The original chip is soldered in.
If you are contemplating a chip change you can however unsolder the chip and solder in an eprom holder. This allows you to fit a new chip dead easily. Needs to be 28 pin. Get the holder that has the small lever at the side (try RS Components). It also allows you to copy the chip.

Bill, be very careful who you use to re-chip. These are old ECU's and many fail after they have been disturbed. You need at least 6 months warranty on the whole ECU after it has been chipped to be safe

I had a PSI Powerbox and sold it on. I had decided when I bought the car I would have it re-chipped but could not afford the time off the road while they sent the ecu away. Powerbox for the P38 is £330 so quite a lot more than £90 for the L322! Dont honestly know which way to go really. The car is running pretty well since I cleaned out the Intercooler and intake manifold so might just leave it alone. It was just that I saw an advert for a self fit chip and wondered if it would be difficult to do it. I have temp controlled solder station and a 'scope etc but not sure I want to tackle an ECU. I remember too well sorting out dry joints in the ECU on my old 1986 Classic RR.

Yes, thanks for the good advise Keith, I must admit that although I had been looking at the idea of using a professional outfit I hadn't considered the written warranty.
I had looked at buying a secondhand ECU and sending that off but there don't seem to be any available at a reasonable price for the later diesels.

You don't need to pay stupid money for these boxes
There's loads of different makes on eBay
There's ones for the l322 for £450 !!!
They all do the same job
I bought a cheap one - has 16 different power settings that can be changed to suit your power requirements
It works great - gearbox changes gears now without holding the gears too much
Why spend £300 when £90 box does the same ? Your paying for the name lol

They all do the same thing in principle, it's just that some do it well and some do it badly. Some have a well known name to protect and some don't give a ****
Zif socket was the word I was looking for Bill.
Unsoldering the chip on the ECU circuit board is not a job for the faint hearted. I did it when I fitted a secondhand superchip but I destroyed the original L/R chip in the process.
Better to get it done professionally by someone who has all the gear.
As a separate issue how about starting a library of fuel maps to download? Non copyright of course.

Afraid I don't know anything about fuel maps at all. I have used ZIF sockets when I built a few computers in the early days but now it is all laptops.......beyond me. My real connection with electronics is amateur radio, which is why I have the gear. When I did the dry joints on my classic rangie all I had was a cheap Maplins soldering iron - that was scarey!!!
Still, it might be interesting to see a fuel maps library, but I am not your man.
