power chips

[Les Hunt]

I am considering purchasing a DP power chip for my TD5 series 2. The manufacturer is promising a 'up to' 33% power increase. The website description of the function of the chip is credible. At a price of (I believe) $1500 it is a significant investment. Has any member purchased or have knowlege of anyone who has purchased one, and their opinion of the product. I have been told that re-mapping of the stock chip can be done, but has to be done by someone who really knows what to do. The DP chip offers no alterations, just plug in & get the improvement.

Send a PM to Tombie2 and discuss your requirements with him. He has plenty of knowledge with regards to chipping.

Ok
I have one fitted but find as we get closer to ther 10,000k mark I have to unplug it because it makeds the D2 accellerate unevenly. Spoke to DP and was told that the D2 was fuel pressure critical and as the filters get dirtier I need to wind the boost back on the chip. Tried that but no real improvement in accelleration. Any other members with the same problem??

Btw when it works, it WORKS!!!!

sounds like a case of the DP rep hasnt got a clue to me!

i still dont know why people choose this option over the ECU flash type????
half the cost if its your ECU, about the same cost as the dp chip if you buy a new ECU... power figuers are less than the ECU flash and fuel economy isnt as good.
and you can now have your ECU tune emailed to you!

oh oh and there is a switchable ECU, one that can be switched from power tune to standard tune...still for less than the DP chip:eek:

cheers phil

Came with the D2 so it didn't cost me anything extra. The DP dude was the DP support line fella at the end of the 1800 number on the chip. Surprised me as well with his reply.

Les, I have an ECU upgrade "chip" from Triumph Rover Spares in SA. I haven't given it a full workout yet but without properly checking output figures via a dyno I'm happy to say it "feels" to have increased output by 25-30%. And it costs a third of the price you quoted.

People choose this option because of a slick sales pitch and/or a lack of understanding of all the options.


There are problems with using a piggy back units like these on a TD5 and other unit injector engines (VWs) – Dtronic even withdrew their TD5 product from sale after many problem that they finally admitted they just could not get right. All units already sold were offered a full refund. It has to do with the fuel pressures and the error reporting to the ECU, the piggy unit does not pass these through resulting in the ECU not delivering as well as it otherwise would and sometimes resulting in engine shut down. If you have not had a problem yet there’s a good chance you don’t know you’ve got the 2nd one yet…


This is why the LR specialists (Davis & TRS) rechip the early TD5 – the ECU is opened and the original chip removed from the circuit board replaced with a new one – not just add a plug in unit inline. better yet replace the ECU with a new model...


Tombie2 on this forum (Total Rover Tech) is selling and supporting in Aus upgraded fuel maps, it is a different file developed specifically for each model of TD5 by www.bellautoservices.co.uk (http://www.bellautoservices.co.uk) (I nearly fell over when he told me how many different TD5 variants he has now). This file is uploaded to the ECU and he's selling for stupid prices compared to what is quoted above if you have a programmable engine ECU – approx early 2002 on with ECU part number NNN***** And if the files he has in stock are not perfect in your car he gets a custom one created for you - I know mine was done on a Sunday and emailed from the UK - try that with a generic on seller...


If you have a non-flashable ECU he is selling exchange replacement units for still much less than mentioned above.


A reprogram of what’s there will always be better than adding in a signal manipulator – that’s all these piggy backs are – they just hold the injector open longer by providing voltage for longer, don’t change the timing increase the number of injections or anything clever, just poor more in.


The market for these piggy back systems came about due to the Jap vehicles still not having the ability to reprogram and the unit sold for a TD5 (or any engine) is the same, they are not even specifically designed for the target vehicle resulting in very low development costs - they should be nearly giving the stupid things away.

Oh God – I just re read this… They are right. The re-mapping has to be created by someone who really knows what they are doing and they are admitting that they don’t.


Luckily once the fuel map file is created by an expert any idiot with one of many different electronic diagnostic systems can "push" the file in. It took me about 3 minutes, just make sure you have a fully charged battery apparently there has been some interesting results with varying voltage – I hooked up a charger to be safe…


As I said just supply a generic unit with no understanding of anything but the profit margin…

Thanks to those who have given me advice on the issue of Add-on Chips versus Re-mapping. Think I will pursue the latter.

For what it is worth, I had my chip "done" by Bruce Davis in Sydney defiantly the best mod that I have ever done to a car. More power and toque across the whole rev range it has completely transformed my disco's performance. On the down side, it is using more diesel but I am unsure if it was the chip modification or the extra use of the right foot hard not to now that it goes so well

talk to tombie....

if you dont you might as well go roll triple doubles in monopoly


go to jail, go directly to jail, do not pass go, do not collect 200 dollars.

do not do an addon chip, do an ecu reflash/map.

I know this is a little late to be adding to this thread but, a friend just got a TDUK diesel power chip from the UK(off Ebay) for a Disco 2 TD5. It is apparently the same as a DPchip. It cost $545.00(Australian) delivered to the front door in Melbourne plus a 10 minute installation. No wires were needed to be soldered anywhere, as I have heard you have to do with other brands of chip.

My friend is very impressed.

No surging or any other problems as stated by some vendors in this forum.

As for Dpchip and the other well known brand, I have rang and asked them to justify their prices(around $1300) when you can buy a remapable chip for a motorbike and have it tuned on a dyno for $800. They haven't really got any good answer to justify their prices.

I would say my friend got a bit of a bargain.
I hope this helps someone reading this.
Cheers

I'll say, thats a LOT less than their website special lists at...

Without freight their discounted price comes out at over $650.00 AUD.

Glad he's happy with it.


As for bikes, slightly different kettle of fish....PowerCommander III and quick dyno tune may be $800.00, but less parameters to adjust in a EFI bike...

Hmmmm, forgot to mention that the price($545) was with an ebay make an offer discount, and with excellent support over the phone

There are still none of the problems as suggested by some vendors in this forum!

Cheers :D

Suggested by WHOM?

And what problems are you referring to?

Is it making the right amount of boost? What EGTs is it getting to under load?

How much extra 'mumbo' is he now making?

There are so many variable, this is a open ended statement.
