Re chipping experiment
Discussion
Does anyone have a standard TVR chip for the 3.9 non cat engine going spare (Like if you have had a Tornado upgrade)? I would like to try one in my Ginetta with the same engine, and in exchange I have a modified fuel map I had done on a one off that provides a lot more fuel as the revs rise if you want to try one of these (for non cat cars only). This is just a matter of interest and I have full time fuel / air monitoring so I can see the differences between the maps.
There are at least 3 maps per chip you can select, but I notice that the TVR chip is physically marked for Cat use, and understandably TVR power would not desclose if a modified non cat map was also included in the TVR rework of the chip, as they wanted to sell me a chip. I guess Ill have to borrow a cat chip and see what it does with my tune resistor.

I think TVR Power do all sorts of chips. I'm running a 4.3 non-cat - clearly so-marked. All Chimaeras are catted as standard, but I think early V8S used a non-cat 4.0. Maybe see if they can do a chip for one of those? I don't think any hotwire TVR engines come as a 3.9. Without wishing to sound patronising, the reason they're so expensive is because they comprise intellectual property. If you copy a chip you breach the property owner's rights.
I totally understand, but do you think they pay Rover for using their basic mapping and then modify it? I doubt it somehow. Any software licence does not allow you to reverse engineer the application anyway which would prohibit modifying the origional map. I payed a lot of money to get a one off for my car, so far as im concerned I have payed for those rights, and can now do what I want with my program. ie. duplicate it if I wish. My chip is pretty good, apart from a slightly rich point at 2500 rpm, but I just want something to compare it with.

I don't know the smallprint under which you bought your chip but, typically, you will be able to use it in a single application and duplicate it for archive purposes. And I suspect you are right in that you can do whatever you wish with the bitmap. Except use it in conjunction with the 14CUX software, or permit others to use it in such a way. As I said, I don't know the terms of your purchase, but I doubt you'll be able to sell or give away a copy of the bitmap for the use of others, without consideration to the author.
Fortuately there was no small print whatsoever (about mapping) apart for the invoice for the work. Maybe the cost of paying a huge lience fee to Land Rover for the privelege of selling their software with a few minor tweeks is why some tuners are now asking over £400 for their remaps with a £10 chip........What do you think?

There won't have been a huge licence fee paid, Mark, for a 'basic' bitmap, but the bitmap specification will have been bought, perhaps on a per-ECU basis. Now, I'm out of the same industry as you, so you'll know that the price of a tuner's chip is not for the hardware itself, that you or I could copy for a tenner, but for the endless hours of research and development, using many different cars with different engines on rolling roads and actual highways: testing and subtly modifying every part of the bitmap to make the Lucas EFi ECU sing. Plus the cost of the Lucas specification itself. If I was in the market, I wouldn't begrudge paying £400 to a tuner for that kind of knowledge.
