Ouch. Here we go again...
I don't know how to fix that.

What ports are you using for ignition and fan control Dan?

I think the issue may be with the WLED and ALED outputs, since the message refers to spark output.  I am not sure how this got crossed up, because we had it working before we tried screwing with the tach signal.
PT6 and PT7 are the ports we are trying to use if I remember correctly, and Jim performed the modification to the board recommended by DIY.  I bought the kit from them.

From DIY Autotune:
"Programmable On/Off Outputs
There are several ports available for on/off outputs. These supply ground to a relay, and may be used to activate cooling fans, variable intake solenoids, and other basic devices that are just on or off. Which outputs to use depends on your plans. WLED and ALED also function as spark outputs, so if you need spark outputs C and D, these are already taken. The MS2/Extra 3.x code can also use PT6 and PT7 for sequential injection output. Plan which outputs you use accordingly.

The IAC, WLED, and ALED outputs can all drive relays directly through FET transistors on the MicroSquirt Module. Simply connect these headers to the appropriate pins on the adapter board.

The other outputs (PT6, PT7, and PA0) require a transistor circuit. Jumper the output port you have selected to the IN pin on RELAY1, RELAY2, or RELAY3, then jumper the the OUT pin on the same relay circuit to the desired pin on the adapter board.

The 12 volt output can take a ground trigger output from IAC, WLED, ALED, or one of the relay circuits, and use it to supply 12 volts to a solenoid or relay. Use this for features like VTEC or GM fuel pumps that are powered from the ECU instead of grounded."

Here is the mod we did, Adding a Relay Circuit:

Beyond the physical circuits this stuff is indistinguishable to me from magic. Sometimes I manage to muddle through but I have no idea how it really works.

But if you have a conflict between the aux outputs and the ignition outputs one or the other needs to be turned off, so maybe it means finding out how to turn off the ignition outputs.

That's just a guess because you still need the SAW signal to run your EDIS.

It seems to make some sense, since it was all working before until we enabled the tach output.

I know we disabled (tried anyway) the tach output before but didn't get it working again until we disabled the aux outputs. So maybe we were not successful in disabling the tach output? (Or some other related spark output that we might have turned on in attempting to get the tach to work?) At this point that seems like the most likely scenario.

You could try disabling anything that looks like it is remotely associated with the ignition system and see if the error goes away.

QuoteThese supply ground to a relay, and may be used to activate cooling fans,

Didn't say anything about turning them back off.  

Right, Carl, but since it goes through the controller which switches the relay and the ignition turns the computer off then it goes all the way around the barn to close the gate.

Point is, we did have it working.

Until we enabled the tach output.

So.... going the long way around the barn to do it, how about reloading the firmware then reloading the tune from scratch? Lots of work I know. Means printing out screen shots of every single configuration page and then using hard copy to put it all back in, creating an entirely new "My Car" project, but it seems to me that would work even if nothing else does.

That's option "D". The error message tells us there is an option "A". If we knew how to do it.

Any luck with the MS forum?

Jim

I posted the msq file to the thread I started when we were messing with it..  Still waiting on a reply.

Hi Dan,

How's the troubleshooting coming along?

I found a similar thread on the msextra forum.  It seems that a there is a known bug in the program that creates the error I am seeing when I try to activate the extra ports.  It causes a conflict with the injector ports.  I have asked if there has been any resolution to that but so far have gotten no response.  I guess I am going to have to just go old-school and put a switched relay on the fans or something so they cut off when I turn off the engine.

Huh. Interesting. I'm assuming we still have the latest firmware loaded, you might want to contact Matt at DIY with a call or email and ask him about that. Could be a more direct route to a solution. If you do, try to give him the reference to where you found it.

Jim

Sounds like you're having fun! Thanks for the update Dan.

Sounds more like MegaPITA.  

I saw somewhere in the UK a company is now selling the subframe to fit this motor in the Wedge
