Tuning Your Stock Skyline To Run On E10 With An Interceptor If Necessary

[Pattey21]

Has anyone with a stock skyline (stock turbo/injectors) used e10 with a tune or by simply resetting the ecu?

Cheers Kents

P.S Rage away warriors!

lol at premeditated butthurt.

E10 will run just fine just a little bit lean =D

O2 sensor might be able to compensate on closed loop, but on open loop it would be slightly lean.

You won't make a noticeable amount of extra power and it won't have much knock protection, so what's the point?

[Trex]

Ahh.. E10 will make more power. Not less. E10 is a better burning fuel and that's why it is used in all new cars. Ask the police about their f6 and gts. They will tell you the same thing.

I didn't say anything that contradicts with your statement?

Definitely didn't say it would make less power...

Also you say that new cars are designed by the manufacturers to run on it, yes that is true, but the important word in that sentence is "new".

On an old car that is not designed to run on E10 any benefits will be negligible, like I said.

Cause ethonol = RACECAR and its 20c cheaper litre.

[Jazzadub]

Well if it's cheaper that is a good benefit, but assuming closed loop compensates for the ethanol, you will burn through a tank slightly quicker.

So the $/KM won't be much less than with petrol.

E85 is the business if you want racecar status, not E10

[Dose Pipe Sutututu]

should look at the factory timing map.. then ask yourself will E10 work well..?

if you want to run E10 you are going to need a remap, or at a minimum retard your cas by about 5 degrees.

[Blackkers]

yeah E10 on a factory timing map = ping city

[GTSBoy]

If this E10 is 91 octane equivalent (or therefore 93 or perhaps 94 octane) then it will ping. Even bloody 95 likes to ping in most Skylines. Ethanol be damned - going leaner and lower octane at the same time cannot be a wise decision.

Try it and find out.

[Ben C34]

E10 is shit.

But I suppose if you want to ping your engine to death it does work out cheaper.

Yes that's the idea.

Im currently running a SAFC II tuned to 98, which have have a dual map feature. Car is running stockish boost 9psi (makes that with wastegate pressure only) so even though the fuel is trimmed which advances the timing, it isn't enough to cause knocking.

Changing to E10 would require more fuel, so if the trimming is backed off and or more fuel added it will decrease timing. Whether it will be enough to not cause knock at load points or be achieved with minimal base time reomoved is the real question.

Also finding a tuner to attempt this and not just say "eat a bag of dicks" is another challenge.

100RON E10 if tuned properly can make a bit more power over standard 98RON, however the 93-94RON E10 that is usually at the pump is a BAD IDEA and i wouldn't even try. From what my wideband showed me, when i had my 98RON AFR's at 12.6:1 (NA back then) they would jump to 13:1 under full load with E10(100RON) but i found i could wind in a tad more ignition over 98 too.

[KiwiRS4T]

Yes thats the idea. SAFC (interceptor) can run two maps (run one for 98/E10), adding extra fuel though the interceptor will back off timing, may go speak to a tuner see if he's interested.

He may just tell me to "eat a bag of dicks"

E10 means its 10% ethanol - do all the suppliers in Aus use 91 petrol for the other 90% or does it vary? If so I wouldn't bother. E10 over here is about 98 but its still of marginal value.

Turning your CAS is not really going to give you the timing that you need.

If you want to go faster turn your boost up a couple of psi.

Borrow some knock equipment and pull back the timing on the CAS enough so there's no more audible knock.

The stock ECU runs rich as bat shit anyways, so you'll be safe with more ethanol content..

However, what is your goal?

You don't really save more money as the car becomes less economical

[sneakey pete]

United P100 is 98 octane petrol with enough Ethanol added to get it upto 100 octane. That'd give you a good benifit with a remap. Cheap wollies stuff... probably not so much.

[89CAL]

AFAIK E10 is shitty fuel mixed with 10% ethanol to bring the RON up to 91. Therefore it is no better than 91 octane, it just burns a tiny bit cleaner and is cheaper.

I have never heard anyone who has enjoyed running their car on e10. Everyone has said the car runs worse myself included when I ran it in my old VL Calais. Honestly the difference between filling with e10 and 95 price wise, only amounts to a few dollars when the tank is full.

If you cant afford an extra $10 or so to fill with 98, why did you buy a skyline?

"Unleaded E10 is United Petroleums ethanol-based unleaded petrol offering. As a result of ethanol being present, it has an octane rating of 95; higher than the 91 octane of normal unleaded petrol. Ethanol is a natural octane enhancer - adding ethanol to petrol boosts the octane number and its performance. It also helps the other components in petrol burn more completely thereby having a cleaning effect on a cars fuel system."

Off United's site.

How can E10 be 91 RON when the base is 91 RON then blended with a higher (ethanol) product?

[89CAL]

Maybe they have changed it but BP's e10 used to be/is 91RON

Either way I wouldnt run it on a hyundai getz, let alone a turbo skyline

Curiousity really, see if there is any possible benefit or if it is just a waste of time. I dont have much interest in chasing power or changing the stock setup past removing restrictions, so shit like this is my Niche.

Plus love to prove the "bandwagoners" who comment alot and know very little.
