Hello & TDI Tuning box for SD

Post by ultrabelse » Wed Feb 05, 2020 4:36 am

hello!

I bought a well spec’d Agate Grey MY14 SD about a year ago (air sus, pano, 14 way, 20” sport design, extended leather etc, gtechniq ceramic - this was my addition!) and love the car coming from mostly BMW’s. I don’t find it hugely sporty however I think it’s sporty enough for my liking and has a far wider range of abilities than my previous BMW’s being also a great long distance cruiser and the interior has a nice sense of occasion I never felt with BWW.


Thanks to all the forum members for the advice/commentary on options - reading this forum was invaluable in deciding what to look for and buy.

I have read the odd comments here and there wrt the TDI tuning box. It seems to have made a materially positive impact for everyone who’s used it.

I’ve never added aftermarket “stuff” to cars I’ve owned so am instinctively nervous about doing so however I would ideally like to extract a bit (ie a lot!) more torque out of the engine as it can feel underpowered at times.

Has anyone had a bad experience with the box or recommends not adding it? FYI if it’s relevant I have a third party warranty (already paid for itself with a new transfer box) and would ideally keep extending it.

Any thoughts / advice would be appreciated!

I had the TDI twin channel tuning box on my SD and it was very good, I ran it for 45k and then sold it when I sold the car - it owes me nothing and gave an overall better feel to the car across the range when set to the middle setting - higher ones are available if you like :D

For the money you can't go wrong.

Did it impact high speed, plus 100 mph, ability?

I have the TDI tuning box on my Diesel . makes a noticeable difference. my car is due a MoT and Warranty check so have taken it out. i did a round trip of 100miles today . with the box in , the MPG would be 45. today it was 34 without box. !

Have you checked the MPG manually rather than going on what the on board computer says?

The reason I ask is that most tuning boxes either raise the fuel rail pressure modify the width of the injector pulse. The ECU injects more fuel than it thinks and gives a false reading on the MPG.

Most tuning box companies are happy to keep quiet about this as customers think they are getting better mpg when in reality they are not.

If you really are getting that sort of improvement in fuel consumption I would be amazed.

My on board computer already over estimates the mpg by about 4 to5%.
