Cant connect - Tunerstudio RS232 to MS2 Extra

Post by linards »

Hello everyone!
Can someone tell me what i am doing wrong/missing?
Tunerstudio v3.0.22
RS232 to USB, ECU - MS2 Extra 3.4.2
Driver: PL2303 Windows Driver (prolific)
In device manager COM1, tried 9600 and 115200 baud
Buffers - 1, also tried without FIFO

portcheck.exe - no connection made
auto detect in tunerstudio - no controller found
HyperTerminal - just blank, cant write anything

Tried 2 computers - Laptop and iMac

But the thing is my friend can connect with his laptop using same usb (win10)

Any suggestions?

I read some time back about an issue with "fake" prolific chips from prolific. The driver sees it as not legitimate and sets a bit that disables device. If you roll back driver to one with a date of 2008 ( if memory serves me right) that driver doesn't disable converter. Worth a try.

Hmm, USB is working, i tried in hyperterminal and portcheck, i am getting signal back ( i Add it screwdriver to 2 pins :D)
But thats all... Tunerstudio & portcheck cant detect firmware
Yes ignition is on
I am confused :?

But when i connect USB to MS then i am not geeting back any signal in hyperterminal anymore, thats is right?

EDIT: Ok, looks like i dont get any voltage on connector (from ECU to PC) where it connects to pc

Where did you buy the USB to serial adaptor? If from an MS dealer, should be OK. Others may not. Have you got access to an older desktop with a proper serial port? If that works, it would prove your adaptor is at fault.
