Brz doesn't like to idle

No. why should a dyno fix it?

you need to force-upgrade to euro tune. Or downgrade to very old and not so good for turbo, racerom 9. No other way. that means you need to do a full retune with a reliable guy. I m one of it or like Zach at CSG should be aware of this

[tomm.brz]

i mean, if this tuner with a dyno then put on a US tune again, the bug will still be there, and probably will just not notice/ignore it and you are at starting point, with less money

Many tuners don t even know how to force upgrade our car

Also your idle and stalling problems are exacerbated by your super huge injectors, other that they seem unnecessary ( i don t use E85 but i use since 3 years stock 228cc injectors with 1.05 bar of boost) they can t inject precisely or short enough for 100% Pi idle

People with stock injectors tend to notice less this bug because it doesn t stall with stock injectors, it just runs shitty and they ignore it thinking it s all good

Crystal clear explanation. What a damn shame! This is precisely why I haven't yet touched my stock ROM. I feel like I would have to approach your level of understanding before fiddling with it. I deal with fully documented systems all day long. I think that if people really understood the nature of this kind of reverse-engineering, there wouldn't be so much blind trust. There are MANY areas still known only by the original authors.

Tables are relatively easy to find and manipulate. Functional relations? Nested dependencies? Blah blah blah... Nope. No way.

but they did a good job at ecutek, with plenty. of defined tables, a bit more than those from open source 's guys.

The real limitations come out when you try something exotic with custom maps, some things like accelerator modification through them can easily break things and trigger a dangerous limp mode with unresponsive pedal for example... or in this case the racerom patch that doesnt work perfectly with US tunes because obviously, when they ported the patch from initial euro tunes to the rest of the world that has actually some differences in the Ecu logic, something was off and somehow it hasn t gotten fixed yet...
they have no complete control over the oem tunes, that s right

still, the fact they filled empty spaces on it with A LOT of new non original tables and 16 new separated custom maps that work so well with the oem tables in most situations is great

When I've learned to reliably get back to full stock. I dunno, man. Fucking black boxes, goddammit. *shakes fist*

same here, I didn't face any idle issue with my car
