get this correct. 14.7 and below is rich. And anything above that is lean. I will be running 14-17 psi and would like to run safely rich. What ratio would you aim for at that boost level?

Thanks.
