OK.. so forgive me here. What does this mean??lol

Hi Shiv, for the preloaded OFT's being shipped out this week, how "up-to-date" are the preloaded files in there? Would it come with the latest 1.53b release?

Yep. We will always load the newest release before shipping OFTs.

1.53b works for me meow. Thanks Shiv

Hi Shiv,

A01G works for me now thanks :thanks:

Hi Shiv!

Just tried 1.53b to write, but "write" button is grey.
Will send you my original ROM shortly.
Please take a look what is wrong in my case.
Thank you in advance,

Andrey A00G.

Ecutek have written extra bits of data into the "stock" rom in areas that are just padding or spare space ie ""FF".

This may be for various reasons, but likely to be so that ecutek can identify the ROM as one of theirs for licensing/locking tune ect or that Ecutek has written to this ROM/vehicle at some stage.

Ecutek can also add extra features to their ROM's (RaceROM's (not this one as its a "stock" ROM), to do this they patch the original ROM's instruction code with extra code (program instructions) to perform extra functions such a map switching. this extra code need's to be inserted in "spare" or unused spade in the ROM usually this will be filled with "FF". The extra code data for alternate maps ect is usually inserted in this unused space. These ROM's are also locked/encrypted such that an ECUTEK licence is required to access/flash the ROM's I believe not even dealers can access/flash ecutek locked ROM's

Well that the way i think it works anyway. :D

That's great news for me!

Any more details as to what some of those trim/timing changes etc. are relative to 1.42b?

I'm interesting in knowing a little bit about what adjustments are made and why, for learning purposes! If you'd rather PM to keep it more private, that's okay too!

Easiest way is to datalog and compare the results:

Stage 1 1.42b

Stage 1 1.52b

Not the same stretch of road, but more or less the same conditions and the same tank of gas.

You should be good to go now with the v1.54 download. I updated the stock A00G file with your original ROM :)

Cheers,
Shiv

OpenFlash Manager reports my CAL ID as ZA1JA00C. However, plugging in the OFT into my car and going into Tuning -> ECU Info reports my 'Calibration Code' as ZA1JA01C, while going into Information from the main menu reports 'File in ECU' as a ZA1JA00C bin. I'll send you my stock file to take a look at.

That's totally fine. Your original ROM is indeed an ZA1JA00C. However, when updating your ROM with the new v1.5 maps, your ROM will be updated to A01C.

Thanks for the super quick reply. In that case, any idea why Write would still be grayed out?
