I have done this multiple times at my dealer and they were curious as to why but ultimately happy to make the sale. Never have had an issue.

If you have a collaborative dealer, I would have them flash update your original and new ECM with the same files, as OS upgrades will make things apples to apples if for some reason you need to plug the stock one back in. I also emphatically agree in using a dealer replacement ECM as the...

ULVE Ultra Low Vehicle Emissions. The engine was slated to go there, never got there. I am very aware of the neural network, I have made 4 of them for this platform to work when using forced induction and the year of the vehicle. Yes the VE table is obsolete and is now calculated via the...

Be careful with how fast and wide you let the throttle body open in relation to fuel enrichment and cam timing. That one lever can quickly melt down an engine, as that creates transient response conditions faster that what the ecm can account for. The fuel quality tuning stock is less than...

The engine can handle mild boost, it is the valvetrain that struggles to keep things together and there are not enough diagnostics to definitively tell you things are going south. On top of that jeep detuned the diagnostics so a stock engine could make it out of warranty before you noticed the...

I have done 521 Supercharger tunes. Many of them have them have been successful, checking in now and then for updates. I assume it is about the same ratio as what Jeep is seeing for failures on the engine its self. The forced induction is not what makes the unreliable. it is the valvetrain. The...

I have an arsenal of safeties, which worked but I believe the 3.6 still managed to crack a ring land when the compression went up due to a valve not being open when it was suppose to be. Engine still runs and all but it has blow by. I had been working with Charles and I had a suspicion from the...

What RPM is it happening at? 2500 to 3000 is when the high lift part of the cam is engaged. If your oil is not in the best shape for a number of reasons, the cam phazer can be slow or fast. There is a cleaning cycle the engine auto runs on some operating systems but it is not en led on all...

I would try the halogen setting, if that does not work, you need an inline relay harness.

Just like there can be a perfect storm of bad stuff to end an engine I would say yours is a perfect storm of good. Using decent products, thermal cycling the engine, hot can be good in short duration as it burns off contamination, look at modern diesels. It does need to cycle through the rpm...

There are a fair bit of 3.6L that make it out alive, with out damage or mild wear. The problem with the internet is people mostly come here for advice on broken or under performing stuff. This thread will tell you about the propensity for the 3.6L to eat a valvetrain. It is a sore subject with...

42K is when I lost my right side cam 2020

I think oil temp is probably a fairly good indicator of, if and when the propensity for this issue elevated. If your running high oil temps on a frequent basis, it is more likely. Looking back on my thesis above, that is essentially what it boils down to. If your on the high lift cam alot it...

What gears, what tire size, what payload, towing no towing. How long is continuous 3000 rpm achieved? How often is your oil changed. What is the ambient temperature. 37s with 410s probably fine 500 lbs in the bed fine Towing 3400 lbs fine Ambient temps 95f or less with low humidity fine...

Whats alot of time? Minutes/hours all at once. Accumulating heat is what will kill it. My guess is you regularly change your oil and do it more than the recommended oil change. So you reset your additive package every 5k miles. People are putting huge wheel packages on these and then spend...

Well being that no recent developed valvetrain has been made with friction lifter follower tech, my guess is the oil and metallurgy is not designed for it. Neither one is up to the task of meeting todays requirements for milage emissions and heat. So of you spend enough time outside of the curve...

The current generation 3.6L fails the high lift lobe on the cam. When it is in high lift mode, anything beyond 2700 rpm, the high lift cam is not roller it is friction based like and old school flat tappet. Plenty of speculation around metallurgy, surface finish, and oiling needs. Many...

If you are having problems again chances are they did not replace the solenoids that trigger the high lift cam position. When you fail valve train these solenoids become sledged up with metal and debris, and then the cam does not phase correctly, thus the reason new parts fail soon after being...

No they constantly move while you drive. Phazers that stick or move slow will cause misfires stalling, and generally poor running at high load.

Additional symptoms would show up as misfires under load. If you inspect your oil filter you will find metal sludge. Also if you remove a cam sensor it will have a thick metallic paste on it. It is good yo get the cam changed as soon as possible and flush he engine about three times with drive...
