i want to tune my car on e85, i heard it can be bad on fuel lines, tank etc.

i have 555cc's in might car an hope to push around 300rwkw with them on e85.

but would i have to upgrade them due to e85 needing 30% more flow capability than PULP?

so goes the theory, however i would be interested to see the consumption and duty cycle figures of someone who keeps the same injectors and boost level, and literally just involves a retune to calibrate the ecu for the type of fuel... before and after would be excellent, esp if we can get a gas analysis report along with the air/fuel ratio

i think the consumption is around 30% more too, but some solid results will tell more

just to give you an idea of the extra duty cycle my car seen between e86 and pulp.

injectors are 90lb bosch ev14 (about 950cc) 044 fuel pump.

PULP tune 20psi 275rwkw 47% injector duty cycle.

E85 tune 22psi 334rwkw 90% injector duty cycle.

this is on standard rail pressure so there is more in the injectors with more rail pressure.

so in otherwords i need 800 or 100cc injectors?

you might be able to get away with them but would need alot of rail pressure. would be best to ask adrian (180or200). if it was me i would try to tune it on the 555cc just to try and save the $800.

if in any case you need injectors, ive been able to import US injectors for sau members before at the cheapest price avail (depending on exchange rate of course)

luke got 1600cc injectors or something ludicrous, chad got 1000's, and i think matty got 700's if not 555's along with dion

my 575's are running great in my engine. however i have other issues that need fixing (wont go OT)

if you need 30% more fuel and u get 30% + more power I would say its a practical upgrade, as you're sacrificing range for power (assuming the fuel tank wasnt enlarged).. its an unavoidable trait with e85

incidentally, some environmentalists are claiming e85 is dirtier than p98 oct. this is true in a sense, it develops more soot, however the soot is heavier than air and it makes its way into the soil. Studies done in the 80s which compared unleaded and leaded fuels found that in the long run the leaded fuels were better >for air quality< than unleaded as the lead oxide would cause the element to sink to soil level and be absorbed in the dirt

obviously, this is a bad thing for farmers, and anyone who deals with soil of any sort, however it proved that a heavier element would be more environmentally friendly than premium 98.

e85 by products actually are heavier than premium - they form a soot which sinks to the ground, but from what my limited understanding about petrochemicals entails, the carbon sinks into the ground and gets absorbed from the atmosphere the same way the old leaded petroleums did.

Of course there is also a multitude of environmental concerns regarding ethanol based petroleum, I think it will come down to being able to efficiently generating the substance as a by product rather than actually consuming more electricity than it puts out via its distillation process. (Not an issue if we have nuclear power stations and cheaper electricity but since we're a bunch of backward mofos we cant really expect anything great)

E85 - Awesome in theory, but some fundamental issues need to be addressed before we can expect it to be common enough for daily use.

Wicked for racing but. Just as indycar (they run methanol but hey, its not that much different)

I dont want to get into a debate here, but will say this, I dont like how the yanks make e85 with corn crops, thats just wrong, I do like how csr use a by product.

I cant argue about the soot as I havnt researched that, I would be suprised if there were any elements worse that unleaded, Unleaded is a disgusting fuel! one bonus about running E85 is it burns cleaner and doesnt leave the rear of my car dirty, unlike 90% skylines around. Check out Guiltoys e85 thread, he took his car in for emision tests in NSW and passed easily, running 330+ Rwkw from memory.

As for a injector duty, pound for pound 30% duty on a power fc sounds about right. But who wants to run same boost!

E85 tune 22psi 334rwkw 90% injector duty cycle.

this is on standard rail pressure so there is more in the injectors with more rail pressure.

I'm not after the 85rwkw that Krishy was talking about - I'd be happy with going 273@18psi up to 310-320@20+psi

700-750cc injectors see how we go.

Yeh I got my 1600cc off Dohmar. After reading about that guys 32R which maxed out 1000cc injectors at 23psi I thought I would rather be safe and go with these big sprayers.

they do make you a sad panda at full boost tho =(

but i'm so close to getting on to e85 myself, car has been rebuilt with it in mind, just need some new coils and it should be interesting to see what it makes =)

why do u say they make u a sad panda at full boost?

are the injectors dohmar gets a direct fit or do they need mods?

might hit up 1000cc to give me room with e85

even thou i have 740cc atm..

theyre direct feed low impedance top feed denso style injectors

so if you have an rb26 then yes, they are a direct fit

they also come in 1800 and 2000cc variants

-D

Only thing i dont understand is, when they said the 1600cc are direct bolt in, the info on the bosch website say they are 14mm and therefor would not fit in a stock gtr rail, being 10.5mm :s

    • Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣
    • After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.  
    • For race cars, this is one part where I find having the roll cage bar having gone through a hole in the floor better than the build it up on a ledge inside... The Merc I help on, the main hoop ends are marked on the car, and the jack is marked... Jack goes under a few inches and lifts one whole side of the car up... Removes that fight for long slim jacks for race car duties!   My biggest issue for the daily drivers I work on, is my jacks don't go high enough. The jacks start out on a few blocks, jack it up, then start a second jack under it on more blocks, and then I can get an axle stand under it. My axle stands are presently in use, and are nearly fully extended. The car is sitting with barely more than a cm of clearance to get the wheel off the studs! Sarah's Kluger is the same, as it has an ungodly amount of droop available in the suspension and a distinct lack of good jacking points!
    • Happy? Yep, my to do list is getting shorter and shorter. Either this light approaching is the end of the tunnel, or I'm about to be hit by a train... Ha ha ha   Also, Duncan isn't that far out of town that you need to make a multi day drive out of it. 😛
