For sale is an ECU that has been modified and tuned so that it will function correctly when swapping a FSi engine into your MK1 or MK2 Golf / Rabbit / Scirocco / GTi or Jetta. These are for TFSI Gen 1 engines with a timing belt. We do not yet offer tunes for the Gen 2 or Gen 3 TSI.
We offer 2 versions of this ECU. Version 1 is a swap tune for CDL, BHZ , CRZ or any other engine that came from the factory (such as a MK6 Golf R) with a K04 turbo.
Version 2 is a swap tune for a standard BPY or other Engine with a K04 turbo, injectors and Map sensor upgrade.
When purchasing, please leave a note with the order as to which you’d prefer-
These ECU tunes are professionally done and have been tested for many years in Europe. My personal experience is that they function very well and will make your car scream!! I have driven both personally while watching the AFR and tuning and the tunes are very safe and impressive. I would put them up against any tuner!!
The price is for an ECU loaded with the software. We do offer a $50 buy back of your old ECU - if you have one to offer.
