Default hydra launch control

What are your settings? I just started messing with it. Default is like 94.7 fuel cut. Is good? I was gonna start at 5000, because when I set it for 2000 it really didn't cut until 2500.

I like using only fuel cut because it's smoother with less "popping" and loading up of fuel but you are limited to a higher rpm range. Launching between 5500 and 6000 rpm is really ideal from my experience but more importantly it's a better matched RPM when you "flat -foot" shift.

Experiment with the fuel and spark cut but Darthchicken's setup should work well for you. If you use too much spark cut and not enough fuel cut it's fireball city

Have fun!

Thanks,
Phil

Well the track go rained out last night, but I tried the LC out with Darth's settings on my closed course and it worked well. It was more like fireball subdivision than fireball city as witnessed by onlookers . It put me at like 5 lbs of boost. It still wanted to bog if I just let out of the clutch (not a sidestep) but it worked well when I slipped it. I might raise the rpm a little, so I don't have to slip as much, because my clutch was screaming for mercy.

Fireball city requires about 50/50 fuel ignition cut.

Leave it at the default settings and you should have 8-10 psi of boost but this takes about 4-5 seconds. With a big turbo on a normal to slick track this works well. If you need more than that you will have to setup the "anti-lag" mapping. On a high grip track I need around 13 psi or it requires too much slipping of the clutch.

Good luck!

Me and rutzky are still having probablems getting the wagon to launch...(bog city every time)

little back ground...the car is a 20g 207 with hydra externally gated
RA gears with front LSD, exedy stage 1 clutch

when launching the car acts like it wants to go then bogs...almost acts like the motor is unloading because in the middle of the bog the waste-gate releases, but the RPM's dont rise like a slipping clutch...
the launch control rpm is set around 5300 rpm at around 5psi...

any help would be greatly appreciated....Im sure BOB-E will chime in soon.....

With a 207, maybe you need to set the launch control higher?? I set my launch control (UTEC though) at 5000 on my 20g 205 and it builds about 7-10 psi. I think setting it closer to 6000-6500 would be better for that high revving jdm motor.

I'm gonna try a stronger clutch and see if that helps. I was getting wheel spin last week, but this week nothing. LC is set at 5500 in the Hydra, but my tach shows it hitting 6k

how exactly do you set up the launch control? i've been going nuts, idk if i need an external switch, or if the hydra picks up the signal somehow. how does everyone have their LC setup? i found the spark/fuel settings, but i dont nkow how to activate it.

please explain.

Line up outside of the "grove" if you are getting too much traction. I do this on really high grip tracts as it allows a little wheelspin which is better than "bogging."

Thanks,
Phil

Alan,

You need our Accessory wiring harness which is $59 to utilize the features we are referring to. Give us a call if you would like one.

Thanks,

It will not cause knock and it will usually not report false knock either as it uses a soft rev limiter. Hitting the hard rev limiter can report false knock.

Moot point now. Have you seen my hot laps video in the Motorsports section Phil? Ouch. Still trying to figure out what happened.

Oh man, fire out of the hood scoop is never good I'm sorry to see that. It's really hard to tell from the video but it looks like you had boost (watching the lights on your E-Boost2) up until you pulled off so it doesn't appear from the outside looking in that your turbocharger blew. It's likely you melted an oil line or one of your engine breather lines came loose. This can be really dangerous when racing as so much oil slouches up into the lines during sustained high g turns from the head breathers.

We run very expensive but worthwile hoses on our car and clamp everything as we've had similar problems. Luckily we've never had an engine fire!

Thanks,
Phil

/massive threadjack, but I think the question has been answered

Yeah, turbo is ok. No oil inside and no shaft play. Oil feed and return lines were intact. Stumped as to where it's coming from. My quest for answers is starting here
