Td5 Allisport chip upgrade

Hi, not long had my 2000 defender TD5 and it has an Allisport chip piggy backed onto the ECU (if thats what you call it).

The car is awful to drive at low speeds but pulls like a mad thing high up. I am looking at getting it remapped / chipped to make it more driveable off road (its too extreame as it is). Could I just unplug it as its on a D type connector without any probs?

Anyone had expereience of this?

sounds like a crap map to me.
have you contacted Allisport to see what they say? it may be that the chip fitted was designed to give maximum power, rather than an even increase accros the revs.

Thats the trouble with piggy back set ups. They do one thing or the other well but if you want a specific map then you need to go to somewhere that can tailor make you what you want. It took Gary two or three hours at Alive Tuning to come up with the final mapping and we took the vehicle out between map dumps to make sure it was what I wanted.

from what ive read, some of the earlier TD5s are unsuitable for remapping, and piggyback is all that's available without swapping the ECU

Mine is a 1998 TD5, one of the very first, and there was no need to swap the ECU. Gary did some fancy soldering and replaced the original soldered in chip with a socket and fitted a new reprogrammable chip. Job done.

I should add this is not something you could do in your shed with a domestic soldering iron or a blow torch It needs specialist equipment and years of practice.
