	ME7.1 read write question? « on: March 01, 2014, 07:05:38 AM »

Every single time I try to read or write to me7.1 I have to bootmode to boot mode them. Never have I once have had a successful read or write threw obdii. Is it just me or is this just the way it is?
Thanks,
Marty

Some time ago I can only read, now, after flash eprom replacement, I can read and write over obd.

Maybe you K-line is too busy, try run a direct k-line from ecu to obd port

Nope, me7.1 is the most stable for me via obd. I use a Ross tech cable and nef, I have probably read/wrote 250-300 ecus easily over 1000 times in the last few years. I can count the number of times I have used my bench setup and bootmode on one hand. Is this all the same vehicle you are having issues on?

Cable?

Program?

I agree. The ME7.1 is probably the only ecu that is consistent enough to trust nefmoto on (excluding the 558S 4.2 ecu in the 2000 A6, that thing is a bitch).

No few diffrent ones few a6's my 2001.5 s4, a 2000 vr6 gti,
And most recent a 2002 allroad. Mainly I use mpps v13... Last night I made some small changes to a file I didn't feel like pulling the ecu out again so I said wtf and tried threw obd2 with mpps went to 100% then failed... The car started once then wouldn't start again... Ended up having to pull the ecu out anyway... Needless to say I wasn't thrilled. Is there other software that's has a higher secess rate? How's that knockoff triboot galletto 2 tool? Does anyone have experience with that?
Thanks for the responds
Marty

95 percent of the galletto's are broken out of the box, chinese used the wrong components and they need fixing. After that they seem to work.
