F30 320d Software Remap

My car is in my driveway, it very much exists along with about 6 others for sale on Gumtree and Autotrader.

It’s a 23d, not a 2.3d nor a 2.3L. It’s an N47S Motor, the only difference is stock factory output and the additional turbo which is used to reduce lag and improve throttle response. In SA the 23d was only issued with X1s with Xdrive, which is the most expensive version of the X1, even more expensive than the 28i Xdrive which is why it’s rare.

Given I have stripped my engine bay, more times than I care to count, I am likely more intimate with the workings of the Motor than anyone else, I know the difference between the two.

It shows that one learns every day, It is my first time to hear of the 23d and thanks for the info. I assumed your car was the 20d with the same engine as the OP's car. I know of the 20d, 25d, 30d, 40d and 50d on the X5 models

My VIN decodes as my vehicle having the N47S Motor, which I assume is just a revision of the N47D20.

I will go film a quick video for you guys of the Motor if you like, it’s quite the Motor, I specifically looked for it when I bought my X1.

I'm not sure if I really like the exhaust sound but well, I must just get used to it, but I'm happy with the benefits on the turbo (& the engine).
it seems like my fuel consumption is a bit high, unless the engine still needs time to adjust after sw & dp.
Makes me feel like sw alone was a way to go but I guess it's still early to make such conclusion.
Are u sure fuel consumption went up after the dp install? U sure u not riding a bit faster cause it does give u a significant power increase. Who did the software map for u?

DP definitely does not give a significant power increase. You’d be lucky to gain any power from fitting a DP.

It does make it more responsive.

It also changes the exhaust note which was why my fuel consumption went up...just couldn’t help but step on the loud pedal.

Well maybe it had to do with my driving as well after the dp as I wanted to feel the power difference but I since reduced the weight on my right foot to try monitor it properly, I even did a reset on both the journey and onboard computer readings. It used to be between 4 and 5.5 on highway but I've been getting between 5.8 to 6.7 on the highway.

K Spec did my sw and downpipe, (someone said it's actually Powerflow that did my dp, K Spec must have taken the car there apparently).

K-Spec guy said they gonna write another file for my sw, something a bit powerful.

Have you mentioned you feedback about the consumption to the tuner? More power normally equates to more fuel

Under normal driving conditions the car should be more economical, granted if you use the extra power don't expect the same

Assuming the tuner changed the low throttle maps, if they weren't changed, they should at least be as economical as it was.

Ferdi, wen u did the dp on ur car, u noticed better response & a change in ur exhaust note and yet u say it does not give a significant power increase? seriously???
Are u gona be the 1 guy? :)

How does a different exhaust note and better throtte response equate to more power?

My car in fact gained 0kw and 22nm - that is a mere 3% increase in torque and none in terms of power. Gaining 22nm on 730nm isn’t significant by any stretch of the imagination..

Some time I think its just in the mind when you do an exhaust/DP. :fencelook:

CONCLUSION: Ferdi u remove ur dp and reinstall ur cat. EVERYBODY else install a dp/remove cat, get a software upgrade an experience significant power like ur car was meant to hav. (Wen u out of motorplan ofcourse)

I can also confirm. I have a DP, with the mid box removed. Car is stock otherwise.

Only noticeable difference is sound. The "extra" power is all in the mind, placebo effect. Call it the same as that 22kw you gain from installing fanatics stickers. You can feel its there, you tell everyone its there, but is it really there? :)

Downpipe on a diesel with software, will improve the low-down torque and keep the EGT's lower

Removing the restriction of the DPF will definitely drop EGT's. I also cant understand how removing restriction will see a zero nett gain.

Lol, I’m speechless bud...

Probably because my IQ just dropped after reading that message.

Exactly as I said. My car gained 22nm.

Not yet, i had intended to give it a week or so then let them know. I'm driving to Lesotho over the weekend so that long drive should clarify some questions as well.
