Dyno comparison Gen4 vs Gen3

[bmwbadboy]

Bold Red / Red - Gen4 + Full Akra + OEM ECU

Bold Blue / Blue - Gen3 + Full Akra + RS2E mapped ECU

Gen4 makes 198bhp vs 189bhp, also torque in 6-8k rpm range is higher by 20.

Surprisingly fueling is pretty good in OEM map, looks like it's adapting itself very good (lambda sensors are in-use)

Canny see the graph bud

 

[oldwobbler]

Its definitely there

Can see it and it's nice and strong. Less weight, more power...gonna fly.

interesting, my gen 1 with full akra and map is 198 too

On a dyno at HM ?

The Gen1 was a screamer. Made great peak power. But BMW have been adding torque consistently since then.

 

[Schuey]

I can't see the graph?

Reposting to see if it helps

 

[Schuey]

Amazed at the level of extra torque even against a mapped Gen 3!

 

[alex]

Yeah ShiftCam makes a noticeable difference. You can see that linear power build up which led to people thinking it wasn't doing anything at low revs.

I know it’s all pretty irrelevant given the differences between dynos but my Gen 4 made 199hp completely standard when I had it on the dyno

yep there is plenty hardly ever use it all on the road (or track)

I was overtaken on back straight at Sepang by Gen4. I wish I had that extra torque and power.

I guess you were on a well sorted Gen 3, any idea what the Gen 4 had had done?

Well...

Gen4 was with Full Akra, and it turns out it has very good fueling out of the box (bottom graph).

But in reality it was likely me being too late on gas as I was still learning the track.

To be fair, thanks to short gearing I was ahead first few seconds

Look at all that lovely mid range torque! There's a huge amount of extra push where it can be used. It will make the bike so much more relaxing to ride.

[QUOTE Here's mine but showing before system and after.
I got fed up of looking at one then the other.
Nice to see similar results on different dyno's.
I'm going back mid Feb where I think he want's to do something on the throttle side of things.
