Yes with everything plugged in except the ecu.

by **TRD_ZERO** » Thu Jan 28, 2010 6:41 pm

Just wanna add i when plugged into the pc and start cranking i get a little box pop up saying "map limit reached". What the hell does that mean? could that be contributing to the issue?

Sorry matt wont be able to test it out today as i have to go out.

map limip reached means that the manifold pressure is out of the range that it is set for, but it shouldnt be doing that. what map sensor you got? the file i sent you was for my ecu which had a 5bar map sensor fitted.

by **TRD_ZERO** » Thu Jan 28, 2010 7:11 pm

I think its just got the factory map sensor 2bar one

by **matt dunn** » Thu Jan 28, 2010 7:20 pm

WTF?

Link ecu will not run without a link map sensor,
A toyota one is not compatable,
and the G3 should be built in unless it's a Linkplus?

If it is above the map limit, there will be no spark because there is not meant to be, thats how a limit works.

Email me the PCL file to rachmat@xtra.co.nz.

have you run a vacuum line to the link ecu?

by **TRD_ZERO** » Fri Jan 29, 2010 6:48 am

Sorry i meant to say its only got the factory link one which i think is 2bar. Oh shit vaccum line to the link ecu...yeah i havent got one hooked up. Ooops sorry im still learning. Do i just grab any vaccum signal from behind the throttles? Will it still run the map which it tuned for a 5bar link when i only have the factory link mapsensor? Or will i either have to adjust the map or get the a 5bar map installed?

don't know if this would cause these problems, but have you calibrated the map sensor through PClink?

should still fire without a vacuum line connected, it will just run like a bag of crap and probably won't idle at all

I've forgotten to hook up the vac once, the car wouldn't start, but there was still spark!

what does the MAP say the pressure is when you have the link connected with out the engine cranking? should be about 101kPa

The error is map limit activated.

Just tried it and im getting 253kpa with no vacume line.

Doing matts tests now

by **TRD_ZERO** » Fri Jan 29, 2010 5:13 pm

I tried the tests but im getting terrible results trigger 1 (black on dizzy) measures 0.194 kohms
Trigger 2 (red on dizzy) measures 155 ohms
the green unused wire reads 155ohms also

Voltage on trigger one was about 0.38...v
voltage on trigger two fluctuated from almost nothing to just above 1v
tried cranking with green but readings were quite low.

Could that mean trigger one red and trigger two green?

Also found when cranking dwell time goes red and reads 8ms i think. I dnt know what that is but i didnt like the red. Thought i might have to mention it.

That is a problem.

Try turning the map limit to off and see what happens..

by **TRD_ZERO** » Sat Jan 30, 2010 1:37 pm

I saw that option of turning it off but wasnt too sure if i should fiddle with that stuff as im no tuner. Will it be safe turning the map limit off. Im away for the weekend but ill try these things when i get back.

will be to see if it fixes it, as a diagnostic tool.

but if it does fix it and you get spark,
then there is a problem you will need to fix before you run it properly.

by **TRD_ZERO** » Sat Jan 30, 2010 9:30 pm

And what do you gather from the results i got from testing the triggers?

by **matt dunn** » Sat Jan 30, 2010 10:01 pm

Does not really make sence? Something in my memory feels as though the diagram on the link site may be upside down in it wiring......?

Test at the dist itself unplugged.

From the common or earth pin, to the other 3.

Earth to pin 1 should be 155 ohms
Earth to pin 2 should be 155 ohms
Earth to pin 3 should be 155 ohms

If not, try the earth pin being at the other end and re-test.

I'll see If i have a dist I can check as all this is just off the top of my head.

by **matt dunn** » Sat Jan 30, 2010 10:07 pm

Dont have one here but will check tomorrow.

And dont count on the black wire being earth,
as more than 50% chance it's not.

by **matt dunn** » Sun Jan 31, 2010 11:17 pm

OK the diagram on the link site is correct.

Black is the Trig 1 signal and should be around 200 ohms to ground
Green is the trigger 2 signal and should be 155 ohms to ground,
and the white wire is the earth and should be connect to the link earth.

that what i got from testing the dist I have anyway.

by **TRD_ZERO** » Mon Feb 01, 2010 10:17 am

Are you testing from the dist plug? Yeah i looked at the pic and it looked like i had it wrong but then i got my wiring instructions from gasman who said it is the black(1) and red(2) from his working car. Isnt red and green the same signal but just from different positions?? And if that is the case shouldnt i have it the same as gasman since im also using his map?
Ill be going home today to remove the map limmiter. Do you want me to do a data log with the limmiter off or on?

Not firing?? No Spark....Now I have spark!
