Ok, after much frustration with the serial port driver error message, i reinstalled TS 1.006. I started the app from the folder it was installed in, and it started much quicker without any errors, so i gave it a shot hooked up. It detected the ecu! I honestly have no idea of the real cause for all ...

Sorry i haven't the most free time right now with finals sneaking up and all... I tried the 32 bit in terminal, but then i get the unable to locate serial port drivers issue that i used to get prior to deleting all traces of the serial.lib file, then re-installing and placing in my tunerstudio ...

Using my system profiler, i check for usb port drivers and i do not have a usb that says ...

I finally ended up building a soundcard oscilloscope with my laptop, and i traced the vr circuit to find i missed some flux buildup on some important components, recleaned and now it works great...ignition atleast ...

Thanks for the reply,

Hello, im new to the forum, as im putting MS1 V3 in my VW type 4 beetle. I don't have a stim, but im trying to install the ecu now, and i have most of the wiring done. My relay/fuse box is finished along with the power and grounds to the MS ecu. Everytime i switch to ignition the 2A fuse that sends ...
