A40 Full Read option

[GMPX]

I will email any failed files or successful ones

Please don't, they will either work or not, just let us know in here thanks.

Actually, what you could both try if this isn't your set up, have no other modules on your bench set up, the Allison is using 29bit CAN where the ECM's are 'normal' , it might be that with two modules on the bus talking different CAN protocols over that hour something gets messed up. You need to put a CAN load on the TCM if it is the only thing connected (120 Ohm resistor over CAN H and CAN L).

I think there might be more to it than read errors, the files from TIS also fail checksums for some OS's, back to the drawing board on this painful one

My harness mimics the CAN load from EFI Connections

Tried 2 others today, resulted in the same checksum errors. I have not yet had a successful read.

We think the issue is with some OS's not enabling all the checksums we validate. Off the top of my head there is six, on the files that are failing it would appear that some are not actually used (therefore they have a zero value), currently V8 doesn't realise this and simply assumes the checksum is not correct. We are going to have to put in place some system to check what checksums are active and what ones are not (assuming this is the problem).
Hopefully the three people that want this appreciate the amount of hours we have to put in to this A40 'full read' option once it is done

There's more, we just keep our heads low, read, and wait

Ross.... We have to you thank for everything we have.

You are very much appreciated.

If I had your job I'd be cross eyed.

Thank you.

Hey Chuck, I was just about to sit down and add in 1,000 T43 tables, but I think I'll keep working on this A40 issue instead.

[Chuck CoW]

Ok fine.... Then I don't send your birthday present....

But tonight I'll be sending you some T87 cals tonight...... GET TO WORK MY BOY!

GET TO WORK MY BOY!

Chuck I can say with 110% certainty that no matter what you say it will not change what I am currently working on or what I plan on working on next, but thanks for your requests
Around here when anyone mentions a controller that begins with 'T' we all run and hide.
