Let me start out, i have a FAST classic, and it has run great for the last couple years. My only complaint is i burn through DB9-USB adapters every couple months, so i keep extras in the glovebox, haha.
Everything has been working great, with the recent cold weather i wanted to go driving and fine tune the cold startup tables. I was able to connect my laptop to the ECM fine, i could read live from the dashboard, and could initiate, read and save a datalog. But when i try to Read a new tune into the ECM, it boots me out. I select a revised tune file and choose to overwrite existing. The progress gets to 11% uploaded, the i get the popup for Comm Write Failed, and the connection gets dropped, but not disconnected. If i ping the ECM, it connects right back no problems, but i will not load the tune.
From the last time i datalog/uploaded tunes nothing has changed on the engine, or on my laptop. Since i can connect and datalog, i figure the ECU is fine. Would my tune files be corrupt? I have tried to load old files from months and years ago, but it always drops the connection. I checked all the power and grounds and everything is good, battery is at full charge, so i am stumped.
Using a Windows7 laptop dedicated to tuning my Syclone, i have the 2303 drivers from FAST, and everything had been working great, until yesterday. Right now i am doing a clean Windows reinstall on the laptop.
Does anyone have any ideas?
