Dyno Results For the M40i

j1980mac · 04-07-2018, 10:13 PM

I was wondering if anyone has actually put an M40i (G01) on the dyno? Would LOVE to see if BMW's advertised 355HP/369TQ ratings are actual WHP/WTQ?

+1

Also, Dyno's with Dinatronics Sport and JB4. Love to see these.

I plan on dynoing mine. It has a JB4 and BMS intake so I will do a few different maps. I just moved to orange county so if anyone has a good 4 wheel dyno in Southern California they use let me know.

On a related note, is there any kind of chip yet for the M40 that can reprogram the engine to get more HP/torque? With my 07 335 I remember it was pretty popular but I haven’t been following much since then, not sure if that’s still a thing.

Yes, the JB4 from Burger tuning. Been around since your 335

Thanks. Their page doesn’t seem to list the G01 as a compatible car. Any idea what the increases are?

Never mind looked up the engine number (B58) and it’s on there. Thanks for the info.

a few people on here have the jb4 along with ssimps, but no one has dyno'd or if they have they did not post up any results...maybe the winter has been harsh everywhere?

Nasty winter. Did you get the snow flurries this morning? I've had a JB4 sitting around for a couple of months for my 435i.

Waiting for the spring thaw to get here.

Was going to go over to EFI logistics close to me to dyno it but the $150.00 charge has me thinking twice.

150 sounds pretty good for a dyno. but I've never paid for one on it's own, had to as a package deal for a ecu flash once...didn't even check the price for a solo run

I can't exactly blame it on the winter. It is just time consuming and relatively expensive. Especially when trying to find a 4 wheel dyno.

It was about a half day ordeal when I dyno'd my 135i and that was without the drive.

I am lucky enough to have 101 octane at a station near me so I have tried maps 1,2,3, and 5. I am contemplating Water/Methanol injection at some point, but as there are so few people doing anything to the G-Chassis cars at this point, I don't really want to be the first person. It is also a hassle keeping the tank full, and putting the tank somewhere etc..

seems like hardly anyone is doing anything to g01 engine wise, b58 already so smooth and shifts are quick, the exhaust tones are nearly perfect (I don't hear the drone unless stereo off, sport mode, on highway by myself), the adaptive suspension allows for sporty feel..depending on rubber/rims the car rides quiet...car is nearly perfect as it stands and I don't see this car as needing lots of changes besides some aesthetic updates and that's just personal preference.

I personally wouldn't tune the engine until longer down the road, anything under 20k miles is still a baby to me. don't blame you for not leading the pack on it all...

buttttttt I'm still open to seeing stock dyno vs tuned dyno results
