Steve Heath Engineering will be launching some new products at the Griff Growl on the 9th August.
- Racelogic Traction Control kit that allows owners to install the system without professional help.
- Fan belt tensioner spanner than makes fitting fan belts easy.
- Speedo sensor replacement with a built in diagnostic LED.
Nice one Steve, look forward to seeing the kit.

Would help in setting the gap.

Rather than driving it and seeing that the speedo isn't working or running the car on axle stands in gear etc . . .

But Johno... if your speedo dies you'll be the first to post up here saying how do I sort this out?Cheers . . . More money saved
If the speedo isn't working how do you know if it is the sensor or the speedo itself? You can run the car on axle stands in gear but that won't tell you if the sensor is working. Even with a multimeter a no reading may not indicate that the sensor is duff. So you go and spend £80 but the new sensor in place and it still doesn't work. Is that to do with the gapping or is there another fault.
With the diagnostic LED you can see if the sensor is working. The sensor does not require the wheels to be turning to generate a signal. Put a tooth in front and it will sense it. The sensing distance is also mm so no getting the feeler gauge out or having to clean it.
Oh and it comes with a replacement bracket so you don't even have to struggle to remove the old one when it's corroded into the bracket.

Yes I agree it is a replacement rather than an enhancement except.... because the sensor works with any wheel speed, it is ideal for sat nav systems as it will give information even when crawling along in traffic where the original sensor doesn't do anything. The sat nav thinks that the car is stationary but it has been moving.

I'm not sure I follow this. If the car is crawling steadily along that a sat nav system isn't seen to be moving (except over a distance long enough the satellites it talks to recognises the sat nav has moved far enough therefore it re-coordinates its position) it won't read speed? You're saying the LED sensor will read speed, no matter how slow? I still don't follow the relationship you imply between the LED sensor and a sat nav? The two are not linked in any way 
Please explain.
TIA

Many sat navs have a speedo input so that they can work out by dead reckoning how far the car has moved. Used to augment the GPS signals or where coverage is lost. Not normal with the "stick it on the windscreen and get it nicked type" but very common with the built in systems. With the original sensor, the speed pulses are not generated below about 5 mph or put another way, the car is moving slowly but the sat nav effectively sees no speedo input and assumes the car is stationary. The solution is to fit another sensor that works at these slow speeds and that is what mine does.

That's the part which confused.shpub said:

Thanks for the clarification.My speedo works every once in a while. The Road Angel suffices, but I'm considering your sensor upgrade.

In addition, Steve will be showing his LS1 powered Cerbera for those interested in finding out why this engine is gaining popularity.
No surprise - this is the engine TVR should have used from the Cerbera onwards. Had they done so, they'd probably still be trading.
I wish I could have done it as well.
It was looking good but I had to change the spec of the sensor I originally thought I could use as it didn't quite do what it said it would do...... On paper, it should have been OK and on my test bed it was fine — but the reality was quite different when fitted on the car as it started to lose pulses. This was all to do with teeth spacing and frequency. It worked fine up to about 55mph but I didn't think that would be acceptable. Well, officer, what do you mean I was doing 140! My speedo only says about 50! Maybe that's a selling point....
Despite having spent many days trying to find a better spec sensor for the same cost, it wasn't possible — so I have had to use a more expensive unit which has increased the price.
However, the overall package is about the same cost as the original TVR sensor, when you consider VAT and delivery. It is so easy to set up and will cope with trigger wheel run out — which is the main reason the original unit drops out or fails regularly. Add the fact that you can test the whole system to easily diagnose any problem — which you can't do with the original — and I reckon it's pretty good value.

Fair shout,Steve,it still looks good value compared to TVR dealer prices for the std unit.I was hoping to save myself a few bob buying this,as although i should be able to get the original sensor much cheaper than dealer prices,it would have been a no brainer if yours had come out at the original intended price.I'm afraid i'm dictated by budget at the moment though
