For the past few weeks I have been trialling a tuning box manufactured by a German company ASA Autotechnik Saretz and I have compiled the attached report giving details of my findings. Should you want more info from me contact via a personal email and I will try to answer those questions posed.



A really special price to forum members has been negotiated with ASA Autotechnik Saretz who can offer a Tuning box, plus appropriate connecting cable complete and delivered to your door for an all-inclusive Special price of € 99 plus shipping costs of €10 to the UK. (A total of €109)

Members in other Countries should check shipping costs prior to purchasing but I have been advised that they will be as reasonable as is possible)



Please Note: -
This is a considerable saving on the regular ASA Autotechnik Saretz Internet price of €148 plus postage.

:beer: Many thanks for sharing this research with us Itsatusconmatey (should that really be Itsatucsonmatey?) I found Ulreke Saretz (Frau /Fraulein?) really helpful. I contacted my local dealer and Hyundai U.K. to find out what the BHP of my 2004 2.9 CRDI was, quoting my registration and Vin Number. Guess what? My dealer told me it was the lower BHP and Hyundai UK told me it was the higher. So I unplugged the common rail connector, took a photo and emailed this to Autotechnik Saretz. She identified the required connection and I was able to order quoting your discount reference and pay using Paypal.But also look at this Autotechnik link http://stores.ebay.co.uk/Autotechnik-Sa … idZ2QQtZkm

The tuning box took two days to arrive and about 10 minutes to fit. I followed your advice to mount the unit using velcro and set the adjuster to 10 to 4 from the start. I have not had chance to do any real testing but I noticed immediately that the engine now seems smoother and the car is more enjoyable to drive. The auto. gear box now seems to change more smoothly and the revs are now less for cruising speeds - a sign that fuel consumption will lower. I recommend that for a little over £80 this tuning box certainly does what it says on the tin...in German!
