also interested, hows it going

[MrSimba]

Yep I'm in for this also

[dumfunk]

thats 3............. looks like the buy could be alive again??

[dumfunk]

ok, make that 4

ABS and TC are connected because they use the same passive wheelspeed sensors!
"spikes in the TC system" do come from the long high impedance antennas. and this is what 3m long lines coming from the ABS wheel sensors to the TC unit really are. if you do a bad electrical setup in terms of grounding points etc. you will receive all kinds of noises on the cable connections between ABS and TC coming from injection and ignition.

implementing a TC in an Elise-type car is not an easy task! you cannot just drop the system in doing the electrical connections without a care of electromagnetical compatibilty. if you get noises on the wheelspeed lines you get randmo ignition cuts a low speed even if there is no loss of grip. the ABS sees these spikes too of course and may come to the point where the implausibility is large enough to drop an error code.

I found two things that may help:
1) routing all electrical connections the right way
2) use a signal filter between ABS and TC (which is not available from RL, I developed it by myself earlier this year)
taking these measures my TC works from 10km/h up and the ABS works perfectly any time, never dropping an error code.

HID ballast units emit a lot of RF interferance. Only fix is to have A/D converters on the hub

The pump reset prior to install is not entirely reliable. You may have to get this done on the car it will be fitted to. Works most of the time but its a risk.

I've been keeping an eye out for second hand ones so if these are preprogrammed I'd be interested too.

See the above post. It doesn't always work. The be reliable you may need to reset it on your car.

is the vxr unit the same as the lotus unit? dont they come with 16+17" wheels as standard??

yes, and yes.

Don't have any. But having noise issues. Like Racelogic told me, you will probably have these issues on every Elise-type car. With standard hardware.
I am developing OEM control units for major car and truck brands for seven years now having a basic understanding of electromagnetical interference in cars. Tricky topic. Very tricky.

Five.

[dumfunk]

ok, so the count is now 5.... have just mailed hanger 111 to ask them if they can do the re-coding or whatever it is needed, and if they can supply the units at a group buy price...based on the current 5 who have shown an interest. hopefully they will get back to me soon...

[Graeme Lambert]

Add another to the list - so that makes 6 at least? G

[Bargi]

Interested, dependent on final price

[chetwin]

ditto to Bargi's comment.

[badgerade]

Interested - depending on price etc

[LMP1]

Interested - depending on price, as above

[dumfunk]

So that's possibly 10 !! I may have a 2nd hand exige one coming,so 9 maybe ,depending on price. Not expecting hanger 111 to reply until well into new yr,so a bit of patience all round. If anyone has any ideas of any other sources please feel free to make enquiries.

[Graeme Lambert]

No real rush from me. Look forward to the update in the new year though. G
