After driving for awhile I notice the service engine light on. Scan tool plugged in and I have and 02 code. Switched it off started the truck all is cool, driving to work the scan tool popped Bank 2 02 fault/ My question for now is which front 02 is bank 1 and bank 2(driver or passenger). I have a feeling its the one before the turbo..
Now on to another ?.
Timing at cruise is 44-46 damm that seems high to old carb guy.... Under a load drop down to 10-12 and starts to work back up, Is this normal for these trucks...


The truck is real peppy , looking at visiting our dyno with in the next 2 weeks, fuel plate and dual wide bands are due Friday.. So some more wiring and when the water/meth shows up a litlte more wiring..
So far all the heating issues that I thought I might have do not exist, engine runs cool even in 103'F. The intercooler up front does not seem to effect anything either, trans temp good to go.
More up dates to follow.

Bank one is the drivers side 1,3,5,7...Bank two is the passenger side 2,4,6,8.

Timing will be sky high at low kpa. This is one of the things that gives you great fuel economy in the newer vehicles. YOur total somewere around 15 at 100+KPa or a little more?

Looks good, should put down some nice numbers.

 

Hmmm Bank 2 seems to work until I get on it a little.... I will swap it and see what happens. Thanks

Might check for an exhaust leak around the o2 sensor.

 

I will check that, thanks. This weekend I will swap the front o2 and see if bank 1 freaks out. Hot pipe have to come off for a moment to install the wideband stuff, so should be easy enough to check for leaks, and find that one I can hear at first start up, tick tick how anoying.
