Racelogic traction?

[preston]

I don't have any experience with it (yet) but I've researched and kept an eye out on the forums for anyone that has used it. Pretty universal feedback is that it works and works well, but isn't exactly turn key - it does take some tuning, and as car parameters change you may need to revisit it. Also, I know of one guy who had a box crap out and cause him all sorts of issues until he figured out it was the racelogic box - which isn't an indictment as anything can fail and the more blocks you put in your chain the harder it is to troubleshoot. But generally the reputation of these things is good and I look forward to putting one on my car someday. Adding the wheel sensors and the cost is the biggest hurdle.

Of course a modern powertrain engineer will tell you that Throttle by wire with the computer TC controlling the throttle rather than trying to cut spark and fuel is a far superior way to go. Also the racelogic stuff only takes wheel spin into account I believe, whereas a more sophisticated system can use many inputs including ground speed, engine variabels, and any other signals present in the ECU.



Given that RaceLogic costs $2k or whatever (I think that was with their wheel sensors, its cheaper without it) if you are looknig at buying a new ECU it may pencil out to buy the Motec800 - This box costs $4500, but includes 3 dimensional traction control and drive by wire ability (as well as all of the other capabilities of a high end ECU). You can buy the LS2 pedal and throttle body for less than $1k I've heard. So this is another path to much more sophisticated TC. The motec could also do spark/fuel interrupt as well, if you don't want a wire throttle.
