Any engine management system (EMS) that can support multiple maps can have a map for meth and one for no meth. The EMS meth map will not control the meth injection at all. It will only optimize fuel, timing, and boost (some do not control boost) to get the power the meth will allow.

The map will be expecting to see the meth injection and will have increased timing, etc, to take advantage of the added knock protection and octane. Basically, you can just use an off-the-shelf map for the non-meth map unless, for some reason, you plan to run a lot without the meth active. That sort of defeats the purpose of the meth kit though, ya know?

I mean, if you run out of meth, (via your low level indicator, etc, not actually run it dry) just switch to an OTS map until you get more.

Have you read up on the value added by using the controler module(s)? Some would argue that there really isn't much value to them because they aren't able to vary the flow as much as it might seem. For most applications you would just as well off (and cheaper) using a single stage boost controlled system, or even a two stage boost controlled system.
Just my opinion.

I have a meth tune and a non-meth tune on my Cobb Ap. You can see the difference in dyno results in my post 100% meth Alkycontrol pdx tune. S the answer is: Yes!

You really dont need two differnt maps when running METH. You can preset when the kit starts spraying. Mine in set at 10 pounds. For around town driving, and not slamming your foot to the floor it works just fine. It really is all in what you want.

While it's true the maps are identical up to the point of injection, you most certainly do need 2 separate maps if you are tuned for meth and the meth either fails or you run out. If you get into boost at all and the meth isn't there - severe, and terminal detonation is not far behind. Try to moderately pass a car without using more than 10 psi of boost in 5th gear sometime if you don't believe me. In my car, if I breathe on the throttle in 5th or 6th I'm at 13-15 psi before I can even blink, and I'm at 20 psi one blink later. Try that with an AFR of about 16:1 (no meth), and a boatload of timing, and it's buh-bye.


BloDro - just plug it in, and it takes about 12 seconds to flash in whichever map you want. It could not be any simpler.

I do carry my AP around with me, but I have been driving around for twenty days now on my meth map and I haven't even thought about turning off my meth kit. I have no intention of not running meth daily everyday all day- I bought a 55 gallon drum of the stuff. Honestly, I don't know why I carry it with me. I have enough meth in my 12L tank and my spare 1.5 gallon tank and I check the level often enough so I don't really need to- but it is there just in case.....
You definately need to get tuned to take advantage of it- unless you are just misting the smallest amount to give you an extra cushion of safety and not gain any power. I like what tim from PDX did with mine: he protuned me without meth and then he protuned me with meth and gave me both maps! Any tuner should be able to do that- and that is ideal!

Only downside is for people on EcuTEK. It requires the EasyECU software which is like $550. I planned on using my AccessPort, but it crapped out on me.

EcuTEK is what i happen to run... so i guess that is why i have learned to deal with only one map. I really just never let my Container get less than half full. I do agree with you Flycaster!!! It is really hard to pass someone while doing highway speeds and not get into boost hard. I guess i dont really have a choice though.

Yeah, but when you charge by the hour and you have a really good tuner it still probably cost the same as a single tune at other shops.
