Hi all

No flames please

I've trying to do a few burn outs in the RX-8 but for some reason the engine seems to cut out...

any reason why the engine is doing this?

Thanks

TSC and DSC.........:D

takahashi

Agree! :D

dannobre you are in the Pacific Ocean are you

timbo

Yep, make sure you have turned it right off ... and are fully aware of the costs of replacement tyres

Definitely on Land......Closer to Toronto

chauman

Thanks for the response

I do turn then both of them off, when ever I want to go a bit harder...

timbo

But have you turned them fully off? See Taka's amazingingly useful link

chauman

Yep, I see the slipperly sign come up and the DSC saying off...

takahashi

Hmmm

"Taka's amazingly useful link".... :o

I guess after 3700 posts, there must be something useful :p

BTW:
I think this is the most important point of my sticky thread :D

timbo

Ok then, so does the engine cut out -- as it will after 9500 rpm? Or does it bog down, as in sound like it is starving for fuel or spark? If the latter, then one would expect to see the engine warning light come on.

Certainly, in track work I have experienced the cut out as the engine hits the rev limiter, and also if you have less than 1/3 tank of fuel, which probably relates to the fuel pump pick up point

I think I will quietly withdraw from any more technical comment on this as, IMHO, burn-outs are possible the most pointless activity one can do with one's car. But, as I stress, this is just MHO

PS: Taka, of course, many of your, what! 3,700 posts!! have been useful and informative, but none moreso than that one, and yes, the wife/GF/partner one should be No 1. In fact, that sticky needs a bit of editing, eg, be specific about the Mazda oil now being available and its grade

Gibbo

If the engine light does not come on then make sure you have more than 1/2 a tank of gas. The equilising pump can have trouble sometimes due to the two part tank and therefore starves your car of petrol. I have only noticed this on the track cause I don't do burnouts, however it could beyour problem.

You need the slippery car sign on all the time. If it is only flashing on and off mid burn-out, you don't have the traction control (TCS) disabled. Hence it will cut power if you get the wheels spinning enuf.

Go the DSC/TCS full OFF mode by holding the button down for greater than 7 sec.

One other possibility - your car's not an automatic is it? Something completely different could be going on.

Burnout's rock!

No they don't, smoking kills.............. your tyres and tranny. :p

Completely pointless IMO.

Burnouts are extremely useful. You need to do them to get maximum traction for a launch.

So chauman, what is your procedure? It might give us an incite into why it isn't working for you.

Cheers,

what's the difference between turning just the DSC off and turning it off to the point the slippery sign comes up?

aggietiff28

I am totally not good with technical stuff, but I seem to remember that when people dyno the car, they are getting really low numbers because of the computer chip changing the gas flow and torque, etc. in order to save the engine of the car. It can sense when all four wheels are turning, downforce, etc. Maybe the engine is shutting off at a certain point to save the tranny, etc.

takahashi

There is no documented difference but I see it this way, after seeing a few videos and self experimenting on the race track.

Turning DSC off half-way: Turning the DSC (traction control) off only. You still have EBD and ABS. You are will oversteer slightly under braking and will power out as per normal (non-electronic assisted) cars. But you will not spin out underbrake coz you have EBD.

By turning DSC all off (with slippery sign): You turn the EBD off and all other little gadget and leaving the ABS only. So there is no electronic assist equipment and seems to be most fun as you can drift by changing the weighting of the car (you cannot do that effectively with EBD inhibiting such shift in weight).

chauman

Yeah I do, I hold the button in for the required time and see the sign up all the time.

No it's manual...

Taka's explanation of the DSC Off and "Off-Off" is sound, IMO.

Chauman, what actually happens? Does it stall before you get wheelspin? Does it stall once you get going? What RPM are you holding? Have you used any water to get them spinning, like at the drags? Are you trying to line-lock the brakes?

And additionally, you can do a decent burnout with the DSC just on the 1st stage of off.


Cheers,
Hymee.

This was posted by Maolin34 in another thread. Who knows if he's right or not, but it's another theory on how the 2 stages of "DSC-off" work.

Quote...

It is a common misconception that traction control is all about preventing tire spin....this is true only to a certain extent, especially with late model sports cars. The traction control is triggered by several different things.

1) Throttle Position: If your not hard on the gas, and the tires slip TCS will assume its slick.
2) Traction/Engine Load: If the load on the engine is above a certain point, then you have sufficient traction, and the TCS will allow wheelspin to improve driver control of the attitude of the car.

DSC (Dynamic Stability Control) would have stopped your slide. DSC takes into account, wheelspin, lateral movement, throttle position, and steering angle to trigger the system.

Aside from not doing this on city streets where pavement conditions can very way too much...be prepared for the tail to step out when the DSC is off. TCS will only step in during straight line acceleration, and only when the limit of traction is low.
