Hey guys,

 

I have warm up mode and high idle activated with a 90 second delay, until 140°F ECT. I want to verify intended functionality. Here's how mine works.

 

After the 90 second delay, my tach jumps up to about 950 ish. After about 10 minutes, they smoothly increase to about 1200. Does this sound normal? I'm not sure if the two-stage RPM is intended or not. I would kind of prefer to see 1200 RPM instantly when it's cold out.

    I actually don't mind it, i used it few times to back up at a steady speed lol. And once I was on some sleek dirt going up hill, so I put it in 1st 4x4 low and high idle on and walked beside the truck

  • Due to the size of the injectors I can't say if it is not normal.  It takes a good bit more fuel on a cold motor to get RPMS up.  as the motor comes up to temp somewhat then it takes less fuel and rpm

@Mopar1973Man will high idle stay on as long as selector knob is on 3 or 6 position of your switch?

 

Yes and no. 

 

3 CYL cannot be held. It will self-cancel after coolant reaches 170 or so.

 

6 CYL can be held if the selector is left in the 6 CYL position. If you start the mode and select MPG or OFF it will self-cancel as well. The 6CYL mode was set up as a locked mode for people that need high idle for other purposes like jump-starting a vehicle for example. 

 

There are a few bonuses to Quadzilla high idle as well. If it set up you can enable it by just selecting level 0 and the high idle will engage as soon the timer runs out. Where with M73M high idle the timer is much longer and always that possible chance of the selecting the mode might pick up 3 CYL because the ECM picked up -40*F or the small period of time where the switch broke contact.

 

There are a few problems with Quadzila too. I've found it does not detect road speed so a manual transmission could place it in gear and idle along with high idle still engaged. This should disable the high idle on Quadzilla just like it does on the factory high idle. (BUG!). Throttle change is very sudden jump to 1,200 RPM it needs to be ramped up slower it creates a violent thump are it jumps to RPM's. (BUG!)

That’s one thing I don’t like also. It startles me most of the time when it jump up to 1200 rpm even knowing that it’s going to do that ?

Actually it does look at road speed.  The bug about it ramping up too fast is a damned if oyu do and damned if you don't if we put it back to the way it was it doesn't work for %50 of the people.

That was my main concern, because I'd be using that 6 high idle if I'm jumping or winching, and will probably unplug qwadzila at that point. Thinking about putting power wire on toggle switch for quadzilla the one that goes to the battery, that way I don't have to pop the hood and unplug it every time. Unless it can back feed from other wires and still fry it.

When I put it into gear (Auto) while in high idle, it's pretty violent. Not a huge deal, just need to remember to bump the throttle before I put it in gear.

I actually don't mind it, i used it few times to back up at a steady speed lol. And once I was on some sleek dirt going up hill, so I put it in 1st 4x4 low and high idle on and walked beside the truck for a little bit observing it, I'm weird like that.
