track problems...?!?
 

hi, i was doing my first solo1 at a local karting track and even though it was a good experience i had a lot of trouble with the TCS or fuel cut...

first off i have an 05 gt 6spd rx8 with Racing beat sway bars, REVi intake, Agency Power exhaust (stock midpipe), Mazdaspeed springs, 265/35/18R 245/40/18F tires on 8.5 and 9.5 wheels...no TPMS

the car behaved really well better than i expected but i had this weird cut off like a fuel cut in every sharp turn and also in the straightaway i tried to run it with the DSC on and also off but it didn't make any difference the car just shut down and the throttle went blank, it was dangerous and also worrying i tried searching and found something about disabling the TSC completely by pressing the DSC button for 7+ seconds and i didn't knew that but none of the problems explained by the members seemed to be the same as mine... the car had a 1/2 tank of fuel so it couldn't be fuel and the oil level was Full...

if there's a thread about the same problems just link and i'm sorry but i couldn't get anything while searching...

thanks in advance...

You were probably running out of fuel. In high G turns you need AT LEAST 1/3 tank to be sure you will have no problems


You might also have a poor fuel pump if it is happening at higher fill levels

ask me how I know ;)

i had 1/2 a tank of fuel which actually is more than 1/3

When mine was doing it in High G left turns......It would do it with 3/4 tank. I added a second pump...and replaced the OEM pump. When I use the new OEM pump alone it is OK to almost a 1/4 tank...so it tells me the OEM pump wasn't working...despite the dealer telling me it tested OK

I have a switch for the second pump and run it at the track. Since then I have had no fuel related problems.

On another note...if you have a failing coil you will trip a lot of missfire codes 0300 series....

It's the DSC switch. Happens all the time if you don't hold it long enough.

Hold that switch for 7+ seconds.

ok, i get that if i hold it for 7+ secs i disable the whole system but why does this happen only on the track and not when i drift on the street???

I had sympathy for you, but now that you mentioned drifting on the street I would reccomend you sell your car and die in a fire

BR82, don't hold back. Tell us how you really feel. :cussing:

:rollingla

it's not street drfting actually i dont like drifting as a "sport" i find it stupid

what i meant to say is that it didn't happen when you took off a turn or any stop and you loose traction(drift), it didn't even happen to me one day that we took the car to the dragstrip...

Drifting is controlled understeer. If you're getting understeer from a stop, you have biiiig problems.

it's actually done purposedly but anyways let's get back to topic... and btw: drifting is controlled OVERSTEER...

this thread fails

it has to be fuel starvation. Though it should not be happening when there is more than 1/3 left in the tank.

I was running at the weekend, and the fuel starvation did not kick in until just about the time the fuel light would come on, and yes it was high g left hand turns that did it.

I have a 06 by the way.

personally I wouldnt run the car so light on gas that the light comes on, the gas cools and lubes the pump too, so running the pump out of gas can't be good for the actual pump itself

It's a 4 wheel drift, where neither front nor rear tires have traction right (overcoming both slip angles)? That is called understeer. Only the most set-up drift cars have the ability to fully turn the front wheels into the direction the car is going through modified body work and steering racks.. and even then, not all the time. Breaking traction with just the rear wheels isn't drifting, it's powersliding.

Gee... if that doesn't describe 'the sport drifting', I dunno what does.

You learned something new today. Or will you just ignore it? Probably the latter.

Heck... go rent the 1st season of Initial D. It's covered in there. ;)

BlueRen for president! :patriot:

I actually started the day with a full tank, and the second I got the first hint of fuel starvation I pulled in, and topped up (brought a 20l canister), so no harm done there.

Excellent advice though blueren.

you sir will be my VP
:patriot:

Just be careful on our hunting trip. :ar:

lol--walk in front!
I too had fuel starvation in high G L handed turn--but only at high rpm fuel demand. It was 3nd gear at about 8K, dropped to 4th and 6.7 K or so and the problem went away. Had over a 1/2 tank of gas. New OEM fuel pump? Hmmmmm. Never thought the oem would not be good enough.
Thanks
Hey Red Devil we miss yall down here!

Don't you guys do a NASA event at Road Atlanta in March, or somewhere around there?

I've been scheming how I can transport myself down there so I can get some track time in during the winter.

Road Atlanta is an awesome course. so much fun falling off the earth in that last turn!

OD is great people.
