I recently got my 6.0L bu runnin using holleys hp efi and I used the 1.5 version they gave me, I was just at nmca this past weekend and one of my friends was using a tablet with the new guage feature with his V2 software for his guages. So I came home and wanted to do the same. dpwnloaded the new software and firmware. went and connected the laptop to the ECU to update the firmware, everything was going smooth and the laptop said everything will now reboot.... I sat there for 10 min and nothing happened. so I exited out and tried to start over again and the laptop would not connect to the ECU. now the ECU will not even turn my fuel pump on or anything. it seems to be lifeless. 45 min before I tried to install the update the car was running fine. ive tried multiple times to re-update the firmware but it will get all the way past sending the BAN binary then as soon as it starts to send the BAN header and flash the ECU it says it cannot connect to ECU. Even when the ignition is on and I plug the laptop in it will not go online to the ECU cause it says it cannot connect to the ECU. im lost because ive read over everything and tried everything and im just hitting endless brick walls. any help is much appreciated!!!
