Battery brain fitting?

[Mattt]

Anyone got any tips or photos?

There was a thread on this a while back which if I remember correctly was about fitting battery brain gold.

I can dig it out when I'm back home later this week if you want.

I found one that a Tuscan owner had installed. It seems passenger footwell is the best place? Battery area seems very tight.

I've wire my trickle charger into the interior overhead light. Easy to access from the boot, that is if you haven't got a Tamora..

No power in my new garage, hence the battery brain.

I installed one last year.
It's great, works perfectly and I didn't have to cut any of the original battery cables.
The fob's are a bit flimsy and I've had both replaced at no cost but apart from having to set the clock and radio stations every time I get in I think it's worth having if you have no way of trickle charging.

Have you got any pics or tips on how you did yours?

Hi Matt
This thread has details:

It was pretty easy - I put mine between the battery and coolant overflow.
HTH!

Would using these have a long term effect on engine ecu being left without power.

Sort of.

There is a chip on the ecu motherboard that's used to store adaptive fuel maps. It's just a ram chip that uses an embedded battery to remember its stored data in the absence of main power.

Normally, main power is always available so the embedded battery in the nvram never gets used.

If you disconnect the main battery then the embedded battery in the nvram kicks in and makes sure the adaptive mapping info is not lost.

The embedded battery should last 8 years.

Once it fails you loose the ability to remember adaptive mapping information. BUT only if main power is disconnected.

A replacement nvvram is 12p and adaptive's re learn in realtime quite quickly anyway.

I have one of these spare now as I sold the car before fitting - it's the remote control version.

PM me for details
