How can i tell if my frs is tuned
 

I bought a salvage frs thinking it was stock but it had a lot if aftermarket parts. im not sure if headers and lightweight pulleys can change a cars feel but the frs really feels like its tuned. Its running catless headers with no check engine light. I even checked the codes in the scanner but nothing is appearing. I want to know how to check if my car is tuned and what type of tune is it.

You have some cajones to register a salvage title. If it's running a catless header and not throwing codes, it is most likely tuned.

unless you have some form of system to read ecu then you cannot rearly tell if its tuned.


you need something that at a minimum will read the CVN or checksum value number from ECU and the calibration ID like ZA1JB01C


you can then compare the CVN of a stock rom with the same calid if it same as stock its stock if it not something has been changed in ecu.


then to work out what tune system it is your going to need some more tools.


if it reads with Tactrix/ecuflash or oft then its not a BRZedit tune or its and ecutek tune without racrom features added.


If it wont read with tactrix or oft then it likely its and brzedit or ecutek tune with racrom features.


then you need to try brzedit or ecutek system to see which one it is.







some catless headers have the second 02 sensor in a spacer tube and this can stop or delay the ecu working out its catless header

Ok i figures out that it’s has an ecutek tune because when I hold the cruise control button and it moves between 1 and 2 rpms
But what can I do with this. I don’t have a dongle or cable and I don’t know who put the tune on it. Plus I want to activate the features of ecutek such as launch control which is not on the car right now.

Mine does the same thing but I can’t notice any difference.

Does it feel quick? If 'yes' then no and if 'no' then most likely yes....
