Tacho output on JS0

Ilian · Post by **Ilian** » Wed Mar 05, 2008 5:26 am

Hi everybody,

I'm driving with MSI Extra for more then a year. I'm trying to upgrade to MSII Extra Beta 20 and Beta 21. On MSI i'm using the tacho output and it's working fine. When I put on the new processor the engine is working fine but I can't make work the Tacho. Do I need some modifications on the hardware? Switching back to MSI it's working again. I try all the possible outputs and can't make it work.

I had tach output on JS0 (IAC1) working on my car at one point. In the last Beta, Beta21, I couldn't get it to work on JS0. I was like, whatever.. And moved it to JS10 instead. I don't know if it's a bug, or just me. Did you set tach out to be IAC1? Did you try IAC2 as well? I seem to remember them being reversed in MT at some point.

Yes I have try all the possible outputs without successes. Is this a bug or I have to change the output on the board?

It's a bug.

I've had Tacho working without issue on JS11 for a long time now, on previous betas, and B21.

I'm having another issue with JS0, though, perhaps it's related. See this thread:

I can't go into more detail yet, I'll wait till I'm asked.

I'll probably be taking a look at this soon. For now please start up hyperterm with 115200 8 n 1 settings, and get the config error string. That'll help us find where the problem is, or if it is even a problem.

For the tacho out to work on JS0, you need to set it to output to "IAC2"

I just tested that configuration now, and it seems to work.
