Title: Cable issue?
Post by: armageddon on April 10, 2021, 08:36:15 AM
Hi all.

Was using the same ftdi based cable with nefmoto and me7logger since 2013 till mounth ago when it stop working/recognized

Prior to this, it was working flawless, both on car and on bench

I'm at the third cable (ft232rl) and can not get it to work, cable is recognized but can no get conection on nefmoto and with me7logger error 0x4.

On the bench it works fine though.

I am assuming that it's a cable fault , but who knows...

Additional info

Same cable, same car but different pc and it works fine in car.

What could cause this issue?

No modifications to car, same drivers as old cable, how can it not work on usual pc but works on other?

Most likely a driver issue, or wrong com port specified.

I thought so, but then tested on bench and works fine.

Test cable latency with VCDS lite

Try 0x00

Already slow - 0x00 as has been since 2013 and with prj pach to be able to start log with engine running

Test cable latency with VCDS lite

Latency test is good at 4.5ms but cannot access to engine module, works fine on the other modules though.

My other replica vcds works fine on all modules.

I was with same issue, bur my latency test was poor, than I buy BMW K+DCAN and since than no problems.
I think is best to make own cable

Good call on the bmw cable, mine arrived today and all works fine again.

It was definitely the cables at fault, the 6 year old chinese kid was probably having a bad morning when made them

Thanks
