Joeyjoejoe's E85 Tuning Adventutres

[joeyjoejoejuniorshabadoo]

ok so i finally got my car back today and decided to try this e85 everyone's talking about....

i went on a mission to hoppers crossing united and picked up 40lt for the bargain price of $39.90!!!

i then went on my road trip to my tuner, Rob @ CREATD....

car : 94 r33 gtst with an UNOPENED rb25.

turbo : HKS 2835 pro s (.68)

fuel system : nismo 555cc injectors, nismo pump

management : power fc

we first did a pulp run for comparison's sake and got 270rwkw...

then we dumped the tank and poured in the jingle juice... the first thing you notice is the smell... its sweet... real sweet...

turned the key and when the e85 filtered through the idle was pretty horrible, but livable, the afr's were off... but we gave it a pull just to see the diff off the bat without any fiddling... 278rwkw... not bad...

after a few more pulls and some extra fuel + timing we ended up with 311rwkw! :PBJ:

below is a comparison graph with pulp (green) and e85 (red)

the tune is now nice and tidy, and the car starts, idle's and runs like a dream.

the 311 rwkw is insane with full boost by 3500

traction is now non-existant (with 5/7 greddy coils, positive camber, sways etc)

so after day 1 of e85, i am a VERY VERY happy camper! i even went back and filled the car up and grabbed another 40 lt in the jerry's...

gonna run it for a full week as a test and make my descisions then... but so far, DAMN good!

below is a link to the vid of the 311 run:

BIG thanx once again to Rob @ CREATD for yet another bang up tune!!!

Very Very Nice Result

What sort of duty cycles were you hitting with the 555's?

P.S

I don't wanna rain on your parade but if you go for a run and need to fuel up with ULP, won't the car run like shit because of the different fuel?

The e85 sounds good and looks like a winner.

It's not like it'll happen everyday but keeping the boot full of jerrys for an extended run is what you'll have to keep in mind.

We don't have it over here yet but I'll be keeping an eye out for it.

Nice work Mr Shabadoo, have you tried the current tune running normal 100ron just incase you get stuck with no e85 available?

Will it ping it's ass off and be a limp home prospect or still be safe under normal driving?

Yea dude ur 33's tough, love it..

Ye its good fuel no doubt - Matt who is tuning EVO after EVO at the moment is seeing crazy gains.

Only issue's i have - its not widespread enough here in Vic yet really... and the price isn't really reflective in terms of economy.

Economy is worse than good pump... depends on the use of the car

[joeyjoejoejuniorshabadoo]

nope, just use my laptop and datalogit if i need to change maps....

car will run mostly on pulp till e85 is more redily available

yeah, so far the consumption is alright... ill post more details in a week (i ripped through nearly 40lt today )

looks very impressive mate, good results.

[180or200]

good result, how much timing did you settle on at full load and what afr?

[joeyjoejoejuniorshabadoo]

i'll grab that info when i get back to the tuner.... cant remember off the top of my head

[DaGr81]

Looks good, how long did it take on the dyno to get that result?

[180or200]

no probs, you won't gain much more up top as i think the .68 would be close to max but you could gain more midrange pushing more psi into it.

Good results, but am i reading right that you are now running more boost?

[joeyjoejoejuniorshabadoo]

yeah, i recon i could get 320 with the cam gear, but i decided not to push it anymore (+ i want the response)

it took probably 2 hours tuning.... (we chat a lot, we really only did like 10 pulls)

[joeyjoejoejuniorshabadoo]

yeah, its on 18psi for the e85, and 16 for the pulp, as the pulp tune wasn't gaining any more at that pressure

Awesome, thats what i wanted to read

[joeyjoejoejuniorshabadoo]

yeah this e85 is GOOOD stuff...

and the best part is that i have the power of a 3037 with the response of a 2835.... cake and eat it and so on

Awesome results man, and thanks for sharing - really good to see an overlay between normal pump and E85 on the same car
