I am just wonder who adjusts their tune for E10 gas, and most importantly how do you do it??

 

I do.
My tuner said that sioch is around 14.12. So he changed table B3601 to 14.12

I can't remeber what else we changed.

 

I can look at my tune if you need something specific. I'm using my phone so I can't post the tune

 

i know what settings to adjust in the tune itself, sorry my real question is how to adjust it... My real question is do i need to redo all my airmass tables using lambda PIDs instead of the AFR PIDs...

 

I do in every tune that I setup especially locally and if not local I try and get as much info as possible about the fuel sold in the area and as far as how well their really is only one correct way to do it and that is to change the afr value in the stoichiometric table, everything else should not need to be touched as long as injector data is good and the airflow tables have been done right. The PE enrichment values also stay the same as well.


Hey Black Rado I see in your sig that you had James tune your truck, very good choice he knows very well what he is doing and does it right!

 

Hey BlackGMC, using Lambda is an excellent way to approach tuning with our ethanol blended fuels these days, it really can simplify things. I have been tuning thinking in terms of Lambda for quite sometime now and it sure does clear up alot of confusion and overthinking with afr's.

 

Yes I'm very happy with my tune.

We talked a lot about tuning and I learned a good bit from him.

So the only thing that would be changed is the table I was talking about?

 

So i use an LC1 with a analog gauge that reads AFR, is that now pointless???

 

Yes sir just a change in the stoichiometric value will take care of it.

 

also since all my airmass tables were adjusted by the correction of commanded versus actual AFR, all of that will need to be redone using eqratio vs lambda?
