do you have an m156? Cause sounds like you have a supercharged Motor?

sorry, my bad...yes, i have m156.

mods: ecu, first cats removed and agency pulley, better? :)

yes better. The answer is yes you can. You only need 550 injectors when you install headers.

great, thanks.

and why need 550 inj. with headers?

because due to the nature of e85 it requires approximately 30 percent or so more fueling. The stock 450 cc injectors cannot keep up with those demands when you add power adders like headers you will run lean.

Any power gain on NA engine? To be specific M273. Thanks!

Ok my bad I figured it is actually for NA m156. Would this kit be applicable for m273? I guess stock injectors may be an issue

someone tested E100 with stock injectors?

I bought 30l 100% Ethanol and want try, should work, or?



i hope for better performance compared with the e85.

this kit is a MUST have for n/a M156

Honestly i dont see you gaining much if any more performance over e85. E85 is already 105 octane. You gain only so much with n/a. Now boosted well little different. You can try it watch your injector duty cycle. Personally I’d stick with e85.

Ye maybe, will see.

I know from wiki, E85 have mind. 104octan - 107.
Pure ethanol is around 130. so should be better :)
Our E85 is mixed with little water and 95octan petrol :/

Unless you have insane tuning for it you won’t see much of anything.

3–5 gear.

Is the duty cycle ok for E85? Btw. can i test e100 with this duty cycle?

Your almost 95 percent so no I would not do e100

No. drop the ethanol content down to e60. You’re stressing out your fuel system.

Just installed the AFD/EC kit, took about 30 min.

Pretty good set up a few points to note - mine came with no instructions, there is a video on youtube but it doesnt tell you a few things

1. How to place the wires, need to be on the intake side as I cant secure airbox after thinking i could tuck around fuel rail, foam insulator doesnt fit them there.

2. The main unit placement on RHD cars- you cant use the LHD placement ive yet to decide where to put it permanently, it is secured by zipties currently

3. Your existing injector wiring may be brittle - i heard the wire insulation crack on a few of mine, try not to bend them too much.

4. If you dont change injectors you dont need to touch fuel rail, you can remove existing injector plugs with needlenose pliers then new ones push fit just fine.

5. Ethanol sensor plug takes quite a bit of force to click it in.

I do have one question though - how do i remove the new injector plugs from the injector? Im terrible for breaking plastic clips and now all are on I cant see how to remove so i can re route cabling.

Sounds like a very comprehensive kit - well done!

Have you utilized this with any boosted cars yet?

Found the answer in the very very long 18 pages of thread. Lots of good questions and dialogue - Thanks guys!

literally all you should need is a flat head screwdriver to move the locking clip and jiggle the connector loose.

the video should start at 4:51, if not skip to that time and you'll see kind of how its done from far away from an ex mercedes mechanic.

I'm still on the fence about doing this. I'm ready but it seems like the drawbacks can get you. I looked through all the pages and it seems it's best to do this with new injectors. I have not seen a kit that includes everything in one including injectors. At least I have not found one yet. On average are you guys happy with the install and performance upgrade of the E85 setup?

If you call Eurocharged in texas they can sell you the whole package with injectors. Comes out to around 2kish

Yes extremely. Cheap to fill up. Noticeably more power. Car runs great. I just don’t run e in the winter but now that my car sits In The garage in the winter it doesn’t matter. 100 percent e85 all the time 2 years plus strong

Did you get a custom dyno tune? Have you ever tracked the car with e85?

tracking with e85 shouldn't be an issue. you'll find lost power because alcohol when converting to a gas will lower combustion temperatures. when its hot outside with gasoline i feel a power loss. with ethanol i feel almost no loss, or very little.

I'm very happy as well. Some folks are really dialed in, some folks may be overthinking it. For me, I'm mostly stock. So my approach was simply to install new stock injectors on my 70k motor, and install the rest. No custom tune or E85 map yet. Works great! On the wish list sure, an E85 map, but that's just icing. And yeah I track my car with E85.
