    Increased emissions light again

    Smoke test the inlet system. That would be my first port of call. A small intake leak can cause this. Have a ring round the local garages to see if they can smoke test, or failing that I can do it but I’m a bit of a road trip away!

    Silly mistakes that resulted in lots of swearing

    Talking from experience, the other way you can mess this one up is smash a screwdriver through said oil filter, spin it off and the go to fit the new one to find out it’s the wrong one. And you no longer have a vehicle to drive to the parts place to swap it.

    Anyone used ecotune?

    350-400BHP is easily possible with a turbo. A fuel pump would more than likely be needed for the higher end of that scale though if your car has the R70 pump as standard which most do. R90 from a pre-LCI 535D is a relatively easy upgrade. The Wagner Tuning DPF and Intercooler lit is good value. It seems expensive but the fit is perfect, I’ve never known an intercooler to fail and the downpipe is well made. Good quality welds and steel.

    Re Mapping G31/G32

    Apologies for the delay replying I thought I had post notifications on this thread! In respect to power on top, yes, we are limited in what we can do with how stretched the engine is to begin with. Big gains are hard to make on the higher tuned 4 pot diesels when they're all very similar engines to begin with. Yes tools are now becoming available for it. It'll filter down more and more eventually as other tool manufacturers crack it. We are hanging fire for the minute due to long wait times from the tool manufacturer. We've been told an estimated 20 week wait time between order and delivery, I am talking with our current tool manufacturers at the moment to see what their progress is on MD1 and MG1. If they have something in the pipeline already that will allow us to jump the queue (effectively) we will be able to offer at an even more reduced price. I'll keep in touch, and I have turned on post notifications for this thread!

    A cool E36 .........

    That would be the man yes.

    Coding

    Get yourself a cable and I can show you how to do that over Teamviewer. Once you've picked up the basics it's easy to learn where to go on your own.

    Re Mapping G31/G32

    Yes it will. Gains wise I'd like to say in the region of the 30-40BHP range on the 520D. In regards to visiting the dealer, the remap can be hidden in the engine ECU in the same way it is done on the Fxx cars - the CVN (a calibration number for the engine map that will change if any software changes are made) is locked so it will match the standard engine tune. However that does not mean other ECUs will not log higher torque loads, acceleration loads etc. From a quick plug in as it stands BMW won't be able to tell it has been tuned, however if they want to dig deeper (for example start logging data and look for peak outputs from the driveline where they will see higher than standard torque for example) they will be able to find it. It would be best to take it as it's hard but not impossible for them to find, and it will cause you warranty issues if they do. The torque converter isn't weak as such, it's on the specified limit by ZF from the factory. They state 500Nm max engine torque in a petrol which is bang on what the 540i knocks out, however the boxes and torque converters can and already have been taking well over the standard output in a variety of cars for a long time. The 8HP45 used in the 1 series and 2 series with the 35i engine certainly doesn't struggle.

    The new project and not a 5! - 2006 E65 730D

    It was a pleasure to meet you!

    Re Mapping G31/G32

    *bump* There is a lead time on the tool and the production runs are limited on the tool which launched at midnight yesterday, but we are now looking at buying one should there be enough interest. As I'm sure you can imagine it's quite a large investment for us so we'd need to confirm some interest first. We'd like to get 10 names confirmed that would be inclined to go ahead with a remap. This will cover Gxx chassis and Fxx chassis cars (140i for example) with MD1 and MG1 ECUs. I was in contact with a guy I work with in Luxemburg today who started work immediately on a stage 1 and 2 for the 140i. ECU - MG1CS003 Standard - 340BHP/500Nm Stage 1 - 400BHP/580Nm Stage 2 - 420BHP/620Nm If you're interested, please put your name down on the list. Edit - we're looking at a ballpark figure of £600 INC.VAT for tuning, just as a point of reference for people. 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - 10 -

    What's being worked on today?

    *bump* We get asked an awful lot of questions regarding economy increases in tuned engines. More specifically diesels doing big mileage, so I've got some information from a car taken at random from the car park, and worked out some sums on it after chatting to the owner. The car in question is a long wheel base Jaguar XJ. 2015 reg with the 3.0 diesel engine. Now remaps can have a big effect on fuel economy. Depending on how they're driven, for better or for worse. If you're using all of your new extra power post remap, you won't see the increase. When driven sensibly, for long distance cruising for example, you should do. This car does a lot of miles, the owner works for a printing company and the car spends a lot of its life on the motorway. He estimates around 40,000 miles per year. So 40,000 miles, at an average of 45MPG with the average diesel price around here being 131.9ppl works out at £5330 per year in fuel, or just over £440 per month. A stage 1 remap when driven sensibly in a diesel generally causes around a 10-15% decrease in fuel consumption. This is a big heavy car that spends lots of its life cruising, so we'll go with an in the middle figure at 12% saving. This takes the average consumption to 50.4MPG. If we work that out again, that same 40,000 miles post remap will come in at £4758 or a fraction over £396 per month. A saving of £572 over the year, or the best part of £50 per month. The remap can be programmed through the OBD port, so would cost the customer £276 inc. VAT. In just over 5 months the remap will have paid for itself in fuel savings.
  12. I was really confused as to what a rear bra was, I'm almost disappointed. We have a workshop runaround - a 55 plate Mondeo ST diesel with intergalactic miles on but it just keeps going. No matter how much abuse, on the limiter from cold, you name it it just takes it and keeps on going without complaining. I was staying late Thursday night last week so thought I know I'll give the Mondeo a wash, it's been that long it's matt silver not metallic anymore. I got as far as spraying it in TFR and the heavens opened. It was the first rain in about a month and it was bouncing off the floor it was that heavy. It got a wipe round with the soapy water and then left in the rain to rinse off.

    N54 twin turbo conversion project

    Wonderful project! I don't think I've heard of any others being done in the UK previously either. Are you upgrading anything whilst you're in there or literally just putting the standard engine in?
  14. It sounds like the sump gasket or the connector at the electrical connector (name escapes me) if you have a leak from the gearbox. If it's low on fluid because of the leak that way well be causing your issues. Again not guaranteed but it does fit the bill. The correct level is imperative on these. If you think it's leaking fluid get it looked at sooner rather than later. In regards to them pulling away in second, they will SOMETIMES. There are maps built in to the gearbox ECU that recognize situations like traffic jams and stop start traffic when it's go and stop all of the time. In this instance if the car thinks you're in a jam or stop start traffic, it'll pull away in second to give a smoother drive. It will also pull away in second in some other situations, but for the vast majority of the time it'll pull away in first gear.
