To others that might be reading this.

I sent the uS to Matt and he diagnosed it as an internal CPU fault where it was stuck in bootloader mode.

The Board was replaced under warranty with a V2 mainboard. Now I have no problems.

Big thankyou to Matt and the Folks at DIY autotune for excellent ...

Ok, I bought it from DIY Autotune! in April/May 2008

What do you think of the chances / costs of repair or should I be looking at a replacement?

Hi Matt,

No I can't connect or load anything with the bootloader not grounded

Ok after some fiddling and using another desktop computer with a built in serial port I have confirmed that:

- With the bootloader connected I can download and verifiy code no problems, I tried a few different versions, all went in ok.
If with the bootloader connected I ask to read the signiture I ...

Hi,

I have been having trouble connecting to the microsquirt V1 that I have.
2 years ago I used it on a motorbike (since sold) and it was working fine when I removed it. Stored it in a dry box since then. Now powering it up on the bench I get strange connection issues.

I am using a HP laptop with ...

HI,

I want to hook up my EGT sensor. It is a thermocouple with a converter that output's a voltage. I just want to read that voltage in to uS using the spare ADC input. How do I read the Spare ADC? port?

I'm not sure how feasable ION sensing would be on a platform like megasquirt as that could be even more engine specific.
I read more on the subject of conventional knock sensing after posting the message and it appears that the way that alot of the knock sensor detection algorithums work is ...

Hi,

I am looking to try out the knock sensing algorithum on my motorbike. However the current settings only allow for <6000 RPM in the knock threshold table. And < 10000 RPM in the settings menu.

Can this be reset to something higher (15000 RPM?) My bike revs to 13500 RPM. Searching on the web I ...

Ok,

So if I get this right you have changed from dual tach inputs to a 8-1 tooth wheel.

So you only now have a SINGLE VR input. Disconnect the 2nd VR sensor.
You need to set to single crank wheel and pick the VR circuit that gives you the smallest -ve trigger offset. Otherwise use delay teeth to ...

Ok, we are looking good!

I tried 4 delay teeth first but this required an offset of +10deg. It looked ok but to be safe I used 5 delay teeth and -35deg.

Dwell on both cylinders is correct (and the same within 0.5ms) all the way to 13000Rpm.

I took it for a test ride and it felt good, the same as ...
