For anybody wondering, I ran the flex fuel kit on stock injectors for almost a year no issues. This was on stock headers but tuned (row, 2nd cat delete)
I recently got my long tubes and retune done and ran a mix of e40-e50 no issues. Will try adding more Ethanol and monitoring my injector duty cycle
I have been running the eurocharged/AFD e85 kit with upgraded bosch injectors for over 30,000 miles during the past 18 or so months with oil analysis from blackstone since the start. Car was dyno tuned for e85/catless headers by Jerry from eurocharged. e85 is the primary fuel and I run a tank of 93 through her every 3000ish miles with a bottle of redline fuel injector cleaner just for good measure. Car runs great
once I ran through my first tank and all was well I filled up then confirmed ethanol reading. once I saw 75% I went and flashed OE's 100 octane map... will give it some time before I lay on it as to allow the computer to adapt.
flex fuel so far is addicting. the added power and smoothness of engine is addicting. I guess that's why they say no amount of power is enough... you always want more.
Thank you! I looked for those everywhere to make my own kit instead of paying 200 bucks to a tuner.
Where did you put the temp sensor for the kit? I left mine near the fuel rail but was getting insane temps on the app and I think it was dumping to much fuel because of it.
first place I mounted was next to the fuel hard line on my W211. after installing my airboxes saw that it was coming in contact. now it's temporarily ziptied to the plastic brake booster line. I will need to figure out a better mounting location at some point. temps seem fine. will need to monitor more as it gets hotter out.
one question, are you guys running those foam things under your airboxes? they're a little too thick to fit with the added wiring harness on my car. thinking of removing them entirely.
btw...OE's 100 Octane map in daily driving so far for my morning commute feels pretty awesome with the reading of E75 on the sensor. feels like from the 15-20hp i gained prior that i gained another 15hp in the low/midrange in short acceleration bursts.
feels great...haven't given it all yet...so far so good.
lost 3 more mpg though in comparison of E60 to E75 on my morning commute....MPG is pretty horrid.
for those who have asked what other injectors will work...from what I recall at times there is an aluminum spacer at the feed end is placed onto the injector for correct spacing. you don't need to remove the spacer if it does not come with one. proceed at your own risk, as I do not know if these are glued on or not. but we are looking at Bosch/Bosch Motorsport EV14 injectors which would come with a EV6/USCAR injector clip. you will need to confirm dimensions of the actual injector end to end as I do not have these. many of the retailers here can supply these injectors as well.
I purchased the RM oem injectors deal, as well as the injectors mentioned by ECE above (ebay deal, amg55 designation, and off to my nephews E55 build if they don't/can't work).Injector on right is oem (#1560780023-MFG14 - individually boxed) and on left is amg55 w/adapter (#0280158117 loosely bagged w/adapters). Simple caliper measurement put mounting length/width nearly identical(didn't want to pull from the sealed package yet) but there's the obvious nozzle length difference?
Most recent info I can find: *EC has mentioned large increase in injector prices and according to a recent post by an MBW member, is recommending 5-0 Motorsports which I assume can make(have not contacted yet), but no MB injectors online and no part #s *VRP Speed stopped offering a 550cc option a while back with smallest current offering being a 630cc - no part# *Been a while since I've checked, but various SC mfgs mention a 550cc injector in their package - no part #
My plan is E85 with both cat deletes(no headers) and would pay up a bit for the HP/HR but can't see the extra $400+ over the RM oem deal on the current 'verified' options being worth it to me - that could obviously change when I get there Unfortunately, it'll be a while before I do - too many projects and this is all I can bring to the table for now.
does applying gold tape to all intake ducting within the engine bay help with temps?
Marginally....it’s like adding hi flow air filters. Really hard to notice. Especially with a hood shut on big ol lump v8. Wrapping headers helped me tremendously
To report...using the OE Tuning 100 Octane Map, E75 mixture felt great...E78 is slower and a little sluggish. The tune does not seem to utilize the additional octane efficiently which is expected and no fault of the tune. With anything, you must run the appropriate octane for of which your ECU was optimized for. Any more or less will greatly affect power, performance, and MPG. Will possibly mix in 91 octane to bring the mixture down closer to 100 octane to regain MPG and power. An effective mixture of E50 should put me at 100 octane. E60 to be safer.
Does anybody else have similar feedback with their tuners 100 octane map? What about gallons in tank and how it equates to markings on the fuel gauge.

Has nothing to do with the tune. You are experiencing diminishing returns. Same effect when people over octane with race fuel. Leave car at e60 max.
I would assume 87 octane mixed with E85 would be the same as mixing 91 octane with E85 if the effective octane target is 100? probably going to start mixing 87 octane and E85 to hit targets.
E100 (100% ethanol) has a yield of 34% less gas mileage than gasoline (10% ethanol/90% gas). Which means running 100% E85 (85% ethanol/15% gas) should yield 28.9% less gas mileage. When running E30 (30% E85/70% Gas), it should yield 8.7% less gas mileage.
When running E40 (40% E85/60% Gas), it should yield 11.5% less gas mileage.
When running E50 (50% E85/50% Gas), it should yield 14.5% less gas mileage.
When running E85 (100% E85/0% Gas), it should yield 28.9% less gas mileage.
My local Shell gas station carries E85 for $3.79 and 93 for $4.39. That's a $0.60 difference or 14% savings a gallon over 93 octane. This means that when our cars tank E90 (16.6 gal with reserve) is full with E30 (5 gal of E85 + 11.6 gal of gas) we save an additional $3.00 at the pump. This also means that we lose mpg. E30 = If you average 22mpg then you’ll average 20.1mpg. (Drops from 365miles to 333 miles per tank) {Savings of $3.00 at the pump}
E40 = If you average 22mpg then you’ll average 19.5mpg. (Drops from 365miles to 323 miles per tank) {Savings of $3.99 at the pump}
E50 = If you average 22mpg then you’ll average 18.8mpg. (Drops from 365miles to 312 miles per tank) {Savings of $4.98 at the pump}
E85 = If you average 22mpg then you’ll average 15.6mpg. (Drops from 365miles to 259 miles per tank) {Savings of $9.96 at the pump}
-So paying $3.79 for E85 and $4.39 for gas 93 at the pump nets to this. E30 = You’ll be paying an average of $4.21 a gal - [$0.21 per mile]
E40 = You’ll be paying an average of $4.15 a gal - [$0.21 per mile]
E50 = You’ll be paying an average of $4.09 a gal - [$0.22 per mile]
E85 = You’ll be paying an average of $3.79 a gal - [$0.24 per mile]
Now I’m trying to figure the delta on how much power is introduced when 10% increase of ethanol is introduced (E30, E40, E50)... Maybe someone can give us some logs on their testing.
I would assume 87 octane mixed with E85 would be the same as mixing 91 octane with E85 if the effective octane target is 100? probably going to start mixing 87 octane and E85 to hit targets.
I filled up about 3/4 tank of E85 (measured 80% content) and topped off the 1/4 remaining (5.15 gallons of 91 octane).
Drove about 3 miles to mix the fuel and ethanol content measured 60%
Im going to try 87 octane and E85 mix next tank and measure what percentage comes up.
Cold start on E60 is a lot better than on full E85.
I don’t get these issues and overthinking the mixes etc. I’ve just got the EC kit, no special tuning as of yet, and just run full E85 which out here is measuring about 75%. No issues. Fill and go.
