This is what the MBE response curve looks like. You can see how there's ~0.6V between 15% (idle) and 60%.

The digital-to-analogue converter embedded within our sensor gives a resolution of ~0.004V or 0.09°. This is significantly greater than the resolution of the MBE map

I'd be interested to see that response curve but I can't see anything on my phone or PC....

when you've gone to emerald, so you could argue you would save 600 pounds on TPS sensors towards the cost of a conversion!

Also worth noting the Emerald can be calibrated with just a couple of clicks in the standard software to work a large range of different pots should you need a new one...

I’ll be investing in a pair of these. I looked into the idea some years ago but didn’t really have the time I would need to devote to it.

Hall Effect pots are an ideal solution, rugged and accurate. The benefits justify the expense IMO, given that the TPS is the primary input for the ECU. With the programmable ones being quite pricey to start with, the R&D (thanks StunnedMonkey!), plus a small market, the price they are asking seems fair.

Has anyone managed to buy these from Motorclan yet, I can't find them on their site?

For the 4.2


For the 4.5

Looks like they are £500 now too....

Thanks!

So if you had a remap on old pots & changed to these new ones, I guess you should really have a new remap too.....

Thanks chaps, yes, the price has been corrected now. Thanks also for re-producing my graphs - that'll teach me to try and embed Facebook images....

I was wondering the same but probably the difference is comparable to what you would see between two normal pots

You mean if some one had a remap with a worn out pot then fitted a replacement regular genuine good pot (back when you could get one) it would be the same?

I guess its the same as it remapped with any faults at all really....

I mean the difference between any two random brand new pots is likely comparable to the difference between one of those and a HE version, except the latter would give a more linear and cleaner output. A remap would be ideal but (I am guessing) not strictly necessary.

A remap wouldn't be required.

You would just have considerably lower and more consistent adaptive values (pending the rest of the air path controls being OK, link rods, bearing wear etc).
