Methanol Injection info

[dale_gribble]

What we need now is for someone that will design a failsafe with hooks into the car to automatically reduce boost/ignition in a meth flow cutout condition. I imagine it wouldn't be rocket science to create something that would measure meth flow and in the event of a failure, send something to the EBCS that could instantly and automatically force boost cut.

Since we don't have a standalone system, we really can't get a signal INTO the ECM to do anything so I think ignition is out (unless aftermarket ignition). I can't imagine it would be too crazy to intercept ECM _> EBCS signal and inject a different signal to EBCS to pull boost in meth flow cut conditions. Who wants to make some $$$?

The ignition advance can't be done right yet (or @ least with otc parts), but the aem failsafe will send a 12v signal to a relay which can operate a solenoid or bov and it will cut boost down to spring pressure.

Dano mentioned his was not particularly reliable, but maybe Faeker's idea would be a good substitute.

Thanks Faeker. btw.

And @dale_gribble; I hope that I didn't come off jerky in response to your post above. I'm just not a fan of water in the mix.

IMO, it may be worth experimentation for long, sustained periods of wot operation since it is said that h20 has a greater effect on cooling egt's vs. bat's, but for street use and an octane bump, 100% meth is best.

If h20 works for you, that is awesome too.

Water has an octane of infinity...........

That may be true, but it is not a fuel. In my experience, a high concentration of water eats up nozzle size, lessens the charge cooling effect of the methanol and only carries with it relative safety and cost savings vs. running 100% meth.

I have tried every variation of h20 to meth, creeped every forum imagineable in terms of meth injection results and 98% of the people running meth kits will tell you that 100% meth is the best performer when looking for the octane bump needed for running aggressive ignition advance.

The Aquamist actually does this. It has failsafes built-in for low and high flow conditions. You have to manually set the trigger points for those conditions, but that's fairly simple.

As seen in the wiring diagram, the meth controller taps into the EBCS signal.



If it detects a low or high flow condition, it opens the wastegate and dumps boost. I actually caught a log of a high flow condition. It was pretty smooth when it happened, too. It wasn't like running into a brick wall or anything.



It also has some added flexibility in that you can tie in other failsafes, as well. For instance, if the ECU has map switching capabilities, it can trigger that and change maps on the fly based on the condition.

@rfinkle2; My apologies if I'm cluttering things up. I can delete this if you find it irrelevant to the original purpose of your thread.

Nelson, anything you contribute is always welcome. Good to see you around.
