Upgrade you GM Tech 2 clone

Hello to everyone. Now after we spent all our tests GM Tech 2 and made sure it is working then I will tell you how to do so that you have a connection with your computer and how to resolve rs232. Also, if your Tech 2 at the start of the car restarts will tell too.
To begin with, how to fix a reboot your Tech 2 when starting the car. The square dedicated native voltage Stabilizer, black spots, this is how it is better to feed on, immediately giving to drink block, then the main Board gently giving to drink lagged behind in her legs. By means of wooden toothpicks carefully remove the solder prepared under us new voltage regulator (mornsun VRB1205LD-15W DIP). If your Tech 2 does not start, let me know and I will tell you how to fix it.
And here is how to fix the error rs232 and if its not there then an error connecting to the computer. Any chip series max232 sop, often instead max232 is max 202, the same principle, and they differ by the presence of protection. They cost a penny. Also it will not be superfluous to solder the connector pins around the max232.
As you can see, after all these manipulations my Tech 2 became full-fledged. Does not restart, connected to the computer can flash and programming blocks. Good Luck To You.
I would be very grateful for any donations for me, as my gratitude to you, will share his rich collection of materials on Tech 2 , which at the moment a lot of firmware, software to overwrite card, instructions and more. Thank you.
