anyone undertaken this upgrade
Discussion
Ive just came off the phone to 'Mark Adams' who makes the tornado ecu chip the other day, received mine in the post yesterday. He explained what it does, why its better etc & i was totally sold by it.. Will fit it when the bodys back on the car etc in January, will let you know how it performs.

Worth doing ! Chip it then map it !
The 14cux works well just parts that are "Lucas" are cheap copies even if brought from a good supplier ! I had a fault on my car rough running, I spent a lot of money looking for it Top Cats found the fault a Lucas Rotor arm and Cap.
I later changed to emerald, I would like to say it runs better but it doesn't its the same !
Worth the money to change ? I spent close on the same to find the fault with the 14cux....
The chip will give a bit more power but will run better if that's your only mod I'm not sure you will notice much of a difference.

Fools and there money!!. A few facts to chew on. Most cars are catalyst fitted, so the fuel mixture is clamped at 14.7:1 by the lambda probes between idle and 3400 rpm- ie where the car is most of the time. Re-chipping CANT change this basic fact. Sure you can tweak the idle RPM, cold start fuelling, RPM tables and open loop fuelling- but guess what- TVR already chipped the engine for maximum power, so any gains are really very very small if at all. Anyway "best guess" maps are just that- if you want the peak performance get the car re-mpped at a lot less than the cost of a best guess map. Ignition??? I bench tested the A&R Amp along side the lucas amp- its peak HT is lower than the Lucas, but its burn time is a bit longer- in real terms it makes b*gger all difference to the ignition system as the peak power to the spark is controlled by the coil, not the amp. Thats why people use coil-packs where you can increase the dwell time to maintain a good spark- anything else is just smoke and mirrors.

ks .Funny you should say that Daz- I think the MGR owners are waking up to the truth now, its a pity its taken so long. Problem is is you had forked out £xxx for a chip you have to think its done something amazing even if you cant prove it. Just tell your mates down the pub about this great power upgrade.....

The OP should save his money and put it towards proper engine management system where the fuelling can be easily mapped, and the ignition runs wasted spark using coil packs and can be mapped too.The difference is night & day

If your going to see jools is there any point putting a upgrade chip in at ££££ when jools
Will just over write it when he is doing his thing on the RR?
The cost of the physical Eprom chip is about £2 but you can take the TVR map, and modify it and then program a new chip. The old chip can be erased and reused, but it takes about 40 mins to do so not effective for rolling road time. The value of Jools work is the remap, not the chip itself. Mark Adams puts a scrambler board on his chips so you cant copy them directly, but there is no reason to as there are plenty of maps with better basis now FOC on Steve Sprints web site.

Id say that's true if your 14CUX and ignition is not spot on, but its still very capable even if 25 years old with a bit of TLC. After all the RV8 engine predates the 14CUX by 30 years and that's a basic efficiency issue.The difference is night & day

Jools will be sorting any upgrades i do
Merry Christmas to you all
, he will sort out any niggles you have and fit any upgrades worth having if thats the way you want to go Chimp871 said:
Was just watching their YouTube channel, cause Xmas TV is epic again, and I was intrigued by the a&r amplifier.
Take it is fools gold?
Gents,Take it is fools gold?
That is my car in the RPI video. I was having running issues at the time and I too was intrigued by the Tornado chip and the A&R Amp. I decided, rightly or wrongly, to have both fitted at the same time. My reaction was to a genuine improvement in the running of the car. It turned out, however, that I was still having issues and I removed the amp to see if there was any difference in the symptoms that I was experiencing. I found no difference without the A&R amp and the standard amp fitted.
On further investigation, I had issues with the AFM. Having replaced this, which cured the running issues I had been experiencing, I then tried the amp again. I could not perceive any difference at all running with the amp so it has again been removed and I am currently running a standard set up except for the Tornado chip.
Having also done a back to back test since replacing the AFM, the car runs smoother and is more responsive under all conditions with the Tornado chip than with the standard chip. The added bonus is that the car runs cooler as well. Don't get me wrong, it didn't overheat at the drop of a hat before but it definitely runs cooler.
So, in summary, in my opinion, the Tornado chip is worth it and the A&R amp, to me, is not.
The chip will remain but the amp is not going back on my car.
Anyone want to buy the A&R amp off me?
