Re: Question about training/using PEC on GM-8

Does anyone know what the maximum number of corrections are that can

be entered in any one PEC session. At 8 minutes long, 10 corrections

per minute would be 80 corrections. I'm sure there must be a maximum

number it can store?

Use PemProV2 software, it has a 60 day trial period.



Some users report that turning on PEC increases the drift, I havent seen this with L4v1.05 firmware.

Thanks,



Looked through the PEMPro docs and it does look like a complete solution. I'll have to put it in my budget. Until then, I'll try following the Gemini manual's method. I'm still fuzzy on how the "Current" and "Backup" data sets really work, but with a little experience I'll probably figure it out.
