Just as the title says...

Will it be a programmer or fuel module?

Will the exhaust system be a problem?

 

My guess will be SCT and a program from LIPD. They seem to be on the ball when it comes to programming and FORD's. The question is who will be the first to try it. It is well stated that Ford will void if programmed so it will have to be someone who has some cashola or works in the industry....

 

I know someone who can....

Depends on how it is tuned.

 

The problem with tuning these engines is this... Currently they operate in a High NOX/Low soot mode so the DPF doesn't have to regen as often. They regen based on a calculated soot loading using known variables. Since the DPF doesn't have a Delta P sensor to measure backpressure, tuning the engine to produce more soot may eventually plug the DPF before it can regen, unless the tuner has the capability to adjust the regen strategy to compensate.

 

The 6.4L Ford DOES have a delta pressure sensor to monitor and trigger a regen cycle.

 

Since it does, then producing extra soot shouldn't be a problem. The other problem with producing more soot is it will foul the EGC quickly.

 

More power=more soot=more regen cycles=less fuel economy!

 

Yes, that's the obvious side effect.

 

So program it to bypass the regen cycle and take off the DPF. Done!

 

It's not as easy as that.

 

Why not? Just convince the computer that all is functioning properly, it does not need to regenerate, and remove the particulate filter. Seems like it would work to me. Im no expert though.

 

I can tell you the price one would have to pay for a tune like that is more than it would be worth. Too much data to manipulate compared to yesterdays engines.

 

Well Matt at LIPD as stated several times that he has been working on custom tunes for the 6.4L for some time now and he expects it to take another 2-3 months of work before a successful tune is possible. And yes it is not that simple as to just remove the DPF and tell the computer it is still there, as the computer uses several different sources of information(ie mileage, load on engine, injector fueling ratios/timing, MAF sensor etc) to determine when a regen is neccessary. It just doesn't have one sensor in the DPF that says it is time for a regen, to the best of my understanding of the process.

 

Elite diesel supposedly has a tune finshed and in testing on a 6.4. They also have a set of bigger injects available for the 6.4 and the tunes are supposed to help maximize performance and reduce soot to help keep regen cycles in check.

There IS a switch to shut off the regen circuit. The problem is that a cal with that set off would be strickly a race track cal only, it is not legal to bypass or defeat the emissions systems on vehicles that run on public roads.
