Data Snapshots using the CRT

[Guest Brolliar]

Snapshots - It appears that for ECM Data you can only take one snapshot at a time look at it and then take another ECM Data snapshot. You can't go back to look at the 1st Data snapshot. Is this correct??

All help appreciated.

Good question; and does snapshop sit in the background waiting for the next CEL.?

My perpetual E026 is intermitant lasting only seconds, thus it never can recall back ariving every 3-4 minutes add infinium till I get over 55.

That is right, no stored snap shot, but why do you need a snap shot when you can see all of it live?
