OFT users with ZA1J700C and ZA1J900C ROMs - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Hi guys,
We are in the process of sorting out Advance Multiplier logging for these early USDM ROM types. One person has reported that Adv Mult stays at 0 (i.e., doesn't log correctly). While another has reported (and just sent me a log) of it logging correctly (i.e. displaying a value between 0 and 1.0).

Could I have some more feedback from others with these ROM types? Just need to know the following:

1) What is your ROM type (ZA1J700C or ZA1J900C)
2) What does your Advance Multiplier value right after a write process (it is either going to be 1.0 or 0.0)

That's it! Feedback would be greatly appreciated. I know most users have newer ROM types (ZA1JA00C and ZA1JA01C) so I'm probably not going to get too many responses

I am also aware that many non-USDM ROMs do not currently log Adv Mult either. And this will be addressed after we address this issue in USDM cars

Cheers,
shiv

Mine 700c started at 1, but I think you knew that 8)
Thanks again!

ZA1J700C
Starts at 1

I actually posted a log up of a run right after I updated to the 1.34 ROM here: http://www.datazap.me/u/cnk/oft-134-tune-11-24-2013?1

Nothing crazy, just a cruise to check out the logging feature when it was released. You can see the IAM is 1 across the entire run.

I'm the guy have problems logging the Advance multiplier with the stock ROM. To answer the two questions:

1) ZA1J700C
2) I don't know, I haven't written anything to the ECU. I simply initiated the OFT, did a read, and tried datalogging the Stock ROM values. In this scenario Advanced multipier is always 0.

You will be able to log Adv Mult when you load one of our OTS maps.
