Re: BMW S62B50
The main outputs are hardware PWM and have a set number of available pins that is governed by the processor design. The recently added secondary outputs are software PWM and can use a wider range of pins.

Re: BMW S62B50
I rewired it and a setting problem pop-up.
Saying PWM group: nitrous 1/2 and inj1/2 must have the same frequency.
James, could you suggest me how I can rewired it to solve this problem?
How I have outputs wired:
- Idle valve: Injbank 1 and 2 (100hz)
- Vanos pressure accumulator: Fidle (100hz)
- VAnos valves: Nit1/2, tacho, IAC1/2, VVT, Boost, Idle (20hz)
MS: alpha 9
I attached the MSQ file to help.

Re: BMW S62B50
Solved, I figured how I need to connected.
The cam fault is on, I don't have any value on VVT2.
Some tips to solve it? The composite log or logcrank&cam would help?
MSQ File:
https://www.dropbox.com/s/bdriitjdyd7vd ... 0.msq?dl=0
EDIT: I forget to do a log file and after that I had a problem with fuel pump "fuse".
I notice that vvt 1 3 and 4 had some fluctuation around some value like 9 deg, but vvt 2 was always 0. I tried to do the vvt test mode on all vvt but didn't work.
Any suggestion?

Are you sure VVT2 sensor isn't damage? You have tested it?

Re: BMW S62B50
I didn't had time to test. There is something like composite logger but for all cams sensor to see the signal that Ms see?

Re: BMW S62B50
The firmware includes an "engine logger" that records all cams. You need the registered version of TunerStudio to be able to use it.

How I use it? Just do it or I need to do something like in logcrank&cam on ignition menu ?

Re: BMW S62B50
I know here it is, my question is how I use it? Do I use it with the engine running or do I need to change the spark mode to "logcrank&cam" like I need to get a detailed composite log?mr2.3sge wrote:I think this can help you my friend ;)

Re: BMW S62B50
Here is the engine log.
https://www.dropbox.com/s/jgtavug1qhk8l ... 7.csv?dl=0
VVT1 = exhaust bank 1 (CAMin)
VVT2 = intake Bank1 (JS10)
VVT3 = intake bank2 (PT4)
VVT4 = exhaust bank 2 (Datalog in)
I don't have any signal on the log on VVt1 and VVT4. I measured on the input of my custom conditioner circuit with multimeter (frequency) and I confirm that the signal is reaching the circuit.
My guess is since I wired the input pin of ms3x circuit of camin and datalog in to cpu pin, so I can use my own circuit, something there is messing up with the signal.

Re: BMW S62B50
VVT is disabled in the MSQ you attached ?
Please post the exact MSQ you are using.

I checked and this has VVT enable.

Re: BMW S62B50
Generally please ATTACH right here instead of posting offsite links.
I persisted with the MSQ you attached yesterday and enabled VVT and disabled the generic PWM outputs. I don't have a full test setup to confirm all inputs, but with that MSQ and applying some kind of signal I _do_ get an input on PT2 and PT6. That points me towards an electrical problem at your end.

I replicate the pt4 ms3x circuit for all four cam sensors and I placed I wire to bypass cam in circuit, data log in and pt4 circuit, on ms3x. I think these circuit are still affecting the signal, do you have an easy way to totally disabled the ms3x circuit?

Re: BMW S62B50
Now I have signal in all cams.
Two things I think is not right:
Cam flag still active.
VVT4 duty is changing, while others are constant.

I know that appears to be noise noise at vvt 1 and vvt 4 too.

Re: BMW S62B50
I found the problem it is in vvt4 signal.
The vvt4 circuit is connected to datalog in, but I removed all its componnents and done a bypass. You can see it on the photos.
I attach the some photo of what I have done.
The tests that I did, measure resistance:
- between ground and cam signal on vvt1, vvt2, vvt3 after conditioner circuit: 3,27kohm
- between ground and cam signal on vvt4 after conditioner circuit: 340ohm
- between ground and cam signal on vvt4 with disconnected: 340ohm
- between ground and cam signal on ms3x vvt4 with disconnected: 340ohm
- between ground and cam signal on ms3x vvt4 with disconnected and ms3x db37 pin disconnected: 440ohm
- between ground and cam signal on ms3x vvt4 with disconnected and main db37 and ms3x db37 plug disconnected: 540ohm
- between ground and cam signal on ms3x vvt4 with disconnected and all plug plugs disconnected (internal and external): infinite

Re: BMW S62B50
Are the cam sensors VR or Hall effect?
Can you post a schematic of your cam circuits?

Re: BMW S62B50
They are all hall sensors.
They have a pull up resistor 2.2k ohm to 12v. And it uses the same circuit of pt4 ms3x circuit ( 1k ohm resistor, and 2 diodes) . All cams sensor uses their own circuit and they are all the same. Now I on the phone, later I will do the schematic.
