So I've been so used to a straight pipe exhaust and easily hearing VTEC engage but now I got a res and muffler installed it's alot quieter and I can't tell if VTEC is engaging or not. I have a turbo b series where full boost hits at very low rpm. Would you see in your AFR's if VTEC wasnt enabling ...

I watched it yesterday and it is reading the same as the battery, had my volt meter hooked up to make sure. That short datalog must have been from when the fan was on.

I had my alternator checked out and he said its putting out 14V. So... It isn't normal to drop in voltage when the cooling fan is on? I checked my dead times and they were slightly off so I changed those as well and I still get the slight surge in AFRs

Hey guys I was hoping someone could help me figure out why my tune at idle isn't smooth, the AFR gauge bounces between 13 and 15, it just doesn't sound right. I unfortunately don't get a response back from my tuner who is about 6 hours away so I thought I would try here. I will attach the data log ...
