What RPM do you launch your EK9 at?


Depends on the tires/ suspension setup & road condition. :)
 
7k is abit high aint it? but as said depends on setup.
I find that a 3.5k launch offer good amount of traction but thats dc2r
 
have you taken advantage of the launch control feature that the stock ecu provides if tuned?

I dont think theres a launch control feature on the stack ECU, unless you tuned it by CROME or whatever...
 
yes i actually mean that stock ecu supports this feature if you chip it, which is really useful.
 
How come more people do not 'chip' the standard ECU and spend all of their money on an aftermarket ECU?

Is it not best to have all of the safety features of the stock ECU?

What safety features are you referring to? OBD2 ecu is not impossible to chip but just not worth it, since OBD2 is more advanced it will attempt to compensate and go back to the OEM program.


Anyhow i launch using launch control at about 4500rpm, nitto NT01 tires and thats without boost as turbo cars can launch with boost or without.

I launch my bro's dc2 at 4k but if you try and launch an ek9 at them low revs it boggs down and goes nowhere.

So i launch at like 6.5k, slip the clutch and feather the throttle until i get grip.
Works well for me.:nice:

becuase stock ecu is crap for tuning? buying a 'chip' is a waste of money
 
i run an AEM ecu and my launch control is set at about 4, iv got road tires on atm so this is best so i dont get any wheel spin at launch
 
Isn't using launch control just being lazy? I would of thought it would take more skill without launch control to get a good start.
 
how does launch control work on a manual car? i know how it works on automatic but on manual?

It is done by setting a rev limit when when the car is Stationary & wont go above that rev limit untill you go above a certain speed!

eg- 4500rpm limit below 10mph once you reach 10mph you will get your full rev range!

Hope that explanes it for you!:nice:
 
3-3.5K. Maybe 4 in the summer time. Stock ecu`s don`t have launch control. It`s all matter of which program you`re running, regardless of ecu.

yeah i get what you mean. cheers for that
 
B16B i used to launch at around 5500rpm and found it to work pretty well as before that rev it would bog down quite a bit.

With the B18C set up i launch around 3500RPM. There isnt much bogging down with this engine. Just picks up and goes. Rev it too much and will go into a spinning frenzy so you have to be careful. Unde-revving is sometimes better providing you have the torque lower down to pull you through.

I usually launch at about 4500, depending on road surface, there really can be so many different sequences dependsing on alot of things if you get me.
 
Aroud 5k - 5 1/2k i find to be the best. Control the wheel spin with the clutch and then you stratight into the v-tec.
