DATA LOGGING 101 FOR YOUR HPTUNERS MPVI3 PRO AND STANDARD MODEL
What to do when you do a data log:
First thing to do is connect your MPVI3 to your vehicle. Next you want to open the VCM Scanner. When you start your data log you will need to hit the red circle to start recording. You will see it connect and add parameters and channels. You will then see it recording data.
Now this is where you must really do your part. You will start the vehicle. If the engine is cold please let it warm all the way up to operating temperature, so the O2 sensors start working. Once up to temp you will go drive the vehicle. Regular stop and go driving! What does this mean? Simple, regular driving like you are driving through town, stopping at stop signs and/or traffic lights. Getting on the throttle with constant throttle; not just stabbing the throttle over and over. Stabbing, erratic throttle and/or TPS signal does not give us a clean data log. You will also do some 0-50% throttle during your data log. Do not go wide open throttle until we have reviewed your 1st data log.
Once you have completed your data log you must hit the blue square at the top to stop it. You will then go to the left and click on File. You then will select “SAVE AS”. You can then name your data log and tell it where to save. I usually save to the desk top so it is easier to find when you go to send it in an email.
Once you have made and saved your data log you will then send an email with the data log, and a new read of the tune attached to Ryan@FRPTuning.com. We will review the data log and adjust the tune as needed and send you a revision.
We have another blog with helpful hints of things to check before you start tuning be it email or dyno tune. These tips help ensure you have least amount of issues when doing tuning and data logs.
