With everything plugged in and the ignition in the on position, go to the Help menu and click on “send feedback”. Include a detailed description of the issue.

Has the ECU been jailbroken?

Try deleting all saved datalogs and then make new ones and see if this resolves the issue.

How are you determining that the multi-tune is not working correctly?

It could be any number of things. You should use a multi-meter to check the voltage and see where it starts fluctuating.

How exactly are you determining this?

I'm sorry, but there are currently no plans for the MDX.

The battery voltage is fluctuating constantly and it should be more steady.

The short term trims are going wild when this is happening as well.

Post a picture of the P06 showing the inside of the ECU.

The other ECU's are not compatible with the s300.

Post the calibration as well as a datalog showing when this is happening.

What is your FlashPro serial number?

With everything plugged in and the ignition in the on position, go to the Help menu and click on “send feedback”. Include a detailed description of the issue.

Try raising the torque limit to max.

Some areas were not actually at WOT as the throttle was not fully depressed.

What is the part number of the ECU you are using with the s300?

You may need to have the AC system tested to make sure that it has the correct pressure to operate.
