Re: K Line Problem

Thanks.
This is becuase my program (a Atmel AVR M128 microcontroller with
Graphic Display) halts when I accelerate the engine. This produces
noise and I "see" (I have a monitor led on the K Line, so I see each
byte sent and received - very quicky - but it's a nice way of
wathcing the communication), that the ECU sends a byte 3 times with
a large delay before disconecting. That's why I supposed the problem
is noise on the K line. Also, I have tested all the proyect without
the engine on, and the communication works perfectly.

Another question. Is there any way I can get RPM in a faster way
than reading a block of 4 data?
Thanks
Ezequiel

P.D.: If anybody is interesting in sharing info, and schematics,
please send me an e-mail.
