Thread: TD5-Pulled clutch master cyl ECU plug, TOPS

<div class='quotetop'>QUOTE(dhumphri &#064; May 15 2006, 01&#58;39 PM) Quoted post</div><div class='quotemain'>
Reading thru some old post the other day and found one on pulling the ECU plug at the clutch master cylinder.
Tried this on the weekend and the difference is fantastic. Gear changes are soooooo much smoother now.
If u have not tried this I recommend it

Huh?

The Td5 clutch master cylinder has a pressure switch to let the engine ECU know when the clutch is disengaged.
It reduces the engine power momentarily (or something like that) but some have found it&#39;s better when it&#39;s disconnected, like dhumphri obviously has .

Sounds good. I&#39;ll be trying it this evening. I really hate the gearchanges on our Td5 - I&#39;ve learned to do them smoothly, but anyone driving it sends shockwaves down the transmission and back every change.

Omaroo I was frankly amazed by the difference. I cant understand why u would have this sensor attached after a weekend of driving my vehicle without.

I also got rid of the centre muffler on the weekend as an experiment - had a stainless pipe made up by a local exhaust shop. This has made the engine much smoother and more responsive above 2000RPM.

My truck used to hate revving at or over 2500, now it seems so much sweeter in this RPM zone.

No matter what others say though it does make the car harder on the ears but not by much, the exhaust now makes a really low resonant sound where as before I did not notice it at all.

Also sounds good Daz

Yep - same complaints from me. Engine seems really rough and rattly over (what I think is) 2500rpm or so. Where abouts are you? It&#39;d be interesting to do a comparison on the two vehicles to see if our gripes are just normal or not.

Am in Sydney - live in Kurrajong Heights and drive down to either Richmond or Blacktown each day, then get the dreaded train into the city.

From what I have been able to tell the roughness over 2000 rpm is normal.

OK - I did this when my wife made it home with the Defender (it&#39;s her daily driver - lucky sod&#33.

This is the single best piece of motoring advice I&#39;ve received this year. What a difference. Gone is that horrible slowing between gear changes. It&#39;s so dramatic that I&#39;ll have to re-learn how to change gear smoothly in this car again. The vehicle doesn&#39;t slow to a crawl between first and second any more - it accelerates better through the gears as you don&#39;t lose momentum at all. What a ripper&#33;

SO.... what&#39;s the downside anyone? I&#39;m sure that this was all very much of the design plan for the Td5 - so what is the original purpose? It cetainly didn&#39;t help with smoothing out changes if that&#39;s what they wanted....

On manual vehicles with Cruise Control the cruise wont disengage when you hit the clutch and the vehicle will roar to redline.

Thats the issue&#33;&#33;&#33;&#33;
