Been there, still doing it...

Huh?

[Seb.F]

(I contacted, several lotus delears, steve and thorney as well.)

Ahh right I see! Makes sense. Seems TMS are one of the only people around that can get it done. Lotus said they CAN do it while fitted to an Elise/Exige but no guarantee it will work.

EVERY Lotus dealer with a Lotus Scan 3 AND the BLUE OBD CABLE for Lotus Elise '04 and up can do this with the Lotus ABS unit mounted in the VX220. He just has to try it. Been to Lotus Hamburg and they did it that way. And many 10 of VX drivers in germany did the same way. Trust me. They can.

[Seb.F]

I'll have a chat to them then!

My plan was to take my car up to Chris Neils and they can reset all the units on my car before sending them out. I'll just bung the VX unit back in mine as the abs is fine in mine!

[techieboy]

MartinS and SteveB definitely had theirs activated by a Lotus dealer with them fitted to their VX's.

Had mine reset / setup by Dick Lovett in Swindon today for £52 and its amazing, its like driving a different car in the wet

I'm sure there's no way they'd offer any form of guarantee as they don't "officially" believe the units are interchangeable.

I'd prefer to take the risk of a defect in the Lotus unit vs. the risk of an accident due to the defects by design of the OEM unit any time. The Lotus ABS is so superior and furthermore I've never heard of any ABS unit failing so that one needs to let it be replaced. They usually run the lifetime of the car they are fitted in. To all the ones who are unsure or even in doubt: there is no reason not getting the OEM unit replaced. In fact there are many good reasons to do so. Safety for the first.

Mine didn't need resetting even though it was a new unit. It all seems a bit random.

I'm definitely up for one of these after this morning's drive. I switched the TC back on for the first time since fitting TDs 16/17 with R1Rs on as it was raining - BAD idea... it cuts in randomly during even moderate braking and is outright dangerous. I had a close call at 25 MPH slowing for a speed bump going down hill, the NS wheel ABS kicked in big time and nearly spat me into a parked car - I was on 1/2 lock steering to the right just to keep the car going in a straight line. TC will be off from now on in...

[Graeme Lambert]

Has there been any developments on this? G

[Big Steve]

And...how easy is it to swap units?

Rob I fitted mine in less than two mins at the weekend. Four bolts, slide the clip off with the wires and then lift off. Just make sure the cars off and you will be fine.

Doubt you will get a 'new' unit unlocked for less than £450 IMHO. I can confirm though that once unlocked its free to be used as many times as you want. My second hand exige unit has been on two other VX's before mine and can report no problems.

How does it feel? Ice mode gone completely?

[davemate]

Hangar111 can do the coding for you, they did it on mine and it was fine. -thought it hadnt coded, but it turned out to be another problem. just give them a call and say they have dont it before as they have a note on their system -just mention the yellow/silver vx!

Completely gone my friend, has transformed the car and it's braking. The best mod I have done so far, then again my ice mode was constant.

Spikes in the TC system are causing the abs to go mental? What TC do you have??

[cs_]

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.

[dumfunk]

has this group buy been done?

[robin]

no i been to busy to follow it up but i still want a abs unit.

[dumfunk]

add me to your list if they can be pre-programed or whatever it needs doing to it. cheers.
