Hello all,

This is my first post on the forum, so apologies if I have posted in the wrong place. I am looking to buy a 230i G42 soon, as the M240i is a little too pricey for me, including insurance costs. I'm essentially after a quick(ish), small, RWD coupe, so the 230i ticks all the boxes.

During my research, I've seen that the 230i and 220i of this generation both share the same engine and are only separated by a factory tune. So, my thinking is, couldn't I just purchase a 220i, stage one tune it, and essentially have a 230i for the price of a 220i?

I've asked in other motoring forums I'm in, and no one is entirely sure, so I thought I'd make this account and ask the experts.

Essentially yes. If the ECU is not locked you can remap, otherwise it’s a send away the ECU job = expensive.
Note you will have to declare the mod to your insurance (and noting your location, that’s like going to be expensive). Also, a remap will invalidate any associated warranty.
