This install is on a 2009 135i, but I don't see it being much different for a 335i.

I've had my ethanol analyzer and fuel line kit sitting around for a few months and finally decided to do the install. I was sort of dreading it because I thought id have to pull the intake manifold to change the HPFP line, but managed to do without removal. I followed Steve's videos and the install was a breeze, but there are a few steps which could hang people up.

The kit was nicely packaged and everything labeled:



High quality stuff, I was definitely impressed. Unfortunately, I was missing two clips for the sensor. I called Steve and he was super professional and apologetic and advised me which clips were needed. I found them at my local auto zone so it wasn't much of an inconvenience, as I had to go there for some supplies anyways. These are the clips:



I pulled the engine cover as I thought I would need to remove the intake manifold, but it was not necessary. I removed the air intake assembly, the throttle body, and used a bungee cord to pull all the wiring out of the way.



Plenty of room:



I was left with enough room to remove the old fuel line and reattach the new one. Tip: Put the clip on the metal line FIRST and grease the fitting, then attach the new line.



I wired the sensor to the passenger side DME box and tapped the Red wire with a white stripe, as this is only powered with the key on. I tested it with a multimeter and it shows +-12-14V with the ignition on and +-.01 with the car off.



After everything was back together, I filled up at my local station and the result was this:



Just to be sure I double checked the ethanol content with my manual kit and its right on. Perfect.

I flashed the car to MHD E60 and it runs great, no leaks, no issues. Ready to hit the dyno now so I should have those results posted soon. I couldn't be happier with the kit, the install was easier than anticipated and as usual Steve puts out a quality product. Let me know if you guys have any questions on the install.

Nice. How long did it take and is that Fuel-it's recommended power source?

Fuel-it's directions advise you to tap into the JB4 power wire (I think), but I'm not running a JB4 so went this route instead. Total install was about 4 hours.

Thanks. I don't run a JB4 either so I wondered if they gave you a alternative location for non JB4 users.

Let's see how long these stock turbos last at 20psi. As soon as they blow I'll be in the market for some GC's

20 psi on stock ? You really do want replacements.

Although my poor stockers ran 22.5 psi midrange tapered to whatever miserable boost my destroyed wastegates would allow up top for a ton of miles; I think it was something like 11.5 psi at 7200 rpm was all they'd do. lol.
