I havent been able to start the truck yet but I thought that when I turn the key on it would stay at whatever normal air is. Isnt normal air naturally like 14.7? It dances around if I leave the key on. Here is a video of what it does, I just want to make sure Im not going to screw up my WB when I start the truck up. This is my first WB, soon I will be the owner of HPT to start tuning this **** myself.

 

In open air my WB maxes out at 20.0:1. 14.7 is a mixture of air and fuel, so when there's no fuel it should read really lean.

I just watched the vid too, it seems weird that it would dance around but it looks like after it was done it settled on max lean.

 

Im an idiot, 14.7 is natural atmospheric pressure

Maybe Dewey will see this and check his DJWB out for me after he gets a battery back in his truck

 

My WB is full rich (9) while its in warm up mode, then it's full lean (20) after it warms up and starts reading till I start the engine. Looks like that's what yours is doing.

 

I say normal. Mine is digital but when I key on it flashes a couple of reset codes and does the same thing. You have no fuel in the pipe so it is going to read lean off the scale.
Yes atmosheric pressure is ~14.7:1 but your sensor is reading Fuel/Air....doh!

 

Mine pegs out at 20 when the engine is not running.. but at idle mine reads 15.2 and 11.2 when in boosts.

 

come on dewey I know you have DJWB where are you?

 

Looks perfect. It will even do some other wild stuff here and there. On really cold days it won't go to the real lean side...like there is fuel laying around in the pipe or something. Looks good to me.

 

Thanks Dewey

 

I was thinking after I posted...let me make a vid. FWIW the first try mine sat on 14.7 for a good 20 seconds before it did a "cycle".




oh and btw, here's hwo I got home Friday...
