Before you get too far, it doesn't hurt to contact our the tech department to consult with before creating too many logs. There may be more parameters we might ask you to log but those are the main ones that will cover 99% of what we need to see. Roughly 10 seconds of run time is all that is needed. Runs needs to start before and end after area of concern, in any gear. Runs needs to be in 3 rd or 4 th gear starting at 2000 then floor it and take rpm as high possible not exceeding speed limit.
If you ask the ECU for 20 things you may only get 1 sample a second, and while this sounds ok and its not enough to do a proper tune or adjustment to you map. Which provides excellent data for us to help tune your map. Example, you ask it to log 1 thing you will get 20 samples of this each second. If you ask the AccessPORT to collect too much data, its causes the log to run slower. This happens because the data from the ECU can only be collected so fast. What Do You Need to Data Log?Īs we briefly mentioned before, logging too much data can effect how accurate the data is. This allows you to to make more than one while driving your car and keep track of them when you remove them from the AccessPORT. Then the next one is Datalog2.csv and so on. For instance, the first time you create a log, it saves it as Datalog1.csv. Keep in mind that every time you create a datalog, the AccessPORT saves a new file. Removing the log will be explained further down the page. When you are done logging you simply click the middle button! This then saves the log onto your AccessPORT which can later be removed and emailed to us using the AccessPORT Manager software. You will see "Initializing" at the bottom of the display then "Logging". Once data is selected you can start logging by going to Live Data, bring up any parameter, then click the OK button. So please only pick the data we ask you to or leave it set to default, as this will give you the highest quality datalog possible. There are many parameters that we do not need to see and the more parameters the slower the logging is.
You do not need to check off any addition parameters unless we suggest to. This default setup is perfect for what providing the data we need to see. When you are done press the back button and save the data to be logged.īy default we check off the important things we need to see. Simply check or uncheck the data you wish to view. This will display all possible data that can be logged. Scroll down to where Set Data Log List is, and press the OK button. Simply plug in your AccessPORT to the OBD port, scroll to the Monitor icon and press the OK button. These are not things we support (unless they are our parts in question), but it does allows you to better describe the problem to a qualified mechanic. Things like a poorly made intake, a boost leak, bad tank of gas, bad sensor, and plugged cats, are just a few of things we can see with a high quality datalog. Check engine lights revolving around car running lean or richĪ great benefit of the AccessPORT's Monitor function is that we can also diagnose physical issues that come up that could be mistaken for something with the way the ECU is tuned.
This is one of the benefits of buying an AccessPORT from PERRIN performance, we fully support them even after the sale! Common Issues We See: 99% of the time its something we can fix and adjust our base maps so the next customer never has this problem again. With that said, sometimes customers experience strange issues with the way their car runs and this allows us to see what the ECU is doing and if it is something we can tune out of the car. Why would we ask you for a Datalog? All of our custom tuned PERRIN Maps, (purchased separately or with AccessPORT) are made to our best ability and to most common conditions.
