Idle timing tables

[1000HP]

I need a few more idle timing tables. In gear and out of gear changes idle timng. We already have one of the tables which is in neutral or park now all I need is the table that controls idle timing under 1 mph in gear. I think there is one for the pilot too. Not for sure yet.

Agreed. I have tried to address this with Ross, to eliminate surging/leaping. Maybe now we can finally fix this.

Without going back over all my LLY stuff, is B0942 - B0944 only functional in P/N?

here is an email I sent way back.

"...Now I am finding that idle timing appears to be fixed. I cannot change it. It appears to be independent of B0910 and B0944.

I finally went and loaded the old stock tun, and I got the same idle timing as all the rest of my attempts (to change it), 2 degrees BTDC (140 F ECT)

Is there perhaps some dependency/trigger I am missing, or that was overlooked? I think it possible to quiet the truck with some retard, but no luck changing it, ...."

It seems to be when you put the truck in gear, neither table is valid. -3 or -4 degrees, until put in gear. Then goes to +2. The advance creates added noise, perhaps the timing change is load related.

Yes,
main injection pulse idle timing b0944 and pilot injection idle timing b0937 both only function in neutral or park. There are three tables I need for both pilot and main injection pulses. We have the ones that function in park and neutral (bo944), (b0937) and we also have the ones that function above 2kmh main injection timing C (b0910) and injection timing after pilot d (b0929).

If i could have the timing tables that come into play in gear stopped or under 2 kmh it would help so much. I want to see lower egts in stop and go traffic conditions and this would help tremendously. The more I play with these 10 hole nozzles, the more I wish I would have stuck with a 7 hole.

Thanks Ross.

I checked just a few minutes ago.....mine does not seem to miss any tables.
Are you sure you are not getting the difference in timing from the higher injection quantity?

[1000HP]

Yes, I am sure!

I had another look today and nothing really stands out , but, it still smells of gasoline inthe office right now.....the smell of Diesel should return soon enough and I'll take a REALLY hard look for this infamous timing table.

I am positive that these tables are there. If you want I can send some logs going from park to drive stopped and then to drive rolling.

Thanks for taking a look at it Ross!

I did some siginificant changes to my idle timing table and as soon as you shift into gear the timing is defined by a different table. Need to do further adjustments to the main timing table to see whether that table is used or not.
