Right guys dug this one back up
When I initially contacted Omex I got no responce and I was in abit of a rush so I continued to use my 2 wire bosch PWM idle valve this valve has now had it and wont work below 80% duty which we found out when mapping for a new inlet, so im back on to using the standard valve as my new inlet manifold is designed to use it.
It was setup with alot of ignition retard to get it to idle with the dead valve
I contacted Omex again asking about running the stepper motor on a 710 which i belive is very similar to the EM36?
They said it was no problem but I had to buy the 710 stepper motor adaptor which I assume is the duel H bridge setup that we previously talked about?
Heres the instructions
Here is the valve I am using
Now I think the instructions are abit vauge
I have decided to use FUEL3 and FUEL4 as my idle outputs
This is what i have changed on the calibration
I have turned off FUEL 4 as PWM
I have turnned off pwm idle not stepper
I have unselected idle PWM1 and 2 out to none
I have selected Idle1 stepper out to Fuel3
I have selected Idle2 stepper out to Fuel4
This has also changed the out idle1 and out idle2 further down the options list as expected
Now i have wired everything up temp as of the bottom diagram the first thing i have noticed is with the ignition off the box outputs a 12v feed all the time so this needs to be in to an ignition live rather that a terminal 30 but thats an easy fix
On my valve I have tested the pins and A and D are linked together and measure 50 ohms and B and C are linked together
again measure 50 so thats how I have wired it but wired up like this the valve just moved in and out very slightly no matter what the coolant duty cycle is set to, I have tried changing the inputs into the box from fuel 3 and 4 but this made no difference i also tried changing the polaraty through the valve windings but still no difference
I belive mine is a marrelli type valve as we mensioned previously and on the top of the instructions that is wired differently so I have tried to wire it up as shown now this time the valve moves out for about 10 secondsand stops untill you change the duty cycle then it moves again for 10 seconds, I then noticed if you touch the end of the valve it stops moving out and reverses but has not relation to the duty cycle.
I though it might be doing this as its not bolted in its housing so there is no stop, so I bolted it in to the housing but apears to be the same
Now do you think this is an obvious setting I have missed as im pritty stupid or the wiring or both?
I have attached the pwm calibration and the changes I have made
Hopefully it is somthing easy lol
I spoke to some one who has mapped a car with this valve on a different ecu and they said the responce rate sould be 102ms and the engine should idle at bout 40% duty cycle maybe 30% when up to temp
Thanks
