Hey guys, just bought a 2016 Z06 with some bolt ons so I'm looking for some assistance in identifying some things. Next to the hud button there's a silver button that I'm assuming has to do with the meth injection. But not very familiar with methanol so if someone can confirm or deny this for me that would be greatly appreciated. Also, on the topic of methanol, how do I figure out what kind of mix to use? And is there a way to get my wiper fluid reservoir back? Lol it's my daily so that'd be nice. Thanks again

 

My meth system doesn't have any buttons with it. It's a controller mounted on the bottom right side of my dash with a switch to turn it on or off and a **** to adjust how fast the meth comes on. That could be an on/off button, but it's hard to determine from just the information provided.

As for what kind/bled of meth to use I would recommend talking to the previous owner/builder of the car if that's possible. I run 100% M1 methanol in mine. There are tanks designed to fit in the cubby on the driver side of the trunk so that you can retain the windshield washer reservoir functionality. I daily my Z06 and there have only been a couple of times that I really missed being able to use the washer function, to me it's worth the trade off to not have meth inside the car.

 

Nitrous button just like Fast and the Furious.

My meth control has a set of controls, but the only one I use regularly is the test button. Before hits I use it to see if my meth light comes on and is spraying. That's the only use I can see that button having for a meth system. If your car uses it for fueling it's not something you want to be toggling on and off I'd imagine.

None of my friends who use meth mix it. I didn't know it was something people did because that sounds like a hassle. Just straight M1 into the reservoir.
There is a way to get the wiper fluid reservoir back. The guy who built my car said there is another you can buy to make up for the meth kit. I daily mine as well, but haven't missed it at all.

 

Very much appreciate the informative responses. I've reached out to the car lot I got the car from in hopes that they'll forward my info to the previous owner to get some more info on the car. I'll post some pics of it tomorrow, it's got 650 to the wheels so I wouldn't be surprised if the previous owner is on here.

 

It’s more than likely to prime the meth pump.
Ive never primed mine with a switch or button. My builder/tuner knows how I drive 😎 I’ll give it enough gas to get it into light boost to prime and all is good. I don’t even know where my **** is. Ok I do ... it’s somewhere under the dash.
Not many mix only use straight meth.
Windshield washer fluid back again ... you’ll need to upgrade to another tank most are located in rear cubby hole

 

Thanks for the in depth response. A primer button makes sense, as does using straight meth. Being new to methanol injection makes it hard to distinguish between what's most common and tried and true. Learning by the day!

 

We were all new to it at some point. I'm going to guess that the meth is being used for additional fuel and not just for a cooling effect. If it were only being used for it's cool properties then a mix of meth and water wouldn't be a bad thing and you could likely use (I believe) the blue wiper fluid from most parts stores. That's what my neighbor uses for the meth injection on his BMW 335d that's running meth. Since it's most likely being used to supplement the fuel system, I would say 100% M1 meth is the way to go.

I hope you get a chance to speak to the previous owner and get a good history of the car and where the work was performed.

 

Hey guys, quick update. The car lot I bought from somehow has no way to contact the previous owner. That's weird to me but regardless I can't get ahold of him. I'll post some pics here and maybe I'll make a separate thread trying to see if anyone recognizes the car. Also, there's a small blue dash light that I haven't seen before. Is this something to do with the meth kit? I thought maybe it was a low level indicator, but I put M1 in it today and it's still on. Maybe I need more. Thanks again for the help

 

If it's in the washer fluid tank you can fill it to max. There is an indicator that'll let you know if your wiper fluid(meth) is low. The blue light could mean literally anything. At the very least it could just telling you it's on. Either way we can throw infinite guesses but you we won't know unless you pull that dash apart and see where the wiring leads to.

Also bad play for the seller to not have info on the car. If it's not under warranty doubly bad. Should get the car looked at by a shop at least.

 

I wasn't sure if there was something commonly associated with this blue light, but I don't think I need to know enough to start pulling the dash apart lol. I have an appointment with a local shop to have a full inspection of the car so we'll see what they can tell me. Thanks for helping clear things up for me 👍

 

I would start with pushing that button from the first picture and see if that blue light turns off. That could be the indicator light that the meth system is turned on, and there is a good chance that it will change color once the meth is actually being sprayed. My system has a red light on the control that indicates the system is on, then there is a red indicator light that will light up once the car starts to build boost, and it turns green once it starts spraying meth, this is also the point at which I usually lose traction......

 

Have you tried reaching up behind that area? Would guess they installed the switch there because it is accessible.

 

Your position is frustrating, I’m sorry your not having a better experience with your Z.
The good news is: it sounds like you may have the bones for a badass.

As mentioned earlier, I would also make the assumption that the button is for meth & blue light is “ system activated”. The button is most likely the “tester primer” button.
Do you have any after market gauges ? I’m asking because you can monitor either wide band AFR or possibly IAT.
( air fuel ratio, intake air temps). This is useful to help determine IF your meth is spraying. In this case we are attempting trial & error to determine what the button & light are representing. There is a more crude way to do this as well, simply press the button and monitor any changes.
NOTE OF CAUTION: Meth is fuel, adding fuel when it is not needed ( like when we are playing with buttons that we don’t know what they are for) can hydro lock a motor. You can avoid this by cruising at at least 2k rpm. Do not press the button when the engine is not running or at idle. You risk loading it up with too much fuel.

take a cruise or sit in the driveway, get the rpm up to at 2,200 rpm….. press the button:
- watch for blue light to react, change color etc..
- listen for motor to slightly sputter “ get fat” with fuel.
- ONLY HOLD THE BUTTON FOR A FEW SECONDS after this occurs.
If the above happens you can make the assumption that you are spraying while pressing the button.
If you have gauges, watch for the IATs to drop or AFR to show rich.

Can you share some of the mods ? If you have meth …. you obviously have other mods that created the need for additional fuel & or cooling. This can determine if you need 100% or 50/50. I don’t know many ZO6 folks that have added a meth system without other mods that caused the need for additional fuel. So I would stay with 100% to be on the safe side.
At least:
- pulleys ( upper & lower)
- CAI
- headers
- tune ( for sure).

Don’t lament over the lack of info. Remember any reputable speed shop can examine at least the bolt ons as well as the tune. Most of us modify with bolt on parts. Cam, heads etc. can be a bit tricky to determine. Call it the cost of doing business & go get the tune checked. At the end of the day … no matter what mods you have, it all comes down to the tune. I would want to know just how dependent I am on meth. While these kits are reliable, if it is crucial to the life of the motor that meth sprays you need to know it. I would be sure that the tune includes some sort of ( or multiple) Fail Safe built in to save the motor should the meth NOT spray for some reason.

Get the tune checked !

 

Do you still have this car?
have a similar situation and would love to ask some questions
if you’re able to message me.

thanks!
