Electric Power Steering coding options?
I've been having my m235i for about half a year, the steering just doesn't quite right compare to my previous e92.
I found this thread, and thinking the m235i or m240i could be coded the same way as the base m2? (<2018) with better EPS (F87 M2 CS) https://f87.bimmerpost.com/forums/sh....php?t=1541527 Anyone knows? |

Finally ppl are looking in coding steering feel. I've read that the m240i got a revised eps module part # but the rack in the same. Many claim that the m240i steering is heavier than the m235i. Perhaps it's possible to install the new module and program that to work. The M2 has a completely different rack.

Matrix hunter is correct. Ive been doing extensive research into this. I absolutely cannot stand the 1/2 dead space that is apparent in the steering of the m240i. according to realoem.com....the m235i/240i is straight electric steering, not electric power steering. The m2 is electric power assist steering. The f22 is listed as AT-steering box ELE and the F8x is listed as Electric Power Steering Rack. It might be possible to recode the f22s to increase or decrease weight but i think the ultimate issue with the steering is with the dead space, I've installed a stress bar, it helped but still dead space, installed m2 control arms, helped but still dead space, installed turner motor sport monorail thrust arms, helped but still dead space. I do not notice their being a weight difference between the f22 and the f87 or f82, just a difference in how the f87/f82 has no dead space where the f22 it is completely apparent in. I believe that this is the "weight" difference feel everyone is describing.
for reference here is the link to the straight pipes review of the m240i. just watch the first 5 mins and they'll explain the steering.

I was curious about this and you can see used steering racks on ebay with columns, so I'm not sure what those codes mean on realoem, but I doubt it's straight electric steering- it's electric power assisted steering. |

Its just not good. I hate it so much i got rid of the car. I’ve driven infinty q50 or some big luxury sedan and as much as i dislike that steering also, i disliked the driving experience more in the m240i than i did in that infinity. I bought an m4 just to get away from the 240. It’s disappointing, because the motor is great, it looks good, but the steering is just awful. The m240i was my 4th bmw and the steering drove me away from it.

Looking at realoem the F22's have a different rack (32106889112) than the F87/F80's (32107852660). Both electrically assisted. I know the F22 rack is belt driven from the electric motor. |

Why not just bite the bullet and get yourself a nice, well-maintained e36 or e46. I think you'll drive yrself crazy and spend a ton of $$ trying to get a modern car to feel like something with direct, unassisted steering (and it still won't really replicate it).

Lastly, there are no BMWs with drive-by wire steering. The M235/M240 have the same electric assist steering design as the M2/3/4. The difference with those cars are they have more performance oriented suspensions, alignments, more chassis supports, and wider tires. It all makes for a more lively feel.

The "dead zone" that some may have is likely due to a need for the EPS start-up function to be run with ISTA/D to re-learn the straight ahead position and rack limits and calibrate the torque sensor in the rack, especially after any alignment work or suspension component change has happened or after pothole impact that has changed the alignment.
I don't have any dead zone on my 2017 M240i, the only effect that causes any wandering or change in feel around the straight ahead position in my car is due to the tyres tramlining on rutted roads. |

M235 rack https://www.ebay.com/i/202538159392?chn=ps M2/3/4 rack https://www.ebay.com/itm/Steering-Ge...-/303111426812 To say that the M235/240 have terrible feeling steering is rather bonkers. Sure, there are many professional reviews out there that say it lacks feel (same is said for the later model M cars), but the majority say it's some of the best overall steering from BMW in a long time (same said for the M2 obviously). When I got my M235, I sure didn't think to myself, "OMG this steering is so terrible!!!". I honestly don't know what all the fuss is about. Yeah, there are lots of cars out there with dismal electric steering, but the M235/240 isn't one of them. I hustle my M235 a lot and push it hard. Never once have I felt that I needed more feel from the front end to understand what it's doing. Maybe my opinion would change if I routinely tracked the car, but for B road driving, steering feel isn't high on the complaints list.

Don't forget, BMW intended to make this model compliant for all. It'll never be perfect for anyone except for the average "Joe". We as enthusiasts notice this right away, but nothing a few bushings, performance alignment and an LSD won't fix.
Took my buddy with an M3 CS for a ride the other day, he says my car is noticeably more "raw" and loved the way the car felt through the twisties. Just a matter of perspective and willingness to venture further to obtain the "feel". All I know is, is that there performance baked into this chassis, which is worth a fraction of what we paid

I could get a used N55 M2, but I think I'm pretty damn happy with the sporty/luxury of my MW with red interior M235. I'm CONSTANTLY asked if it's an M2, probably because the my wheels look similar and MW makes the fenders look larger. With all that said, I do enjoy driving a more raw car. Right now I'm trying to decide if I'll do a NB Miata and turbo it (like my buddies) or if I'll get a fewer Miata RF. Either one will have full suspension, tires, and alignment for track duty and tolerable for sub-200 miles trips.
