After I get mine fixed this week I am going to order another nozzle to run pre turbo. It still has a ton of timing overhead but I want to get the dual nozzle in place before I start ramping it up.

i dont think he means pro-tuner as in the system, but a professional tune from a person who knows what there doing.

I may have missed it but what kind of fail safe will you be using? Does link allow and input for low fluid level/no flow/low pressure to trigger your maps to pull timing and add fuel for the lack of meth, or vice versa?

I've got a water meth setup from my last car I will be installing soon. I will be using the nitrous map on my aem to pull fuel and add timing when it sees a signal from a flow sensor in my meth line, I'll also be wiring in a low level sensor that won't let the pump run if level gets too low.

Link does not support additional sensor input for low meth level or line pressure. It merely activates the solenoids, your better off using a external controller with link providing the signal to the controller to inject the meth.

I have never bothered with controllers, I just use a boost activated switch to turn the pump on or open a solenoid, then it just sprays at 100% duty.

Does link not allow secondary map tuning for meth injection? Or even nitrous?

If not I hope you have a clear warning light to tell you when the system has stopped injecting. Unless of course you don't plan on tuning for the water/meth and are just using it for the increase in detonation ceiling and lowered iats. I prefer to get the most out of it and tune in the additional timing and lean out the rich mixture while spraying.

You could always setup a two stage boost controller, and retune your timing and fuel on the high boost portion of the map and leave the low boost portion safe for no water/meth and use a warning light for low pressure/low flow and when you see that light come on just make sure you have your boost controller set to low

Link does allow for a second set of timing/fuel maps for use during meth or nitrous.

This is basically how mine is setup. No controllers. Just a Hobbs switch telling 'link when to switch maps and when to start spraying meth. There are failsafes built into my setup as well. A second Hobbs switch is mounted at the nozzle. If it doesn't see meth pressure, the whole system shuts down, 'link reverts to the pump gas map and the boost controller goes to low boost. Been working great since '06ish.

Lol.

No fail safe, just a upgraded solenoid controlled under boost.

I don't daily my car and I plan to have the meth turn on at 10psi.

Just got done installing the lines

When was the last time you did a BLT?
