ive been having this issue for some time..Most of the time it would only happen at high RPM, now it happeneds all the time...i have tryed 2 different laptops both do the same thing...laptop i usally use is a gateway solo 5150 and the other is a dell inspiron 5100 anyone have any idea on what the problem could be... its really annoying...and it will work again if you unplug the usb cable and plug it back in ...then it will work for a few mins and freeze again...please help!
Is it just datalogging or Smanager as well ?..Typically if you get booted out of Smanager or Datalogging freezes.. There's electrical interference in your ignition system ..
You need to make sure you have a USB 2.0 or better to keep up with the data transfer rate. I had the same problem with my Dell. I added a PCMCIA card with a better USB port on it and haven't had any problems since.
how can you tell what type of USB the computer has...i usally dont use the dell i use the gateway but i tryed the dell and it does the same thing... the ignition system on the car is stock...i even tryed the managment on another car (same car different motor) but it does the same crap..
Delete all of the on-board saved datalog files and disable on-board datalogging until you know you'll need it. This was the main cause of the datalogging freaking out while we were on the dyno.
Use ferrite beads on the USB cable to help with signal retention.
diddo on what ben said, if even got near full throttle while using a laptop the smanager started freakin out sayin my rpm was 36,435 and shit like that.
It came down to on board data logging switching on that made everything go crazy.
disable your on board data logging and try it again.
In my racecar the problem was caused by the wiring. Grounds were not working well so I had to scrape the paint and ensure all grounds were secure. Made sure engine ground was ok. Everything is fine since.
