Advise on Water Methanol setup

Recommended Posts

Hi

 

Car: 2JZGTE JDM PT 6466 Gen2

ECU: Motec M1 ECU with provisions for Water methanol

 

**In Ireland , its near impossible to get E85 , Flexi fuel sensor is not a viable option

 

John Reed firmware is based upon MoTeC GPR package which includes the following features:

Water injection control - with failsafe for boost/timing/fuel based on pressure sensor feedback

 

Water injection: John said he usually grabs pump and nozzle. Reservoir depends application. Then I just use a relay to let the M1 trigger the pump, and a 150psi pressure sensor in the meth line between pump and nozzle for the failsafe.PT

 

Any recommendations on , pump , nozzle , relay and pressure sensor ?

 

I was talking to Dave Rowe but he never got back yet with recommendations

We've just integrated a Snow Performance kit into a 996T with MaxxECU. The kit is however only used for spraying water on the intercoolers (which works like a charm). The kit was pre-installed when we installed the MaxxECU and connected to the OEM MAF sensor IIRC. The controller expects a 0-5V signal you can configure the voltage levels where it starts spraying and where it is running the pmp at full power. We set the starting level to slightly above 0V and full power level to slightly below 5V. In the MaxxECU we can now control the kit with a map based on IAT, boost, or whatever we like. The basic principle would be the same for water-meth injection. We only need to add a pressure sensor to the water lines, that's missing in the kit.

Why is a flexfuel not viable.

 

If you can get methanol for WI kit you could mix in the tank with flexfuel and not have all the extra WI kit to go wrong, I am guessing your ECU can support flexfuel, if not then obviously this is not an option :D

methanol is too expensive, was just going to use water

 

Priced it here, its 65 euro for 19 litres

 

I am installing a flexifuel sensor too
