As you can see the only part you can see is the ethanol sensor. The box you can see in the one pic tucked down by the strut tower area. If you didn't know what to look for you would never know. Looks stock.

e85 is my next and last mod. I would like to run a e85 ONLY tune but if would have to be significant increase in hp/tq vs a flex tune

So Eurocharged, can you provide wheel hp and tq numbers that one would potentially see on your v7 header tune with a e85 tune vs a flex tune?

DavesMeanE's

You'r not gonna see a massive increase if you're on E85 and a flex tune, and go to the E85 tune. most of the power is in the fuel itself. While you can run extra timing safely on E, this isn't where the bulk of the power is made... you can expect about a 10whp bump with the E85 tune (over whatever you make on flex).

V7, LTH, ROW, Flex should put you at or above 500whp (obviously assuming your car is otherwise in perfect mechanical shape, which MANY are not)

Thanks!

What would be the mimimum amount of e85 you would need to be mixed with 93 pump in order to have your flex map performing to its maximum potential? Could you explain a little further on how the flex map operates in regards to having different percentages of e85 to pump?

AMGonFire

there are 12 pages that talk about this. Scroll up. The map is no different then anyone else v6, v7, v5 whatever version you have or get. There is no flex map. It's a normal tune. The flex part of it is the kit that has the box that adjust fueling. The amount of fuel mix is up to you. The flex fuel kit that is what senses the percentages of ethanol and adjusts fueling. Why would you want to mix just go full e85. But you can mix what ever suits your fancy.

Seriously this is all addressed in this thread. If your car is NA then it can probably only use 85% of a full tank of E85 effectively. Supercharged is about 100% but I haven't seen anyones results yet. I dyno'd 475whp on a V6 tune, row boxes, afe filters, and a secondary cat delete. Personally I like to have 1 gallon of 91 for every full tank of E85 just to make the car start easier. The kit takes only an hour to install, theres pictures and videos all in this thread of how to do that. E85 is significantly cheaper where I am at and available. If you read the whole thread and still have questions then just call Dave at EurochargedATX.

I suppose I could read through 12 pages instead of just asking the vendor who is selling the kit a question.

What failsafe is in place? Say this controller quits working, so it stops telling the injectors to bump up the flow. Does it go to stock flow or will it stop injectors all together to stop the motor? Is there a chance the controller 'breaks' and runs the motor too lean?

DavesMeanE's

That's a great question! I will start by saying that to date, hundreds of thousands of miles have been logged, without a single failure. Before going into it I want to first emphasize the quality of the electronics here, everything specified for use was intentionally selected and rated to AT LEAST **Hundreds** of percent over the requirements of the circuits. This Isn't some chinese crap box with the cheapest possible materials and assembly to get it out the door. Each unit is built in the USA, Tested in the USA, run on a real car in the USA before ever being shipped... SO now that we have that out of the way ... There are a couple possibilities... Ground fault - say the ground breaks for the controller - the car will simply shut off. Say the power is cut - Car will shut off. Internally, each injector has a dedicated circuit, and they are all run independently. It is designed this way to prevent a "global" failure. If one cylinder circuit fails - ECU will immediately detect misfire and shut down the injector for that cylinder completely. It has been designed in such a way that **IF** there ever is a failure - your engine is not at risk due to this system. Obviously there are plenty of other ways you can damage your engine, especially when you decide to modify it from stock.

Thanks for the question!

possible to get a group buy?

DavesMeanE's

That's up to y'all I'm happy to cut a deal for a group buy though

I'll call it the Halloween Group Buy!

bentz69 - I'm putting you in charge since you asked - Here's the deal:

You can make a new thread or whatever you want to get the word out and promote it so you can get that price

- 10 People sign up AND PAY by October 31st at Midnight (more are obviously always welcomed)
- Price will be $1,250 ($250 off!! ) shipped for a system (for cars with no headers) and +$400 ($80 off injectors!!!) for cars with headers ( I HIGHLY recommend you consider this anyhow, as we have had a lot of folks say that they wont get headers, but then end up doing it anyway... then they have to send the harness back to be modified and it ends up costing them more money...)
- They will ship the following week.
- Injectors are BRAND NEW **GENUINE** Bosch 550cc w/ serial #'s
- Easy as Pumpkin Pie!

Thanks

Dave

group buy started...

Very interested now that there is a group buy!
Quick question and i'm sorry if its been answered before but if i currently have a Eurocharged V5 tune. do i have to mess with the tune in anyway or just slap on this E85 kit and go?
Also does it come with proper instruction besides the youtube install videos i see floating around?

DavesMeanE's

Slap it on and go

Install is simple and tech support is always there when you need it

Thanks!

Has the problems with the car in southern california been solved involving this kit, i heard they were costly

thanks

What happened?

Huskymush

I would also like to know what happened 😀

CaptnCharisma

What happened was I had an injector get stuck wide open and that led to me bending a rod. Instead of replacing the engine I opted to rebuild it myself with a few upgrades. Just waiting on the main engine bolts then I can start putting it back together.

CaptnCharisma

skratch77

Was that with the injectors that came with the kit?

CaptnCharisma

Yes, one of the ported mercedes injectors. Pretty much the same as the ones I pulled out. Shortly after that I started seeing posts of people with that old style injector having misfires around the same mileage I had. I guess mercedes has gone through a few different versions of it. I don't really fault the kit. I could have kept my stock injectors and ran about the same risk. I have now swapped them all out with the Bosch injectors.

skratch77

I thought the kit gives you updated brand new injectors? I don't know I was going to pull the trigger but I'm staying away from e85 now.

Does there Warranty cover the cost to rebuild?

CaptnCharisma

The kit now does offer brand new injectors if you want them. In the beginning they would port used m156 injectors. Other than the size they were pretty much the same ones I had originally so I could of had no mods and still mess up the engine, saw enough threads of that happening to PFL cars. Honestly when I pulled them all out they were all spotless except for the one from the affected cylinder which was filthy with crud all over it.

My car is a 2010 so the warranty is long gone. Still its giving me a chance to throw in SLS Black series valve buckets, straight pipes, bigger throttle bodies, and phenolic spacers. Too many of the damn bolts thought are one use only and take forever on shipping.

silverstar11909

did eurocharge take any responsibility? As you changed to their injectors and the bent rod occurred?

CaptnCharisma

I don't hold Eurocharged at fault at all. If anything I made a huge error that day from what I thought my misfiring was caused by a bad spark plug for whatever reason and thought I fixed it and then proceeded to drive on it the rest of the day as I got ready for a road rally. If I could I would actually hold Mercedes accountable for not recalling the old style injectors but no way would I win that battle being out of warranty and mods all over my car. I ****ed up and should have noticed that my engine oil had 2 gallons of E85 in it and was probably pre detonating whenever the engine got hot enough or at WOT. Expensive mistake, lesson learned. The silver lining was that I was going to open up the engine anyways to do the head bolts so this kinda hurried it along.
