Megasquirt Support Forum (MSEXTRA)

I get this:

"Empty read, No Data Received from Controller"


MSII V3.0 with a new msextra firmware. The rest works perfectly, I can get signal from MAP, TPS, thermistors (RPM on the way)...
It's really hard to sync RPM without that, I know I could do that manually with an oscilloscope but mine is quite slow using both channels.

Which can be the problem? Firmware? computer? cable? ms2 daughterboard?


Thanks!

Are you following the steps shown in the manual? http://www.msextra.com/doc/pdf/html/Meg ... 5-337.html

If it is getting empty reads, the MS may not be seeing any signal for the crank. Pots?

Thanks, I solved this when I finally synchronized RPM

I was seeing that when I was chasing sync issues. Sometimes I would get nothing.

I still can't seen to get a MAP log. The pages never start piling up.

In the composite I only get RPM, CAM and sync loss. No TPS, no MAP, no O2...

idk

A Composite log is a little funny to read. Post yours here.

Here is one off my car.

That's correct.

If you want a normal datalog, then go to Datalogging -> Start Datalogging
