Hi All,
Just sharing a few utilities I've created for those of you that might be using ATR... these are just small apps that I've used to tune my 2017 STI, make things a bit easier.
Subaru Maf Tune
Corrects maf scaling based on AF Learning + Correction, or WB AFR. Currently supports only one log file at a time.
Download Link: Subaro Maf Tune v1.4.0.0.zip
Subaru VE Tuner
Corrects VE Table based on AF Learning + Correction, or WB AFR. Currently supports multiple log files at a time.
Download Link: Subaru VE Tuner v1.3.0.0.zip
Subaru Load Comp
Corrects the Load Compensation tables to help address the 'stumble'. I've found that the MAF calibration needs to be dialed in as best as possible before attempting to adjust the load compensation tables. You should find that the app ends up making table adjustments around the area where you can feel the stumble, often you'll see two peaks. If you've made big changes to your fuel system I'd probably zero these tables (prior to maf calibration) and then start making adjustments. Currently supports only one log file at a time.
Download Link: Subaru Load Comp v1.3.0.0.zip
Disclaimer - As always, please do a sanity check before using the output of these helper programs. I've used them extensively on my car, but there could always be something that I've missed. If anyone has any suggestions, or runs into any issues please feel free to post here.
