when my edis is pluged in the #9 pin is grounded even though the wire
is just loose / not connected to a ground. is this right or is there a problem.
thanks

It depends on whether you have EDIS4, EDIS6 or EDIS8. On the first two, pin 9 IS ground.

See http://megasquirt.sourceforge.net/extra ... dware.html

i have edis 4 and i know that the #9 pin is suppose to be grounded.
with my edis pulged into the module i have the #9 pin wire just hanging there unconnected to anything!!!! and its giving me a ground signal is this right.
is it(#9 pin) supposed to give me a ground signal even thought its not connected to anything.
thanks

How and why are you measuring this?

rab · Post by **rab** » Sun Apr 23, 2006 3:38 pm

im checking it with a old fan i have, and it turns the fan on with the module pluged in.
im checking it cause my car will start and not keep running, i explain the porblem im having better in this post http://www.msefi.com/viewtopic.php?t=18188.

i was wiggleing the #9 pin when it was grounded last night and it worked and now today it's not working.
thanks

Why don't you just ground pin 9 and get it over with, that is the high current ground of the module. The ground from pin 9 you are reading now are from the sheilds from either pin 7 or pin 4. I would say that unhooking pin 9 from ground and hooking up a fan to it would not be good for the module.

Are you powering the module from a source that has continuous power with the key in the "on" and "start" position?

i think my problem is that the #9 ground, some times my car runs and sometimes it won't. last year the problem was the #9 ground acting up.
now i build a nice ground set-up so all my grounds are located in one spot, and i have a problem again. prevouslly to doing the new ground setup this year it ran fine.

the only reason i was running a old fan off it was to see if i was getting a good ground. a form of diagnosing the problem.

all my power going into the ms is on a toggle switch ran directly to the battery both switched and constant power( it worked last year just fine that way , its temp. untill i get all the bugs out).

here is my other post to give you a idea of whats happeing.

well i added some bigger and better grounds to my car .
now the thing will not run.
i checked all the ground and there are fine.(i checked them with a old fan to see in the fan would turn on and it did)

o.k. i have my ignition and fuel pump on a toggle switch ( it ran like this last year, it temp until i get all the bugs out)
when i turn the switch my light for the injectors on my realy board blinks. but when i go to start it, it does not blink (when it ran it would blink, and the acc. back light would blink when i it the throttle.) now nothing blinks

im getting spark and feul, when i turn the switch on and off linke 5 times and
the injector light blinks each time i turn it on, it will run for a second or two but thats it.
last year once it started up the injector light would consantly blink,

can someone tell me were to start to figue this out.

When you say "i added bigger grounds" does that mean you removed small wires and put in bigger wires on the DB37? After you did this did you ohm it out to check your work, can you get someone else to double check your work? Sometimes a second set of eyes helps.

It would not hurt to invest in a simple Ohm meter, you can get cheap ones from Radio Shack, or Harbor Frieght that should work better than a Fan.

by better grounds i mean this.

i went a bought 2 stinger, 3 port distrubution blocks (bass) 4gauge ports
then i bought 1 stinger d.b. 4 small ports 16gauge and 1 big port 4gauge
all of these distrubtion blocks are connected to geather useing a 4 gauge wire and on the end of the sequence of 3 disrubution blocks its grounded to the frame,
it looks something like this -----> ---0-0-0---

here is a link to what the 3 port d.b. look like http://www.darvex.com/miva/merchant.mvc ... ct_Count=1
i then went a used 4 gauge wire and ran a ground to my alternator mounting bolt,head,tranz and some other spots.

i did not do anything with the db37 or anything in the ms box.

i will try to OHM test them tomorrow.
thanks for all the help so far.

rab · Post by **rab** » Tue Apr 25, 2006 6:42 pm

all my power for igntion and fuel are on this toggle im talking about.
o.k. if i turn my toggle switch on then my injector
light on my ms box blinks once.
well if i turn this toggle on like 20 times the car will run for like
3 to 4 seconds.
it just seems to me that the injectors are not shotting/getting power at all time?
when it ran the ms box would blink (injector light) constantly after i cranked the car now it don't
could this be the problem ?
thanks

well im getting power at my injectors(test with a light tester) on the postive side of the injector plug, with the toggle on.
also i ohmed tested the grounds and im getting 0.1 is this good.
(tested with a bluepoint multi-meter)
can anyone help.

MegaScott · Post by **MegaScott** » Wed May 03, 2006 6:02 pm

Rab,

All this is puzzling to me why you would do all that, normally when you toggle the power to the EDIS you may get a coil to fire and when the Megasquirt turns on it may fire the injectors a little, all this could cause your engine to run almost as a consequence of toggling the switch.

I've got an idea. Only turn the switch on just before you crank the engine and see what it does. Forget about flipping the toggle a whole bunch of times you aren't proving anything by doing that.

Now send us a copy of your .MSQ, sit down and make up a little diagram of how you have the engine wired up and see if you can post that too. Oh, please tell us what version hardware, firmware, and Megatune you have.

Thanks!

megascott i will try to figue out what version i have.
megascott don't you own a escort with ms conversion?

o.k. im running jacob russell's old megasquirt on my escort gt with a bpt swap big t3/t4 turbo exe.

if your on FEOA (escort forums) you might remember him and also he was from WA.( and knew the Corksport guys)

I don't remember what version i have im going to try to contact jacob but he sold his escort and moved to Hawaii.

here is a link to his old web page

That was a newer 97 split port EEC-V (not MECS), I sold that car.

I remember Jacob, his old car is this car you have? or just the Megasquirt?

I don't have enough time to post to 8 different forums, so I mostly hang here.

Just post what you have, we can work it out.

rab · Post by **rab** » Wed May 03, 2006 6:56 pm

just his megasquirt system

Post by **jsmcortina** » Thu May 04, 2006 5:17 am

The firmware version shows at the top of the Megatune screen. It sounds to me like you aren't getting a tach signal into Megasquirt. What does the Megatune screen show when you crank the engine ?

Please post the information Scott asked for or we aren't able to offer any more help.

James

im trying to contact jacob about what version it is.
also i have a relay board , that were im toggling my power too.
for diagrams what would you like or are looking for?
im working on it, thanks for all the help so far.
thanks ryan

The way it works here is you tell us what you did, and supply the information, then we analyze the information you provide and come up with possible solutions. The better you are at describing the problem, and the more information we have, the easier we can do this.

rab · Post by **rab** » Thu May 11, 2006 1:47 pm

well on my relay box i have 2 relays and 1 of them will shut off after about a 2 or 3 seconds after turning my power on , is that suppose to happen?

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
