EDIS and Programmable outputs

Postby Kbert » Mon Jan 16, 2017 1:51 pm

I had my MSII running on a GM V6 a couple of years ago and have recently modified it to run with an EDIS module. I am using the Jimstim to test it out.

One of the things I had it doing before and would like to have it do again is electronic cooling fan control. I had this running off of D15.

I completed the Hall sensor circuit and connected JS10 to IGN and I am getting a good RPM input and can see the SAW output using a scope (or changing the spark output to going low and connecting it to an LED on the Jimstim).

With this working I tried to set D15 as a programmable output based on coolant temperature. It worked fine turning an LED on and off on the Jimstim. However, when I powered down and then turned the unit back on I received an error message stating I had conflicts and the megasquirt didn't know how to deal with them. Disabling the LED output and power cycling the board fixed it. I tried it with all the outputs I should have available (LED14, LED15, LED16, JS11(PA0) and FIDLE, I am running a 4 wire IAC motor). The only output that would work when turned off and back on again is FIDLE. Since they work before the power cycle I would think that they should be useable.

Is this something that I have done wrong or is this expected?

Cheers,
Kberg

The error I get states the following:

"Settings Error!

You have a sttings error! on Project
This means there are conflicting settings and the MegaSquirt does not know how to handle them

The following error was reported by the MegaSquirt:
Conflict between spare output ports and spark outputs

Unless directed in the above message, you do not need to reload firmware to fix this problem.

To resolve this you need to correct this error in your settings then powercycle the MegaSquirt"


Since I'm set up for EDIS and I am using JS10 for SAW I shouldn't be using any of the spark outputs, so I am confused.

Nothing to do with your issue, but I did notice that you need to set Dwell Type to Fixed Duty when using EDIS.

When I get a few minutes I will load up your MSQ on my test ECU and try to replicate your issue........

I will fix the dwell settings when Im next at the computer. I appreciate the help!

Well,I'll be dipped!! I loaded your MSQ into a new project and got the same results as you. I then used my own MSQ, set it to EDIS and, again, got the same (config error) result!

Dunno....... Lets see what the guys with the big brains have to say about this..............

Ken

EDIT: Also tried using Basic Trigger, and got same config error........

That doesn't sound like it is behaving as you'd expect. The code is supposed to be reserving JS10 and should be leaving the other outputs free.

No it isn't working as I would expect.

I tried using Basic trigger and then setting up all three LEDs as programmable outputs and it did work for me (msq attached). Setting it back to EDIS causes the config error to return.

Interesting......... I get the conflict error using Basic Trigger mode also.

FWIW..... I would have never noticed this issue if this thread had not caught my attention because I only use Toothed Wheel mode. Regardless, I can't speculate whether this is either a firmware or a TS issue.

So, I have been trying various things to fix this. I rolled the firmware back to 3.3.3 and I still had the error when trying to run EDIS and using D15 as a programmable output. I am at a loss here.

It may well have been broken for a long while. Somewhat odd that nobody has reported it before.

Odd, but possible I suppose.

So is there a specific place I should report it or is it considered reported now?

Thanks for looking at this!

Since James is aware and responded (above) I think you could consider it reported.,,,,,,,,,

So, I have found something I need to try. I was looking over a build thread and the gentleman performing the work has a similar setup. He is using a Toyota V8 with an EDIS8 and came across the same "Settings Configuration Error!" message in regards to spark outputs. His issue got worse when he tried to reflash the firmware. Turns out his problem was his USB to Serial adapter as it worked fine after buying a new one. I am hoping to get a new adapter and try that this weekend.

UPDATE:

I purchased a new USB to RS232 adapter. I uninstalled the old driver and rebooted. I then installed the new driver and rebooted again. I plugged in the adapter and reflashed the firmware. It seemed to take longer than before. I then fired up Tunerstudio and changed the ignition options to EDIS and tried setting LED15 to turn on at 90C. I burned the settings and power cycled the MS. It worked.

I then loaded up my previous project and burned it to the MS. Same problem as before. So I went back to the test project I just created and loaded all those settings again. Again it worked. So I built on that and entered all the settings from my original project and it still works. MSQ attached.

So it looks like my problem is fixed, but I don't know why I had it before and it comes back if I load that project. So I'm deleting it and going with the new one.

Kbert

Changing project doesn't alter the fact that there's a long-standing firmware bug.

True. It just means I managed a way around it. Other than a new adapter I don't know what I did different.

This sounds related to my spare ports issue. Any update on the firmware bug?

After re-reading this thread, it is exactly the same problem I am having with my 1uz EDIS setup. I have been working around it to run the cooling fans without MS control. I posted the msq on the other thread. viewtopic.php?f=122&t=65734&start=20
