eCtune

just wanted to post an update. I ended up doing the offset manually. so 11 afr = xx voltage. if you know what i mean. I subtracted almost 1 volt and its pretty consistent now. Im running straight from the battery to the wideband now too.

Should I put the 1Mega ohm resistor in r136, r138 or inline on d10? Thanks for the input guys. I was running the wideband off the cig lighter I will move that to the ecu power too.

Im bring in the wideband input to D10. I set ectune to zeitronix and compare the display of both. The zeitronix reading is 15.5 and the ectune is reading 19 afr. I try to adjust the offset in small increments the went as far as + or - 2.5 volts and the most it would change is to 17.5 afr. The one th...
