To start the engine is an m30 b35 with a custom wiring harness I built, turbo, meth, and vems v3.6. The car was running before I tore it apart to rebuild the motor, new turbo, bov, intercooler and exhaust. The engine hasent run more than a minute because it needs to be broken in properly and tuned.
Today after I finished wiring in the boost controler, meth controler, and the vems round gauge I plugged in the gauge to start getting it all set up
And everything worked fine. I then realized I forgot the ground for the meth controler so I removed the ground for the serial cable and added the ground for meth.
After that I keyed the car in and the fuel pump ran constantly. I had it set to prime for 3 seconds. I tried starting the car and it wouldn't fire. I connected vems to my lap top and it would go to connect and then disconnect and say firmware upgrade might be needed. The problem is I cant get connected to vems to update the software.
I have tried everything from unhooking the battery, to updating the driver for the serial port to sub connector, and checking all power and grounds.
I am completely lost. I've always had problems with vems not connecting but usually works after a couple tries. I have also had a problem where at WOT the serial port will loose connection and then reconnect.
