Re: S54 dual VANOS VVT
Ok, I understand, you use MS3PRO.
Question,
MS3PRO have highside circuit? if yes, you are sure the out is correct?
exhaust vvt1 open solenoid charge oil
exhaust vvt3 open solenoid discharge oil
Intake vvt2 open solenoid charge oil
Intake vvt4 open solenoid discharge oil

Re: S54 dual VANOS VVT
MS3-Pro doesn't have high-side drivers. An external adapter is required.
I already changed the user-interface.

Re: S54 dual VANOS VVT
About this I can give you information about how OEM ecu controljsmcortina wrote:Does the cam _really_ move that much? On all other systems I've seen, there is enough leeway in the signal that the phase can still be identified whether the cam is in the full advance or full retard position.
However, the suggestion to discharge the hydraulics makes good sense also. Do you still have access to the test car? I'm guessing that the customer has taken it away by now.
James
Check the last 10sec. The upper line is the charge valve, and the botton is the discharge.

Yes, the diodes have been switched so we can control with the negative outputs.AbatelliCristian wrote:Ok, I understand, you use MS3PRO.

Re: S54 dual VANOS VVT
ok, do you have tested the output in vvt test mode?
To simplify the test, you can disabled vvt and enabled generic output and make test in order to understand if the outputs work well and to understand the order of the output

Re: S54 dual VANOS VVT
I will reverse the cam inputs and do the generic PWM testing to verify proper operation then move onto the VVT menu again.AbatelliCristian wrote:ok, do you have tested the output in vvt test mode?

Re: S54 dual VANOS VVT
Still can't get this stuff to work. I loaded alpha 9 today and it seems that vvt3 and vvt4 duty do not output.
Also without VT enabled, I don't have a Cam Fault indicator. With VVT It lights right up. I'll post some data as soon as the files get transferred from the laptop.
The factory hall sensors have inverted signals as well, could this be causing an issue since "falling edge" is greyed out in the CAM1 dialog and I cannot chance it?

Re: S54 dual VANOS VVT
You can change it... there's a new-ish setting that allows you to "flip cam polarity."

Re: S54 dual VANOS VVT
Do you have all OK with the exhaust cam? That signal don't seams to be a hall sensor.

Re: S54 dual VANOS VVT
James, is the code S54 code intended for 8-1 on the Cam? If I set it for 7 teeth the exhaust EGT angle goes haywire, if I set for 8 it stays steady but non very controllable, it will stay static until I change the target extreme to one end or the other.
Is the red reference line that goes from top to bottom in the engine log a sync error?

Re: S54 dual VANOS VVT
The code is for 8-1. Insert 8 tooth in the setting.
I see your msq. Decrese frequency solenoid. Use 20hz.

Re: S54 dual VANOS VVT
When it was on 20hz, I couldn't get any changes to happen. I incresed it back to 200hz and the intake cam hit target right after startup.AbatelliCristian wrote:The code is for 8-1. Insert 8 tooth in the setting.

Re: S54 dual VANOS VVT
You have tried to reduce P I ?
can you make composite log?

Re: S54 dual VANOS VVT
I will try to get a composite log in the next day. I need to return to his shop.
I did change the numbers slightly but with the other issues I was just running in circles.
But I don't know why Duty 3 and 4 have no movement, only 1 and 2.
Are you using Alpha 1.4.9 on your engine now?

Re: S54 dual VANOS VVT
I noticed that vvt3 and vvt4 is 0.
But I saw that VANOS intake reaches target. I thought it was an error log.
I was with previous versions because the customer has withdrawn the machine.
I will update it at the first opportunity

Re: S54 dual VANOS VVT
The signal in the exaust sensor is the signal is abnormal.
which circuit uses ms3pro for it? and is equal circuit of the intake?

Yes, I think I had the probe in the CMP- instead of CMP+. I need to revisit that as well.AbatelliCristian wrote:The signal in the exaust sensor is the signal is abnormal.

Re: S54 dual VANOS VVT
Abatelli did you have all VR sensors? Or Crank VR with hall sensors on the cams?

You don't need it here with "Toothed wheel"... just change the second trigger polarity.Mario wrote:The greyed out feature?
