+1.

I sprayed over 1000cc at 11psi on my 2.0L four cylinder car (less displacement to spread the meth out vs. our 3.0L 6's..) without a progressive controller and you couldn't feel a thing. No bogging, hesitation, etc.

I think a lot of that is contributed to the small turbo I used, similarly the two small turbos the N54 uses. The time between 11psi and 18psi is negligible, especially with a 6 speed transmission. If we were talking about old school muscle using a 2 speed powerglide where you spend a lot of time in one gear building boost, etc, it might make a difference.

I'm all for technology, but I'm just laughing if someone is telling me there is a benefit to progressive meth. The cost doesnt outweigh the fairy tail benefits.

I'm happy this topic can stay focused and as least defensive/offensive as possible.

Ahhh...see your point. Engine doesn't bog down when u spray so soon.

I wasn't jabbing. I am truly interested as I am constantly impressed with the timing logs I see for people running meth.

Strongly considering a setup for my car but am still under warranty.

Would need a kit that is easily removable.

Seeing as I keep things so simple, I remove the meth, intake,charge-pipe, Bov and revert back to stock in less then 1.5 hrs... comfortably. I could probably rush that to an hour or less if need be.

Meth is 2 wires, meth line, tank and pump Probably an Hour. Wires and Line are ran underneath the car for simplicity.

DCI, a few minutes, and charge pipe is another 15- 20 min.

Then of course the tune would be removed but thats fairly easy maybe 20 min.

Moreover, last time I went in for service, I simply removed the meth tank, left the pump and everything in, just tucked the wires and meth line, wrapped in wire loom/electrical tape, they never knew.

Something to think about...

Yes....I was thinking of a trunk mount kit and purchasing a dedicated charge pipe with a meth bung so that you just swap the entire pipe for the stock one when the time comes.

Keeps it clean and simple.

I just wasn't sure how progressive mapping worked and I also need to consider failsafe features.

Does yours automatically switch to a lower map when meth flow stops.

I am not sure how that whole feature of the Procede wires in to the meth kit.

With the labonte fail-safe (which i dont run), you simply feed the meth line in and out, and wire that into procede (somehow)...

From the settings in procede you would then select optimum flow 1-99 (something like 14 is popular idk)

As long as your flow meets or exceeds that number it will keep you on map 2... otherwise map 1 if its not met.

People that have this fail-safe can tell you more, the info is out there.

Again, no failsafe, so I play with the devil a little.

Wiring in a labonte is probably another 20 minutes of time, if you can keep things clean and organized.

I always recommend a 2nd charge pipe for ease.

the "injection mode" 0-99 is actually the figure you see at 100% meth flow on Debug Byte 7 when logging. The DO7 nozzle + solenoid will usually flow 13-14, so you would set the flow number at 13-14. If you have say a DO10 nozzle which flows 17-18 on a solenoid, you would set the injection mode to 17 or 18. 99 is used for nitrous.

So once I install the kit.....I set the injection mode in the procede user menu to a number that is appropriate for my nozzle size - OK got that.

But what is debug 7 actually showing you on the datalog?

meth flow from the labonte IFS-30 unit... or coolingmist CMGS if that's what you got.

If you have a coolingmist unit, the 0-5v reading is different. I believe Yandy has this setup and he's around 23 on a DO10 nozzle.

Yes, I realize Debug 7 is meth flow, but what do the units mean? Is it litres per minute or gallons per hour or.....?

Just get a meth elbow for quick removal. I really think the elbow is a better place to spray then further up in the charge pipe.

That's a good question actually. It used to be "1" = 100ml, but it has since been revised to something that I honestly do not know. The advice you will get from Vishnu will be log Debug Byte 7 and use that figure.

+1 elbow location works great for both IAT drop and ignition timing.

Ok.....that's what I thought.

It's just a relative scale of comparison then.

So the injection mode user input value determines the onset of flow, and debug 7 just gives a relative datalog index of how much flow......I guess.

That's a good starting point for me so thanks for clarifying guys.

[335xiRT1]

So after you set this all up, using the labonte fail safe if the meth stops flowing, the PROcede will go to map1????

That is the other option I was considering as many claim there is more time for atomization to develop.

Slight problem with that idea is that i believe one of the stock clamps has to be cut off in order to splice in the meth elbow, so might be evident if replaced by a T-clamp when reverting back to stock.......or have I got that wrong?

No you're right but BMW would have to be having an extra special day for them to catch that. You assume the techs even know what the proper clamp looks like I would think as long as the clamp you use is not fluorescent yellow you are good

Meth is an amazing mod. You really should go for it!

if the meth flows below the set point it will go to map 1, but yes.

[335xiRT1]

Ok. Thanks.

just answered one of my own questions from above.

Taken from the Vishnu site:

"Now you can log methanol flow! This is represented by Debug Byte 7 in your datalog menu. Methanol flow is displayed in units of 1000ml/min. So a logged value of 0.8 equals 800ml/min of methanol flow."

Myst was only off by one zero...

Helps to do your own research sometimes!

Like I said that's the old flow reading. The new reading is different. You don't really think you're flowing 14,000ml /min with a reading of 14 do you?

Lol....good point!

I haven't had time to sit and tihnk things through yet, so thanks for that.

I am just doing my research at this point.

I like to have all the details and understand what is supposed to be happening before I embark on a new project .

Meth is looking better and better.
