Snow Performance Meth Injection

[Aliendex]

Been wondering if anyone uses the Stage 2 kit with the VC-30 controller from Snow Performance.

They state that it is MAP enabled (0-5V)

From the photos of the kit, it looks like they include a MAP connector which split the signal into the controller.







What MAP sensor do you suggest to use for acquiring the signal? Post-cooler MAP sensor (3.5bar) or the ones in the intake manifold right after the throttle body (2.5bar)?





Left or right side have any difference?

Planning to install the meth-injector in the charge-pipe for now.

I am running TorqByte system on my M6, used the TMAP (3.5) at the beginning but then I switched to the Intake MAP (2.5).

The reason was once you lift your foot the TMAP will overshoot causing it to continue spraying while the throttle is closing.

Bank 1 is the main & all your data logs will be on it

P.S. Couldn't reach to the Intake MAP so I tapped it with Posi-Tap. For the TMAP you can use this

Glad someone cleared my doubts!
That TorqByte looks really neat with lots of features.

Were you able to split the signal of the original MAP 2.5bar sensor without any problem?
Why TorqByte suggest you to split the signal from the 3.5bar TMAP sensor? (13627843531)

The SnowPerformance VC-30 stage 2 kit seems to have a MAP wire splitter included and bundled with the harness.
Or maybe it's just a connector and require to install a new MAP sensor somewhere.

Not sure how i'm going to configure how much pressure relates with the actual voltage of the sensor, they don't give any info.

If the MAP sensor inside the intake is the right way of measuring the pressure, this is where i will read the signal, no doubt on that.

I'm struggling a bit finding the information about the SnowPerformance controller, the web-site is not helping, they don't release any comprehensive schematics or manual.

This is what i have found so far from the snowperformance.net website (to not be confused with snowperformance.eu)








They are even selling the kit with premium taxes for us in Europe lol (+130€)

From what I understand, the car will hold boost when you let off the throttle in sport plus/d3 so you can get on the throttle again without lag. You would be spraying when you shouldnt if you used the prethrottle map sensor. Curious how guys tap the intake map myself.

I followed this link and it was so simple, no problems at all
https://torqbyte.com/blogs/tech/usin...th-the-cm5-lts TorqByte gives you 4 options, drop them an email they are so helpful.




Notice the difference between TMAP and MAP once you lift your foot at this point you need your system to stop spraying.



If you are keen on snowperformance you can add MAP voltage parameter to your data log & calculate.

There is a plastic T holding the wires, you will find one wire loom going to the intake manifold. Remove that tee (Circled in red, it has tabs) look for the wires you need (in my case black and yellow) I used two Posi-taps to hijack the readings.

I'm no more sure about the SnowPerformance
The TorqByte controller looks amazing and easily expandable.
I'm probably going to buy the CM5-LTS controller and the rest of the stuff from other manufacturers.

Thank you for your feedback M6Roar

I have not found any reference in the bmw MAP sensor guide about the intake (2.5bar) sensor, only for the post-cooler (3.5bar)
[My oem MAP sensor number doesn't coincide with any on the TorqByte guide]

Which year is yours? if Realoem showing you this part number 13627599042 then its the same as 13627551429 (Old) / 13627585493 or you can get a photo of the map sensor it self as the part number is written on it (get your phone on a stick and take a photo ) as long as you get the wiring correct that is fine the rest will be calculated by TorqByte software.

In my case I got Aquamist nozzles (they have full system too), BMS pump & Torqbyte controller.

This is Aquamist jet.

good info in this thread.

Wonderful! gotcha

Mine is a 2014 and the P/N is 13627599042 like you said (wasn't sure if it was compatible by looking at the TorqByte guide)

Now is only a matter of building the rest of the system

What size injector do you use?
Are there any pre-compiled data tune for the torqbyte or better starting from scratch?

P.s.: TorqByte.co.uk seems to have some kit pre-made, nice!
No need to scratch my head trying to figure out prices and shipping costs from parts all over the world.

What size injector do you use? I tested a lot of them (DO5, BM5, BM7, Aquamist 0.9,1,1.2)
Are there any pre-compiled data tune for the torqbyte or better starting from scratch? Im using OTS stage2 93 tune from BM3, wasn't planning on tuning for meth. For when to spray and how much I talked to Peter from pureturbos.eu got my controller from them. Wonderful guy and so helpful, Special thanx to Peter

You can get your figures from bootmod to setup your MAP with Torqbyte, I made a calculator in excel that I can share with you if you would like. All you need to do is input the numbers & it give you all ur inputs for torqbyte.
