Logging MUT06 I see the timing that jumps up and down at idle. This make the idle a little rough
I add MUT33, and it show very stable timing, so this timing fluctuation is a continue correction.
Screenshot attached.
Has anyone noticed the same thing?

 

correct me if Im wrong, but I believe MUT 06 logs what the car is actually doing, and MUT33 shows whats in your map. I believe the fluctuations are from the EGR Ign Adv. I zeroed out the EGR advance map and my idle is more stable...

 

I hadn't tought at the EGR advance, I'll try tomorrow!
Thanks

 

Timing adjust during idle to keep a steady engine speed. In that log I see large corrections and the engine speed still isn't rock steady. My guess is that you are running an aftermarket injector that doesn't work well at low pulsewidths.

 

The EGR Valve is not open during idle or WOT. It would have no effects on idle to remove timing from the EGR map unless its part of some other subroutine that I dont understand.

My idle is pretty lopey with the BF 272s and my idle timing does jump around alot. I wouldnt be too concerned with it. There is a idle timing sensitivity table that has been discovered. Its in an idle tuning help thread.

 

Correct

The rest... not so much.

 

In fact I have disabled EGR via FAA bit 11, but nothing changes in timing at idle
I'm going to search about ths idle timing sensitivity table.
0xDEAD, I work with many standalone that have an idle adjust timing table, but I cannot imagine that also the stock lancer ecu have a table like this.

Ah, I forget, the injectors are 720cc denso and I have scaled them perfectly! I am satisfacted with the idle, it is at 1000+-50rpm, I am only courious about this timing fluctuation.

 

my bad! just tryin to help. Im still learning...

 

That is nothing for timing fluctuation. My car goes from 4-20 at idle. I would post a log that I have if I knew how to change the format since you cant post a .csv file.
