You're friend has water/meth injection, what J is referring to is adding meth to your fuel as a percentage (common is a 10% or 20% mix) and having a map to suit this mix. You would need an ecu like an alcatek to have one map just for v power and separate one for v power + meth

 

This ☺

I would avoid water meth injection, there are too many variables. I would also point out that it is not technically road legal so running it all the time is not a good idea. Also your fuel lines won't like it....

 

Fuel lines is a bone of contention imo.

I ran it solidly for over 2yrs...... not one issue with OEM lines or injector seals etc.

 

Yeah.... Dazdavies told you!

I ran 20% methanol on the LM450 Billet and achieved just over 490bhp.

 

BTW.... if you're on the OEM JDM ECU for your car, you can use EcuTEK's "RACE ROM" functions. You don't "need" a new ECU to switch between a Meth and VPower only map.

 

490 with mine lm450 20% meth and syvecs goes well

 

Them results are really good! Looking into it a lot more now, I want to run it with alcatek ecu in my classic with a new age enginw conversion
