are you using the ms2 downloader to burn the firmware to your MS? Some of us have had no luck with that and gotten the same error over and over.
I now do this method:
Start EasyTherm program
You will see it has 6 boxes to fill in for each sensor.
There is also a "Biased Resistor" box, ensure thats at "2490" for standalone or whatever you determine for parallel install.
Fill in your sensor info into the chart, ensure you select Farenheit or Celcius.
Next select: "Write inc and s19 files"
the display should read "OUTPUT DONE..."
This has generated 3 *.inc files inside the EasyTherm directory:
airdenfactor.inc - Thats for the inlet Air Temp sensor
matfactor.inc - Thats also for the Air temp
thermfactor.inc - this is for the coolant temp sensor
Find these 3 files in c:easytherm/ directory and copy all 3 of them.
Paste the 3 inc. files to the "mtCfg" folder in your car directory
Then paste them in the "src" folder in your car directory
Next double click on the "compile.bat" file, it will bring up a box which will generate an S19 file for you, it will say OK at the end. As long as it says Sucessfully Assembled - OK, we can now copy the newly generated "msns-extra.s19" file (this file is about 76KB, dont confuse it with the msns-extra.asm file which is 447KB. Copy the msns-extra.s19 and paste it into the dir up one, (your car folder). It will over write the one thats in there.
Disconnect your coils/ignitor
Power up the MS ECU, dont remove the lid, theres no need to with this method.
Now double click on the "download-firmware.bat" file,
Select your Comm port (e.g. 1) then select "N"
It will count up to 1730 or so
Then your MS will run again.
BURN A GOOD MSQ TO YOUR MEGASQUIRT!!!!
Now it is safe to plug the spark coils back into the MS ECU!!!!!!
