RON95 on Evo

[HBS]

who? RC51?? u sure know me then..hehehe..
i missed that bike everyday..trust me..

Dont know me eh?I the one that own arip white car....hehehhehe....

So you decided to tune your E10 for R95 compability or not?
Arip car is already EU spec so I was damn lucky...minimum asking for R95 hehehe...(but just like you its was a weekend drive only so because I rarely ever driven the car I always pump out the best for her...sometimes only I use R95)

Hmm good discussion & test-based opinion...

BTW,I just got one question.If the stock ECU is already out from factory with RON95 minimum octane as stated on fuel cap,then if somehow I reset the ECU for some work,would the ECU need retuning as well to get the factory setting of RON95 minimum octane requirement or the ECU would reset to its best setting available(Like RON96-98 after ECU reset?)

Sorry for a complicated question but just need to be sure about this as I taking off all the batery last week for some minor check-up for my car.

Or better choice,get back your RC51....

no problem with the ecu resetting as it will start to adapt to your new settings better
at first what i notice when my ecu gets resetted is the fuel mixture is rich and ignition timing is retarded i guess these are precautionary measures taken by the ecu before it adapts to the new setting of the car so after a while of driving the ecu should learn and make the appropriate adjustements but there is only so much the can do you would need another engine management system or piggyback to really fine tune the a/f ratio and ignition timing to get the absolute best results from whatever mods you do to your car to me something as simple as changing to higher grade fuel also can be considered a mod because now you can advance the ignition timing more and get better horsepower at the same amount of boost if you are running a turbo engine
the same applies for N/A as well except for the boost part

HBS,oh its u bro!
I want to have a ride in that NSX sometimes..always been one of my favorite all greats!

i dont think i want to tune my car for 95, i bought it for a fun drive..so i might as well use it for what i bought it for.

No hal bro....but I was slowly replace wear & tear on that car...so far the progress is slow(as the part are rarely ever to come by & most of them are need to order from USA & less likely from japan due to lots of tuner/specialist for NSX are always around north america)

Even so I can say the NSX are "driveable" regarding the condition.Sure it got lotsa thing to be replaced but since I bought the car from arip,just 2 week after that I going to Kedah & stucked in massive jam for about 3 hours but so far the car didnt have any sign of overheating or whatsoever.
So I can say the car getting even more healthier by now as I have changed the prime coolant hose,new bushing & tie rod,new strut & latch,new toe link & readjusted all the aligment on all 4 tyres....so the next might be the coilover & if you know where to re-wrap the steering,I was happy to hear your recommendation.

i might try using ron95..cause americans doesnt have ron 95/95..they have 91 and 93, but they are running ok.. maybe i ll try few tanks and see how it is. But, im still doubtful regarding 95.

but since i have 2nd small car, i dont really need to bother about 97 unless im going for a weekend drive or tracks. when that happen, im not suppose to worry bout the fuel prices..

im interested to know either should i use standalone ecu to tune my car for 95 or just hoping the stock ecu will cope with it. 5% powerloss is not much a difference in term of percentage, but when you have 300hp, 5% loss is 15hp..thats a lot actually.

Err actually there is a difference
Local Octane Standard=RON
US Octane Standard=RON + MON/2
So US octane 91 is more or less equal to 97 octane there already

 

[pengyu]

oh ok..i dont know that.
and they also have E85 which much better!

either way, we're getting screwed with the inflation while the salary is flat for years..

Yeap, that's true.:top:
US RON (AKI) rating is lower than Europe and Japan (including Malaysia) RON rating.

( RON Octane Rating x 0.95 = AKI Octane Rating )
95 RON Octane x 0.95 = 90.25 AKI Octane (US measure)
97 RON Octane x 0.95 = 92.15 AKI Octane (US measure)

97 RON Octane x 0.95 = 92.15 AKI Octane (US measure)

.......I dont think there's a AKI Octane rating... The US rates the fuel by AKI(American Knock Index) , not by octane number while other regions rate the fuel by research octane number(RON)... However After all of the conversions of the two units, the user will know the value he should get.

 

[BE5RSK]

AKI rating is the average of the RON and the MON (Motor Octane Number) = (R+M)/2).

Of course AKI is not rated by octane figures. The reason I put the word "octane" was just for easy reference, caused most of us determine the fuel grade by octane number.

Thank you for your correction, sir.
BTW, AKI is "Anti-Knock Index"

There is a reason of our G losing money although we, the rakyat have to pay numbers of taxes(income tax,govt. tax, bla bla..just name it..). Nowadays,even to drink a cup of teh tarik we also have to commit the tax to our BELOVED mr G. Yeah, our G must be rich is it? But at the end, we'll hear: KERAJAAN MENANGGUNG BANYAK HUTANG..TERPAKSA KURANGKAN SUBSIDI blablabla..and the shit just goes on....which burden us,the tax payer...every consumable price hikes up,even to buy seketul bawang(onion)...and recently the hike of RON97 fuel price to RM2.90/L. The way we 'LOST' our money in Malaysia has become common and normal these days as one of these bugs daringly claim his 'right' in the court.

Read this:

One of the bug who digs out our G money...where the money should be returned to rakyat benificial of commitments to the beloved country.feel free to judge it...

gov already deep in debts....issue bonds dunno how many times already for these past 2 yrs, now even AP kings kena dig, ron 97 n sugar naik ...jz a tip of the iceberg to come...

 

[PabloIceman]

Increase petrol and sugar prices to fund the Gov's election mechanism ... They need to fill up the account again after spending that huge amount in Sarawak election ...

 

[4G93NAPower]

well you can can try RON 95 + Water/Methanol Injection to get higher RON rating with something like snow performance / AEM Water/Meth Injection kit

used the AEM Water/methanol injection + RON97 for my heavily modded satria after shell decide to stop providing vpower racing from penang, performance wise its not so bad and i gain couple horse increase :P

 

[p3jal]

ron95 will increase price later..heh

 

[DDgreystar]

I have tested my 1st tank of Petronas Primax 3 ron 95.....1st 20 km were slightly sluggish abit, however later on, it was back to business again :d

however pls take note that i run on a stock ECU with reflash; those on pfc or non stock ecu, u may still need to go back for retune; reason being stock ecu has auto retard / advance on ignition timing if not mistaken :D

 

[options]

Car got AP tax, import tax, sales tax ... road tax for big cc car also damn expensive ... high quality petrol some more keep going up ... how lah ... to fulllfil our dream to own a supercar ?? :-(

 

[Kennydydy]

who said evo cant use ron95? since ron97 going up rm2.50/l...i re tuned my E6 with power fc using ron95...couple mods with 1.5mm metal gasket + no8 cold step spark plug...with ron95 my E6 limit boost only 1.2bar/270whp..knock count 10-35..what tuner said safe area knock...they said do not up boost over 1.2bar coz more knock will occur..tune rich when boost and 14.5 when idle/cruise....now i done 10,000km with ron95..spark plugs has checking is brown colour (good a/f ratio) KL-KEDAH-KL-JB speed 140-180 constant without problems...with ron95 you must sacrifice power coz ignition was retard for prevent knock...but i am happy coz 270whp enuf for daily ride with fill gas RM 1.90/L

p/s : the best ron95 ever : petronas 95 xtra...with low knock level :wavey:

so E6 stick with ori stock run in ron 95 no problem???
coz I wanna buy a E6...now use perdana 4G63T..not enough...hehe..

Depends which E6 u buy and the previous owner use which RON else u might need to retune. If as u mention a stock stock ori E6 usually can run but test 1st dun hurt engine or other parts juz coz of using lower octane fuel. I do notice diff brand also got slight diff, earlier I been using petronas I feel my engine hotter, now use Esso/Shell temps slightly lower most obvious if when revving engine will feel jerk / ping now when change already feel smoother edi. Maybe new petronas better but I never tried yet still sticking to Esso / Shell.

That mean have to check the car condition and how the previous owner use it....
now I always using shell ron 95 for my 4G63T in Eterna...and lastime i was try to use petronal ron 95...not smooth....maybe have to let my engine recognize...coz i change immediately..at time was low no choice have to pump also...hehe...thanks for reply...my fren was influence me seriously..he also post to sales his car and get a E6 or E7...

 

[lanevo6]

Kenny if the car u buying is with Ori Ecu than you don't have to worry. Like DD said it able to learn and adjust thats the advantage. When pour Ron95 dont boost first 10 min let the ECU self tune after that you can drive as per normal.
