*****************NEWS FLASH***************** Just for yucks I looked into the injectors today and they seem to be available for a somewhat reasonable price again. I will do $470/shipped for a set. Brand new genuine Bosch 550's. Lemme know if you need them

Thanks!

Dave

P.S. Gonna copy and paste this on the other GB as well.

xela

How much are you trying to let the kit go for?

Well then you know what to do Dave, send over the PayPal invoice.

E85 kit has landed! Stoked to get it on the car. NOTICE!!!!- BE CAREFUL opening your boxes guys! My wiring loom was packed on the top of the box, and I have an tendency to use very sharp knives to cut packages (Shameless plug for Spyderco here) ...thankfully I did not nick the loom. This PSA has concluded.

DavesMeanE's

Stoked for you bro! It's gonna be good times

Thanks

Injectors shipped today

Thanks!

Ya it's too bad Oh well! Good news is there are still low mile cars around for when you get back! Just did a bunch of service on a 2009 w/ 13k miles on it! Crazy...

Have fun in Japan

Thanks

Crya - How was the install? Let us know how the drive in goes after you get the good stuff in there

Thanks!

Install: I'm a fairly novice mechanic and only had the car since January. However, when the OE injectors were on sale a few months back, I went ahead and refreshed 'em. That process gave me the ability to get on top of the learning curve for install here. That said, install was as simple as can be, not accounting for the tight spaces trying to release the injector plugs. Watched your vid earlier in the day, got the kiddos tucked in and headed to the garage at the end of the night. It was late and hot here so I took my time double-checking all the connections and the new fuel line. It all fits together perfectly. I followed your orientation of the fuel line and module and it's great tucked back in there. Once I was satisfied I buttoned it all back up and cranked her over. She hesitated until fuel came back in the line and then boom. Roaring again. Ran it at idle trying not to wake up anyone and fuel lines showed no leaking. Said goodnight.

Filling Up:


My needle was at a hair under half tank. I managed to get 11 gallons of E in there. It took a few minutes tooling around before the monitor maxed out at 55% E. I just cruised into work and will await a full fill-up.
As for the App, well, it is what it is, an ethanol monitor. Seems like the developer could do more with it like "the other guys" and show injector duty cycle, I think that's what it's called.

In closing, while it may not be for everyone, I'm very excited with the kit. Everything fit. The looms and connections are all top quality and well thought out, and well laid out with enough slack where you need it.
THANKS DAVE.

Is there an available app to see injector duty cycle? Is that necessary? I don't have headers but with ROWs and 2nd Cat Delete I see another member was at 85% duty cycle on about 65%.

Sakebomb

Agreed the ProFlex Commander app really sucks compared to others out there. Im still trying to figure out how to show injector duty cycle with OBDLink or Torque pro.

SactownP31

Ok fellas now I'm starting to get a little thrown off here as to why most mb world member have some sort of "data lust". Whats with the obsession with knowing all these "numbers". If you're a tuner, sure I get it, but the rest of us, c'mon now.

Not sure. Speaking personally now that I'm running E85, I just figured I should be aware of how hard my injectors are working since I have stock ones. I don't know what 99% of the readings would mean but I'd have this forum to help me decipher and learn if ratios and trims and all this other stuff people are complaining about were popping up. Like there's that whole thread running on long term fuel trims and ROW boxes and whether it's good or bad or what.

Dave clear some space for PMs.

Some of the numbers people are trying to monitor are important. With OEM injectors, duty cycle is one of them. A long standing "rule of thumb" regarding fuel injectors was to not exceed 80% duty cycle under full load. You start to run the risk of being unable to deliver enough fuel under certain conditions. For instance, if you were to get a batch of e85 at the higher end of ethanol content, you may not be able to provide enough fuel under load to maintain a safe AFR. Similarly, if injector flow decreases over time due to build-up (not uncommon at all), being that high in duty cycle reduces the available "headroom" for the ECU to be able to compensate by increasing duty cycle.

To me, this is an important number to monitor since the OEM injectors are near the edge when using E85. I'd be far less concerned with monitoring this if you already have upgraded fuel injectors/ fuel system.

I believe that the Torque Pro App does display duty cycle, but I don't know if the information would be relevant when using E85. I imagine the E85 controller works by increasing the injector duty cycle signal received from the ECU as necessary for the measured ethanol content.

Consider the following: Let's say at a given ethanol content, the controller is programmed to increase duty cycle by say, 20%. Based on engine load, the ECU is commanding a injector duty cycle of 60% for the fueling needs of premium gasoline. The OBD2 system would then report this 60% duty cycle as received from the ECU. However, the ethanol controller received this signal, and adds the 20% additional fuel by increasing the injector pulse by 20%. As a result, the true injector duty cycle would be 20% greater, or 72%. Therefore, you'd really need to see duty cycle at the controller itself.

Dtorre1240

Yes, this is correct. The Torque Pro App does not know that there is controller upping the duty cycle between the ECU. Yesterday I checked to see if the Pro App had duty cycle monitoring and I did not see it. Personally I am monitoring mine with the EFlexFuel App via Bluetooth. But I highly doubt that the EC version could connect to that. If there is a way to measure duty cycle via OBD2 the value that you will see will probably be the "commanded" value. What BalanBro said is correct, what is relevant is seeing the measured value from the controller.

I think we are at a point now where a substantial number of people are using some kind of flex fuel kit on their car and the topic of oil change intervals should be discussed.

Has anyone had an oil analysis done yet after a few thousand miles? I have about 2800 miles since the last oil change with liqui moly of which 2000 of those miles has been strictly e85. I might be due for a sample rather soon just to see the numbers.

Anyone know the tolerances on this motor? Are they considered tight or loose? If tight maybe we can get a decent interval of 4000-5000.

We really have to find out if our cars are diluting the oil and these intervals need to be drastically reduced

These injectors are a "long nozzle" type, just like the OEM bodies. The STOCK connector is very unique and there are no injectors that use it in the aftermarket (as far as I'm aware). Google "EV1 connector" This is what I have. You can also potentially get injectors with a "USCAR" type connector. (also just Google that word to see it).

Best option is to cut and solder on new connectors in the style you need, as opposed to using an adapter harness.

Thanks!
