Have you got any graphs with and without watermeth?

send me a pm
and i will explain
there are lots to do
your setup is basic compared to myn :)
oh and that power on myn is from a b16 bad tune 151KW
Im not sure how you have gone about it - but you cannot simply inject water meth and expect your car to make more power. Contrary if you inject water-meth ontop of your normal fuel mapping, you will over richen you fuel mixture. This will cause the combustion process to drown (yes you will loose power ) and even possibly cause misfiring (depending on how much your injecting).
The whole purpose to water meth is to have you car tuned with this equasion involved in the fuel mixture - This means your fuel mapped units will be lower as the water meth is actually a source of fuel. The benefits of water-meth injection are A - cools your intake and combustion charge, B - Reduces the tendency of your fuel to detonate (this is like running a high octane fuel) - It is because of this you are able to run more ignition timing in your tune and hence make more power.
There are some risks to this depending on your setup. Firstly if you are only running a single injector before your throttle body (i assume you are) - you do not have a controlled amount going into each cylinder. Some cylinders could be richer or leaner and the tuner really would have no way in knowing as they only use a single o2 sensor at the back of your exhaust (averaged out o2 reading of all 4 cylinders).
If you are using water meth to extra more power i would strongly recommend useing a low level switch in your water/meth tank, and using that to trigger a input on your ecu to bring on a different table or even a generic output to add fuel, reduce timing etc.
AND - buy a wide band and have the 0-5v signal datalogging into your ecu and setup lean-out protection with a conservative value. e.g. Over 10psi, a/f under 12.5 etc
If you are running injection and you dont want to play around with the fuel mapping all that much, ditch the methanol and just run Demin water. The methanol will do you more harm then good if you dont use it properly..
hope this helps
any updates on yours yet
Ive had myn retuned and now have lots more KW's :P
Good thread but would like to see MOAR PWR?!
This is too true. Just run water if you are just looking for cooler intake temps.Quote:

Goodluck finding out the issue.. keep us updated :)
Or run a LHT manifold if you want cooler intake temps
Exactly right Grifty. I started to think about intercooled supercharger setups for this fine gentleman but realised noone else put that idea up there so I thought maybe it may be too much money / work for him to incorporate that one in now.
(Y) Love your work.
LHT is expensive, and might not be worth it for everyone
$845 for the modification + postage $$?
$200 heat exchanger
$20 lines
$50 fittings
$50 reservoir
$200 water pump + coolant $$?
vs
$400 AEM water/meth kit + methanol $$?
