also send the log to ecutek support attached with your tune
They will help you figuring out more

They already told me I couldn't run the k24 with the BRZ brain.
It seems to run great besides this 85% throttle thing.
I will see what they say.
Thanks for your help

[tomm.brz]

they told me I couldn t flash other regions' calid , what they tell you doesn t matter, they still can help you debugging This or at least try to understand why the fuel cut

[tomm.brz]

but hey first try disabling launch and flatfoot!

Didn vtec enabled with the same custom maps you did on the cpc output? was sufficient the a01g switch?

Yes i used the same maps to operate vtec. I will try that.

well at least someone that finally confirm USDM racerom patch don t work good


Also, just for more integrity, put X axis on the intake cam you did for Vtec as Engine load as the stock table instead of MAP
and move the activation map you did(can t remember maybe Custom Map N? ) before the cam custom map
Ecu reads them in alphabetically order
but I saw you put some deactivation delay so it s probably already ok,
try anyway to put them in correct order just to avoid strange behaviour

yes can confirm racerom 9.1 seemed stable very few bugs. Racerom 10,11,12 quite a few strange bugs especially on 2017+ cars and especialy on non european roms ie usa roms.

With launch turned off and launch retard map off it has ran flawless. Turning to 8400rpm

Now what?

A01G did the same as A01C with the mystery fuel cut with launch and map enabled.

[tomm.brz]

now you can ignore the bug, put accelerator trigger for launch a bit higher
and maybe enable launch only on another map on the cruise lever and then switch over to the stable map

or you do debugging with ecutek support if they are willing to

[solidsnake11]

The fuel cut only happens in lfa 3.
Last log never went in lfa 3

[solidsnake11]

I sent Ecutek an email

Do you think this map could cause it fuel cut.

Boost Target Mode/Gear Limiter

[tomm.brz]

no, that modifies only the target when you have an ebcs
it won t fuel cut ever
Neither boost limit that you already encountered days ago will cut fuel, it s cut accelerator pedal %

This is the reason I asked

[tomm.brz]

it's sketchy as hell , i see what you mean

i think fuel cut is an error from them and they meant throttle closing

Anyway you set boost limit to 4 bar, it shouldn't trigger
Also it fixes by disabling launch, so i guess it was that

[solidsnake11]

Here is my answer from ecutek

That's a little beyond what we normally offer support for, as its well beyond what the software has been designed for.

My only real suggestion would be to check all of the clutch switch wiring etc, there is also a logging parameter for the Clutch Switch that may help you diagnose the cause

Kind Regards

He told me LFA 3 was clutch switch, maybe I'm riding the clutch a little. The clutch switch doesn't show it unless it uses the other switch. It still don't make since why it cuts fuel because its way past the Launch speed. I never had flatfoot enabled.
