Talking Re map ecu

Hello every one, i m new to mini cooper. i just bought a mini cooper s r53 year of build 2004 with 45000 kh on the clock and allready start the mods... i put a kavs 15% pulley and thinking of changing the fuel injectors as well. i notice that a remap of ecu is nesecary for that mod... can you please tell me more on this section please like how i do the remap is it really nesecary and all i have to now.
is there any other mod to do after i change the sc pulley?
the injectors that i found is bosch 550
ps sorry for my engilish...

If you go with larger injectors you will need to map for it otherwise you will be putting in too much fuel (the car will think it still has 330cc afterall) so the map needs to be done to scale the injectors appropriately.

Personally, I would leave the injectors until further along your modding journey - do you have any other mods besides the pulley? if not, you can add a dave.f air intake, exhaust manifold (JCM / Janspeed etc), intercooler perhaps a new cat back... I would try to work it so that you can fit a new camshaft at the same time as the bigger injectors and then tune for the job lot

RMW in the states can do remote tuning, not sure if lohen or P-Torque can do this or not.

In summary and IMO - leave the injectors for now and fit the above mods instead. If you can get a set of JCW injectors you could get a JCW map flash to keep you going (not sure how great a solution this is tbh) but if you have bigger plans I would wait and do it a little further down the line.

The injectors can be noisy and will tick but if its only on first start and goes after a little while then yes I would say it could be your hydraulic lifters.

Had mine change - does it sound like mine in my video?
