What can you guys tell me about this feature in MOTEC?

Thanks in advance

After watching the skunk2 9.6 video, I want to learn about MOTEC and traction control. Does it make a difference? Anyone has experience with it?

 

Is traction control even allowed in NHRA all motor? I know Hot rod doesn't allow it.

 

None of the classes allow traction control that is a fuction of the brakes. Any other way is legal.

A boost controller can be defined as a traction control device. Because you limit the boost to the point of loosing traction.

Rear wheel speed sensors are not legal in hot rod, that's assumed the only way to do traction control...

Like John said, there are many forms of "traction control". Motec can monitor driven wheel speed and non driven wheel speed and compare the two, measuring slip. With this information, you can do various things with fuel and spark to control "slip". There's also boost control, there's rev limit raised by time, etc. AEM has some sort of traction control as well, as does the MSD Programmable 7 ign. box. I think both theirs work of rate of acceleration, so no speed sensors are needed.

 

So basically, what you are saying is that even though traction control in not allowed, there are grey areas where it can be used depending on the engine management?

Can someone list top drag racers that use MOTEC?

 

I am using gear based fuel, ignition and boost to control power in 1st gear only. All other gears are Boost vs VSS.

 

Well, alot of top racers use Motec, but i wouldn't attribute cheating or traction control to that. One of the most beneficial things in a front wheel drive car is good boost control. Motec has that. Boost by gear and rpm, so pretty much infinite control of boost. If you know where you're not spinning (which you will from datalogs), then you know where you can give it more, and vise versa, allowing you to take full advantage of the track. Motec is one of the best systems available, so it should be no surprise that alot of teams that know what they're doing are using it. The winning teams are the teams that are good, they will win regardless of what system they use. They just choose to use Motec because of it's capabilities.

...Using the Motec is without a dout the best, but your also
gonna pay a **** load. you could save yourself some money,
while still getting the job done, by using hondata s300,( which has some
traction control type features) and a good boost controller such as the innovative multi stage.....but if you can swing it. motec is where its at!

 

Keep in mind, you're comparing a honda based ecu to an ecu that will work on ANYTHING. I agree, for a honda, the hondata and neptune stuff is VERY good and it can't be beat unless you're willing to spend 5-10 times the amount of an s300.

 

Yeah, the Keep It Simple Stupid (KISS) factor of the s300 or the new Neptune RTP is wicked.. I'm seriously looking at it for my race car.

 

We use a Motec M800 on the Mazda 6. We utilize the traction control function and have yielded 1.24 60' times using a traditional clutch. ProFWD is the only class that it is legal to use traction control in. We measure drive wheel speed vs. ground speed ( in our case rear wheel ) and adjust on a percentage of slip and amount of cut and or timing retard to let the rear wheel catch up to the drive wheel within a certain percent. It's not easy, but it is very efficient, as long as you don't drag the motor down too much and remove potential power! There is a fine line there, and it is a bit touchy.

There are other ways to do traction control without a "live update" of wheel speeds. This way takes a large amount of info to utilize and the engine management software must be capable of having a timing feature and or accelerometer. I know of a few teams that utilize this type of traction control for their cars, but it is 100% legal!

Hopefully Neptune RTP comes out soon.. I've contacted them a few times, but nothing solid at this point. I need to pick (Hondata or Neptune) soon, and it is for more than one car, and maybe even my street car (Which is not even a Honda).

Sorry for the thread Hi-Jack.. I think Motec is wicked and I've had discussions with my team, just not in my budget! Plus, I'm thinking KISS for the 06 season.
