Timing Reduct Scaling

I'm going to check and see if I understand this option correctly. Basically, Timing Reduct Scaling basically affects the Max Load Timing Offset vs APPS Sensor. So if I set the Max Load Timing Offset to 3* and then the Timing Reduct Scaling to 50%. so by the time I hit 50% on the APPS sensor, the timing should be maxed out on the performance side. 

[Me78569]

Timing scaling sets the max timing pull possible.    %100 being you get %100 of the timing reduction called for.  %50 means you get %50 of that 3* HOWEVER it ramps up as if it was going to 3* So you will hit 1.5* max timing pull at %50 throttle input rather than 1.5* at %100 tps input if you were to do %100 scaling with 1.5* reduction.   

 

 

 

so in the example below. 5* at %50 scaling vs 2.5* at %100 scaling.  Both can pull a max of 2.5*, but the 5* with %50 scaling pulls timing faster related to TPS input.  It will pull timing 2x as fast but the peak pull is still 2.5*.  

 

 

the scaling is nothing more than a limiter.  The perk of using a limiter is it will pull timing more aggressive, as if it was going to pull 5*.

Ok you've lost me again. I'm trying to figure out what setting are being used against this Timing Reduct setting. I know the Max Load Timing Offset is only a 0 to 3* limit. So where are you getting 5* at? Are you talking about Low PSI Timing Reduct that is a 0 to 5* span. 

 

I'm trying to get the setting that this works against and understand how it works correctly. First lets list out the variables this actually works with. Then let work with how the math is figured out. 

[Me78569]

Low PSI Timing Reduct is what the Timing Reduct Scaling variable uses.  

 

So low psi timing reduct is 0-5* of overall timing pull possible when you go WOT.

Ok. Now it's coming together. It's hard to use a setting if you don't understand the information it's using and from where.

This is where the app really needs an info button beside each parameter with a description. I mean sure, a guy can have the manual with him, but a built in app description would be the icing on the cake.

Absolutely! That would be awesome if Quadzilla would add that.

thats a huge change to the way to data / app work together.    Keep in mind in order to make this work across multiple platforms the Entire .json structure has to changed to hold a memo field that references a url per variable.  

 

That is a HUGE undertaking.  

[Mopar1973Man]

Dang... I thought it would be some sort of data within the actual App itself. Oh Well... 

[Me78569]

Not possible since the app is used for a ton of different trucks.   There has to be some sort of link somewhere to say this truck with this profile gets this aid which gets this memo field

[kzimmer]

Well, then just another "help" menu in the custom tuning area that explains all parameters in one shot. This of course assumes the parameters are in final revision and won't be changed.

[Me78569]

lol I haven't touched the code in awhile now.  

 

still needs to be json driven on a per profile setup.  There are 180 some different tuning variables when you look at the complete list of all vehicles.

So when you say "low psi timing reduct",  what is defined as "low psi" in numbers,

Example: psi less than 3 psi or less than 10 psi  or ? 

 

Thanks for any clarification.

the map is based on Boost and tps input.  0-10 psi and 0-100 tps.  

 

 

WOT and 0 psi gives you %100 of the pull defined by the variables.   If boost is above ~5 psi then you have to be pretty heavy in the throttle for the pull to have much effect.  At 0 psi you will get a significant amount of pull above ~%30 throttle.

Thanks for this!

Ok so I’ve been fooling with quad settings and I think this belong in here. Currently have a bit of a surge when using cruise control. What settings would I be looking to change to adjust for this?

[Me78569]

define surge

[notlimah]

Just not smooth as it can be when adjusting tps to maintain speed 

[Me78569]

is this a fast surge or a slow on and off?

[notlimah]

It’s just like it’s over compensating for how much throttle it needs to maintain speed. Surge was probably the wrong word to use lol.
