ECU Security

Following on from the kitcar theft thread below, has anyone come up with a kitcar ECU which can check for a security condition being met before starting up?

I was thinking jolt/squirt code could be written with this in mind. At the simplest this could be looking for a contact to be made (imobilizer, hidden switch, keyless go etc), or if someone went all-out it could even ask a transponder/key for a rolling code.





Any resemblance to real persons, living or dead is purely coincidental. Some assembly required. Batteries not included. Contents may settle during shipment. Use only as directed. No other warranty expressed or implied. Do not use while operating a motor vehicle or heavy equipment. Subject to approval, terms and conditions apply. Apply only to affected area. For recreational use only. All models over 18 years of age. No user-serviceable parts inside. Subject to change. As seen on TV. One size fits all. May contain nuts. Slippery when wet. For office use only. Edited for television. Keep cool; process promptly.

Yep, I can go one further.
My last Sylva had a zetec which was run by a Dunnell ECU. £450 in 1997.
It was fixed to the inside of the bulkhead in the cabing using velcro.
Took it out of the car every time I parked it up.
No ECU is the best way to ensure a non starting car.
Having said that, if they want it, they'll still take it.

With Megajolt the car will run at 10 degs straight off the EDIS so you would be better off with the EDIS isolated.
Anything can be nicked, it is really about making it bloody difficult so they give up and go away.
Apart from the different electrical isolators i have i also have a big yellow handbrake to gearlever lock.

Hidden multi pole key switch to switch:

Feed to Edis
Feed to ECU (?)
and Feed to Ignition

Plus youd have a key operated ignition, so i reckon that is as far as i would go. If they really want it, theyll find a way of getting it. Just hope the Fkers drive it under the front of an HGV on the first Left Hand bend.

Something visible is always a good option. Otherwise they'll get in, wreck the ignition and then give up when it's not working by which time they've had a good rummage and damage going on.

Maybe you could wire something up so you have to press the brake and clutch together, like the bikes (mine had to be in neutral, a PITA when you stalled)
