Disable high Rev cold start - Page 7 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Ok, I've added to all roms on my Github repository:

https://github.com/TD-D/SubaruDefs/t.../RomRaider/ecu

Remember, if you are downloading from here, make sure that you click on "raw" to get the actual XML (otherwise you will download an html page!)

I've made all rows the same using the lower ones as a template.

so you have all rows reading 8, 7, 7, 5, 5, etc?

Not at this stage - but if there's anything specific you want, let me know.

yes this definitely made a difference, now im not afraid to start my car at 5 am lol. thanks. im runing all tables the same in the maf correction after start, 1400 rpm target idle, and reduced to -8 timing in the post start table. its a pretty significant change.

If this is a reference (initial estimated maf reading used for fueling right after it catches) then it would not make sense for this table to affect the cold start beyond the first second or so of the cold start.

If, on the other hand, it is a maf target table used during cold start then it makes perfect sense and I would assume the ecu adjusts throttle plate angle to get the desired air flow. On 21*C cold start i see 18 - 19 g/s during the high idle cold start.

I'll dig into the logic but I don't believe it's a reference - that was already available as the post start airflow reference and the load reference tables.

It's definitely an adder to MAF.

My car never idles over 900 rpm even if under 10F overnight. I'm hopefully about to buy BRZ edit, perhaps I could send my bin for those more familiar with these cars to compar (mine is a fall 2012 dealer flash.)

You won't have these tables in BRZedit (yet, I'm sure they'll get copied soon enough

)

Yup, I've implemented across all roms. Yours is probably ZA1JA00C.
