timing base(A) tables are seldom used in an LMM engine. modify the (B) tables.
in edit, you know how to change and use the (A) timing tables

my guess is an EGR problem. some engines need a blocker plate and some do not. an EGR blocker might be helpful in your engine.

THEFERMANATOR is correct. Dual tank settings will not fix your problem. Even identical OS numbers is not a guarantee that every thing such as fuel level will work correctly. EFILive will compare...

Good thread. Can't remember hardly any open discussion about timing/tuning. Sorry, but I must throw another variable into the discussion. That variable is rate of fuel delivery.

Using the...

Have you ever reduced the air and experienced knock in a Diesel? I'll do this a a final check of the timing.

Have you ever tried cutting the duration in half and leaving the timing the same? ...

Timing needs to vary with amount of fuel. There is little curve to your timing table. I've seen pilot tables that are similar to this. Small amount of fuel can take a while to burn because of...

Seems that two sensors are used to determine position. The combination of sensors varies depending on if the engine is at idle or not at idle. Thinking that both crank and cam position sensors are...

My attachment for you was not an engine program.

The attachment was to be used in EFI Live scan V7.5 and is used to monitor or record engine data. The ability to monitor or record data is vital...

Made a few changes.

Let me know if this is helpful.

Can you log engine data yet? Attaching a set of useful engine tuning PID's

Save your stock file and maybe even e-mail file to yourself. Make a change to stock file and then program PCM with...

Things changed.

I used to be a Diesel god 10 to 15 years ago. Now, no one knows but most important no one wants to share their information. I will most likely never make any money from tuning...

Finally logged TCC pressure data

Increasing the TCC solenoid duty cycle is not useful in raising the pressure to the TCC. Increased duty cycle did not increase the pressure. Decreasing the duty...

I looked at log

did some math

found that clutch pressure muliplied by TCC Maximum gives TCC Commanded pressure

I have been told that changing TCC Maximum is a no no but can't understand why....

My OS is 25836826

If possible, I'll try a full scan. Any advice in doing a full read of the TCM would be appreciated.

How did you log tcc slip?
I believe that tcm OS is in my 08 and I'll post a stock version for you.

Found a simple program with DPF delete for an LMM.

Took me a while to find that the only difference in my truck and friends was 1 kpa of pressure between front and rear of the DPF. The tubes to his sensor had been removed. Over time, dirt and dust...

First scan to see if there is any difference in pressure before starting.

My friend was satisfied with the temporary fix.

Too soon to suggest buying or modifying differential pressure sensor.

Found that any difference in pressure between the front and the rear of the DPF will cause this. Needs to be zero differential pressure before start up. Sometimes, dirt enters the pressure sensors...

Again, this is just my opinion...

I did a very similar thing. Made a tune a little too strong and felt that the truck was spinning wheels when it was not spinning wheels. Or felt shudder in the...

rechecked data log

72.6 PSI was maximum at 2508 RPM

3030 us main duration(not active) but post injection #2 was active
3030 us pilot #1 duration(not active) but post injection #1 active
3030...

3000 micro-sec pulse width at 3000 rpm means a duration of 54 degree. Saw duration similar to that on a stock lml engine pulling a hay trailer with 82 PSI boost.

One day I'm going to make an...

Your second level has enough fuel duration to slip a stock TCC on my truck.

Remember, this is only my opinion and based on my truck and programming.

Didn't look any further than that. ...

How many percent over stock did you increase duration at high rpm and load?

Here is what I've found.

A stock engine with a clean fuel filter/strainer is sometimes straining to achieve stock...

Too much duration at low fuel settings. Many people only add duration at higher fuel settings. Injector on time is sometimes increased by mistake at low fuel settings without reducing the rate of...
