My B16a Dyno

yeah 13.5 is pretty lean... it does depend on what fuel your running too though...

ehh.. i m quite a regular Shell Economy user here.. once awhile i use Shell VPOWER.

u do have shell over there right?? :swt: out of topic. wat time izzit over therE? its 11.04am here.

okay back to business.. so.. wat do u recommend my AFR to be?
my place here is quite hot n humid. Kuala Lumpur to be precise.

Yes thats true...

moon, what octane is your daily pump fuel? Never tune it with octane booster unless you'll be using it every single time.

I remember you said your from malay, you never get cold air there do you? haha. 13.5 is not good for you. I'd stick between 12.5-13AFR for optimum balance between protection and power.

 

[moon*]

ehh.. i think its a 97ron.. gotta check again

yeap i m from malaysia. usually in the morning is cooling, but when its noon. hell its burning

have u heard of DYNO TAB? those are consider octane booster right?

i got it free. so jst using it currently.

so during dyno tuning. i should tune without using it right??

Yes thats true...

[EK9turbo]

if you need a cheap octane booster you can use tolulene or Xylene

not sure, i think it was 3am when i typed that... im usually tup till 530am!!!

 

[moon*]

ehm... havnt heard of the brand over here..

dont tink i can find it here

woah.. u a owl or something ? lol.. no need sleep ?

not sure, i think it was 3am when i typed that... im usually tup till 530am!!!

 

[EK9turbo]

tolulene and Xylene are paint thinnner bases. They raise the octane rating and the flashpoint of the fuel. The old turbo F1 cars used to run on what they called 'ROCKET-FUEL' which was just tolulene 75% & heptane!!! ..and at the end of the F1 season Honda's 149Xcc V6's were making over 1400hp on this stuff!

For every 50 litres you would put between 1-3litres with regular fuel..

But as with any engine... it depends what octane its tuned for, putting lots of additives into your fuel to raise the octane rating (and the flash-point temp of the fuel) doesnt do anything if its more octane than the motor needs.! you just lose performance then.

we've got dynotabs here, they don't have a good reputation here. I used to use them just to try it out. But didn't feel anything. The liquid types are good.

If your using STOCK ecu, then you should get close as possible to 100RON, as thats what it's tuned for.

If you've already got a tunable computer, just tune it the fuel that you will ALWAYS use. And make sure you stick to that fuel grade. It affects timings and could either make you run RICH or LEAN

basically, if you've tuned it running 95RON and you drive with 100RON, your loosing power and running RICH. And if you tune it with 100RON and drive with 95RON, youd be running very LEAN.

Are you sure 97RON? Since when did Malaysia get such high fuel grade? We got 98RON here and 100RON in sydney and melbourne. Fuel is so Fvcking expensive right now...its not funny.

lol you alright blinx?

I don't even know whats going on now. lol

 

[moon*]

ehh.. i nede to check again if the petrol i use is 97 ron, but the other shell VPOWER here confirm using 97 ron..

we've upgraded the oil recently..

Not sure if thats true... RON is just a measurement of resistance against detonation after all.

Higher RON just means you'll be able to run lean without detonation, but you'll still get the associated overheating and lubrication issues from the lean mixture. The O2 reading however shouldnt be affected by RON?


But 155whp is very impressive for a pretty much standard B16A. Which shop did you use?

From Malaysia also.

Yes it IS just a measure of resistance against detonation but dont forget it affects timings. So you loose power there.

 

[JayH]

Yeah what i meant is it wouldnt affect the fuel mixture being lean or rich.

 

[jugbugz]

well if your using an ecu thats tuned for 100RON and your using less than 98, you'll just run slightly lean. But 97RON is fine. Below 95 isn't good but all can be fixed with a fuel pressure regulator

 

[moon*]

hehe kool from mas as well ah?

i did my dyno @ N1 Racing

thanks for the headsup

ehmm.. i'll hoping to get my ecu management later on to fine tuned my settings

well if your using an ecu thats tuned for 100RON and your using less than 98, you'll just run slightly lean. But 97RON is fine. Below 95 isn't good but all can be fixed with a fuel pressure regulator

Sorry to dig this out from the past, but 155WHP from a B16A with minor mods and incorrect fueling.
I highly doubt it.

155 Flywheel power more like it.

^^Nice first post mate, good to see another friendly member...

^^Nice first post mate, good to see another friendly member...

Thanks Jokeshopbeard.
Nice being here after getting my EK4 SIR from a friend. I had a EF9 so did not quite blend in with the crowd here, but the tech all applies.

Mods to the EK4:
P&P CTR head + ITR cams (why I do not know)
Skunk2 intake manifold
HKS cam pulley
ITR throttle body
5-Zigen 4-2-1 manifold
Mugen backbox with D2 mid pipe (2.5") , decat
Kaaz 1.5 way LSD
Spoon calipers
Tein Flex suspension (F-9K, R-7K)
E-manage (blue)
Large radiator
K&N panel filter

The power which I got after tuning was 168HP, i wish it was wheel power but I am thinking more like engine power. The B16A2's here standard form dyno around 140-150HP (flywheel), the CTR's dyno around 155+...

Anyway, I am going to tune it more because the e-manage blue does not doe it justice, the rev limiter is set OEM at 8200rpm and the power is still rising when the rev limiter cuts in.

Dynos vary all over the world.
My cars figures are;
EK9 123whp
DC2R 133whp
DC5R 143whp

Probally because i'm in the southern hemisphere and using dyno dynamics. EK9 on dynojet read 137whp.
