Thank you very much for the great answer! I will wire up the both things like described. I want to keep the main ECU harness untouched and therefore I will keep the narrowband lamda. Also, the ST205 does not have a OE boost control solenoid. Kind regards Atreju

Dear Community My name's Atreju and I just recently bought the G4x MR2-V3 for my Celica St205 GT4. My Celica run in the Past with An GReddy Ultimate and an Apexi AVC-R Boost controller and pushed out about 457hp for many years now. But I was never really happy, because the mapping was extremly difficult with the GReddy and the Celica was not running smooth with idle, weather changes and so on. Thats why I decided to replace the original ECU with the piggypack GReddy with the G4x and I want to control the Turbo Boost also with the G4x. The car runs now with the G4x with the basic MAP and now I need to wire in the boost control solenoid from the AVC-R and the output from my Zeitronix wideband Lamda. My question now - where do I connect the Solenoid and the wideband lamda? Do I need to buy special adaptor cables from Link? Just for your information, I just wire the Link ECU and make sure, the basic setting is running to save some money. The mapping itself will be done by professionals, but they want a fully wired and running car. Thank you very much Kind regards Atreju
