does the JDM 7RA have a rear o2 sensor,

Can the maps for fuel and ignition be copied from the 7 RA map straight to a 7 GSR rom and uploaded without any problems running? i have looked at the xml's the addresses for each entity seems to be the same except some sub adresses such as RPM are different in the two xml's.

I basically want a rom to upload to the Stock 7GSR to provide some performance difference.

any help would be awesome,
thanks in advance.

I think none of the 7s have a second lambda sensor...
But it would be a very bad idea to upload the file of one vehicle to another.

Did tried to flash 7RA to my 7GSR (JDM), CEL is on. Did Scantech turn out the rear O2 is not detected... you can still run with CEL, but I suggest you stick with 7GSR ROM and tune it with dyno.

My best result with tuned 7GSR is 31kg torque with 268whp.

thanks for that, the main thing i wanted to check was the CEL light, which was from the O2 sensor.

salex, thanks for that aswell, will get a wideband installed this weekend and have a go myself.

You should be able to copy the maps themselves, but as stated above it's not advisable to flash the whole ROM. The Ralliart ROM is not that special, much better to tweak you exising ROM, you'll have much more fun and learn a lot in the process.
