Agree.
But aftermarket ECUs with tuning are available, at ££££££
Who knows until you check? if it was a well looked after car it could be fine.

you can measure compression and valve lift, but even that doesnt tell you the state of the surface of the cams, or if the lifters are turning properly.
if its been looked after then its probably been fed 10W40 fully synth.. which isnt good for flat tappets, generally doesnt have the required high pressure film strength which is why we see them wearing out

It's not an EEPROM I suspect, it's actually a one time programmable ROM so cannot be altered.

Sorry the tornado chip is EPROM, but that doesn't say what the original chip is

Tornado is the one you want for the doozle. I’d guess they would ‘tune’ it by swapping to a standalone system.
The website is tuners garage, if anyone wants to dive into this a little deeper.You sound like you are jumping in before knowing TBH.
Cam lift can be easliy checked with the right equip and just removing the rocker covers.
If its worn then fine change it. Its a lot of work.
As for tuning the ECU as far as I am aware thats not possible without changing the chips and even then its a set map, or an aftermarket ECU. So would be interested to know if anybody could actually "hack" into the ECU and change settings, gearbox tuning?
I would suggest you have a talk with these people who say they can, and find out how they will empty your wallet.

in terms of checking cam lift , how is that done ? I have heard of using some metal in between the cam lifters,
So please post a link, as I can only find a Turners Garage that claim to be able to do it https://www.turners-garage.com/index.php/range-rover/wolds-leading-p38-specialists
As for cam lift, a dial gauge with clamp base would work, mag base would be difficult on a mostly Ali engine.

I was referring to the original chip.

Don't think a home amateur mechanic is going to easily or reliably measure cam wear tbh. And it won't tell you the state of the lifters.
And even if in perfect condition, an aftermarket cam is going to offer more performance......
I think you can.
Lifters are a different issue.
I never said a different cam would be good or bad, did I?

Turners. Don't think they're as well thought of as they used to be. V8 Developments might be worth a look.
Changing the cam is the first job. Easy enough to do if you follow RAVE. After that you can get someone to play with the ECU but think about what characteristics you want in both high and low range and how much fuel you want to burn.

You could put Megasquirt or similar on it and then map whatever you want but it is an awful lot of messing about for a brick of a car.
As you said, there are a few off the shelf cams available that would do the job.

The problem is the hardening is less than paper thin and once that goes the rest of the cam goes in 100s of miles
