Idle timing tables

[killerbee]

..., so far the typical numbers from 0°C to 62°C are 8.0 or 9.0 deg ...

I have not seen anything that high...strange

Could be due to the fact that my injection quantity especially when cold is a lot higher than it would be on #2!
Right after startup I see up to 70mm² just to maintain idle!!
Even need to adjust several limiting tables just to get the engine to rev !

hmmm, ok. That sounds like an interesting tune!

Lennart, make your bio-diesel from Taco bell left overs, not left over oil from Gedadschde.

I am not running BioDiesel, I am running canola oil AS IT IS!
I go straight from step 1 to step 14.

Here is the BioDiesel Process:

hey guys just for another with timing, i am having a low stop/brake apply, to brake off barely rolling stumble, it is tune related but i have been monitoring timing at idle and once warm always have -5 main timing. no where in my tables can i find why this is. my main inj timing is set for -3.2 at that range but still i see -5. not sure why. but i have to do the same thing at a drive thru.

I touched on this in my first post. Ross has found one of the tables (B0950) Not sure What this one controls yet nothing affected in my logs by this table yet. Here is the breakdown of what I have figured out.

B0908, B909, B910, B0926-B0929, in factory form are all used above 3.13%TPS(B0938), 1MPH(B0939), 975RPM(B0940). B0938-B0940 are the change over points that control what tables are used when the truck is in gear, rolling or stopped. We still need the tables that control timing for pilot and main in gear stopped which are controlled or switched over by B0938-B0940. B0942-B0944 Control timing in P/N. I think B0950 Is a start up table for lower engine operating temps.

Hope this helps Ross.

Thanks

I have played with B0590 in hopes it would be "the" table but so far I have not been able to find its use either.

Lennart,

If you want to have total control temorarily until we find another solution, you can fill in the value 0 for B0938-B0940. Then you only have to adjust absolute timing values from B0908, B909, B910, B0926-B0929 and B0942-B0944. This works. I have been runing this patch tuning for a while.

I haven't seen any resolution posts on this -5deg idle timing. Does anyone have a clue? Looks like it is based on temperature going from a positive number of around 4.0 to 5.0 deg at 87 deg F at startup to the negative number when above the mid 160degF range and only in gear.
