razza Posted October 27, 2022 Report Share Posted October 27, 2022 Hi all, First time posting on these forums. Apologies if this has been covered previously but I did do a search but couldn't find any info. I am looking to upgrade to a G4X from a Vipec VX ECU. My question is - can I do this upgrade without a re-tune of the car? I assume I wouldn't be able to upload the same .pcl file but is there a straighforward way to copy the data across between platforms without the need for a re-tune. Thanks in advance for any help offered. Ryan Quote Link to comment Share on other sites More sharing options...
Brad Burnett Posted October 27, 2022 Report Share Posted October 27, 2022 I would recommend a retune. You will 100% need to resync the ignition. I have gotten by with a simple copy and paste all the pertinent data. Quote Link to comment Share on other sites More sharing options...
essb00 Posted October 27, 2022 Report Share Posted October 27, 2022 Tune files are totally different for the old software to the current software for G4X. You'll be having to re-do all parameters manually. You also need retune as control algorithms are totally different from old generation Link ECUs to the newer Link ECUs.
