1. How does it work? I'm thinking wheel speed to vehicle speed comparison = ignition cut.
2. How well does it work? On a street car with high power and street tires
3. Do people use it at the track in sanctioned events? How could anyone possibly check to see who's using? I assume it isn't legal.

Just wondering what you guys thought about this feature. I am looking buying something soon and I saw this was advertised as new feature.

 

im gonna say its not really needed for a street car, but than again what do I know. AS far as at sanctioned events its illegal in I think all classes except pro fwd and rwd. They would be able to tell as you have a sensor off either one of the back wheels.-pdang

 

Ahh yes that makes sense. I guess if you really wanted to you could attach a remote sensor transponding from inside the wheel. I've seen very small transponders that read tire pressure on Champ cars and such. I guess I wouldn't be too far fetched to assume people will try to get away with whatever they can.

Would this help a 400-500 hp car with street tires get down the track more quickly assuming you just ran the car for fun. Driving around the streets with a 400-500whp front driver would be difficult to modulate tire spin. An ECU should modulate much more quickly than even the best driver.

From a technical standpoint could you use this to make your car easier to handle and outright faster on the variety of road surfaces out there. I'm not talking street racing here but I like to get out on an empty country road and play around once in a while. Does anyone have any real world experience with E.T gains using this in practice or something?

 

You do not need to have a wheel speed sensor for it to work. If you exceed the maximum rate of acceleration your car is capable of, it starts retarding timing.

The AEM traction control feature is a very hard function to perfect. It compares an ideal run (that you must log) to the run you are doing. Once the EMS "sees" that your tires are slipping it will cut ignition and/or fuel to hook the tires back up. Most know that traction control is ilegal in events. No sensors are needed to make this work on the AEM. Officials will know that you are running traction control the instant your car starts to spin the tires. The ignition will be cut and the car will start to pop and spit flames. This is just the product of having cut ignition and sending the unburnt fuel into the exhaust pipes. Great function though.

 

No thats just the rev limiter hahahaha... Traction Control isn't on....

 

Assuming you could keep everything as consistent as possible i.e. tire pressure, ambient, driver -all big assumptions I know but I was thinking couldn't you feed that output signal to the throttle cable instead of an ignition coil? What I mean is have a super quick servo motor that could moudulate the throttle. I guess you would have a drive by wire system a la F1. The gas pedal would be disconnected from the throttle body with travel sensor on the pedal and a servo on the actual cable. This way you could have the pedal to the floor and the system would still be able to modulate away. They now have super quiet and powerful servo motors that could be hidden up under the dash near the firewall and hooked up to a battery so tech could check that there is a connection if they wanted to. I have never been through a real pro tech inspection though so I don't know how far they push it. Maybe the best way to do it is just practice on driving skills

By the way I think cheating is wrong but its a cool subject to ponder.

Don't some VW's come from the factory with a system like this where the pedal is not actually connected to the throttle mechanically? Hmmm

 

Its not cheating until you get caught hahaha. Just playing.

 

Perfect excuse.

 

the best winners are the cheaters that don't get caught

 

Nissans 350z/ Infinety G35 and the Acura TSX use a drive by wire system. You could use a drive by wire system for traction control but you want things to be instant. Its a lot faster to pull timing than rather wait for the air from the throttle plate to reach the port of the head. But the cool thing you can do is that you can create your own torque graph and find out at what torque the tires spin in any given gear.

There is more than one way to skin a cat.
