So i'm gearing up to get my FMIC installed, and after that will be looking to get the car a proper remap. does anyone have any real world experience of what sort of gains can be had out of the M47 engine, on the stock turbo?

I'm not looking for tuning box "claimed" horsepower, I'm wondering if anyone has had a proper remap on an M47 163hp engine, and what it achieved?


also as an aside, does anyone know if the N47 will bolt up to a M47 engine? (cyl spacing and bolt pattern?)


Cheers
Craig

[Gk E92 330d]

I had my 318d 2009 lci remapped at Sedox in Sunderland.

143bhp standard with the remap I had 182bhp the increase in power was noticable although it was only the 318. All over the rev range was better
and for my daily drive 16 miles to work made it more enjoyable. Fuel consumption also increased from average 42/43mpg to 47/48 mpg

My advice is do it. I talked about having this car mapped for nearly 2 years before I had it done. The saving in cost of fuel over the 3 years of ownership would have more than covered the cost of the remap and given you a more enjoyable drive into the bargain.

I have now changed to the 330d E92 with 245bhp and will be booked in as soon as the H&R springs are fitted. Can't wait to see the difference it makes to the 330

What intercooler are you putting on it?

I read on bimmerpost a proper remap is anything from 205-215bhp and around 300lb/ft

Apparently the M47 engine becomes quite smokey after a remap so hopefully the bigger intercooler will help reduce smoke



If you fancy a better turbo theres the alpina turbo from the d3 that matches up. Available from essex turbo's

bought it in the US when i was over for business, and stuck in my suitcase on the way back :P (i packed light!)

turbo replacement is on the back-burner for now :P

black smoke = not enough air (ie a shit map )

[Jase 320d]

Looks good

More than id like to pay, think i'll go the cheapo option of the 330d cooler


And black smoke = too high EGT's, a better intercooler will combat that

[Icekube]

it only cost me 120$ delivered to the US office, and carrying it back on the plane was free :P

black smoke is un-burnt diesel. adding more air is the solution, a large intercooler effectively adds more air because cooler air is denser, so you get more "air" for a given volume

[Jase 320d]

Might as well run some water meth inj too

Nice to see someone making an effort on the 320d

If i had the wonga it would be for me

Better fmic
Bigger turbo
Bigger nozzles
Water meth
Smf and uprated clutch


If only

[Icekube]

ideal spec for me would be a GTB1756 with 535D injectors.

the GTB frame should improve spool (which is the issue with the D3 turbo, and why they went twin turbo soon after launch)

any bigger than that and it becomes pretty laggy and not very nice for a daily (as found to a friends detriment with a 1.9 TDI lump!)

[Jase 320d]

What gtb1756 matches up?

I know what your saying i had a GT20 hybrid golf gt tdi, ran a charge cooler and water meth. Was quite a spectacle once it managed to kick into life

[Icekube]

unfortunately non off the shelf

the "out the box" garrett turbo, has the exhaust flange on 90deg out (as seen on Darkside Development's site)
my thinking is to get hold of a spare manifold, and ask Darkside (super nice like) if they could make me a log manifold for the M47 to allow me to bolt on a stock garrett unit but that's going to be expensive, hence plans are on hold for now :P

so I'm going to get mine remapped with the stock turbo in the mean time, hence starting this thread to find out what i'm likely to achieve

[Jase 320d]

Hmmm sounds expensive! Theres loads of room in the bay though!

Im fancying alpina turbo. They are over 200bhp standard i think?

Surely be able to push 230-240bhp with one of those?
But then what do the injectors max out at?

[Jase 320d]

Oh and i wonder how long it will be until someone chips in that you shouldn't waste your time with a fake 4 cyl bmw and you should buy a proper bmw 6 cyl

Let me know how that goes... I have 330D and i'm thinking about remapping it

[Alex.J]

I have an m47 163hp e91 and it's remapped!

I tried a tuning box too!

Remap is 205hp and 297lb/ft but I can't find the printout of graphs currently to show.

It has next to no black smoke also, which is due to overfueling, nothing to do with EGT's, all though related!

It's a huge improvement over standard, low down power increased and pulls harder for longer!

It's no rocket ship but has made a/B road overtakes safer!

Overfuelling causes black smoke
Black smoke means increased exhaust gas temps

My Error!

[Ajs_435d]

What you mean Error?

Black smoke is simply unburnt diesel thus a waste, I've always said a well tuned diesel shouldn't smoke that much only a little.

You know you want to Jase , how about an emaps remap?, IIWU I'd just do that quite good for the money think its £250

I know, read my previous post!

Error is me correcting something I responded which wasn't truth! My error!

[cwmitch]

I had an e60 with the M47 engine remapped by evolution it went from 163 to 201bhp and 300ftlb and I could really tell the difference, So in an e9X you would be pleased of that I'm sure plus no difference in fuel consumption

I can't believe no one has said this yet.

Does seem expensive and a lot of effort. Why not just get a 330/335d. Is that such a terrible suggestion?

the way i see it, i already have (own) this car, i don't have 10k to go and buy a 330d (dont do finance.), where as little bits of cash spent over time on this car, is perfectly feesable.

i would love a 330d, no question! but its just not going to happen.
