One or two make no difference. It might wander +/- 8 or 10 right when you stop!
It will settle back down.
We only care about the STFT in the very first minute or two after you first re-flash. After that, it is not germane to the discussion.
We can shift our attention to LTFT after a few drive cycles, but a few points one way or the other ar meaningless.
We just want to address fuel trims that are +/-12 or worse.

 

people seem to be asking the same question repeatedly about the fuel trims. Maybe a FAQ is in order.

 

Abso-f-ing-lutely. I'll get on it.

Sounds like a great idea.

 

Check the first post.

 

MM: Off your FAQ on the first page you state: You should be seeing high 13's in some conditions, mid 13's in most conditions and high 12's in others.

you should state these most likey would be under heavier load/throttle, as from what I've gathered in this thread that above 14 is what the AF will be at low or light loads or cruising conditions.

 

Jeff...

sent you some followup data on the 1b series maps after running it a few weeks now. I think its running where it should be, but i'll let you decide...

figured some longer term data could benefit the community and your tunes -shrug-

 

It says at high load.

 

I did a search for Cali maps, but didn't find anything on this thread about it...is Cobb or MM providing maps for shitty SoCal gas??

 

yes, Jeff is providing them. I received mine last week

 

Actually, ALL of my tunes are based on crappy gas!
The California calibrations have to do with CARB imposed differences on the '05 and up RX-8s.

 

You live in Cali?

 

Running Shell vPower 92 octane in Washington State

 

my shell V-Power is 93 octane

 

are the stage 3 tunes going to be too aggressive for 91 octane gas in Cali?

 

 

is the "reset ECU" function on the AP the same as unplugging the battery from the car for a night?

 

Yeah, except for the fact you lose all of your radio presets and have to reset your clock.

 

i see...hmm should i be using that function to reset my ECU after every flash?

 

What for??

 

Oh crap, sorry about that man, I was half awake when I read that.

 

earlier in this thread i believe i read something saying that the ECU relearns better after its been reset. i think zoom44 said it.

 

No, Phoenix.
But we get the same crap gasoline.

Possibly. You would be safer on race gas. East-coasters might be OK with the 93 that they get.


When you re-flash, the same stuff gets reset automatically.
