for a second or two without knock

 

There's no reason to see AFRs like that under boost. Ever. You also said "a few seconds."

And "accelerating mildly."

None of these things add up, and none of them make it ok to target 14.6psi at 150kpa.

 

Said no OE turbo car trying to pass strict emissions standards. ever.

 

Not sure if i should rephrase or laugh ruefully at your sad but true comment.

 

All in all I understand I need lean as possible (knock free, normal EGT) cruise with 35-40deg.

Leaner map all around will give better mileage and I can go to 13.5~ in transit boost, WOT would still be 11.5.

I think that's my plan for how to get better (normal) mileage.

Thanks.

 

i dont understand why you can't just tune like this:

 

I understand that tps based and leaner afr map would be very much the same.

Thanks for the map Brain. (I'll try it too)

 

Cruise is not 150kpa though. I never had ridiculous AFRs like that in my map and i broke 30mpg every time.

 

Where did you read that cruise is 150kpa ?

 

<p>This is my 32mpg AFR map.</p><p><img src="https://cimg5.ibsrv.net/gimg/www.miataturbo.net-vbulletin/514x350/80-m5zsnhq_b70eaac4cb2fcbb0dca9afaf407d6af1f80c1fd7.p ng" title="" /><br /><br />&nbsp;</p><p>I have seen @Ben&nbsp;talk about cruising even leaner, with lots of advance.</p>

 

Brain,
Why not carry the 16.0 value to the cells below down to 30 kpa?
