Dangit.. Steig posted 9 minutes before I did, while I was still typing. :D Same info though. Here's that older EGT thread. http://www.autosportlabs.org/viewtopic.php?t=4518 This was for the same board, but I totally spaced on the offset feature at that time. So all my numbers need to have 1.25V adde...

There are redundant EGT probes at this point. One is connected to the RCP and the other is connected to a GlowShift EGT gauge. I don't have a way to validate the readings of either one unfortunately. Ideally you'd be able to put a voltmeter on the output of the blue board and see how quickly the vo...

Looks like us old MK1 people are limited to 10 channels, while MK2 are 30 channels. Search the source -

Re: Can-X Module Wiring

I have a Can-X module for a Mk1 RCP, and was looking at connecting it to my test rig CAN bus. I looked on the website and can see that the pins on the actual RCP socket run from 1 to 8 (left to right), and can see that I need to connect pins 2 and 3 to my CAN Bus, however I'm not sure of the orient...

Ahh, right.. Modern (MK2) people use MicroSD without an adapter. My MK1 is using a leftover 32MB SD card that has a slide switch on the side.

Stupid question (but it's happened to me) - Does your SD card have a write-protect slide switch that maybe got caught on the slot/front panel as you put the card back in, sliding it to the "protect" position? I forget if the firmware flags a write-protected state by blinking the red LED on the front...

Fixed my MK1 with 2.8.4! My last race event of the season was Sunday, and before each run I'd push the button, get the red light, then a second or two later the red would go out and it'd start logging. Pulling logfiles later, I could see every other file was 0 bytes (failed attempt with red light) t...

Shouldn't. The thermocouple chip has a strong drive output, compared to a resistor-type sensor like a coolant temp sensor. Just wire the 5V VRef and common from RCP over to the new board, and the 4 output voltages to your four analog channels.

I updated my MS2v3 to the 3.4 firmware. Now I have reached a point where I want to actually hook into the RCP2 and realized I don't know where to start. From my understanding, the MS has a CAN-L and CAN-H wire. Not sure how that works in relation to CANbus and a RJ-45 connector. On our Megasquirt 3...

You can also change the log level to limit how much stuff you see. I don't know the default setting, or what I've got mine set to right now...
EMERG = 0,
ALERT = 1,
CRIT = 2,
ERR = 3,
WARNING = 4,
NOTICE = 5,
INFO = 6,
DEBUG = 7,

Did the command / help menu come up when you hit Enter? That'll confirm the terminal session is working properly. The command parser also doesn't understand backspaces, so if you make a typo in a command (like 'vieLog' instead of 'viewLog') you have to retype it, can't backspace and fix even though ...

Use device manager to see what COM port the RCP appears on.. I use PuTTY as my terminal program (also good for telnet/ssh work) http://www.chiark.greenend.org.uk/~sgta ... nload.html then just tell it serial port, set baud at 115200, and it should work.

You can hook up a USB cable to your PC and run a terminal program on the serial port (115200 baud). Hit enter to get a menu of commands; type viewLog to get a running scrolling log of whatever's happening in your script. Here's some of my capture of the CAN dump script, listening to Megasquirt broad...

Lua memory on mk1?

How large a script can a MK1 RCP handle? I was getting crashes/restarts all night trying to get my CANx running with the example Megasquirt script. Eventually thinned it down to about 1250 bytes (removing comments etc) and it works, but I'm down to only two variables. Has anyone else run into memory...
