Section 1: Custom Tuning V1

The v1 of custom tuning allowed for these changes to be made to the base tunes.  I have split the custom tuning into sections to better explain the effect each has on how the truck drives and how much power is put down from electrical fueling.



Max Power Levels


Power Levels :  lvl 0 stock | lvl 1 timing | lvl 2 Canbus fuelings (65 hp) | lvl 3 + Wiretap fueling (+120 HP in addition to the 65 hp from CANbus)   You can set the minimize power levels to 5 or max to 14.  


This will give you more or less wiretap levels,  Note that no additional power is made by setting max levels higher.    Rather setting Max Power Levels higher give you more "steps" of wiretap fueling until the max is reached.  


IE: total power lvls = 5 gives you 2 wiretap levels (Remember to always could lvl 0 in your total lvls), so lvl 3 will give you %50 of wiretap stretch and lvl 4 will give you %100 of wiretap stretch whereas setting your max lvls to 14 will give you 12 steps of wiretap fueling lvl 3 would be 1/12th of wiretap stretch lvl 9 would be 7/12th of wiretap stretch and lvl 14 would be 12/12th of wiretap stretch



Wiretap Fueling: By tapping the fueling solenoid wire on the VP44 you can watch for a fueling trigger from the PSG and extend based upon how much fuel is required by the Quadzilla.


Max Pump Stretch:  sets the upper limit for Wiretap Fueling time.  Typically 2200 is the max on the aggressive tunes.  This is what allows for the calculation of how much pump fueling to use.  Remember that you are setting the max amount of fueling.  This fueling time is altered by many different inputs such as, but not limited to, boost, rpm, APPS, etc  on v1 base tunes lvls 3 - max divide the max stretch by the span IE: if you have 10 levels total 4-10 are wiretap so you have 7 lvls of wiretap on lvl 4 you get 1/7th of additional wiretap fueling, lvl 5 you get 2/7th and so forth. 


Setting Max Pump Stretch higher may reduce total power while increasing Torque under the curve.  If you want upper-end power you would not want to set this to the max.   If you want low-end torque you would set this higher.   Typically people find that 1600-2000 is the happy spot depending on your injector size and driving style.  Smoke output will be increased by setting Stretch higher.



TPS scaling functions:  By watching TPS / APPS input from the driver the Quadzilla can adjust the fueling curves for both Canbus and Wiretap fueling.  This is helpful to tune the Quadzilla to your driving style and can help cut down on low end smoke.  



TPS Pump Max:  This allows for you to set the upper limit for TPS input for wiretap fueling.  Wiretap fueling does not stop at this point, rather it peaks at this point.    Using the max and min settings you can move the wiretap fueling area around within the 0-100% TPS range.


TPS Pump Min: This allows for you to set the lower limit for TPS input for wiretap fueling.  Wiretap fueling will not start until this point is reached.   Using the max and min settings you can move the wiretap fueling area around within the 0-100% TPS range.


TPS Can Max: This allows for you to set the upper limit for TPS input for Canbus fueling.  Canbus fueling does not stop at this point, rather it peaks at this point.    Using the max and min settings you can move the Canbus fueling area around within the 0-100% TPS range.


TPS Can Min: This allows for you to set the lower limit for TPS input for Canbus fueling.  Canbus fueling will not start until this point is reached.    Using the max and min settings you can move the Canbus fueling area around within the 0-100% TPS range.


Effectively by settings the max and min you are compressing %100 of the fueling between the max's and Mins.  


IE: maxs at 75 and min's at 25, or cutting the tps range to %50.   You will effective double the fueling ramp up once %25 tps is reach until %75 TPS is reached.  At %75 TPS input fueling will max out until %100.   No additional Power is made, rather the unit can tailor itself to your driving style.  This can be used to help low-end spool or help with City driving to keep power down.  If you set the min above your typical DD TPS input you can disable fueling when you don't need it.


Timing:  Timing is what controls the point in the stroke where Diesel is injected into the cylinder based upon the relation of Degree's to TDC.  


Timing Limit: 0- 15*  This will allow you to add timing above stock and above the timing built into the Quadzilla Base tune.  IE: this is NOT how much timing the engine will see, rather how much increase you will see in addition to other factors.    Setting timing higher will typically increase MPG when the engine is at a steady RPM at a steady load, IE: highway driving.  However, it can be risky to set timing above 7* without the correct mods.  Also, Low-end smoke is increased when timing is increased.   Timing is NOT scaled based upon power levels, rather is it applied the same on all levels that have timing increase.

Timing Scaling: 0-%100 This allows you to set how much timing gets pulled from the timing max number set.  You may want more timing down low, but want to pull timing up top.  


IE: Setting Max timing to 10* but scaling to %50 will give you 10* down low but only %50 of that up top so 5*  Setting scaling to %0 would give you 0* up top, while keeping 10* down low.  This is scaled so as you get higher more and more is pulled until the %0 is matched.  This is not dependent on power lvl rather the placement in the timing map based upon multiple inputs.  For the example think of it as pulling more timing based upon scaling in relation to  increasing power output.  



Boost compressed air from the turbo.  Fueling is directly related to boost, too much fuel for a given boost level will cause smoke, EGT issues, and lower power output.  It is important to tune fueling to boost.


Boost Scaling: 20-40 psi  Allows you to set the point at which fueling is maximized based upon boost levels.    Setting this to 20 will give you fuel fueling at 20psi, assuming tps min / and maxes are met.  Boost scaling is calculated along with TPS scaling so in order to have %100 of fueling both need to be met.   



As a reminder the custom tuning only alters how the base tune loaded fuels.  You cannot fully alter the tuning maps based on custom tuning.  The Above Custom tuning items allow you to move the map around within the limits of what is loaded on the base tune.    





Please consider updating your Quadzilla ADR1000, ADR1001, or ADR1002 to the V2 Tuning
