Does it have 2 serial ports? One to connect it to the utec and one to hook your laptop too? If thats the case then you have to connect your laptop to the tuner to datalog right?

One more thing. Isnt the utec supposed to log the afr. Well atleast the afr that the ecu logs. When ever I datalog is leaves the whole column blank. i just didnt know if that was right.

Thanks

The Tuner Pro connects in series to the UTEC. You will need to connect your laptop via a usb or serial connection to the serial port on the Tuner to do your logging if you want afr readings. Without the tuner hooked up, you will get everything except afr readings. I hope this helps.

 

I would also recommend you do some logging in ecu mode before you really put the map from TXS to the test. You might find that the TXS map it is a little lean.

 

I will keep an eye on it. I dont think it would be lean where I live but its possible. Im about 3300ft above sea level. Thanks for the help
