Ill have to look at the ecutek roms again, I think I looked at the K00A and K00B Japanese and the auto looked like same old tables no dual fueling power AFR tables etc but maybe it was late :-)

Looks like I'm wrong. I was lead to believe that all MY17 cars had the new fueling but looking at a number of tables in the EU MT and AT, they are the same as previous years, including the Front O2 sensor scaling. The US AT ROM K00D has the new fueling changes, but the JDM one doesn't look like it does.....

Hmmm that weird the USA autos get new fueling strategy, and the Japanese and Europe don't strange

Something to do with Euro5 emissions standard? No upgraded header either IIRC.

Would there be any reason for me to scale MAF settings when running on a catless header/stage 2 OTS tune with stock intake? I had a grimmspeed intake on, took it off, and i'm still getting odd values. i have high LTFT at idle and low RPM's/throttle. I have very random STFT spikes, and command AFR and recorded AFR can differ quite a bit. I've cleaned the MAF sensor but no changes were noticed. any thoughts?

Not sure about the UK, but on the mainland the MY17 has the same engine as the pre facelift, no upgrades either, so it makes sense the ECU is also the same.

Sure. There's more across the board but nothing extraordinary in the dip-area.

The earlier spark is necessary because ethanol burns slower than petrol.

Just found out about this OFT tune. Didn't know it could be flashed to stock and be virtually undetectable by dealer. Nice! Will look into this.

@steve99 As IAM and MAF V logging don't work on my D00G Rom, can I scale my MAF with the other MAF reading(g/s) as this works?

Open Flash Tablet - OFT TIPS Trick’s & FAQ

I still have cat, Evap and oxygen sensors not ready but when I floor it at 6th gear with low revs (very low) the car doesn't go up in speed at all


I tuned it to stage 1 91 yesterday and turned on LC.
