MAF TRANS GEN II

[1KWIKSIX]

Same price as the zone when it's all said and done. I don't like them by the way. Might as well do business with sponsor.

What's the difference between the 1000 and the 1001?

Dunno what the difference is, but the 1001 sold by NOS4GN is the correct one for our cars. I've bought several over the years & they work great!

These are the scanmaster reading. We need to know the setting inside the GenII "Maf In" and Maf Out" .

Ok exhaust leak is fixed. I have similar numbers minus the knock is is 1.

Above 2000rpm the o2 is >750 but at idle the o2 is 41.

What next?

First, do you have open loop idle enabled?

Key on engine off, scroll to int in scanmaster. It should say 12. Hit the mode button 1 more time to bl. It should say 0. Use the gas pedal to make bl say 4. Hold the pedal on 4 and turn key off. Now you can use the O2 millivolt# to a certain point to tune but you need to get the wideband hooked up to be accurate. Keep in mind the O2 sensor need to get to temperature before it will read and only has a very narrow range.

Start the car let it warm up. Idle fuel can be added or subtracted in the low tune page at 800-1200 rpm. I usually go %5 at a time. Target upper 700's low 800 O2 millivolts.

Yes, very narrow! That 41 he's seeing at idle would equate to about a 15.5:1 AFR

Ok, I've done it. The o2 mv are not changing highest I got was 51 at about 35% more than that car will not run. Car idles between 1000 and 1100, sometimes 950 if that has anything to do with it.
Ton of power since I got the leak fixed though. At 1900 rpm everything is fine. There is also almost no in between, it's boost or no boost.
