Water / Meth injection details

[Nik0las]

On this topic. I have read that usually with mater/methanol mix they add a bit of transmission(like 50-100ml) oil to prevent eventual corrosion. Is this correct?

I just order AEM 30-3000 kit and I will run 50/50 mix with map so I'm wondering would be ok to add a bit oil....

Uhm... no?
I don't think adding oil is a good idea at all.

Not only will it lower the octane rating of the fuel, it will also cause buildups in your combustion chamber.

Oil and water don't mix so it will be droplets which will also block your water jets and slow down / jam your pump...

@Greg & Djones

You guys run a progressive system or just an on/off system?

@prj

do you know if a6 2.7t ecu can be made to control a valve like the rs4 flap valve?

Sure, the hardware is the same.
But the flap valve is not meant for PWM, it's an on-off signal.

[Jonas_R]

I know, was considering just running it as a on/off system.

Does the map that contains the control of the RS4 flap valve exist in the A6 software or do one need to use RS4 software as a base?

You either need RS4 software or you need to write some code that will control the flap.
That said - I don't think "on/off" is a very good idea... but I guess you could trigger it based on load.

Main problem is that if you do it this way it will flood the engine down low and go lean up top.
Plus, it's a good idea to have a meth kit that has a failsafe and switch maps in the ECU based on that - I do this on my RS4.

Yeah ok I think I will just stick with the AEM unit for know then

How are you going to tune a boost referenced W/M injection on a mass-flow ECU?
You will never get your AFR right.

You need Aquamist...

[Jonas_R]

The map is not made for W/M injection, simply just adding it to get some extra cooling.

Boring...
If you are going to go through all the trouble, do it properly

My AFR went from 12 to 10.5. I leaned it back out to about 12 and I can now run 7-8 degrees more timing with 0.1 bar more boost than on pump fuel.

Car should be about 500hp now.

[Jonas_R]

Your properly right, but at the moment I will settle with boring

That was way I wanted to use the RS4 flap control, because since it is just for extra cooling then I believe on/off would be more then enough.

Would also have been easier and cleaner install with the RS4 flap control.

Your AFR will still go too rich.
How many cc are you planning to run?

[Rocco]

With what %?

[Jonas_R]

260cc with 25-30% denatured alcohol
