TD5 ECU Upgrade

[Robbo]

I am thinking about having the ECU on my 2002 Discovery ES TD5 Rechipped by AMV. Has anyone had this done before or even more importantly has anyone had it done by AMV in Ringwood.
I am only looking at the basic mod which should increase power to around the 125KW and the Torque to about 400Nm.
I would be interested to hear the good and the bad of this mod.
:wink:

there is no bad in that mod style_emoticons/<#EMO_DIR#>/laugh.gif style_emoticons/<#EMO_DIR#>/laugh.gif

AMV done mine 5yrs ago


just love the increase in power makes the car a hole lot better to drive style_emoticons/<#EMO_DIR#>/laugh.gif style_emoticons/<#EMO_DIR#>/laugh.gif


try roverland as well for price, just tell him i sent you :wink: :wink:

you will find his details in recommended suppliers

cheers hiline (ray)

Try Bruce Davis as well. Had mine in my S2 TD5 for a few months now and its a big difference.

cost is about $1800

I got a quote a while ago from Discovery Automotive in Perth and they were asking $1700 for the kit $1950 fitted for a new chip and a larger intercooler. I have seen quotes as high as $4000 which seems a little high to me considering the aftermarket intercooler can be bought out of the UK, Allisport and landed in OZ for about $800. The chip should not be that dear as it is only a chip and for most high performace vehilces is only about $5-700.

<span style="color:blue">its not even a chip....they just remap your own ecu from what i hear...</span>

[CraigE]

From what I understand the earlier model TD5s require the chip to be changed as they are not re mappable with the later models being able to be re mapped. No offence to the guys offering the upgrade but $4000 is fairly rude. Like I said the intercooler is fairly easy to get or get custom made. The harder part is the chip, will have to try and track a supplier. The other option is to install a Wolf ECU which would still work out cheaper and is fully programmable.

Just a word of caution. I read recently a story in one of the UK mags where they interviewed one of the TD5 development engineers who said that one of the problems with TD5 ( in the context of why not TD5 for D3 and new Defender) was, apart from emissions, that it had durability problems at over 138-or 148 HORSEPOWER not kilowatts.

I guess their requirements for durability may be much more stringent than what you will accept, but that was from the horse's mouth.
You can easily turn up the wick but you could be burning the candle from both ends .
How many people drive with one eye on an EGT gauge all of the time???

Not sure thatis correct Craig as mine is a '99 S2 TD5 and it was a simple case of changing the ECU for a remapped one. Process takes about 3 minutes to do and there is a significant difference in power plus much beter when using cruise control.
Also I did a bit of research - or asked around a bit - into durability of drive line etc once fitted and by all accounts it seems the existing set up can take the extra power.
To date no dramas with mine and would receomend the upgrade. Would love to go the full intercooler upgarade as well though!!

thats my plans in the next 6months or so i hope style_emoticons/<#EMO_DIR#>/laugh.gif style_emoticons/<#EMO_DIR#>/laugh.gif style_emoticons/<#EMO_DIR#>/laugh.gif

The TD5 has basically the same basic drivetrain as the V8s at around 135kw so from a power perspective a worked over TD5 is not going to have a problem for normal driving. At the grunty end in low range where torque is the issue I am not so sure - v8 is around 320nm at 2600 RPM and a chipped TD5 is around 360 nm at 1950 RPM so the TD5 will have a fair bit more at lower revs but whether it is enough to cause an issue - I wouldn't have thought so - especilally not if standard size tyres are in use.

<span style="color:blue">and here is my question......


what will it do to the longevity of the motor......
will all the extra power cause the engine to wear out faster than it normally would....?</span>

i really dont care what happens to it 8O 8O 8O


just as long as it go's fast :wink: :wink:

[landy_man]

another thing to consider is the gearbox if manual...
I am pretty sure (heard around the traps) that the R380 designation is due to the max torque handling capabilty of the 'box being 380 Nm...
Not 100% sure if this is true or not... but if true, is something to consider :wink:

[hiline]

mine is a 2000 130TD5 manual style_emoticons/<#EMO_DIR#>/laugh.gif style_emoticons/<#EMO_DIR#>/laugh.gif style_emoticons/<#EMO_DIR#>/laugh.gif

had a new clutch fitted 37,000k's factory recall

something to do with a rubber backing i think 8O 8O


but never had a problem since style_emoticons/<#EMO_DIR#>/laugh.gif style_emoticons/<#EMO_DIR#>/laugh.gif

had my chip fitted within 2 weeks of getting the car new
i also run 35's on most 4wd outings and thrash it like you wouldn't believe style_emoticons/<#EMO_DIR#>/biggrin.gif style_emoticons/<#EMO_DIR#>/biggrin.gif style_emoticons/<#EMO_DIR#>/biggrin.gif

the biggest problem i have with the chip

i tend to pull the front uni apart every 3-4 months :evil: :evil:

The R380 is rated for 380Nm. Also the ZF 4HP22 which is behind the 4.0 V8 and TD5 is rated to 380Nm. The ZF 4HP24 behind the 4.6 V8 is rated to 500Nm.
