CS is way stronger than ZCP. The extra torque gives a faster time 100-150km/h, topend 5700+ RPM is similar to ZCP, nevertheless it's much faster than ZCP. My best time was 8.0 sec 100-200km/h but otherwise than that, consistent 8.4-8.5 sec while ZCP was 8.8-9.0 sec!
We have a GTS that's consistently 8.5s, ambient temp 20C/68F or so.

Too bad we don't have many GTS dynojet results.

Try to shift around 6900RPM It will do low 8.

I can also confirm this as I have also tested the M4 CS map with a vbox and ran 8.5s.
I never spin the car to 7.5k, no point as power is falling off.
As Halim says shift at 6.5K brings you back into the meat of the torque.


This run was done on a +1% slope with 15% Ethanol.
so its safe to say it will do 8.3-8.4 on flat road

Other variables like oil, water and air temp would alter those times. A little change in engine timing due to a increase in IAT would decrease power.

You have almost nothing constant about the testing.

I'm not a engineer. But I did stay at a Holiday Inn and I watched the movie Titanic. Engineers said it was unsinkable.

Agreed, I said so myself, many variables. But the overall trend is consistent.

BTW, it's the marketing guys that said the Titanic is unsinkable

Is that right? You are hitting 30PSI?

That cant be right?

Its not right, I am measuring absolute pressure, so subtract that from ambient pressure, this is what the MAP sensor sees.

at 5000ft above sea level my ambient is 12.4 or there about, so 30 psi less 12.4 is 17.6psi relative boost or the pressure inside Intake manifold.

check the pic below.
peak boost is 31.14psi less 12.38 ambient = 18.76psi
hope it makes sense.

remember the DME is load based and can vary the boost to meet the load targets needed.

To Be very honest and I know the s55 in all variations are the same short of water injection, but i would love to see a log of a proper M4CS vs one with a manipulated file and see how they compare, even different i-Step levels have changed the cars.

would be interesting but I can attest for sure give the car octane and it
makes a huge difference.
M4CS map on 91 octane runs same boost with allot of timing corrections and lower timing once adapted around 12-13 deg.
same map with 20% ethanol will target nearly 15-16 deg with no timing Correction at all on all cylinders.

We are lucky where I live, we get 94 AKI fuel with 10% ethanol readily available at the pump. That's what I use.

Wish we had that here, they claim it's 100RON with 5% ethanol. But I mean my logs provide something else LOL.

I tried to add E85 and it just cleaned up my timing big time! I didn't get it dynod though but I managed a 6.4-6.6 sec 100-200km/h on the E30 OTS !

Petro Canada 94 is rated at 101.5 RON and 88 MON for a 94 AKI .

Too bad I cannot do data logs to check if it is as good as they claim.

thats damn fast Halim for OTS map.
what is your ambient temp BTW? must be fresh..LOL!
so your cylinder 4 is having no more TC? and you wanted to change out the injector.

I would pay money to see the Stock M4CS map on your octane
pity there is no way to read it, but honestly I daily drive the M4 CS map, love it to bits as it so progressive and smooth.

Thank you!

Well I clearly have no clue wtf I'm looking at.
So to know your max boost psi, you have to monitor both and do the math? That just seems overly complicated for simple boost numbers.

nope just select relative on your dashboard.
and the logging software works it out for you, I have just been using it for a while and gotten used to it this way.

Did you ever try an octane booster like Torco or VP Octanium? I wonder if they really change anything..

Love the BM3 platform for its ease of use and the choice of maps. I've been on stg 2 map and DCT map for more than 6 months and I've had my share of fun.

I have noticed recently, especially with launch control some clutch smell and slip in 1st. I wonder if anyone else using BM3 stg 2 or people with tuned cars of similar hp/trq have seen similar symptoms?

I have tracked the car but always went back to CS map when doing so because I am not sure if the extra power and heat generated by the stg 2 map would be reliable on track.

Looking for other feedback and I guess a word of caution to those running similar setup.

Later

that putting it in dyno mode is a new one to me?....... i wonder how many others have done this before a dyno run....what difference does it make?

We always do it this way, I've experienced on some cars that there was a big difference with and without. 40whp. But didn't test on this, anyways, it's there for a reason
