I got some Flow Force 640 cc injectors and got them installed this weekend. And as usual I did a video of the process. While the injector install is probably old hat for most of you here, I also replaced the engine bay hoses with e85 compatible ones and plumbed in a GM flex fuel sensor (the small version). So if you want to see how I "mounted" it, click below.

Also included is a plug for mkturbo because Lars helped me out on the injectors. Thanks man!

Part 2 - This is the wiring for the e85 sensor plus the setup in TunerStudio. I also did a street tune on the new injectors and hardly anything had to change on the fuel VE table. Yay Required Fuel calculation!

Does anyone have a good place/bracket to mount the FF sensor on? Mine is just hanging in space and I'd be happy to redo my lines just to get it in a nice place.

Pedxing

Nope, mine's in space also, lol. However it would be not to hard to use either the bracket for the charcoal canister or the bracket for the EGR solenoid or the evap solenoid. Or bolt some flat stock to one of those and it would extend out a bit and then bolt or tie down the sensor to it. My sensor is the small one with no bolt holes so I would need to strap it to something regardless.

I saw a 3d printed one online recently.

Nice video! Do you mind if I embed it on the instructions page at goflowforce.com? I'm sure it will help some folks with their injector installs.

Here's how I mounted mine

This is the old location. It has since been moved to the middle bolt on the fuel rail.

It's installed on the return side instead of the pressure side. This allows us to run the engine with the "out" hose of the sensor dumping into a fuel jug for emptying out the tank and trying to raise E content as high as possible. The car is driven to events so this is very useful.

Will try to get pic of new location but uses same "bracket" which is just a piece of bent up metal, in this case stainless.

Pedxing

Sure, go for it! Glad to help.

That's nice and clean, thanks for the pic.

Just caught up here -- thanks for the suggestions!

Since you brought this up again, here is a shot of the new location of the flex sensor. Obviously ITB's so can't say for sure it'll work with a standard plenum manifold.
