Awesome! Thanks for your quick reply Terry! and thanks for the info Stoolz, much appreciated!

On my F series with just JB4 for tuning, the stage2 turbo is doing just fine. Even 20+ psi levels

EGUIMARMED · 03-10-2015, 08:14 PM

Terry, can you help me To Go To the next level ON my M135 2014 with meth kit cm14, donwpipe, lfpf walbro 255, jb4 Stage 2 with all harness, and vtt stage 2 turbo. Now, this car is running ok 20psi ON E30. We pretend Go above 20 psi, To improve cvs. We have tmap 3.5 bar. We saw the pure Stage 2 running 24psi. Where we find a firmware To run with this tmap To reach this 24 psi ON F séries? Thanks

Dear Terry,
I hope you are fine.

I'd like to know our opinion about this 135i E Series 98 octanes with VTT Stage 2 (no Cobb suport). The car is fast and stable, I think it could be much better. Do you recommend to replace the CM10 for a CM14 and increase boost?
Find attached a video with a some test.

Regards,
Juan Testa

Your questions will not be answered here. You need to post in the support section.

Juan Testa · 04-04-2015, 07:47 AM

Ok, man. I'm not good at e-fora!

Hey Terry will DME that have been updated by the dealer still be flashable? I have a 2011 that has been updated unfortunately so I don't know if Cobb AP will still be compatible. Or is my only way of finding out to throw downthe money for a Cobb and load it up?

I think so. I think all of the 135s can be flashed. Even later 2012 ones. Search around though to verify.

Stoolz · 04-04-2015, 11:41 PM

Updated dme for 2011 model will almost definitely by ok.

Hey was wondering, I am running map 5 on
2010(11) 135 N55 DCT with:

NO METH
Intake
Intercooler
ER ********
CPE Charge pipe
JB4 iso 5.5 with flex fuel
BMS Back End Cobb Flash
N20 tmap
Pure inlet pipe
OCC
BMS Oil Tstat
Fuel it S2 lpfp
E55 mix
VTT DBB S2
LSD/invos

Have posted logs , AFR didn't read properly but all else looked good.

Car is running awesome.

Can I try map 6 with the exact same settings as page 1 on dyno and log results or is meth needed for that set up.

Cheers in advance.

Anthony.

I have a very similar set up and have run up to 21psi (from 3500-7000rpm) on e50 no meth.
I run into issues with intermittent false misfires above 19psi though, so have backed it down.

Stoolz · 04-07-2015, 09:11 PM

Thanks Nugs,

I have Romano Performance looking into dyno tuning for me. Nobody in this country seems to work on these cars.

Heading to Willowbank raceway tonight, hoping for some good runs.

Nugs · 04-08-2015, 01:23 AM

No problem, my advice would be to gradually increase boost and monitor logs closely.
Hope you have better luck than I've had.

Stoolz · 04-08-2015, 05:41 AM

Ok only beat my previous 1/4 mile time by .25 / 5mph with s2turbo,inlet pipe, s2 lpfp, bef, n20 tmap and lots more E85.( I calculate E55 )

Only got 4 runs in cos the place was packed, crap 60 ft and my GF was sitting in the passenger seat so I probably could have run a couple tenths quicker. Car seemed to run strong..

FF was set originally at 100 and has crept up to 118

Maybe my logs from 2 of the runs tell a story?

Foacad · 04-08-2015, 05:47 AM

5mph is a decent increase.

What were the details? Not just .25 and 5 mph.

Out of curiosity what times did you run?

Stoolz · 04-08-2015, 06:14 AM

12.44 at 116.97 mph 60 ft 2.21 sec me 90kg passenger 60kg

Your log look decent. I think you should trap higher with stage2. I trapped 119 with stage1 @ high 11's. Need to test stage2 now when it heats up outside. Been plagued with lack of grip.

VTT stage 2 vs. Pure stage 2.

Yeah, I've been thinking that since the Pure release also, I nearly didn't install it and was going to use it as garden art but I thought I'd give everyone a bit more information. I now just need some input on how to milk every bit of power out of it.

You should definitely be running higher trap speed and lower times. I ran the exact same times with the exact same 60ft on my VTT stage 1

Yeah, I was a little disappointed...

Doesn't look like map 5 is optimizing your performance for that high octane and larger turbo. I'd setup a map 6 like this one and log that.
