Question: LLY vs LML
CP3 conversion, first off... There's 2014+ CP4's failing up here. On my 2011, pre-lift pump and with the catalytic converter still in, I pulled a 468HP and 850lb-ft of torque with my 2nd hottest tune. And got a 17.1 @ 86MPH in the 1/4 with a three second lift of the throttle to refill the...- drperry

Remote start
If your fuses are good, then mayhap something got turned off in the tuning... I'll browse the LML base file and get back to you, if it has something in it for those. -

first diesel and i'm hosed - cp4 out
I got lucky with mine, and I was just starting to show evidence of metal on the FPR... Just wouldn't build fuel pressure after checking the FPR... If possible, check/test your injectors. But do yourself a favor, and convert to a CP3. There's been 2014+ CP4's shitting the bed up here. Possibly... -

Remote start
If you clear any codes, it should start for a second or so, and shut down, for a glow plug. If it doesn't even fire, it's possibly something else... -

LML Dans Diesel Work, and CP4 failure
I'll take mine apart when it gets back from my surprise CP3 conversion, lol. Compare pics... But yours looks similar to the one my mechanic uses as an example... The rollers tend to go. -

2015 lml stock exhuast size
DPF back is 4“ ish... Between DPF and cat is 3"... There's parts that are 2.5", and not just the down pipe. -

LML Dans Diesel Work, and CP4 failure
The more fuel returned, the more potential for condensation. When we park our big rigs for the night, it's always with a full tank of fuel to reduce the amount of possible condensation... Not to mention days that go from below 0 to 70 above, and back below 0, lol. It's not always from bad... -

Fuel filter
Just going by information passed on. Worth a shot when you're stranded on the side of the road, lol -

"OFFICIAL" What did you do to your D-Max today?
Got yelled at by my LML to change my fuel filter again.- drperry

"OFFICIAL" What did you do to your D-Max today?
A couple days ago,but changed all the fuel filters/water separator, and air filter... The S&B filter was wrinkled, lol, so had to buy a new one... Also, my first full WOT run since the new filters, and my my fuel filter life went to 0... Not good.- drperry

LML Optilube
On an LML, two stroke is bad. On older style machines, it's ok, and can help, but the newer injectors don't like it. Stick to a good additive.- drperry

LML Need Opinion
The first run of CP4s are hit and miss... Swap out the factory intake, unless you change your air filter often... The plastic webbing that holds the filter flat can let go and get sucked into the turbo. I don't know if that's a tuned truck only issue, though. My intake had a few cracked pieces... -

Fuel filter
Also helps to unhook the power, if the fuse didn't blow. If it's the electrical side of the motor that crapped out, having power to it can lock it in place. You'll still be pulling fuel through the FASS filter, but might as well as keep the stock filter and double the mileage between changes... -

lift pump question
I have no sump on my 2011... You only really need one if you need high volume, or the internal pickup is otherwise impaired. The 1/4 tank problem only happens when there's a large amount of debris in the tank that plugs off the factory screen. I bought my truck used, so I puckered before I got...- drperry

Lml fuel/boost issues
Well, it looks like my fuel pump is doing it's business just fine... Rail pressure is always within spitting distance of commanded rail pressure... It appears to be the turbo vanes opening that's doing it... I'm just not sure what would cause that, as it did it when it was on stock tuning... -

Commercial Truck and GVWR
If it's like here in Alberta, you're more limited by individual axle weights for truck capacity... You'll be able to license for road limits or manufacturer specs, whichever is lower. -

Lml fuel/boost issues
It is in Canada... It's 2 - 3k for the kit with pump... Plus labour @ 100/hr or so, give or take. The exchange rate is killer on parts, lol. -

Lml fuel/boost issues
I'll double check after work, but I think so. I got my first fuel filter warning since the FASS last week or so... The filter is only a month or so older than my lift pump. If the demanded fuel pressure drops as well, what could cause that? It's done it since day one, even on stock... -

Lml fuel/boost issues
I'm aware... But it's a big chunk of change to swap out, so I want to make sure before I do a CP3 conversion. That's around 5k, give or take. -

Lml fuel/boost issues
So I'm thinking my CP4 might be on the way out.... But looking for other options. I can be cruising at highway speeds and my fuel pressure will drop 2 - 3k and a couple psi of boost... Or at least, you can hear the turbo change pitch, and possibly a small rpm drop as well. I'm running Idao...
