Hi guys sorry but I'm new to haltech and the whole stand along thing.
Question when I do anykind of fuel adjustment is there a special way to save a map? I made some changes to my fuel map and hooked up my laptop a couple of days later and my fuel map was not as I left it.
Any help would be greatly appreciated.

 

When online the changes you make are immediately saved to the the ECU. If you made changes they will be there and there is no way for the ECU to lose them. It's likely you were not online when you made changes. Halwin, and the newer ECU Manager, have a small window at the bottom left of the screen that will say online or offline. If it says offline you are not actually editing the map in the ECU and any changes you make are not being uploaded.

 

Kind of on the same subject, but when I calibrate my stock FD water temp/air temp sensors, it reads correct for the first 3 or 4 starts, but when I leave and come back in a day or so, the sensors read about 15 degrees or more off.
