Default My E46 M3 with 69mm Borg Warner Turbo - AEM Infinity // HFS3

Hey guys,

I work at a shop in Calgary, Alberta Canada called VEX Performance as a Tuner and Performance Specialist. We have been working with Aquamist systems for quite a long time and have always had great results and 0 failures on these systems. A big part of doing water/meth injection correctly is setting up proper redundancies. I do most of the standalone tuning here so setting up the custom strategies required is a bit easier than using a stock ECU.

I thought I would share this one out of many projects I've done because the results are almost unbelievable. The S54 engine is 11.5:1 Compression and I'm pushing 16psi through it at 3500ft. elevation to make this power on a Dyno Dynamics.

This is my personal car, 2003 BMW M3 with the following engine modifications:

-Completely Factory S54 Engine (unopened)
-Custom Built Turbo Setup
-Borg Warner S300SXE 69mm turbo
-TiAL MVR Wastegate
-Adel Wiggins Clamshell Couplings on cold side IC piping
-Custom built intercooler by Bell (my spec)
-Dixis Spirit Exhaust System
-Radium Engineering Fuel Pressure Regulator
-Radium Engineering Fuel Pump Kit w/450LPH Pump
-Radium Engineering Catch Can Kit
-Radium Engineering Fuel Rail w/ Center Damper
-Radium Engineering FPD-R Damper
-Injector Dynamics ID1000 injectors
-Aquamist HFS3 Water Methanol Injection System
-CSF Aluminum Race Radiator
-AEM Infinity 10 ECU, tuned in house
-AEM Fuel Pressure and Temp Sensors
-VEX Performance 4-Port BCS
-Innovate LC2 Wideband w/ DB Gauge
-STACK Pro Control Boost Gauge




Blue Lines: 6psi (spring pressure) on local pump gasoline (94 octane - E10) **452WHP**

Red Lines: 16psi on local pump gasoline (94 octane - E10) and 51:49 water methanol **630WHP**


I'll show you guys my control strategy.


I am just using the map switch function on the HFS3 board without a map input or boost dropout. That is being done through the ECU. I've set up the map switch 5V trigger into an analogue input which I've setup as a "nitrous trigger" in the ECU. When this trigger is active (5V / turn on meth system) it will overlay on the nitrous maps. After tuning the VE table correctly on gasoline it should still be correct under more boost, but regardless you are using it as a trim for all boost levels.


The input as you can see here is Analogue 14 (voltage input). I have latched this input to 2 separate functions.
-N20 trigger
-Mode Switch




The purpose of Mode switch is to change boost levels. With the controller off it runs on mode 1 (wastegate boost). On mode 2, it runs to 16psi. Mode 1 is anything under 1V (0V when aquamist is off) and Mode 2 for anything above 2V (5V when aquamist is on). When this goes into failsafe, the AEM will instantly jump back to mode 1.






Here are the nitrous / N20 comp tables that overlays the main VE and main IG





And last but not least....a video!

Thanks for reading / watching, and keep spraying the meth!

I'll get some better pics of the jet placement in the next few days.
