Power Loss On Downshifts, Bouncing Idle And Slight Hesitation At Specific Rev Point -R34Gtt

Drive along, stomp brake. Do a skid. On gravel would be easiest.

Ok will try that out, now Im kinda getting why the ABS shouldnt work, because ABS and TCS rely on the same wheel sensors n I've broken that circuit by pulling the TCS fuse? Best be I remove that TCS butterfly and put that fuse back in

The ABS and the TCS share the same fuse. Why? Because THEY SHARE THE SAME CONTROL UNIT.

[Kinkstaah]

They literally have the same ECU as mentioned above.

I'd be checking ABS, mainly cause TC was your issue, and you didn't have (either!) TC light on. So maybe your ABS light is also mysteriously on.

Would have been interesting to see if this whole thread would have happened if the light bulbs were in the dash to begin with, hehe.

Leave the sensors and stuff connected, just remove the plate. When when you can confirm everything is working right, everything is where you need it to be, and you know what's going on with it all... then pull the light out

[XKLABA]

Just wondering, if you had different size tyres front and rear would that tell the TCS ECU that you had wheel spin

[GTSBoy]

Maybe. I don't think it's as touchy as the 4WD system though.

[rondofj]

With all this talk of ABS, when I think of it there have been numerous instances during on/startup when all the lights go on, my ABS light takes 1-2,3 seconds longer to go out than the others. TCS/SLIP/HICAS lights never been on at all.

[rondofj]

And weird that pulling fuse out doesnt trigger engine light, how would someone know if their fuse is blown n systems not working?

It would on a Nissan ECU. PFC gives no fark.

Does anyone know if its possible to just pull off the J Pipe (one that houses the stock BOV) and remove the TCS butterfly with the throttlebody still bolted on? I cant even see the bottom 2 throttlebody bolts with that ugly TCS motor in the way lol

[Ben C34]

Don't think you could. But you might as well try.

An extension and a socket gets the bottom 2 throttle body bolts very easily.

[rondofj]

Took the f$$ker off and the TCS fuse back in- easy 30min job, no need to take off throttle body, just unscrew TCS butterfly from the front after taking off that annoying J pipe. So no TCS butterfly interrupting my performance now due to faulty TCS ECU/wheel sensor? and ABS system now re-enabled with the fuse back in.

The TCS butterfly centre stem has a slot through its middle as you can see, will this impact performance?

[rondofj]

[Ben C34]

Good work.

I wouldn't worry about any performance loss, that butterfly is left in place for most people.

[rondofj]

Oh cool then, thanks champ
