    My NW 102 wouldn't flow enough air through the IAC passage until I ported the heck out of it. With no other changes the IAC position dropped to somewhere controllable.

    I just happened across this thread this morning. My 2002 OS truck had the MAF DTC max shift pressure enabled. It seems like it's been 10 years shifting this way. I haven't been looking for a cure, I...

    It is the brushes in the alternator bouncing. I got lucky and a new, not re manufactured alternator fixed it. I think I got a Bosch, it's been awhile. It is especially dangerous when you have bad...

    When I first entered my two V/AFR into the list in scanner, instead of putting the .5 volt afr into the .5 v column, I changed the first entry from 0 volts to .5, and tried entering the 4.5 volt afr...

    Thanks, but they did not provide a list, only a graph and the .5V and 4.5V AFRs. My problem stems from trying to figure the 0V AFR. It is obviously not 11.11 if .5V is 9.0 AFR

    With my new NGK/NTK wide band, .5V=9.00 afr, 4.5V=20.00 afr

    When I use my data, I come up with (4.5-.5)/20-9=.045
    .5/.045=11.11
    0v=11.11
    4.5v=20
    4.5/(20-11.11)=..506
    volts/.506+11.11

    I tried both and ended up changing the numbers a few times anyway, until the speedo matched my GPS.

    Don't do that. Change it in the Gear/Tire Calc and click "Commit". That will rescale everything.

    I made a half-assed attempt by upping the whole table by 1.1 times. It did not seem to make up for me being too lazy to fix my poor idle tuning.

    Yeah, disregard my comment. My IAC stayed at 310 until I made the holes bigger.

    I can't look at your logs on my mobile, and I don't know if it applies, but this concerns your TB. I have a FAST 102 DBW, and I see that it looks similar to a NW. I had to hog out the idle air...

    Rescale TPS for 102mm TB?

    I was wondering if part throttle driveability might be improved, or improvable. It kind of has the sensation of a weak accelerator pump, but it doesn't really bog, it just seems lively when the...

    It now locks the converter at an indicated 52 mph, which is actual mph. It used to lock up at an indicated 50 mph, which was an actual 48 mph.

    You just need to make your tire size about an inch smaller in the calculator.

    I guess I should rephrase my question.
