my checkvalve from devils own is fine... however the other day i think it decided not to spray...

 

what problems could arise if the unit doesnt spray or if you run out of meth? Like how do you know when its not working right? This may be a dumb question but I am clueless with the meth kits at this time but seriously considering going this route since I have the hahn stage v kit and we only have 91 octance fuel up here and they recommend 93 so I think this kit could help with that.

 

if you are tuned agressively for the meth, you could easily damage the engine if you run out of meth or it doesnt spray... too much timing plus a lean AFR = B00M

you will know cuz the car will fall on its face, your wideband will read leaner, and theres the good chance of detonation

 

I have the hptuners but as I said Im a rookie with that so right now I just have the tune on it that Aaron at Hahn gave me for the stage V turbo system. Anyone know who could help me out with tuning my car now for meth?

 

im pretty sure you just run it with the meth and see what youre afr is at WOT. then you cut the difference and command a leaner mix during these times so the sum of you meth + gas figured into the AFR is what youd like it to be.

say you want to run 11.5 at WOT and that is exactly what youre reading on your AFR gauge you then add meth with out a tune ad you are running 10.0 at WOT you would comand it to be 12 afr. then you should see your AFR gauge now read 11.5 while spraying meth. then you would finely tune your timing, and re adjust the afr if needed.

im no expert but that is my understanding.

 

I need to study this hptuners alot more because I dont even know how to do that.lol We will see how it goes.

Ask them anything, they are a huge help when learning hptuners

 

instead of making a new thread ill post this in here. i am having a similar problem. my meth pump kicks on as soon as the key is flicked to the on position. the car doesn't even have to be running. i cant figure out how to keep it from spraying all the time. any help would be appreciated thanks. and if it helps my power source is the sunroof and ground is under the trunk mat. thanks again.

 

bad switch, possible short at the switch
