Yes they do.

New High Idle Switch
No. Quadzilla is not required. No. The switch is my design. I developed it to allow you to control the Cummins ECM high idle software. So if you looking to warm up your Cummins quickly then this switch is for you. There are other tricks like using the 6 cyl mode for keeping the alternator up while jump starting. Using 6 cyl mode for cool a hot truck off before jumping in the summer. Don't get wrapped up solely on just warming up but there are several other things a high idle kit can do. Yes, this switch can be used with a Quadzilla Adrenaline too.

@dieselautopower where is your Quadzilla crew?

Tester should work but you are going to need the collar fitting for coupling you injector to the test stand.

Sure. Just do me a favor? Please post up what you got and how you did the pop test. The article database would love to have a new one for pop testing.

Mechanical injectors require pressure to open the pintle to fire. As the injector wears the pop pressure falls and timing advances. This is the down fall to 24V injector systems. To keep timing correct you need to at least have them tested to see if they qualify. Yes I know 24V injectors could be completely wore out and still run and drive. Again the only way to verify is to remove all 6 and pop test. But keep in mind efficiency will degrade and possible to blow a head gasket from the advancement of the worn injectors because your mechanical advanced timing with boost and bye bye head gasket. Because as pop pressure falks its opening early. So for longevity I highly suggest pop testing injectors. I've seen 40k injectors sink to 280 bar because of shim failure. 293 bar = 4,250 PSI lower limit 327 bar = 4,750 PSI upper limit 310 bar = 4,500 PSI set pop pressure.

Gear oil
- Questions..
Try calling a local body shop that does body work they should have a book of measurements for reseting frames and body mount locations so parts will fit when replaced.- Gear oil
No benefits other than shorter life span and early failures. Too thin when heated to 200°F that fluid will be too thin and the hardfacing of the gears will be lost and gears will start breaking. I changed to 50 SAE trans fluid used in Eaton Fuller 10 speeds and stopping the hard face failures of the gears. If you want I dig up my broken parts to show what happens to using too thin of lube in a transmission. (NV4500).- Questions..
Don't use factory fluids! I've upgraded to SAE 50 Eaton Fuller transmission fluid and doing awesome at 500 HP. Factory fluid is too thin and bearing and syncro damage occurs because the HP went up but the fluid is too thin. Factory - 75w-80 is actually 10w-30 engine oil. Then Eaton Fuller is 50 SAE is actually 90 weight gear lube. No issues with shifting even as low as -40°F.- Gear oil
As long as it meets the specification there is no reason for expensive oils. I've stopped chasing high dollar oils a long time ago when a member @dorkweed went 84,000 miles on a single oil change using Walmart SuperTech engine oil and was doing Blackstone test every 7k miles and continued to keep passing the test with flying colors. I use 80w-90 petroleum in the axles (open diff), 50 SAE trans fluid (syn GL-4), Dextron ATF in the transfer case. I save money this way and 481 k miles later no issues now that fixed all the damage stock 75w-80 did to my transmission. Transfer case doesn't require ATF+4 syn oil so Dextron works just as well. Yeah call me crazy but closing in on 500k miles...- 1999 24v cummins changes engine tone while keeping steady speed on highway
That's what I know after working with DAP on my current injectors. Which I'll admit I'm pushing past 100k limit because I was set higher than 310 bar. I've got a trophy injector in my tool box I was the only person that could hear the fact there was one injector popping wrong. This was on a Case backhoe. The injector was missing a hole. Yes I'm very sensitive to picking up on bad injectors by ear.- 1999 24v cummins changes engine tone while keeping steady speed on highway
Specs according to Dodge FSM Minimum pop pressure 293 bar (4,250 PSI) Maximum pop pressure 327 bar (4,750 PSI) Set pop pressure - 310 bar (4,500 PSI) Then the engine load has hit zero because the pop pressure is too low and the ECM no longer can control the set idle speed being the injectors are popping open too early and too long and idle control is lost. If all 6 injectors were pulled you find when tested like mine at 150k miles DAP tested mine and they were at 850 RPM and zero engine load which brought mine down got 240 to 260 bar. Which is unusable timing is totally off and too advanced in timing. Hence why when I had these 7x0.010 injectors built I opted for 320 bar for longevity and better spray. So far I'm still idling at 800 RPM at about 6-7% engine load so the injectors are still within timing and not popping open too early. Like I'm learning with Quadzilla tuning 290 bar injectors are a PITA being they are right at the breaking point of failure and over-advanced by about 4 to 5 degrees and require a tune that is retarded. My tune has to have more advancement being I'm set above 310 bar so I've got to add more advancement being I'm about 2 to 3 degrees retarded. All are based on the 310 bar set point of where the timing will be.- Air leak Hard start in the morning.
Another passing thought. For those who bought injectors popped lower that 310 bar will have issues finding proper timing. Clue is below 310 bar RETARD, above 310 bar ADVANCE.- 1999 24v cummins changes engine tone while keeping steady speed on highway
With the little displays yeah too old. Should use your cellphone or mobile device likat a tablet. I'm pretty sure you could change out the display for the radio head (BT/WiFi) then update the firmware to get to version 2. Just easier to get a unit with the radio head and just plug in.- Build forum, comments / suggestions wanted
I was spun balanced back at about 350k miles. Changing a u-joint went bad damage the rear u-joint of the rear shaft. When it was rebuilt new end welded in, the new carrier bearing and 3 u-joints with a spin balance.- 1999 24v cummins changes engine tone while keeping steady speed on highway
Be aware the injectors can wear to the point idle load will drop to 0% and idle speed could be as high as 900 RPM as I seen on one truck I replaced injectors on.- Wrecked 2000
Hua???- Air leak Hard start in the morning.
Again another example I can run 26 to 27 degrees of cruise timing at 2,000 RPM but I'm always below 5 PSI of boost. This is why I monitor my engine oil temperature because to advanced engine oil temperature will rise up past coolant because the amount of flame on the cylinder walls. Also watch engine load numbers it will rise because of negative torque.- Homemade vp44 and ECM arduino project update #4
Check out @Auto Computer Specialist for replacement ECM. There isnt any new ECMs only reman'ed.- Air leak Hard start in the morning.
You can run quite a bit of timing as long as the boost is near zero. No more than 5 PSI for above about 22 to 23 degrees.- 1999 24v cummins changes engine tone while keeping steady speed on highway
