Handheld freezing during datalog

Hello,
Everytime I try to make a data log the hand held will freeze up in about 1 min and keep from making the log. I have to unplug the unit to fix the froze screen. This is the only time the screen will freeze up.
No matter what I adjust I cannot get the lean tip in tuned out and was going to send a data log to Fitech but came even do that.

Thanks for the help in advance!

I have a very similar problem on my go fitech 30005, fitech suggested I exchange communicating  cable from handheld to throttle body but it didnt work.  My handheld screen still freezes during first couple minutes of data logging.  So no solution as of yet, short of sending unit to Riverside,  then you are without unit for a month or more plus cost of shipping

It was a bad handheld. Fitech sent out a new one no questions asked and it fixed this issue.

however, I still cannot get rid of the accelerator pump shot issues. It either is too lean on tip in, mainly on fast acc. Or when you add just enough fuel to keep from going lean on tip in then it goes way to rich, to 10.5 AFR and stay there causing rich misfires. Im really wishing I wouldn’t have bought it if all I was going to have was issues. I have no problem with carbs but wanted to run boost so went with this. But I will never run boost if I can’t get the NA engine to run right
