It's too bad quadzilla doesn't explain their product a little better with youtube videos, more in-depth instructions or?? , just generic bare minimum, leaving people like me scratching their heads not knowing up from down. I really gotta wonder if they even understand it as well as you?

It is explained in as much detail as I could   There is even a youtube video..

LorenS, thanks for taking time to clarify!

Glad to hear it wasn't just me 😂

So, do you just leave it at 40% now  for all driving conditions or do you or should one change it if you're going to be changing from 70 to 80 for a while , or you're going to be driving slow city stop and go for a few days?  That's how it is here where I live.

Have one tune for cruising 70, one for 80, city, etc ??

 

I think it's hard to understand how compeatly confusing this stuff is for someone that's new to the diesel world, (myself) hence why I joined the forum.

Even in the "gas world" I know my way around most aspects of a vehicle but I am no gear head/engine mechanic or tuner, were one plays with and really understands timing, and how it affects mileage/power. My specialty is auto body/ collision repair.

 

  Still need to get out and do this, like I said not my daily driver, (partially because of mediocre mileage) but should have enough info now to get this done!

 

 Thanks again to all for help and patience!

I don't believe changing it should be necessary.  If you set that Low Load Timing just a couple of percent above your normal, flat ground cruising Engine Load at say 65-70 MPH, then you know the engine isn't straining and can handle a little 'stress' of advanced timing.  If you're going 80, or 65 up a grade, or towing a trailer, then the engine load will be higher and the Quad will not allow the higher timing, thus saving your engine/head/etc.  With your bigger injectors, you likely won't have a cruising engine load as high as mine.

 

It is recommended to have different tunes for different things, like Towing versus Sportscar or Economy; towing you will likely have long duration of heavy load, and also will want to get moving even at the cost of a little fuel economy.

I'm no expert at any of this, either, so if I said something wrong hopefully one of the more knowledgeable guys will chime in.
