Are you worried about EGT?


You're fine with lambda 1 part throttle.


You don't control EGTs with boost control.


I still haven't figured out what your original thinking was.  There is so much consistently wrong with what you're saying I'm having trouble keeping up :/

None of that makes any sense. If you want best torque, it makes the most sense to only enrich wot so your mileage doesn't suck everywhere else. If you want part throttle to make more power for a given pedal position, adjust kfped or kfmirl.

If you want safe, you're either talking EGT or knock. It can't be knock, its freaking E85.

So what is it? You just seem to be making up stuff randomly as you go.

First you say:

Then you say:

What do you mean by "want"? Or "stable", for that matter?

Look, you clearly want to learn about tuning. To that extent, part of tuning is understanding exactly what you are trying to accomplish. If you can't explain something, it generally means you don't understand it. If you're just going to make changes based on hunches and feelings, you're not doing yourself (or anyone else, if they are reading this and want to learn) any favors.

I know of no reason why running richer than lambda 1 should help misfires (or you are down on torque for other reasons), if that is what you are experiencing. Just going rich to "fix" it is hiding other issues, IMO


That isn't how ME7 works, that isn't how any tuner works. They drive by numbers FIRST (i.e. they understand everything that is going on before making guesses), then by feel. You don't get to drive by "feel" until you fully understand exactly what it is you are trying to accomplish, and you've exhausted every other (objective) option.


Which is why I am asking YOU questions: so the next person actually thinks about their problems in a objective, meaningful way, and not because they read some voodoo on some forum someplace.


Look, I'm only trying to be helpful. If you can't see that your methodology has issues I don't know what to say. You need to properly explain the root cause of the instability you are seeing at lambda 1 before even considering your options.

Now you might say, "by adding fuel, I can try to narrow down the reasons why I'm seeing the problem" - that's fine.

But "hey I added fuel, and it is better, I have no idea why - there I fixed it" is not good tuning methodology.

If you expect to succeed at tuning, you really have to be able to drill down and figure out what is really happening, and not just guessing then moving on.

If you had a long track record of success, I'd say sure, everyone has their own way of doing things, but as long as you are LEARNING, this method will get you nowhere in the long run.

Not only that, but if you have a long track record of success, if you can't explain WHY something works, it helps no one; it just leads to more random voodoo bs you see on every given board on any given day.

Exactly and read my post then.. i said im going to do a more detailed log today. And suck now my flash tool is broken aswell. But i can still log actual vs requested. If the deviation is to big I will try to look into what to do. Will be intressting.

Timing could be an issue as i mentioned... Im starting to suspect something like ignition after reading some more about E85 flame speed att diffrent loads.

Stay tuned for another digi fun movie

Umm, if you want 0 overlap, why not just change the VVT mapping instead of disconnecting your hall sensor??
