I have stock air intake and evo 3 exhaust.

That's normal from what I've seen. I don't think anyone will have a fix other than to raise your idle speed. With our OTS maps, idle targets are already 100rpm higher than stock.

Thank Shiv for the answer.... it happens once in a while not all the time.

Hi guys,
We just OFT tuned an FRS equipped with a TQ250 Phantom electric supercharger. Pretty darn good results. Check out our Facebook page

Any chance of posting it here for those of us that don't use Facebook?

Incredible results on e85 with headroom for more (header, TQ300, etc.). DAYAM!

Awesome! I've been following the electric supercharger thread and just purchased an OFT yesterday. Great to know that the phantom s/c will be supported once it is released.

Anyone running the OTS maps at 4500ft or higher elevation?

anyone have a basic tutorial for how to run the tuning software. i understand the mechanics of what does what on the engine and most if not all the parameters to watch but never could figure out ecuflash. hoping this will be better.

* just ordered the tablet and nameless DP about 5 minutes ago (Christmas for me)

I can suggest a potential fix - raising the overrun fueling RPM thresholds 100-200 RPMs higher - in other words, having the injectors kick back on from overrun fueling a tad earlier. Otherwise the idle stability tables can be used.

I don't think these are defined for the OFT yet, but they are in the Romraider definitions I put together:

The switch on is already quite high stock (1300 RPM, compared to an STI for example at 900), but worth a try.

Otherwise, I can take you through the idle stability tables.

+1 for the above. i was able to eliminate this issue (for the most part) in my tune by adjusting the idle stability tables. brzedit doesn't have half of the tables defined that romraider does or i'd try the overrun trick.

For everyone's edification, this is what the idle stability tables look like (the table is a MAP related modification to the targeted idle airflow):

I aim to please

I'll PM Shiv the relevant addresses so he can pass on to the programmers.

Td-d · 11-28-2013, 12:26 PM

Can you add tables in BRZedit? If so I can just post up the addresses?

brn12345 · 11-28-2013, 01:09 PM

Just flashed the 1.34 stage one on my J rom and all I can say is I am very pleased. Much nicer to drive and the soft rev limit is cool. No more face in steering. Also the quicker warm up mapping is much appreciated. The early morning loud drone is much minimized. Thanks Shiv!!!!!!!!

i wish. only the 'pro' version can edit the defs, i only have personal. personal doesn't seem to get any of the updates that the pro version gets either. would've been nice to know ahead of time...

i can't wait for logging on the open source side so i can switch back over.

so brzedit doesn't allow saving tune in bin format?
maybe you could do your tuning in RR and then load the tune in BRZEdit (diff and copy if needed from your current one whatever you missed)? I remember they posted that they made this feature (loading OFT tunes which is just a bin format) available for personal version?
