Where does the ecu go?

[Aussie John]

Putting my griff back together, does the ecu sit between the battery and passengers feet, on top of the battery or somewhere else? Is it bolted in? cheers, John.

Usually sits on top of the battery. Be careful there's no chance for anything to short out.

[Jay Ayegees]

No - it is slotted in between the battery box and the transmission tunnel.

Even if the battery is on the floor or up in the footwell, as Jigs says it should be wedged in alongside (removal of the bracket makes it easier)

The bin is a very useful location tho

Two opinions here, I dont see that there is enough room to fit next to the battery near the tunnel, mine is a 5l preserp, any differences? John.

Should slide down the side if the battery, it is tight, but its meant to be , nobody likes a pendulum ECU....

It originally was fitted down the side of the battery and the outside of the footwell but the addition of some bits now prevents that.
Heath Briggs says his prefered location is in front of the battery as he's seen too many shorted out on the battery. I guess the only safe way to put it on top of the battery is to make a small shelf to put the ecu on to prevent any danger of shorting and a fire.

The later Griffs have the ECU just floating on top of the battery, the earlier ones there's enough room to wedge it between the battery and the transmission tunnel.

Quite frankly the Griff wiring is pretty poor in this area and looks like it was installed in about 10 minutes, my wedge was better.

On my 99 Griff 500 it came from the factory with it stuffed up on top of the battery. That's where it has stayed. There is a rubber flap and carpet between the battery terminals and anything else. All seems ok.

..and when the silicone 'bodge' comes off the live fuseable link on the fusebox you have another source of danger...

The battery appears to go hard against the tunnel and although I can push the ecu partly in down the other side, it backs up against some gubbins [ maybe some sort of heater motor or valve] so maybe its a " sling it on top of the battery job", any further advice or coments welcomed, I assume the relays etc attached to the wiring sit where they end up! cheers, John.

On my (6 it sits on top, AS with yours no room on the right and on the left there is Heater stuff bolted to the car. Mine has a flap of carpet that sits over the top of battery. Have seen some battery covers about that may be useful to protect it from possibly shorting the ECU.

ditto - and the carpet has rubber glued on the inside.

[Aussie John]

Thanks guys, I seem to remember someone going to put the ecu in a plastic lunchbox or something like, a good idea perhaps?

[pjac67]

Mine (5L pre-serp) sits upright between the battery and the carpet ie facing passenger seat.

Hi,
I found my ECU wedged high up between a ledge and inner wing top above the battery; the ECU plug resting on the lagged heater pipes. Seemed like a good place away from the battery with no chance of it falling down. This left enough room for the remaing loom to lay across the covered battery without having to jam every thing into a tight spot. I put some more heater lagging material between ECU plug and heater pipes to stop any heat soak.

We so far have ecu,s situated in front of the battery, behind, on the left, on the right, on top of and up above but not on top of; is there anything standard about tvr,s? Thanks, John.

The grin?

My local AA man (another story) almost had a coronary when he saw the ECU stacked neatly on top of the battery, providing a handy link between the terminals. The offcut of rubber matting had dropped down the back somewhere....
