Chipped and loving it

[Bugman]

Hello all,

Just a follow up from an earlier post where I was inquiring about an after market chip for the TD5 Defender.

I eventually had mine done by MR Automotive in Redcliffe.

I've been driving around for two weeks now including towing a small boat up to Gladstone and towing my large boat around Brisbane and the sunshine coast.

In short I'm happy. There's definitely a heap more power now. Warren's trick of 4th gear at 70km and putting your foot on it is good to show passengers in the car. Down low before the turbo kicks in - I haven't notice that much of difference. I guess I see that the most when I'm launching the 3 tonne boat of the mark.

Fuel econommy is about the same just driving the car but I have noticed and improvement when I'm towing the big boat because I'm not having to drive "flat out" to keep it on 100km any more.

The guys were very good and I got them to run through the 100k service at the same time. They did pick up some work that needs to be done soon (leaking slave cylinder, worn axle hubs etc) so I guess I'll be back over the next year or two.

One thing in particular I have been having a problem with is the TC and ABS sensor. Warren cleared the error but got a report of "weak connection". He thinks there's something astray in the wiring somewhere which we have to find.

I'd encourage others to get the chip done.

Now all you need to do is take off the clutch switch for a really good drive.
Just try it, you will love it! style_emoticons/<#EMO_DIR#>/biggrin.gif style_emoticons/<#EMO_DIR#>/biggrin.gif style_emoticons/<#EMO_DIR#>/biggrin.gif style_emoticons/<#EMO_DIR#>/biggrin.gif style_emoticons/<#EMO_DIR#>/biggrin.gif style_emoticons/<#EMO_DIR#>/biggrin.gif style_emoticons/<#EMO_DIR#>/biggrin.gif

Warren and the boys are good guys always happy to help and have a chat. I've been over there a few times this week to get bitts, for a gearbox rebuild and new clutch on the Disco. They were spot on with what I needed, only thing I didn't use was the cross seals for the engine rear main.

Why would you take off the clutch switch ??

you just gotta try it to see the difference....
its the connector on the clutch master cylinder.....




(it almost feels like the car has been chipped just by unplugging this.......)</span>

The td5 engine ECM needs the clutch switch signal for fueling. With the clutch pressed, the ECM goes to a different mapping. Without clutch signal the revs don't drop when you change gears which I reckon makes it harder to drive the car because the gear change on a Defender is quite slow anyway and without the revs dropping it makes it even slower.
So a bit of an advise from a Land Rover master tech gents, leave the switch as it is.

I have had it disconnected for a long time and the gear changes improve. I reconnected it again for a bit of fun, drove around our block, and disconnected it pronto. It causes a noticeable stagger after the change, particuarly up the range. No way am I ever going to reconnect it.

If it hold revs on it, it will improve down shifts but make up shifts worse.

[disconut]

The revs actually drop but not as severely as they did previously. The thing literally dropped to idle in about 0.2 sec. Now they drop but gently. Before I disconnected it the turbo just died on the change.

I disconnected mine and didn't really notice any difference.

Perhaps I should connect it again just to see...

<span style="color:blue">i disconnected mine ages ago and i dont need to double shuffle to get the gears in.....

i can quick shift like every other car ive had/driven....
it now crunches if i take too long to change the gears.....


what the switch does do is prevent surging while just cruising at slow speed with very light throttle......</span>

[rusty]

is' nt the same result achieved with throttle control on gear changes rather than disconnecting a sensor ? is this only for the td5 engine or the tdi as well ?

[disconut]

Not on a TD5. The clutch switch just kills the engine and makes it stagger, then it also takes the turbo a while to spool up again.
Nothing you can do.
Except disconnect it!!
