ECU Securing Arrangement

[Midge]

Am I right in thinking that the ECU and associated wiring looks like a right dog's dinner? And should the ECU itself be secured?

[ribol]

Mine is held in place by two methods, gravity and friction, not TVR special parts available in all good Motor Factors

So it is quite "normal" to have the ECU bouncing around?!!!

[raceboy]

I think 'wedged' is the correct term, and keeping a TVR theme
Mines on top of battery box wedged under the dodgy looking brass pipes, and all held in with the passenger foot brake board

[Graham]

wedged i dont know... Its a specialy designed mounting facility built by TVR using a low binding method to reduce harmonic vibration.

which ***might*** look to the untrained eye as if its just wedged next to the battery and held in with a bit of carpet

They're all different. They're all crap. Depends on when your car was built and whether Frank, Terry, Denzel or Sharon was in charge of 'ECU stuffing' on the day.

My particular favourite is the spectacular decision to run the heater pipes above the ECU, and punctuate their travel with poor quality pipe junction / wormclip affairs. The first failure will result not only in an annoyingly wet footwell, but some tremendously exciting short-circuiting.

dont worry simon they all seem to be like that ,i spent ages just tidying up the crap wiring loom that sits next to the ecu and there just dont seem to be anything to attach it to ,so i stuffed it in the gap next to the battery on its side with the connecter on the top to keep the water out if it should ever get wet in the car ,then tidyed the rest of the loom with tie-wrapps ,not the crap ones used on cars but decent aircraft quality ,and treated all the connectors with contact grease which is made especialy for this just to keep the damp off the electrics as tvr's seem to suffer from lots of elec probs ...

Whats this contact grease thingy, if you don't mind me asking, a trade name would be usefull if you have it to hand.

i use it on the aircraft that i work on ,will get the name but doubt if you can get it as its made for boeing ,a company like radio shack or maplins should have some in stock and contact cleaner ,its just one bonus of working in the aviation industry ,cant have things breaking down in the air

Mmmm...yes...I once braked hard after reversing & the whole ECU box came whizzing out from behind the footwell cover (much to passenger's surprise ). Car still went, mind you. Drove it around like that for a good few days before doing me own 'ECU re-stuffing'. Could be an Olympic sport...
