Wideband O2 to AFR controller to ECU Hey guys. I installed my MXT-L AFR controller along with a bosch style wide band in my driver side bank. I need to know the voltage output from my o2 sensor that my ECU needs to read lamda (or shall I say lean/rich) as I can define this in my controller...

Hi, I just got an A/F from autometer. This gauge has the feature that it turns itself on when the battery hits 13.8 volts, witch means it will not turn on before the engine is started - in theory. In real life I have to rev the engine up to about 3500 rpm to get it to turn on. What is most...

Hey All, I recently ordered an SCT SF3 tuning device and when I plugged it in to my 2003 GT nothing happened. I tried it in my brother's 1999 GT and it turned right on. After some investigating I checked all of the fuses and none of them were blown. I grabbed a multimeter and starting poking...
