I recently got a s300 version 3 and had it professionally installed in the ECU(P06) I installed SManager on my PC running on 64bit windows 7, then went out to the car plugged my ECU in to the car turned the ignition to ON(II) and plugged it into my laptop. It said "the s300 usb driver is not installed correctly click here to update it"...clicked it then a few seconds later it said "could not update driver" and then nothing after that. I'm not too good with computers but get the basics I did go to the help section of hondata I can't seem to find "s300" under my USB controllers or other devices. the car is a 94 integra gsr



thanks, new to EMS's

 

Download and install the S300 USB drivers from here.

Since it is a V3 s300, go to the widows device manager, find the s300 listed, right click and select update driver, say no to windows update, install manually from a location you specify, then navigate to the smanager/drivers directory and it should install from there.

 

Well I took it to Teknotik(big name reputable shop around here) their tuner couldn't seem to get it to work we tired a new ECU core even and his laptop which is used for tuning on Hondata regularly. Could be the board it's self so they're calling Hondata on Monday to see what's up.

 

The s300 v3 uses completely different drivers than the old s300s. If you do not manually install this driver then it will not communicate.
