Tuning is fun. U know what happen to your engine your engine character. The important thing is the A/F ratio.
The SMT5 have a problem when your change the battery or your battery low-voltage condition. The Global setting will change. But that don’t give any effect just u cannot change your setting. U have to reset the SMT and upload it agent. But how many times your change your battery at least 2 years.
Budget small maaaa… smt can control fuel and ignition. If not I have to buy SAFC and ITC.
