Google has failed me, need help with fuel cut ecutek
 

Car runs great everywhere except if I stab it from 50% to 100% throttle in the mid rpm range.

that s vague description of a problem. does it knock or what? it bogs?
i dont even really remember the whole parts of your frankenbuild, which injectors commanded by PI do you have?

Goes lean and Flat on its face. Everwhere else it runs great. 1050 injectors. If i go slower with the throttle it does fine.

I looked at the logs closer and its fuel cut?
6040rpm at 3.04 g/rev
90% throttle and 0 ms fuel

I have no idea
could you post the entire log?
if you want link me your current tune, maybe I see something off looking at it

k24log
3rd hump is the cut

k24-1050port-ls3direct-3barbosch.bin


I think I'm ready to switch to A01G.
I used a custom map to drop timing in launch, before it would not keep the timing down, when it reached the low threshold it would go back to the base timing of 29.

yeah well that is just how launch control by ecutek works, it also fuel cuts intermittently so if you want something more extreme you have to custom set it anyway
I ll take a look at your things


for next time please upload to datazap as I m on handy all day and it s stressing to upload with it

Without the custom map pulling timing on launch 0psi boost at 4000rpms
With custom map 9lbs of boost at 4000rpms


let me know if the links are not open to the public. Its first time I have used google drive.

ok,
tune is ok but there is a bug , probably because you patched it with Racerom 12

i had problems with rr12 too, not exactly this, anyway
LFA state changed to a different value, and accelerator is over 85% (that s trigger for launch and flat as standard value) exactly when some sort of fuel hard cut entered, LFA means LaunchFlatfootAutoblip, it s a debug code for ecutek support
It just seems a weird random bug

Delete racerom12, put rr11.1 ,.... if it cuts again, try disabling launch control
if it cuts again, switch to A01G or A02G with rr11.1

Thank you so much for your time. I just loaded A01G with rr12, I will go back to rr11.1.

can you log again with a01g?
also, can you log your launch control just a couple seconds, no need to actually launch

It did it again with A01G and rr11.1. lfa3 when it cut then it went to lfa5

A01G RR11.1

weird
did you try disabling any extra features?

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

Not yet it just happened minutes ago.

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

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

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.

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

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

I sent Ecutek an email

Do you think this map could cause it fuel cut.

Boost Target Mode/Gear Limiter

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
Attachment 188727

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

Here is my answer from ecutek

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.

i hate them when they do like that
they don't even state what LFA values mean
it s obvious to me it s a failure in the launch control, maybe triggered by some of the many hacks uou did to make everything work
Don t know man, try maybe as i told you, use multiple maps for launch control, you can switch map any time also while driving or accelerating

and honestly i can t wait for a video of a WOT


Did you as them about LFA? what 3 and 5 specifically mean

Lfa3 was clutch and actually I think it is the clutch switch i rest my foot on the clutch, its enough to activate the switch, 1 is on and 0 is off so the log shows clutch was applied. I'm trying to come up with a longer throw switch.

then 5 must be launch active, used to trigger your custom map for launch timing for example, Great thanks
