On power on the fuel pump relay is energised. If no tach pulse is received within 2.5 seconds it then turns off.

I would suggest that hooking up the laptop is the very minimum you should do. Without that you have no idea whether the Megasquirt is connected correctly, getting signals etc. etc.

I don't think you are getting a tach signal from EDIS into the Megasquirt, it starts on the priming pulse and then dies.
When you connect up the laptop you will see this because there will be no rpm, no cranking, no nothing.

Yes, that's the Fuel pump relay, you know, the relay that's supposed to run your fuel pump. (but is instead powered by your switch)

im working on a diagram and the guy who sold me the kit still hasn't contacted me.

also i ran his fuel & timming maps in my car we have/had basiclly the same set-up. so i never hooked up a laptop to run megatune.
thanks

Oh, Well if you would, it will help for troubleshooting purposes, to hook up the Laptop while you are cranking to see if megatune sees any RPM, Also This is how you get the .MSQ configuration file you should post that i mentioned a while back.

When you connect the laptop to a powered up Megasquirt the first thing it does is download the configuration into itself (Megatune), then you save the .msq and post it here, this makes it easier for us to look at your setup and troubleshoot any possible configuration problems.

i have megasquirt version 2.2
the megatune im running is 2.25

im getting no tach signal in megatune but im getting a tach signal on my cluster. im just running a wire from pin 11 on the edis module to my cluster tach wire.

also when i run megatune i get a pop up that states this.
controller code version does not match signature in megasquirt-I.ini
(see audit.log for where the above file was found.)
expected "0x14"(found in ini file)
recieved "" (from controller)
table corruption may occur this is usally a very serious problem.

You haven't setup Megatune. As it says this IS a serious problem. However it sounds like you don't have any serial comms working at all. (wrong port or incorrect cable perhaps)

See
http://megasquirt.sourceforge.net/extra/setup.html
and the Megamanual for comms testing.

Rab,

Please read the MSnS-extra instructions for setting the correct .ini for the version of firmware in your Megasquirt.

http://megasquirt.sourceforge.net/extra/setup.html

Scroll down to the section that say's "Setting up Megatune"

You will need to run mtCfg.exe and open up the MegaTune225 folder and "activate" to correct MSnS-extra.ini version that corresponds to your firmware.

rab · Post by **rab** » Sat May 13, 2006 3:43 pm

i followed the instrutions and i get this now

also when i run megatune i get a pop up that states this.

(see audit.log for where the above file was found.)

also i can ignor it,(i know it's not right) and on my page with all the gauges rpm,coolant,air intake temp, they all work and read but im still not getting a rpm signal/movment

thanks

OK, you should "Activate" the 25s ini file, or leavit as is i think you should be ok for now, you really should think about upgrading to the latest stable Firmware sometime.

So you crank the engine witrh Megatune running and connected to Megasquirt and no RPM. You have a PIP input problem, either you have a connection problem from/to the module, or a configuration problem with the input circuit of the Megasquirt.

According to the documentation presented Here - http://megasquirt.sourceforge.net/extra ... dware.html The Pip wire from pin 1 of the EDIS module should go directly to pin 24 of the Megasquirt.

You should also have the Megasquirt tach input configured as per the instructions on that same web page. It sounds complicated but it is really easy to do if you follow the instructions for your board one step at a time.

my pip wire from my EDIS moudel (pin 1) goes to my relay board, to the tach spot marked on the relay board.

Is there a way to check if im getting a pip signal to my relay board ?
Also is there a way to check if im getting a pip signal from the relay board to the ms?

Also im probably the worst person on this forum when it comes to computers and computer knoledge.

what do you mean by upgrating to stable firmware? and were do i find it.

you can check with an ohm meter, end to end from pin 1 one the EDIS connector, to pin 24 of the MegaSquirt Connector, also with the EDIS connected and the power turned on you should get ~10.5 volts to the Megasquirt on Pin 24.

Also im probably the worst person on this forum when it comes to computers and computer knoledge.
Oh? that's nice, that really gives me a warm fuzzy. At least there's a good chance you will learn something new here by the time you're through.

What I mean't is that since the controller has 25s and you are using the 25l .ini, since there is no difference in the structure between the two you should be ok for now, but later when you get it running you should upgrade to the latest and greatest stable version. 029q2 is the latest 029 release and supercedes 024s as the official stable code. This code can be found here - http://sourceforge.net/project/shownote ... p_id=71778

The instructions for installing it are here - http://megasquirt.sourceforge.net/extra/setup.html

BUT now you are getting ahead of yourself. You need to fix the input trigger (PIP) first.

If you do have continuity from the EDIS module to the Megasquirt, and your Megasquirt is configured properly, Generally your EDIS should still work in limp mode if you disconnect the Spout wire. The EDIS module should run the engine even if it's not connected to the Megasquirt, Do the spark plugs fire when you turn over the engine? I think you have a wiring problem with the EDIS module if your Megasquirt is known to work in another car with EDIS.

Sometimes it helps to get a second set of eyes on your wiring, can you get a buddy to confirm your wiring?

EDIS 4 wiring -

rab · Post by **rab** » Tue May 16, 2006 6:39 pm

well i went to check the wires and when i checked the plug for the MS from the relay box,, there were 2 loose wires just hanging out of the harness.

the wires must have came loose from opening my glove box , that's were i mounted the ms box and my relay box is mounted were my stock ecu use to be mounted.

the harness between the relay box and my ms box was homemade, I found this place that sells them,, here is a link
http://www.diyautotune.com/catalog/mega ... -p-47.html

what do you think of there quality???
this will work for MS with EDIS right????
also do you know of anyone else that sell's pre made harnesses like this one.
also were can i get a wiring diagram for the harness from relay box to ms box??

thanks

It's good you found a problem, thats a load off my mind.

DIYAutotune is first rate, you can also get relay harnessess from SparkandFuel.com and nice cables from RS motorsports. Look in the Products a services forum. http://www.msefi.com/viewforum.php?f=77

The wiring from the Megasquirt to the Relay board is 1-1 as shown on the Page "How to Make a relay board cable". http://www.bgsoflex.com/mspower/relay-cable.html

well i got my relay harness from DIYAutotune and im having the same problem still.
Im still not sure which one is pin 24 so i can ohm test it??
thanks ryan

rab · Post by **rab** » Tue May 23, 2006 6:38 pm

o.k. i see that there is numbers on my relay to ms harness ends.
how should i go about probing pin 1 on the EDIS?
cut away on the wire from pin 1 or can i just probe inside the connector to
pin 1?
thanks ryan

Post by **jsmcortina** » Wed May 24, 2006 2:05 am

A common approach is to use a large (sewing) needle shoved down the back of the connector if measuring voltages while running. But in this case, unplug the EDIS module first and probe from the front.

rab · Post by **rab** » Thu May 25, 2006 5:15 pm

im not getting a reading at all when i ohm test from pin 1 on the EDIS moduel to pin 24 on my harness connection to the MS box.
what kind of ohm reading should i get?

im not sure if im getting a a nice connection for the probing so,
if i probe from pin 1 to pin 1 (on the EDIS moduel) what kinda of ohm reading should i get.

thanks

When using an ohm meter you should use the lowest ohms setting on a non autoranging meter, then touch the two leads together to check the zero on the meter, then when you read from pin to pin you should get less than .1 ohms per foot. 10.5 ohms on a 4ft cable is not very good.

rab · Post by **rab** » Sun May 28, 2006 5:48 pm

well i was getting a bad/sparatic ohm reading from pin 1 on the edis module to my relay box tach. i went and made a new wire and it runs!!!!!!!!!
problem fixed, for now and every i hope.

thanks to megascott and everyone else who helped me.
also i learned a little about wire testing and other stuff.
this forum is great.
thanks agian ryan
