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.
That's different than mine.
Don't do that. Change it in the Gear/Tire Calc and click "Commit". That will rescale everything.
It has to be at 14.7:1 for the cats to work their magic.
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.
Good question. Here's a TTT for you. I think Ill try it.
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...
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.
... I checked "Yes" in autoscale transmission tables. ...
... The auto scale function changes your shift/lockup points to maintain the same strategy/keep engine rpms in specific areas. ...
You just need to make your tire size about an inch smaller in the calculator.
I guess I should rephrase my question.
Why, when I change the tire size in the calculator and now have the speedo...
I had the same problem, a new Bosch alternator, not a rebuild, solved it. I understand that the brush springs available to the rebuilders bounce at high rpm, effectively shutting the alternator off....
I replaced my 29.875 +- tires with 32.5 inch tall tires. I put 32.5 into the gear/tire calculator and committed to the changes. The speedo reads 42 when I am doing 40 by GPS. I changed the tire size...
Maybe he is such a good tuner that he only needs 2° knock retard. :rolleyes:
I was just trying to trick you into telling us something about the car.
This is the wrong section to post questions about diesels.
