Is that what dut dut dut is? Moving forward but with half-traction? Like most people living their life with half-ass intention?
Hahah yeah Its the tyres getting traction, suspension binding up tight, then traction gets lost, suspension decompresses, then it repeats itself. Unless you mean dut dut dut is the rev limiter because it has lost traction and revved hard :|
I assume you mean axle tramp? I've tried pineapples, different tyres, different tyre pressures and all to no avail. I think the only solution is to hard mount the rear subframe to the chassis.
that's what I intend on doing >> I've got solid alloy engine mounts, solid alloy tranny mount, solid diff bushes and I've yet to machine up the solid subframe bushes that allow you to adjust the rear subframe angle easily. That should get me almost a solid mounted setup.
I've always had axle tramping from day one so I replaced the shocks, springs and all the bushings to urethane ones. I went to the drags and I got axle tramping so bad that it chewed up and spat out a diff bushing and that's what started me down the road of solid bushings everywhere or rose jointed. I haven't had a chance to try out the solid engine mounts and gearbox mount. I've got some pineapples I would like to try with this setup and using urethane subframe bushings but if that fails then I'll be trying some solid subframe bushings. If that fails then it'll be time to make some rear lower control arms to change the amount of anti-squat that zed has in it.
rev limiter?? What? Mine doesn't bounce off the limiter, it just holds it steady at 7000, is that abnormal??
It should rev to 7200 (stock ecu cutout)... ...the tacho doesn't normally move, but you can hear it when its bouncing off the limiter, it sounds like its missing.
Interesting... ...when tapping into my ecu (on the stock map) it was set as 7200rpm. I've seen other zeds with 7200rpm cutout aswell. *shrug*
I know I've posted this before.... but... The Zed has a multistage rev limiter, not a hard cut. It cuts one or several cylinders by disabling injectors. Taking 7200rpm as the rev limit.... rpm < 7050: normal operation 7050 < rpm < 7100: cylinders 1 and 3 are cut 7100 < rpm < 7125: cylinders 1, 3 and 5 are cut 7125 < rpm < 7175: cylinders 1, 2, 3, 4, 6 are cut 7200 < rpm: all cylinders are cut I am not 100% positive of the actual cylinder numbers, but you get the idea. If the stock limit was 7200, you can see that at 7050 it would start to cut, and possibly give the idea that the limit was only 7000rpm.
I just scanned through all of my stock ROM ranging from Jap to Euro, 90-94, NA to TT, and they all have the rev limiter set at 7000. Not that I doubted you at all Ben
strange, mine doesn't bounce at all, as I said, just holds steady at 7000. anyone want to redline there car for me and tell me what happens, maybe mine's a freak.
Umm, no offence Sam but it's disturbing that you can hold it at 7000rpm long enough to see whether it's bouncing or not ... Peak power/torque are made much earlier on most motors so just wringing it out is probably slowing you down if you are squeezing every last hp... I bet Nissan built in a sizable safety buffer before things disintegrate but why test the limiter on a 13 yo motor?
nah not like that, not my fault I was driving it just after I fitted my adjustable tension rods, and my dad was in the car, i went to change into 2nd, and it just revved out like all hell. I clutched it, not knowing what the hell was going on. Turned it straight off cause I didn't know what to do. Then thought maybe the throttles are stuck open somewhat, started it up, straight up in revs again, blipped throttle and down she came. Believe me I'm in no rush to kill my motor.
never happened again - i presume the throttle stuck open but yeh, no idea why. It was about 10 months ago so I think probably just a one off/ freak
