Injectors on the GoEFi4 model guide.

Thanks to Roque Partida and Brian A Goad for helping me with figuring this out.

Hey guys wanted to post this for everyone like myself that was looking for better injectors for their fitech.

Here's what you'll need:

1. Injectors, comes with 8. (You'll have extra) https://precisionautoinjectors.com/products/80lb-bosch-4rd-generation-pico-short-height-ev14k-fuel-injectors
2. Foam Tape. (Any will work)

I recommend that before you replace them, you replace you fuel filter with something like this:
1. Better Inline fuel filter (buy the better 10 micron insert)

Steps:

1. Remove the old injectors and install new injectors.

2. You will need to slightly bend the pins down, if not they can cause an error in fitech. I belt mine a little using my finger, nothing crazy.

3. Apply the foam tape to prevent connectors from getting loose. (Image attached)

4. Check how many bars your regulator is, will say it on the side of regulator. (Image attached). Take note of it. If it's 3bar, it's 43psi. If it's 4bar it's 57psi.

 5. Put everything back together in the fitech.

6. Go into settings and go to Pro Tuning, then to Injectors. The first listing should be flow.

7. Take a note of what the number is at right now. It should be 75ish or 37ish. The part that got going crazy was this here. I'm not going to entertain you how it happened but shit happens.

8. Change the setting. You should have one of the bottom 4 choices. Only one will apply to you.

If you had it at 75ish psi and you have a 3bar regulator, you need to change it to 70psi.

If you had it at 75ish psi and you have a 4bar regulator, you need to change it to 80psi.

If you had it at 37ish psi and you have a 3bar regulator, you need to change it to 35psi.

If you had it at 37ish psi and you have a 4bar regulator, you need to change it to 40psi.

9. Make sure you send the change to ECU.

10. Double check the connectors are tight.

11. Get her started!
