Quote from: tets on Yesterday at 09:21I can't help but think the 3 series might be a bit light for towing a tonne of car with 3 / 400kg's of trailer although I could be proved wrong!

The 5 series gets good reviews as does the A6 Audi but not as fun - about the best of reviews a few years ago was the Mondeo but not everyones taste

Yeah the 3 series is close. It can do 1600-1700kg I believe. Having said that, it turns out they are extremely thin on the ground. 5 series presents more to choose from and slightly more in terms of towing capacity.

@Ardent I'll take a look thanks!

Since I posted this an opportunity has presented itself to get into a pickup truck but not 100% on this just yet... obviously a very different proposition and 3000+kg of towing capacity!

Rover 75 estate?
I find them aesthetically pleasing and becoming rare. BMW engines?

Had a bit more time logging / messing yesterday afternoon

Looking at injector duty, knock and air temp

What is impressing me most is the air temp using the intercooler in the gap where the tank used to be

Ambient temps were 19 / 20 degrees and tootling in the village it was reading upto 28 but when I got the speed up it dropped to 24 degrees 
Max average knock is 17 with max peak at 20 so happy with that for the time being
Injector duty maxed at 76% at WOT so I can also cope with that.

Need to keep logging and checking but first impressions are really encouraging

Oh and **ck me it's quick!

Thanks guys & gals.

Can you enlighten me as to what it does? It looks like maybe a resistor/filter.

As C said:

It should be bolted to the cylinder head.

During a rare engine detail session, I found this, erm, what-ever-it-is loose. This is on the left side of the engine. There's an empty bolt hole that looks suspiciously where it should be.

What is this thingemy-jig? There looks like only one wire to it.

The 320i is buttery smooth with the auto box. The 330i is the same car with a higher tune.

"A friend"  who has the same car has had his mapped, also enjoys the better performance & gets 33mpg on 90% town driving. He tells me.

If you're doing enough ex-urban miles, the 330d with the straight 6 N57 gets rave reviews.

Interesting, didn't think these would be in budget...

When I say 330i I actually meant the older generation with a 6 cylinder engine - I have a soft spot for the N52 engine having had a couple of 130i in the past.
