I have the data log from tuner pro rt im running a 350 tpi with ostrich 2.0 car has been running fine for over a year now then suddenly the tach was jjumping and car was backfiring and stalling out. took a datalog to see what was happening. please someone help. just change .txt extension to .xdl for tunerpro to read datalog
