Next thing. Purchased a tuning box off a friend of a friend (also with a cast intake - R reg)

comes with a male and female connector for the FIP. And then a vac line that T junctions into the MAF vac line.

Drive home, fitted the box (with engine warm - ouch) and turned on. Fired up but settled down into an extremely lumpy idle and did not run right at all. Worked fine on the other car.

should I of done it cold? Or disconnected battery?

Temperature should make no difference and as long as the ignition was off there should be n problem, there are different versions of the Power Box for different years.

aware there’s ones for different years. But a 1996 and 1997 in theory should be the same?

That I do not know, there have been many specification changes over the years

Had one of those, nothing but trouble.
Got one of these, which transform the delivery. Smooth delivery and no surge when it kicks in.

It’s a non descript black box.
I only got it off a friend of a friend because it worked on his which has same engine and management.

plugged it it fires up but causes the worlds biggest loping idle

I think There were a couple of different ones depending on year.

The later plastic manifold engines have a maf which the alloy manifold don't have.

forgive me for being stupid. But what does the vac line from the ally intake manifold go to? Attached to fuel filter housing

MAF
Mass Air Flow

Ah thanks for clarifying.
In that case the vac line plumbs into the MAP vac line.

You have the right one or the connections would be wrong as mentioned.

wonder why it’s not working then.

I can’t imagine I’ve already got an ECU chip as it does feel slow and about the right power

There is no MAP vac line it is a pressure line.

Plums into that then.

That looks a very cheap and nasty powerbox

I'd be tempted to open it a see what's inside.
