End result does not matter if you do not have a baseline to follow.

I'll try to get an S55 with stage 2 93 octane on our dyno and post the results!

Halim can you run stock tune, stage 1 and then stage 2 on the same car etc like a complete comparison

it appears that stage 1 is making 510 bhp ish and stage2 is 535 ish?? doesnt seem like a big step up between the 2 but i guess there is mid range gains that arent seen in power figures

be great to see

I think there’s a glitch with the top speed limiter removal option on this version, as my car stopped accelerating at 170~ indicated. As far as I can tell my GTS roar works though!

I am now using bm3 ots together with JB4 ... good results also

That means I need to find a stock M4, everyone around me have at least downpipes

I made a huge post about this last year I think it was, but maps have improved over time so I might have to redo it

[Smee]

Just do stock map on car with downpipes

Then stage 1 and stage 2

That way we can see same car same setup what the difference is

Also are you planning releases / updates soon. Was speaking to Dzenan about having the flaps closed in 7th gear

I love the idea of the flaps closing in 7th

hard to believe a stock bmw stage 1 is over 500 wheel, dyno reads high

[dr. ill]

Not sure if this is the same version... Says V9.1 at 1:52
All dynos read differently, but he compared it to his baseline dyno numbers

[TrueNorthM5]

Yea, I'd expect MORE than 460 but LESS than 500 to the wheels on stage 1 93.

I haven't dyno'd my car but gained 8-10MPH in trap speed, so I think pretty safe to say I picked up in the neighborhood of 60-80 to the wheels on a OTS stage 1 93 octane

[Smee]

so he made 490bhp stock??? and then 540bhp tuned... adding the 15% drive train loss he keeps mentioning??

seem very high if you ask me

[TrueNorthM5]

I think with a modern transmission , carbon fiber driveshaft....you'd probably looking at 10% loss on that particular dyno (no wheel/tire losses on that dyno configuration). So maybe 464hp stock 510hp tuned, crank.

As with all dyno testing, it's really only the delta between the two that matters, and in this case, I would have expected more than a 50hp delta.

when you flash back to stock does the car need to complete any learning??? lets be honest that car was running stage 1 he flashed stock and tested and then flashed back to stage 1.... surely there has to be some learning involved and thus that original figure could be high??

I am not certain about that. They also swapped intakes out (back to stock for the baseline runs), so there could be some adaptive fuel learning that needs to take place - I'm not sure!
