YEs and yes.

UPdate to the newest version of software and reupload the calibration to the ECU using the new software and see if the problem persists.

Everything is tested here before they are sold, so it is most likely that it is an ECU issue. Keep in mind that these ECUs are well over 25 years old now.

What is the serial umber of the s300 board inside the ECU.

From Help, About, what is the version of software you are using?

A19 OBD2B

You should save your calibrations to your hard drive so you can have access to them any time. If you have overwritten the file without having it saved somewhere then it is gone and you will have to go to the New Calibration button and select a new calibration to use.

It should be A19.

Post your calibration as well as a datalog showing the issue.

I would recommend that you try the s300 in a known working ECU from another vehicle or a friend and see if it works properly then.

You should use a multimeter and see if the wideband controller is outputting voltages lower than the reading you are getting. This is more than likely an issue with the wideband being used. also make sure you have the correct voltage conversion for this wideband.

That is a possibility. The tuner should be able to assist with settings for that and looking at the datalogs to see what is actually happening.

Yes , but only if your are tuning the AFM.

Have you discussed this issue with your tuner?

I would recommend retouching all the joints with some solder and the soldering iron and see if that has any effect.

Yes full throttle shift is available for that.
