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

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.

Only what I've seen happen to mates cars, these are dedicated track cars making 400+rwkw with proper fuel setups not some budget streeters- although interestingly it seems mainly only rotors that seem to have majority of problems but I would still avoid

Some light reading...

That zeittronix says you need to use a gm flex sensor, are you saying the haltech does not require it?.


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

This is the station they are fueling from, and i expect a bit of a single case. Not all are converting diesel tanks, all the stations here sell wayyy more diesel then they do E85. It will clean your fuel system so if you have a dirty tank or lines it will clean them out.



This is not new stuff, people been running it for YEARS now. 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.

crazyboosta

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.

I am using the gm flex fuel. Im just not using it to change my map.

We have a alternative fuel section of this forum, I would like to think that if people had issues they would have been posting about it and it would even be a sticky if it were a issue.
How many local rotaries have this problem? is there an australian forum we can read up more on this?

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...

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.

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

"I'm not using a Flex fuel sensor.

I can with my Haltech P1000...

I decided to use this analyzer.

iTrader: (23)

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

Yes it was worded poorly, I figured you knew what you were talking about.


I just wanted to clear it up for some other people and let them know it is a simpler setup.

Rob XX 7

iTrader: (8)

yes we have that cleared up already

crazyboosta

here is vid of mine making 320KW ~ 430HP @ wheels - 40psi base fuel, 17psi boost

here is vid of mates - now old set up 430KW ~585HP @ wheels - 60 psi base, lots of boost

crazyboosta

there is heaps of info out there, this is screen shot from link I posted before - works on my phone but not laptop?!?!?



look up triple 8 racing if you don't know who they are.

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!!!

RENESISFD

iTrader: (13)

^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.

Different tuning technique. Im not a tuner but we have been running this way for years with no issues. If you read the write ups you will understand more why we run without the vacuum line hooked up ( static )...

crazyboosta

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

Gave em a call at the 303-205-5603. The guy I spoke to told me "if it burns, we test it. Ethanol, natural gas, anything". They don't test hybrids because they are unable to reliably bypass the battery and have it run on the engine for the duration of the test.

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:
