BRZ 86 FRS ECU Information - ECU Type Flashing Learning Resetting

[ap5512]

Hey @steve99 - got a few questions after reading your post.

So I just installed the OFH and flashed it with the Stage 2 93 OCT UEL tune. I noticed it the car being sluggish and having to push the gas pedal down further to get it going (pedal dead spot??). My question is:

1.) Should I be worried?
2.) I know the ECU needs to learn the trims and other parameters so is it just a matter of time before the pedal comes back to normal? (Also - what's the approximate timeline for the ECU to fully learn everything?)
3.) Lastly, should I just reflash/reset the ECU and do the tutorial on quick learning or just wait it out?

Thank you.

Just do the method to speed up the learning the next time you get in the car, it doesn't need to be done only directly after a flash.

Thank you.

as per @Kodename47 said , no use reflashing ecu will learn throttle calibration after a few drive cycles.

@steve99 after flash my ecu from stock. At the end of the process my tablet showing "an error accoured while writing to the ECU, please try again" message. But then I check my ECU information it showing the file is stg2 eul. I'm a newbie so help me out.
Thank you.

Error message like that not a good sign. If the car starts and runs then appears flash completed. Before flash starts ecu is erased.

Did you folow the prompts on oft re key on off ect, also key on means full on not just accessory ie two pushes of start button, but do not start or key to full on position.

The ecu info only shows the last file oft tried to flash, it does not actually read that info from ecu, all it can read is the calibration id and its same for tuned or non tuned rom.

Did you modify the tune files with romraider ?

Does the realtime logging via oft work ?

Car run perfect with no CEL.
I do click the prompt and it's keep telling please wait and after that prompt option appear again. I click it until the error message pop up.
I do flash it with 2 click on push start.

looks like it was just a glitch, make sure cable plugged into oft and obd port is pushed in all the way.

couple prong look like deeper that the rest.. is this normal ?

Hello,
Looking to see if anyone is having a flash issue on a 2015 BRZ limited. I installed the Vortech SC and flashed with a Perrin tune using Ecutek and now it would seem the ECU will not come out of programming mode. I've tried disconnecting the battery and have gone through many adjusted maps, Perrin has been very helpful with the maps, have the newest Ecutek software and the problem persists. Even flashing back to the stock tune the ECU won't come out of programming mode if that is the issue! There is also a laundry list of other things that don't work now. My car starts but in limp mode because of codes UO122 and UO131, both show in duplicate and they don't go away. So all that works right now on my car is the engine, headlights, door lock on fob, and dome light. PLEASE HELP! Thank you!

What calibration ID have you flashed? As you have a 2015 (MT?) you should be running a ZA1JD00C I would reckon. It may be that you have been given an older version which are incompatible with later models.

[SDP]

Yes, MT and ZA1JD00C
The flash happens, the ECU isn't turning on all the other ECM's and such.

Is that the original ECU cal ID too? Symptoms all point to a mismatched ROM type. The D00 files aren't backward compatible and vice versa.

How do you mean it won't come out of programming mode? Does it not state flash complete? Do you clear all DTCs in the final writing stage?

[SDP]

It is the original as far as I know. It says flash complete and 1 dtc read, I clear it and after that it shows 5 dtc' cleared and shows as follows:
UO122
UO131
UO100
UO122
UO131
And says they cleared. But if I run a dtc check only UO100 cleared. As far as not coming out of programming mode...from what I've read that when you flash the ECU, it turns off all other ECM's and such, which it has done, problem is it doesn't turn them back on after I'm done! May just need to be something Perrin and I work with Ecutek to figure out.
