For you big runners out there with the Methanol and Water injection....why did you pick the one you have ? I mean Methanol is gas , and gas = $$$$, when Water = cheaper than gas. Why would you pick Meth over water?

 

People run Meth because it increases the overall mixture of the fuel. Water cools more efficiently though. My preference is straight alcohol as it offers the same benefits as methanol while requiring less volume than methanol to be effective which allows you to be less dependent on it should the system fail.

 

So still to be said why would you wnt to spend so much money on something like alcohol or Meth when water is comparitivly free. I mean it cools the intake charge really well and the last time i checked for people in remote areas it is hard to find Meth compared to water. So the benefits of meth just isn't over powering the easy accessability of water.

 

ok heres a quick stab - meth/alky increases the effective octane as well as cools the intake temperatures. I am assuming here you get much more power from being able to up the boost, and use more aggressive timing than from just using water injection. - no one cares that water is cheap - most people can get alky/and meth cheap enough in bulk that the added power is more than worth it.

So do tell what are we talking about as far as affordable bulk pricing on Meth ?? I understand the difference now (unless anyone has something to add) about the attributes of Meth but i thought that one of the big perks to water is that it cancontrol detonation to the point where it could be tuned out to higher fuel standards such as Alky....wrong??

 

meth cost are 4.5 a gal that lasts a full gas tank typically or even more. Unless you are in boost all the time.

 

Aux, water can only cool the intake charge - that's it. Meth and alky burn as fuels, thus raising the effective octane so that you can run a ton more boost with a ton more timing. YOu can make a lot more power with meth/alky than you can with water. Who cares that alky or meth costs more than water? You don't buy an alky kit to worry about the cost of alky. For me, I use 100% denatured alky, which is the most expensive of the 3 choices here, but I couldn't care less. I spent $12.77 every 2-3 weeks to put in 1 gallon of alky in my daily driven Evo. I barely notice.

 

I have a question,

Is there a solution for two maps running off the ECU, one with alcohol injection, another water alcohol injection (or preferably a third in case I want to remove the injection system for warranty work)?

 

It all depends on what the tuner is comfortable tuning. For water, you need to have the AFRs in the 12s for it to work.

Also, for water injection, you need to have a more sophisticated injection system to "dose" the proper amount of water to fuel, too much water and you will quench your combustion, leading to a loss of power.

Water is a great steam cleaner too:

The top of my pistons were shiny, unfortunately it was too far down, could not get a good pic of it.

 

hmm....how about have 2 extra ECUs tuned for waterhol - alcohol
1-stock
2-waterhol
3-alcohol
so just plug in what ever you feel like running

 

Is there a company providing ECUs mapped?...I understand they exist for flashing your existing ECU, but the only company I know selling mapped ECUs is RalliArt, and I do not think they do customized ECUs.

If this solution does not exist, there is a hole in the market. This whole "send your ECU" in and wait around thing needs a better solution....If I was a tuner, I would find a cheap way to provide pre-mapped and customized ECUs.

 

when you run water/alcohol, u need a custom tune, ON A DYNO! every car is different

 

Ideally you would dyno tune any setup (as every car is a bit different/altitude/etc), but that doesn't stop ECU flashes from selling and working well.

 

Warrtalon, is there a reason to run alky if you run a high octaine at the track. I understand why you use alky if your running 94 octaine as a daily driver...but what if you are at the track and running race gas? I am asking at what octaine level of gas is high enough where alky becomes obsolete. I am just wondering?

Thanks

 

you could do this with ECUflash...... store different maps on your computer and flash them on your ecu when you need them
