Have a word with Mark Adams at tornado systems ltd. Cost me 430 pounds three years ago and it makes an enormous difference to the car .my 4.6 was almost undrivable before i fitted the new chip

Interesting info. I own a-98 4.6.
My car has the Tornado chip, and has also had the ignition system changed.

According to this source, the Morgan 4.6 is not the same as the Land Rover 4.6.

For the Hot wire, I don't know.

For the Gems the 10AS will need resetting so unless you have access to good quality diagnostic kit such as the Rovacom, then no.

Edit Just spotted this but no details as to what you get over the base chip set.

B3MOG/David, that is one well polished and attractive engine bay. I had ever thought the flapper assembly spoiled things a tad. Though todat if you lift the bonnet/engine lid of an interesting machine all you see is acres of moulded plastic..!!!

Andy G I have never had dealings with RPI though their web site used to be interesting, I have no reason to doubt your thinking on anything Morgan including business ethics.. Thanks.

Luddite, my car started as a flapper inj. but because of the problem with sourcing parts and tuning I decided to bin the whole lot including the ignition (distributor etc) it now has a fully mapped fuel and ignition ( Coil pack/trigger wheel) system and runs and ticks over perfectly plus it passes the emission test easily.

David, the first time I came across a hot wire system like yours was on a TVR that I was helping a pal to get it up and running again, I was pleasantly surprised by the miniscule size of the hot wire sensor and that it was housed in a very polishable alloy tube. TVR`s kit to fuel the Rover V8 seemed to work very well indeed, much less fussy than the flapper system too. No fear of the flapper being destroyed by a backfire either. thumbs

The hotwire ECU is the 14CUX. The mapping & program is contained in a PROM, such as a 27256, with 262,144 bits. very small by todays standards.. Some 14CUX ECU have the PROMs soldered onto the circuit board, some are plugged into a socket. If your ECU has the socket, then the original PROM can be removed (unplugged) and the Tornado chip can be plugged in as a replacement. I would think that most of the later ECU have the socket arrangement.

I don't have a Tornado chip, but have the Optimax chip, which originates from the same source as the Tornado. The arrangement is a circuit board with a PROM and decoder chip on it, this assembly plugs into the 14CUX ECU replacing the original PROM. I believe the contents of the Tornado and Optimax PROMs are encoded in order to prevent copies being simply made and used.

If your ECU has a soldered PROM it is possible to remove it and replace it with a socket, however it is a fiddly job with some risk. I have replaced a few, but it is not for the faint hearted.

While the PROM contains 262,144 bits, the program and data fits into one half of this store, and the other half is filled with a copy. More information can be found on Piston Heads via various historic threads by TVR folk

So the answer is 'yes' it can be a DIY job, with the caveat regarding the way the original PROM is affixed to the PCB

For the 14CUX if you have the socket for the PROMS in then yes it is a DIY job to fit the Tornado Chip, if you don't have the socket then no. RPi Engineering will fit the socket if you need to have it converted.

Wow techy stuff. wink

That’s for the info. It’s a 2000 registered car. I will check what I have.

Thx
