These ECU's are built by Sean Treacy in Europe, who's been making them for years. They have the following deleted:
 
EGR
MAF
Immobilizer
Shut-off Valve (SOV) (The engine will still shut off fine)
 
The stage 1.5 is to max out the stock turbo so it flows at its limit. It can make 220 HP (crank), with a very big midrange increase over stock torque.
 
The stage 2 is for using a bigger turbo like our Hybrid Turbo, Borg Warner S252SXE, Garrett T04E or Holset HX35 8cm but keeping the stock 6mm EDC injection pump. An OM606 can make up to 280-300 hp with these turbos.
 
Stage 4 is for upgraded turbos and injection pumps. You'll need a 4 bar map sensor for it to function properly, that can be purchased here.
 
In order to have tuned ECU's available, a core ECU was used. When you purchase, you are committing to send us your stock ECU. We'll provide a pre-paid return label if you're in the USA. There is a $100 core deposit included in the price, so when we receive your core ECU, you'll get a $100 refund.
 
If you already have a Sean Treacy Tuned ECU but want to change stages, you can buy the desired stage ECU and send in your old tuned ECU for a $440 refund, so you only end up paying $100.
 
If you are in Europe or the UK, we can ship your ECU from the EU and save on shipping. Use code "Europe" at checkout for $90 off.
 
If you need an OM605 ECU please email us a photo of the label on your ECU.
 
If you need an ECU for a G Wagen, please e-mail us a photo of the label on your ECU as well as your VIN.
