Water Injection map, 45psi boost gauge install, trivia, and 1/4 mile fun

Oct 18, 2026

This video shows you how I connected my 45psi boost gauge, and exactly how my water injection map is set up. No secrets here!

The gauge itself has three wires, power, ignition power, and ground. I connected them exactly as seen in my video on installing a plug and play gauge.

I should rephrase what I said about adding boost to an ECU tune. I have done it, and it works. However, that's a long way from having a driveable reliable tune. I haven't done that. Which is why I ran the car at the track with only the standard Phase 2 flash tune and water injection. At this moment I consider the Vaitrix box usable as a stand alone tuning box, or to run water or water:methanol injection. I'll keep you updated when I have done more.

This car is currently the fastest 124 in the world that I know of with its [email protected] run, and the fastest ever on gasoline. Mods are EC Phase 2+ tune, EC V4 intake, EC big intercooler, Vaitrix water injection.

Note: I misspoke regarding the boost gauge connection. That's not an evap line I taped into, it's a CCV line.
