v4 cant connect

[stevedarman]

I have a VX commodore and cant connect to data log
I keep getting checksum error and truncated error
I have tried changing all the setting i can but no luck
Can any one help?

Assume it is a V6 vehicle you're connecting to? Is it a factory chip or aftermarket? I'm aware of cases where the chip is an aftermarket piece and doesn't work the same as stock (and V4 won't work).

[stevedarman]

Its a v6 stock chip the car is standard

[Tordne]

Are you able to post the full output with errors etc then?

[stevedarman]

I will try again next week and see if i can copy some errors

[stevedarman]

took some data pics this is what i get

One thing that you could try, which has helped others with your error it lowering the Chatter T6 timing from to a value of 10 (often set to around 50).

if your using a VX ecotec with a flash PCM not the L67 memcal PCM then the device ID is $F7 not $F5

[stevedarman]

Hello i have tried changing T6 as suggested with no luck
and i tried changing $F5 to $F7 still no luck]
still getting the same errors

Can you email the text (as you sow in the screenshot) to me at support@efilive.com and I'll forward on to Paul (Blacky) - he's the V4 developer and expert.

Oh, I gather the comms is setup correctly? What baud rate are you using?
