I'm still trying to nail down the exactities around it, who is actually doing the tuning of it etc. Also the possibility of getting a custom dyno tune with it as well.
We'll see, either way more options are better. The only info i was able to extract on date is "soon" some bugs to work out and the car sounds pretty rough at the moment.

If it's tokyomotorsport then it would be the same old, which is....
Agreed with the rest.

we are almost ready with our basemapping for the KW kit, car runs very good allready and has some big grunt lolz, but we need the upgrade map sensor to go any further as it it now leaning out over about 400grams of boost.

we are using romraider + OFT

KW supercharger system
SARD equal length decat manifold
SARD catpipe
Milltek catback
Mishimoto low temp thermostat

Does anybody have the Honda part number for the upgrade denso map sensor?

It's not an upgraded map sensor you need but rather a larger diameter MAF housing (like in the Vortech kit). And then recalibrated the MAF table

I have a 2013 Limited BRZ and was wondering if any of you guys w/ push to start have problems starting your car after the flash? I'm just running the stage one flash

we are using stock MAF on the kraftwerks intake pipe, and rescaled maf with the help of long and short trim rescaling. max MAF at 5V is now at 324.16g/s
does that sound about right?

Is the diameter of the KW pipe bigger than the diameter of the stock MAF housing?

[ST-A]

have to check to be sure but it looks like it. the KW pipe is same size as throttle body

Yep have one of those no problems yet.

Follow direction on OFT (or flash software) after flash is completed turn car completely off.

Then turn on (don't touch accelerator),wait about 20 sec, should start straight up, let it idle for a minute or two (no throttle), then your good to go.

if your LTFT are large it might be worth scaling MAF, shortens up fuel trim learning process after flash or reset also get smoother drive and AFR closer to those set in OL Fuel tables.

My cars been flashed for awhile. It just started out of no where recently. My guess is it might just be my switch

[unsurety]

So will there ever be a BPB, E85, UEL/EH tune in the works? Or do you guys just run the stage 2 map?

Unlikely shiv said somewhere that BPB and E85 don't play well.

BPB move the powerband lower in the rpm range and E85 produces its best power above the rpm range where BPB work best, so it was counter productive.

Same deal for BPB and forced induction eg electric SC

just flashed my 13 limited brz with the stage 1 rom. drove the car easy for a few miles to get the car to learn a bit. gave it a good 3rd gear pull and the power is very smooth. it may just be me or the car hasnt fully learned but it doesnt seem like the vvl doesnt kick in as hard. ill try to get some logs today. what exacly needs to be logged? thanks
