In today's video, we'll install bigger fuel injectors on the Evo 8. I'll cover the physical installation as well as the process of scaling and adjusting the latencies with the stock ECU.

The metal clips are such a hassle. I gave up for the night. I never got any of them back yet. I think I’ll put them on before I put the injectors in place.

I know, those things are such a pain!

Hey there. I'm new to tuning. There's no dyno in my country so I have someone helping me etune. I recently put in a bigger turbo and I had new stock oem injectors that I was running. I decided to use FIC 950cc injectors with the new turbo. When I installed it, I'm running lean and cutting off. I got it to idle but it wasn't idling rich. My tuner scaled the injectors and now it's not starting and when it does its super lean. I changed all the fuel components to new parts. New pump, braided lines, rail and fpr. I'm not sure why the injectors aren't scaling. I get 5v at the injector clips. When I put back the oem. It runs fine but I'm getting a knock at WOT. If you could provide any input I would appreciate it

Hello! Sorry to hear you are running into issues. Some questions: What kind of scaling numbers/latencies are you running? What is the state of your battery/charging system? What is the voltage coming into the injector resistor pack? For knock, what kind of counts are you getting? Is it repeatable at a given load/rpm? In my experience these cars are super sensitive to timing at peak tq. What kind of timing are you running there?

@@supercarmio Hello, appreciate the response. Forgive me if I say the wrong things, I am new to tuning. The injectors are scaled to 835cc and it's not running at all now. When I first installed and it was scaled for stock, they ran but the afr was 14.7 to 15.1 at idle, I thought it would be super rich. I only get knock during WOT, I get about 6 counts, this was with the OEM injectors. It happens consistently and only during WOT. I wish I could give you the rest of information but I am pretty new to tuning. I have the rom file that my tuner sent me. I log using Evoscan, I have a ZT2 logger installed. This is all new to me and I hit a wall. I can put back the OEM injectors and they run well but then I started getting knock. I have to check voltage at the resistor pack.

@@supercarmio so I got access to the Merlins how to tune guide and saw that the tuner did not adjust the latency values to match the FIC 950cc injectors. So I adjusted the values and will try that ROM when I am home. If that works I'll let you know.

@@sayyidferouz3880 Cool yeah sounds good! I would hold off on WOT runs until you get the injectors sorted. Also double check the voltages at the resistor box.

Great video man, you make a lot of things look easy, been waiting for this vid for awhile, thanks for the update, can't wait to see how much power it's going to put down..👍

@supercarmio 5 лет назад

Appreciate it man! Glad it was helpful. Excited to see the #s as well! 🙌

@87sprintqf 5 лет назад

Well explained! Thanks for the video

@supercarmio 5 лет назад

Thanks man! anytime ;)

@Thr33.Sid3z 4 года назад

I was excited for this video, but I gotta say, I was a little disappointed bcuz you didn't really show us any of the adjustments you made on the tables. It's always easier to understand when you have visuals along with the explanations. Just a little positive criticism... Thanx for the vids tho broham! 👌🏽

@supercarmio 4 года назад

That's fair! I always try to strike a balance between doing stuff that might lose the viewer's interest but is helpful vs not including it. Sorry this one missed the mark for you. Thanks for watching though man.

@doctorlobsteroctopus 5 лет назад

Glad to see the Evo back in the video rotation, love this car.

@supercarmio 5 лет назад

Thanks man!! Me too, it's really a blast. Will be posting an update shortly 💪

@HemiLyfestyle 5 лет назад

I don't even own a evo but I think its something I would love to own, Probably sell my Modded Chrysler 300c 5.7 for a Evo, your year model. I love the evo 9's. The 10's look eh lol

@supercarmio 5 лет назад

They are super fun! You should totally grab one if you get the chance. hahah totally agree, the Xs are super meh to me as well.
