This is from mellon racing website:
Watch out for gunk on your injectors when using e85 fuel We all know by now that you can run much more boost/timing with e85 over regular pump gas and thus create much more power as well. What some people may not know is that some gas stations re-use old diesel tanks for e85 rather than putting new tanks in ground. Some of that old sludge can get into your fuel system and clog up the injectors. There have been other theories as to what causes this build up which suggest it's just a flaw in the way some refineries create their e85. Our own Mellon Racing evo blew a head gasket due to a clogged injector which damaged the top of the block and bottom of the cylinder head so here are a few tips to help you prevent this problem: *Pull the injector rail and inspect the injectors occasionally *Load up a pump gas tune and run a tank of regular pump gas through occasionally to help clean them up. *If you do find sludge on the injectors send them off to be professionally cleaned. attached to this article is a picture of how many q-tips it took to remove the sludge from the injector nozzles before sending it of for professional cleaning.

this is the one shell gas stations will be selling

So this does not pertain to ID 2200.. This can happen to any injector. So your point was ?
|
This is also another good read E85 Injector Build-up / Gunk - Page 2 - NASIOC
So running pump gas every now and then will clean things up. |

So do you have proof ? I have talked to Paul yaw about this and he finds the issue be in the fuel system setup.

Zeitronix ECA : SEMA Award Winning Ethanol Content Analyzer and Flex Fuel Sensor for E-85 and E-85/gasoline Blends Its easy to add methnol... We tuned the car on e78.. That's what the analyzer said... As for premix I use castor 927. That zeittronix says you need to use a gm flex sensor, are you saying the haltech does not require it?.

We know what happens and what to expect people keep linking that one story from that one shop but where are all the thousands of people who also suffered engine failure soley based on sludge in their fuel???? Running a bit of regular unleaded is probably not a bad idea, i try not to store my car with e85 in it but i have and rather then a ethanol sensor ill just check out a AFR meter to make sure things are normal. |

You know how many cars are using e85 and the new style bosch injectors?? Go to any car forum they are all using them.

yes heaps and not everyone has problems, I know people running 2J, RB26 and have no issues but every rotary I know that tried them have failed - looks like that link is down ATM but they say is possible issues with heat so could just be layout of turbo and injectors on a rotary that causes the grief, just giving my experiences, by all means try them and see what happens.
How many local rotaries have this problem? is there an australian forum we can read up more on this? |

Just an FYI,Haltech does not need to use a GM sensor Haltech – Engine Management Systems » Blog Archive » Sport FlexFuel Sensor Support I dont know who actually makes the sensor for Haltech but it is not the same as the GM sensor. If you are already using the zietronix setup you can configure an input on the ECU for the ethanol content using a 0-5V signal and keep using the GM sensor. What is nice about the Haltech sensor is you are able to eliminate the zietronix converter box. |

No.. I said I'm using a flex fuel senor... look at post 59.

I know Haltech has their own set up, he was saying he uses the ziek unit, bit confusing the way he worded his response because the ziktronic NEEDS a GM flex fuel sensor

My question to you is what fuel pressure you are running and what is your max boost? I'm also in the upper 400 horsepower range...
here is vid of mates - now old set up 430KW ~585HP @ wheels - 60 psi base, lots of boost |

Was that static or rising rate? The reason I ask is because of the Delta p theory.
Fuel Press and Manfld VAC/Pre Interface - Tech Corner I run a static pressure of 56psi. So if you take your max boost level minus your fuel pressure, you should have a minimum of 30 psi of constant pressure to overcome the additional pressure surrounding the injector nozzle. So mine would be 56psi of fuel pressure minus 20 psi max boost equals 36 psi Delta P... More than what I need but it keeps me on the safe side if I have a spray pattern issue... I hope that explains the injector issue that you keep talking about.. Here in the states we have no issues with the injector dynamics (id2200). Thats Robert P.S. Nice car!!! |
^So you do not have a vacuum line connected to your FPR? Why would you want a low fuel pressure? You will end up with poorly atomized fuel.
Almost all turbo cars use a 1:1 boost reference so the pressure differential is always the same no matter if the car is in vacuum or under 30PSI boost. Rising rate increases pressure differential when boost is seen by the FPR. |
This is another write up on injectors and about the Delta P..

Cheers :) is rising rate FPR, cool not sure maybe is different race fuel mix or something?!?! all I know is mate has sponsor for injectors and they have officially given up with id's lol will keep eye on thread to see your results :)

8 hours? Going to disagree with that, never mind how broad that statement is

Below is the official statement and contact number to see if E85 counts as "alternatively powered" and how to get your car certified. My take is that "do not currently require" implies that they may test them in the future.
"** Hybrid electric vehicles, such as the Toyota Prius and Honda Insight, and other alternatively powered vehicles do not currently require emissions inspections. For further information on exemptions, call your county motor vehicle office, or the Colorado Division of Motor Vehicles' Emissions Program Office at 303-205-5603. Also see information regarding vehicles manufactured outside the U.S. and kit cars" Air Care Colorado :: Exemptions So, officially, you are not emissions exempt if you convert to E85. Which is odd, because I found a few stories of people who have converted in the past year, but are now emissions exempt. I wonder if certain DMVs are doing the "wrong" thing and somehow making the vehicle exempt even when they shouldn't? Oddly enough, the effectiveness of the Colorado emissions program was just audited, and the audit suggests that the program be disbanded: Audit: Scrap, or roll back, long-loathed vehicle emission testing | Colorado News Agency End of road for Colorado's emissions tests? - The Denver Post |
