Hey Mike

You're right in that there are plenty of options out there. My first step was to work out how diesel engines actually make more power, as it's not the same as a turbo petrol engine which is pretty much just a matter of adding the right amounts of fuel/boost and timing. With diesels, you can pretty much just keep adding more and more fuel to make more power, beyond that it's a matter of controlling the smoke tables (so it doesn't take off looking like a coal fired train) and the torque tables to protect the transmission.

I found this article helpful:

EndTuning - Tech - Tuning Boxes

I did a fair bit of reading, and decided to go with Bluefin as they've been in the game quite some time coming from Europe where they deal with a lot of diesel performance tunes.

Plus the Bluefine is an actual ECU reflash, where a lot of the 'plug in' solutions are just interceptors that increase fuel rail pressure and nothing more. Anything that has a plug in box that allows you to 'select' the power, is just raising the fuel pump pressure, which will net you 20-30hp before the engine starts to smoke excessively, then they advise you to turn it back one notch. These piggy back boxes don't take into account the safety limiters inbuilt to the ECU (often overriding them) and don't control the torque tables (which can put undue strain on components, most at risk being the transmission). A good re-flash will do more than just raise fuel pressure.

If money was no object I'd take the car to HP-F and get them to do a custom ECU tune. That would net you the most power, safely, and allow you to tune it to your driving preference. The Bluefin is a good compromise, at roughly half the price, you download your ECU data, send it away and they will tune it remotely, then you upload the new map and keep going until you're happy.

I did this with a COBB Accessport on my Mazda MPS and was thrilled with the results. In this day and age, I am not convinced that a stock car needs an expert tuner with a dyno to get decent results. Remote tuning may be a bit more conservative, but you'll still get a decent result. Here's hoping! I might try pull the data down tonight and get it mapped before everyone goes on Xmas break.

Thanks Smokey. I found the same article and just as you have done research I've been at it for a few weeks. Same conclusions broadly. I did have a chat with SouthernBM and they can do the remap for a much higher price than Bluefin.

I actually ended up getting the bluefin and am in the process of reading the current ECO file. But getting an error E008.

Will keep you posted. So far support from Peter at Peter James Tuning (Tigersoft) has been excellent. Hopefully my initial issue is not a big one and I can get my car upgraded.

If not may take it if HP-F. How did you find them?

Mike I have my bluefin installed now. I am very happy with the results. The car isn't going to take down a sports coupe from the lights but it certainly has a lot more urge, the torque is on tap with next to no turbo lag from anywhere in the rev range, the car shifts more smoothly and overall is just a better car to drive. Fuel consumption has gone up based on the display (by .4L) but could also be a change in driving style.

My experience with HP-F is second hand, but interestingly enough it is relevant to this scenario. My mazda MPS I installed a COBB Accessport. It turned the car from a torquey little FWD to a beast on a leash. 200kw+ through the front wheels and over 450nM of torque on a stock setup, launch control and flat shift maps for about $600. My mate got a HP-F tune on an identical car for about $1400. His car pulled even harder and had a much fatter torque curve, it was undoubtedly a quicker car and that pretty much summarises the difference between a remote tune and a custom tune. It's a trade off between convenience/cost and squeezing that extra 10% out.

Is yours a 3.0d or 3.0sd?

Mine is a 30D. It's the last of the 2010 models and technically a 2011 as its fitted with the bigger newer engine. 180kw/540nm stock

It's a great car and has the M sport pack on it.

Good news is I love the drive. Bad news is the over night I found out that the bluefin is not compatible with my ECU. Their UK department confirmed this after I sent them the first read on the car. So bugger dude!!

That's why I was interested in finding out about HP-F. Looking at their pricing a custom ECU remap for an X5 is $1200 atm.

What was your friend's experience with them? In terms of getting it done, customer support, reliability etc?

Cheers
Mike

That's annoying! I reckon, based on that, absolutely go with a custom tune.

His experience with HP-F has been good. He has been back a couple of times to get them to fine tune it, but he has also been going for fastest stock FWD record at Calder ......so he takes it pretty seriously. Obviously you will need to leave the car with them, and like any custom tune where they will be running it up and down on the dyno, with a final road tune - you need to trust them with your car - but obviously their rep is on the line so I doubt they play roulette with your car.

As I said, for your money you're going to get a much more efficient/productive tune. For example on my car:

3.0D (bluefine) = 150kw-> 196kw / 500nm-> 597nm
3.0D (HP-F) = 150kw -> 212kw / 500nm - 612nm

(now I'm starting to think I should have stretched for the HP-F!! MOAR power!! )


I would just ring them up and have a chat, see if they've done a car the same as yours before, any challenges etc. I'd also plan to do a full maintenance on your car before you take it to them, air and fuel filters, oil change etc to make sure it's in peak condition before they start tinkering with it.

Based on their advertised figures, it will be a beast - 230kw and 700nM!! Good news is you also have the stronger ZHP transmission, so that should help you rest easy. My transmission is only rated up to 600nM.

Thanks. That's good advice and I already had a good chat with Matt from HP-F. He was really good so the car is now booked there in early Feb.

Still, Peter James was really good to deal with and has agreed to give a refund plus postage. So all in all it should be all good.

Can't wait now till my X5 is tuned up. It should be amazing by what Matt was saying.
