Has anyone donw a chip?
Any companies you've bought one from???

I have experience of several JE Engineering chip 'enhancements'. 180bhp in a TD5 90 (with appropriate intercooler and plumbing upgrades) was quite something.
Not cheap, but it seems to work without overfuelling.
Costs a fortune in rear drive members.......... :shock:

Thats great, I'll give them a call and get some advice.
I'll buy some half shafts too ;)

Tried Superchips, van Aaken, Autologic. CBA to go into the detail but I settled on the Autologic! One question I would ask is, what parameters is the chip actually modifying; some chips just change the injector pulse length, which is a very simplistic way of looking at things, whilst others take a lot more control over what's going on.
I have a spreadsheet which compares the "before" and "after" curves on lots of different chips from the manufacturer's data, if anybody wants a copy I'll dig it out. One interesting thing is that the "after" curves on some chips are smaller than the "before" curves on others, which suggests to me that the dynamo operators' data is essentially worthless; also below 1,000rpm the torque curves and power curves behave in a way which breaks the laws of physics, but who am I to criticise the dynamos.
Finally, beware of a couple of chippers who give you oodles of performance at the expense of your exhaust manifolds, which are virtually guaranteed to warp and need repair/replacement quite frequently. There was one in particular which used to come up all the time on Usenet.
By the way, I'm talking Disco TD5 here, but although there are minor differences with the Defender it's essentially the same argument. My torque curve comparison has some of each.

Ah, here's my spreadsheet:

I've had a JE Engineering "Stage 2" (remapping ECU + larger intercooler) fitted to my 2004 110 - it had 27k miles on the clock when I had it done and it's now got 67k on it. So 40k's worth of hard work, towing the BWSOW etc.
Problems with this? Nothing at all. No extra wear on things, no busted UJs or CVs, gearbox still quiet and smooth.
I've had a (documented on here somewhere) problem with the injector loom which I managed to solve myself with some lateral thinking. I also had the exhaust manifold studs break - but that was before the Stage 2 was done. I solved that problem with a JE Engineering stud kit - a cunning combination of spacers and washers that allows the manifold to move a little without stressing the studs.
The remapping works beautifully. No strange or mysterious light effects on the dashboard, no need to wait for it initialise, just loads of torque throughout the rev range.
Overall, together with raising the transfer box gearing to the 1.2:1 ratios, this is the best money I've ever spent on the 110 - thoroughly worth it.
No connection with JE Engineering, just a vary satisfied customer.

Allisport gets my vote!!!
What ever you do, don't go down the bodge route of a plug in box!!!

Have you ever herd of Belautos in yourkshire???
I have a 2002 110 that has had a remap by him, I have a 2002 90 Haard top that has a JE stage 2 and I have an offroad 90 with 2004 td5 running gear and has a J Fern map. I can tell you that the JE one is a good road map but strugles when offroading on rocks or steep uphills with no space to gain momentum. The J Fern one is wild and powerful but smokes a bit too much and consumes a lot of fuel when driven hard, while the one from belautos has the best low end torque and a better economy than the standard LR map. It is excelent for towing and offroading.
