Mazda RF7J 121 vs 143 maps

[jovanzac]

Hi to all,


My sister in law bought a Mazda 6 2007 GG 2.0 MZR-CD with 121 ps. He wanted to do a remap but i was thinking if it can be tuned to 143 ps like the HP version with just copying the maps.


Can someone tell me: can i copy the maps from 143ps to 121ps ? Are they the same engines but the difference is only in software or ...?


Also is there any real life difference in those two version of the engine ? Is it worth to remap it to 143ps ?


Thank you all in advance!!

Hey. In terms of hardware, the RF7J engines are identical. Turbine, nozzles and so on ... Everything is the same. The difference is still in software.в программном обеспечении.Hey.
