Disable high Rev cold start

[Ikaros]

I left the idle values the way they were.
I'm using OFT's off the shelf tunes. They're 1400 for one table and around 1200 for the rest. I don't want to mess with those if they're only going to help reduce the noise by a little bit

id change you Idle target tables to be max say 1200 as well

Would you also leave Ingnition timing up a bit for the cold temp?
Is it normal that my Cruise Control also doesnt work anymore? Is it the P050B code diisabled that does that?
and is it safe for our cats since they dont heat up as much, got the second cat only

The post start timing is heavily retarded in stock rune to burn the fuel very late in cycle to create higher exhaust temps to heat up the primary cat in header quickly. This is also what creates a lot of the noise on cold start.

The maf offset adds fuel like a choke on old cars, thats why their still some higher maf offset values at the very start of the wsrmup cycle at very cold temps, these should be suffient for cold starts.

Yes you will definitly need to disavle P050B on Ua and Canada tunes or you will thtow a cel code and cruise will be disabled and maybe other things. This code checks post start ignition timing

Thanks! Just to make sure, Cruise Control won't work when the P050B is disabled from the OFT?

cruise control is disabled when you got CEL (but IIRC is only thing that gets limited from cat readiness check fail). Disabling that check prevents that CEL to pop up.

Well I disabled the code from Oft, I had no CEL but still wasnt able to activate Cruise control, Maybe it was only because it was the 1st drive afther flashing the ecu?

If you dont have the Check engine light illuminated or the slip\trac lights are not on then their is some other problem with cruise control.

Oft onlt reads engine codes so their may be a ckde in one of the other computers in car like vsc or abs computers.

Try removing batt terminal fir a few mjnutes to reset all car computers, see i cruise is working then

Drove the car today (it was the second start up afther the tune) and Cruise Control now work, I suspect that maybe on the 1st start up right afther tuning the car maybe it disable it, Thanks for your help guys!

Also should I run 0 or -4 ingnition Timing and what will be the difference between both and is there more risk with one or the other?

Just 0 or -4 just changes the sound run the one you like best

I can't seem to find the tables...
Are they available on the A00G as well?

Thanks!

What flash device do you have ??
A01G is compatable with A00G.


OFT roms will actually update you to A01G


If you using tactrix just use A01G roms and def and flash A01G rom to your car instead of the A00G.

I am using A00G roms because I thought that would suit my car best. I will use A01G (what the OFT automatically suggested).

To edit my roms, I use RomRaider.
I can't seem to find the MAF correction tables...
Could it be possible that EUDM OFT maps have less features?
Thanks for the quick answer.

I see you are from Belgium. Are you a member of the facebook group GT86/BRZ Owners BeNeLux? Post your question there or PM me. I'll help you in Dutch

To answer your question, you need to update your definitions. Use Wayno's or Kodename47 defs, then you have all of those tables. The one's suplied with the OFT are very old.

OFT A00G ROMs are actually A01G just "re-coded."

The maps don't have any less features, the definitions just determine what tables you can view.
