V3 and Meth Injection/O2 Simm/FMIC Capability??

Shiv said something about v3 being able to implement something for meth injection. I have not ordered my kit yet and was wondering what anyone at Vishnu or any official "insiders" think I should buy into. Is v3 going to offer direct meth control? Or is it going to be a simple option to just raise boost a little more?

Also, was wondering, is v3 going to have maps immediately available for O2 simms? Or is this coming in the near future? I am holding off on downpipes until I know v3 will keep me CEL free.

Also are aftermarket FMICs going to run well with meth injection and DPs as well? Is v3 going to provide for this from the minute it is released or somewhere down the road? Just trying to check my p's and q's to avoid boost spikes.

Thank for any info you guys can provide.

We'll have documentation for 3rd party meth systems soon. Just wrapping up other details right now in time for Bimmerfest

What type of meth system are you guys using? This is what I am most interested in. If you could elaborate even a litte, that would be great. Thank you for responding though!

Buy any 3rd party meth system you feel works the best for you. We'll just enable the leanrun protection, overboost protection and adjust the AFR targets for meth use. The ECU will do the rest. Unless the jet clogs at which time you will have an expensive paper weight under your hood. Be careful.

Thanks, just shot you a PM about it, but thanks for the info. Do you know what the boost limits would be when set for meth use? Are you going to have an option for meth/race gas combo? What would the boost look like for those bad boys?

Would you recommend Stage 1 Boost Cooler or Stage 2 Boost Cooler from Snow Performance? Stage 1 just injects a fixed amount of spray once boost hits a certain PSI. Stage 2 starts injecting at a certain PSI, but then increases injection amounts as the PSI increases. Any thoughts on which is better and why?

To tell the truth, I can't even recommend any meth kit right now. I haven't tried it myself to see how the engine responds. I'm sure it will respond great and effectively solve the fuel system limitation problem as well as help a ton with charge cooling. It's just what happens when it runs out (or the jet clogs) that scares me. Perhaps we'll just need to stick with a small jet and only use it for minor enrichment/cooling. Instead of doing it Evo-style and dumping it in there in copious amounts!

Thank you for your honesty. I will be trying out the meth kit as well as V3(already have v2 and love it). If you somehow need me to datalog or jump on as a meth system beta tester, I am game. In your opinnion, would you go with a fixed amount of spray at all PSI in a general PSI range i.e. 6 - 14 psi? Or would you go a PSI based system that would respond such as 60% injection @ 6 PSI and 100% injection at 14 PSI?

I guess you would also have to take into account the fact that boost tapers at higher RPMs as well and the cooling would surely be needed up top as well. If you could just throw your 2 cents one way or the other, I would appreciate it and return it with my thanks of datalogging, etc. Of course you could ship me one of those v3 kits early so we could get some logs done, etc.

Yeah, first you copy my catchcan idea, now this!

I guess great minds think alike. I was going to go with a NOS sprayed intercooler, but decided against it in favor of meth. The v3 opportunities seem to be great with this.

I hope shiv lets me know which system I should get so I can get to work on it .

There is a flow transducer unit mated to a solenoid that can effectively protect from clogged jets and running out. Solenoid could be used on either the wastegate lines or diverter lines to immediately stop boost.

Will you be outputting a signal from the procede though?

I think he is just going to make a juiced up map for it. At least that is what I gather.

I'm hoping not, I know it's probably easier for him to make an output then the map itself so I don't see why he wouldn't now that he's decided to do it. Plus if he plans on doing it to solve the fueling issue there's no choice but to make an output.


Looking forward to it though. This is something that track guys could REALLY benefit from.

Or people looking to push 400whp. Sucks now that BMW is cracking down. I would be royally pissed if I had to get my meth kit uninstalled for some uncalled for issue such as fuel pump, etc.
