2013+ ignition fuse and pump turn on q's

First off, 2013+ owners that have installed the LMS/Alky kit - which fuse are you using that is ignition on only? I know 2010-2012 use 46. I found 70 which operates some of the same things that 46 did in the other years and I am getting power still when turned off and in accessory. When I shut my car off the meth pump kicks on and the red light is on for priming then it finally turns off after about 10 sec. Weird.

Other than that it's working fine.  I do have another question about pump priming...

I do not have a tune but I wanted to try the kit out and make sure it was working properly. I took a 50 mile drive on the interstate and set the controller on 2. When I was driving with cruise on even the slightest incline in the road that would put a load on the engine the red priming light would come on. Should it be coming on this early? Even driving without cruise on the interstate I would have to baby it up hills to keep the priming light from coming on.
I verified the settings inside the controller and they matched others.

I had about 2 quarts of 50/50 meth in the tank and ended up between driving a total of 60 miles with it on and spraying to test in the garage it used it all.

... And yes I will be getting tuned for the meth when I get my turbos on :-)

Thanks in advance for the info!

You need to watch boost to adjust the turn on should start priming at about 5psi of boost and go green at 8psi. As finding appropriate  circuit to power the system I would disconnect until you figure that out. You risk hydro locking your engine.
Pump shouldn't be priming, you say you don't have a tune, so I assume your not running a bar 3 MAP sensor. The calibrations made inside controller are probably set up for a bar 3 MAP.
For me and my 2011 I can not run my meth system with my bar 2 and no tune. Meth pump will will do exact same thing except mine goes green. And have hydro locked.
 
Ok, makes sense if it's setup for a 3 bar. I have it turned off today. I just wanted to run it some to make sure everything was working. I'll just go ahead and pull the fuse in the engine compartment too until I get it turned.

At least the engine should be clean with all that meth ran through yesterday! It never got bogged down to the point of hydro locking but when testing the system at idle it started missing some until I brought up the revs and burned it all out.

I have a CEL I need to check today I think it's from the car thinking it had a misfire.

When test or just purging the system, I turn the knob on controller all the way up and raise rpms up about 3k and hold test button until light goes green. If you didn't order a check valve I high recommend, in the hotter months your meth boils at about 130 degrees this will keep meth in line from pushing out and flooding engine and losing prime. Its about $20 and mount right behind spray nozzle.
 
70 still had power after turning the vehicle off. I hooked it up just to test everything out. I'm heading up to Livernois to tune in a few weeks so I just left it unhooked and I'll ask them when I get up there.

I know there are a few guys on here with 2013s running meth. I would have thought someone would see this and open their fuse box to tell which ones it's in.

I'm probably not going to LMS soon from Portland Or. I guess I can just figure it out with a test light
 
Starting to see why a simple fuse is a mystery. Haven't been in a hurry seems how I didn't have the meth tune until now. I know I can just test and find the one I want to use, but I thought I'd call LMS and see if they could tell me. They couldn't or wouldn't. They did say some pretty conflicting stuff against my limited understanding of the alky controls.  Here's a couple / they absolutely use both the GM and the motorcraft 3bars / they absolutely never tap into the factory 3bar. And there was a lot more said. I have no idea if there tune will even work and no confidence I might add.

The meth system when install is said and done was super simple. I think there is only 3 wires that hook up to the car (besides grounds). What's the stinken mystery. 3 wires come on, am I missing something here, besides all the wires that interconnect the meth system to itself there is - hot to battery - trigger to fuse - map to PAC

It might all work fine as is, but after talking with the gentlemen from LMS I have no idea
 
I suspect it follows as a kind of disclaimer... like the tunes order page.  While I'm in no way saying meth is bad or dangerous... this product likely has significant product liability and they want to keep ins rates down....

Seems like an odd comment, when there's been plenty of people who have been running their meth tune confidently, and consistently, for several thousands of miles with no I'll effects.

Well as long as one doesn't consider a big 'ol Cheshire cat like permagrin plastered across one's face as an I'll effect.

Lol.

Yea,  just to be clear... they won't help because they feel they can't without being responsible (for anything that happens)... it's like mos of the price of a Cessna is product liability insurance cost.
... clearly meth is a relatively quick 40-60 WHP.  No warning or opinion other than as I'm trying to clarify here intended

Just as clearly... the tunes are proven and do work.  Have fun!
 
I believe Livernois has atleast installed the kit on a few member's vehicles. Hopefully those owners can chime in.

I believe basically everyone else has tapped into the factory sensor, ran power from the main fuse box wire, and used a fuse for a turn on source. That's it. 

The tune should still work fine. As long as the settings in the Alky control box are turning it on at the right boost level that the tune it wanting.

I was under the impression the only reason why it came with that GM 3 bar was due to it being a universal kit from the get go.

I don't think it's not they don't want to help, the sales guys don't do the installs so they don't know. All test light will find your answer a lot quicker.

Good point, if the sales guy looks at what comes in he kit and the instructions he's going to say it all gets hooked up and they don't tap into anything if he doesn't have any actual experience putting one on a SHO.

Thanks guys for all the help. With your help, Julio's and all the tech write up's I felt that the install came out nice and clean. All the parts fit just like the pictures, the pump and hoses mounted and routed just like bpd's I also put a ss/clamp around pump and mount. ALL the wires are inside a new harness and wrapped with tape all the way from the pump to the glove box (wrapping seemed to take forever). When I pulled the wires through the fire wall and ran to the PAC behind the g/box it was already in one nice package, then sealed the hole around the new harness with a catalyzed type silicone

Now I already assumed LMS would not support or counsel on a on a meth install that was not purchased from them, but I just asked about the trigger fuse. I guess the fuse location is part of there own privet knowlage base and if they didn't want to give it to me, I can understand that. My last question for them was, this is what I did / this is what I've got, will the tune I have work or can you tune for it. His response left me more worried then ever. "I don't know, maybe, if you want to blow your car up" so that's where I'm at
Last thing - I think I was talking to the shop not sales

Yikes. I wonder what they'll say to me when I show up week after next with mine!

They will say "Your an idiot" just kidding
I know they have had some nightmares with cars in the shop that have had meth kits installed buy the customers, so I'm assuming there already thinking " oh G what did they do" . I wish I could go in but it's a little far from Oregon
 
If everything is hooked up correctly, there is no reason it won't or with there tune.
And if you don't have things wired correctly there tune will still work as long as you have a bar 3 map. Your car will run fine.
Another words the worst thing that could happen is you blow a fuse, your car will still run just as it did before.
You need to get your trigger wire hooked up and test meth system. You don't need a tune to purge the system or to see if you get a green light.
And once you achieve this, all you will have to do at most once you do get a tune for is maybe adjust the turn on.

Thanks. I'll do like you say. Seems like I should be good to go. I tried to run the 3bar before the tune and dang, the car sure didn't like that (tranny clunk / engine sputter). I'm assuming the tune corrects the vehicle for the use of the 3bar
