Looking for R4 (Split Sec) software download - Version 2.0 or newer
As the title stated, I'm looking for a link to download the R4 software from Split Second so that I can flash the AIC1. I currently have version 1.5.0 and need the newer 2.0 or better per my tuner. Thanks

Once your tuner figures out your fuel trims you can scale the PI map in R4.
I forgot the setting but it's there. Then just hit control A to highlight the entire table, then scale it to how much spray you need.
