Hey guys,
I have an issue happening to me on a car, seems that randomly while driving the LCD will go all screwy and garble the numbers around and make the LCD screen look all messy. At the same time that this happens, if I'm connected to my Laptop and in MT it will be disconnected and won't be able to reconnect unless I restart the car (ign cycle on/off).
I pulled out the ECU and checked all ground and power connections. I checked the log file(s) that were running when it happened. Nothing strange happens to the car (or shows in the logs for that matter, the log just ends clean as if I turned off the logging) and the car continues to run flawlessly.
All grounds on the ECU are good... checked all pins for the COM port as well... everything seems alright (approx 1ohm resistance from end to end).
I thought it might be my laptop causing it, I left that unplugged but I was able to see the LCD screwed up so I know the same thing happened. Then I thought it might be the LCD, so I disconnected the LCD and just plugged in my laptop w/ MT on, and same thing MT disconnected after a while.
It is random though, it doesn't happen at the same time every time. Also it doesn't happen if the motor isn't running (I left the ign switch on for about 30 min and MT and the LCD were fine), and it mainly happens within the first 2-3 mins of driving.
Spec's of the car:
9:1 CR
forged pistons/rods
GT4088R turbo
3" turbo back exhaust
86# LOW-Z Siemens injectors (using 2x Honda Resistor boxes)
VEMS V3.3 w/ 30V flyback running 1.0.73 16x14 tables
Electromotive 3x2 DFU's
Stock 60-2 crank trigger, no cam sync.
I will post up the config & log file later tonight as it's on my laptop.
Thanks!
