I don't think they would work or have any affect on the issue. They simply read wheel speeds from the ABS system and cut injector pulses reducing engine power to maintain a certain percentage of slip on accelleration. Don't think it would have any effect on braking at all since you're not on the gas. Plus it wouldn't override the ABS computer either.

why not just unplug the sensor behind the shift knob and go old school with no ABS?

Won't you need to unplug the OEM ABS or is it a piggy back to use the Racelogic? Either way with the Racelogic your able to tune the system via controller. Of course if this is a cure all for the issue, it's pretty spendy at $2288.00.

Since the 370Z has electronic brake distribution and not mechanical, when you unplug it, it defaults to 50/50 brake bias which is way too much rear brake. You can offset it a little with pad compound, but still too much brake pressure going to the rears. You'll have to baby the brakes to avoid locking up the rears and spinning, so you might as well be babying the brakes to avoid ice mode. Either way, you can't use very much brake.

From what I understand, the Racelogic doesn't effect braking or the way ABS works at all. It simply gets information from the ABS system about wheel speed. The only thing it actually controls is fuel injector pulse which has zero effect on braking or the ABS system. Besides, for $2,200 you might as well run all new brake lines and an aftermarket dual master setup with brake bias adjustment bypassing the ABS all together. That's a for sure fix.

thats good to know. I was unaware of the 50/50 split. But I have never encountered ice mode with mine fortunately.

That's the first I've heard of that.

I have my Yaw sensor unplugged for a month now with no issues. Course I have had no issue with so called ice mode either. Lucky me. This issue seems more and more to me as a production issue between cars. I unplugged mine for when you do turn off the VDC control the car still has control for another 10%. Which would pop up from time to time. I disliked this a lot. Plus the yaw sensor has been proven by SOHO racing to retard timing up to 3 degrees. That's alot on the track, up to 20+ whp. For me when I get on it in the exit of a turn the power feels more planted equally (cause the traction control is retarding timing and appling brkes to a particular cornor to help balance the car, mostly for people who can't drive) and of course I have a great LSD but it all seems to be working for myself. The yaw sensor only aids with the ECU and ABS system to help modulate slip angle when slip is noticed but the ABS still works as it would.

I remember locking up rears constantly when I disabled ABS... 50/50 setting makes perfect sense in retrospect

hey, gl this weekend chris

Did you disable the ABS fuse or the yaw sensor?

Thanks man. I'll be taking the first session slow. I have nade a lot of changes on my car.

Im in the process of deleting the ABS and just install a proportioning valve + Bias Fr/Rr gauge panel then go from there . that fix will be good enough untill I can redo the whole brake setup next winter ! ;)

I thought that 50/50 was well know among us (track junky peoples...) hehe seem like the word still have to get heard a bit more.

other than brake fade with the original calipers, I've had no other issues, so I haven't studied the brake system that much.

I had no issues the first year I tracked my car either. I think what Downshift said in another thread about the pump wearing down every time you hit ABS making it easier and easier to hit it again each time makes a lot of sense in my particular situation. For those who haven't had any issues yet, I would suggest going with Shamu's approach to adding a vacuum canister which seems to help prevent it but will not eliminate it. It seems once you start hitting it, it rapidly gets worse and worse.

I've thought about doing that. It's a cheap easy project.

I don't see any reason not to do it. I have even thought myself about replacing my pump and doing a vacuum canister just so I can hopefully go back to not having the issue for a while. That or sell my Z and get something else that doesn't have this issue at all haha. Plus if it didn't work and I still had the issue I would be super pissed.

Does anyone know what they are doing on the Nismo RC for traction control/ABS, and yaw sensor?

Nothing from what I can tell or have heard. Doran's RC is not running a OEM style ABS system anymore. So you really cannot reference that car.
