dobek style box tuning cheat sheet

[Vertical-Extreme]

I wrote this up and thought it might be helpful for new turbo owners .
These modes are based on a race gas secondary injector set up

1.) (Mode 1 Green) Idle
2.) (Mode 2 Yellow) Midrange
3.) (Mode 3 Red) Mains no boost.
4.) (Mode 4 Green/Blue) Main injector fueling on boost
5.) (Mode 5 Yellow/Blue) Secondary injectors)
6.) (Mode 6 Red/Blue), this is the switch point for the red (lower the number the lower the rpm the higher the number the higher the rpm or switch point).
Tuning the settings:
Box will cycle through a couple times then settle with the green flashing.
Press mode to enter adjusting phase. Keep pressing mode to get to the desired mode you would like to tune. (See above) Note: colors will flash on the current setting they are on. When you are on the mode you want to tune, press the plus or minus button. The flashes will go from a fast flash to a slow flash; this will add or subtract fuel respectively. When you are finished tuning a particular mode, press the mode button and go to the next setting, or wait and the box will take itself out of tuning mode.

THis is a great write up but you need to be careful with the yellow/blue setting detail. You are right that it controls the secondary injectors on boosted applications but they don't all come on at 9psi. The attitude boxes usually come on at around 2psi where the pure logic boxes come in at a higher psi. Its all in who wrote the map for the specific Dobek box. It also maters 800vs 1000 because the stock injectors run out of fuel at different psi levels respectively.
Great write up though

So if you have it set for more boost and want to go down on boost what would you have to adj to get the fueling in the ball park.

Also on a 2 inj setup yel/blu does something different as well right?

So glad I don't have a 4 inj. setup... I love the stage II! So much simpler!

Thanks for the input I edited it an took out the 9 psi and stated the modes are based on a race gas setup with secondary injectors

mode 4 (green blue) is your boost fuel adjustment. Most of the time i can change around 3# and not have to touch the box

That adjustment is X-fuel/ #boost, so it should adjust as you go.

I can go from 7.5 to 15 on our 09 & afr stays within .4 or so on top. I guess I could be more picky, but it works.

Also, it has to adjust fuel at 1/2-3/4 throttle (on boost) and as you ramp up, so even though you're "running" 13 psi, you're also running, in reality 1-12 also unless you just go from idle to full throttle & that's it.

This is a good thread it helped out a lot now that I no what everything does. So if you got the secondary injectors and only running 6 lb of boost can you turn them off some kits don't even have them at all and run but have seen them get warm in a long pull not that I am going to but just wandering sled seems to be running pretty good now, I do no it is almost imposable to clean up the bottom end on a m1000 it is pretty good but if you are thinking you are going to do something cool and sit and think about it first you will look like a a$$ if you didn't clean it out first makes you think a bit more before you do something.

Mine is a twisted rg kit and doesn't have the Y/B whats up with that.

one thing of caution though. I dont think all Dobeck boxes are the same...I think there are different codes and impacts for different applications...

 

[WyoBoy1000]

from what I understand the box can be programmed to do what ever you want within its limits,

The attitude box does not use the yellow blue mode for tuning secondary injectors like the PL box does. from what I understand you have your red (mains) and your green / blue (boost) the pl box has 2 sets of lights for boost fuel adjustment. green blue & yellow blue

no they are not. I should have clarified this was written for a pure logic box, the attidude box does not use the yellow bue mode for tuning secondary injectors. the 3 "base modes are the same, but once you get into the "secondary" dual color modes they can be programed to whatever the programer wants.

 

[WyoBoy1000]

I was just putting it out there to clarify, I wish mine had it. Not that I need it just like having the option.

yeah they can almost all get re-programmed as they have the same components, but for instance my T-Nytro had a Dobeck box (private labeled fro NW Turbos) and it did not have the same controls as yours...

So, it is all very different, even from sled to sled...

I think most differences are from builder to builder, each builder has it setup for different loads and percentages in the ranges.

I was wondering which would work better. In theory the pl box should have more tuneability but the attitude should be easier to tune ( one less thing to mess with). In the end they both do the same thing

mine is attitude box and it has all the settings Green, yellow, red, green blue, yellow blue, and red blue, was told green blue is boost fueling yellow blue is secondary inj and don't mess with the red blue and of course red is main jet fueling.
