Problems on 1.5.0 update(MS3 pre-1.5.1 beta 1 firmware released)

[emanuelgancedo]

Hi, i used ms3 1.4.1 release in a VW 20v Turbo. Today update to 1.5.0 release. With this version the car is not good, i cant accelerate and car is as if it would be placed in 3 cylinders, its like ignition or fuel fail, only update firmware, and active wastegate dome.
Put 1.4.1 again, and car run perfectly.
Sorry for my english.
I used ms3x, channel ABCD for 4 injectors #250cm3 and channel EFGH 4 injector #2500cm3.
Thanks!

I split this topic as it has nothing to do with the pre-1.5.1 beta 1 firmware.

Attach MSQ/MSL.

Ok James, sorry. Its a bug of 1.5.0 or someting error in my config?? Only update the firm, all config is the same.

[emanuelgancedo]

Can somebody help me? Need more information?
Thanks

Hi, i attach MSQ and Log.
In falla.jpg picture, the car not pass 129 kpa, and AFR ir totally erratic.
In andabien.jpg boost 170 kpa and AFR is stable and car run GREAT!!
Only differences between two drag races is the firmware and wastegate dome control.

With the simple fact of updating the firmware, runing slowly the car is wrong, as it cuts the fuel for small moments randmonly.

Other bug i detect in 1.5.0 when set wastegate dome, in simple Metod, and later i test output valves in OUTPUST TEST MODE I/O , dont work correctly. Later set in PID control, and go to OUTPUST TEST MODE I/O work fine the test!!
OK msq run car OK
Wrong msq car not run ok.

Sorry for my english, and thanks!!

Attach msq car faill

[emanuelgancedo]

Hi, i find the problem. When i set dome control in cloosed-loop algoritm, the car fails, driving slowly without the need for turbo pressure feels that it is wrong, as the fuel is cut or ignited, if you set the dome control in open loop, run great car.
I dont know what happening.

I found that upgrading from 1.4 to 1.5 required quite some work with the Engine States. Maybe you have something there?

[emanuelgancedo]

Hi, yes.. actually i have this config.
I dont now what happening, the car only fail when i set closed loop algoritm in boost control setting (using wastegate dome metod)

Attach video with the issue.

[emanuelgancedo]

That listening effect, under boost conditions it becomes impossible to accelerate

[jsmcortina]

It is difficult to help without a datalog. (MSL)

I looked at your MSQs. Have you actually got a dome control system? i.e. CO2 cylinder and twin solenoids etc.?

Your MSQ says that Sensor 1 is "Temp Oil" but your dome control settings are using that to monitor dome pressure?

Have you used the dome control Test Mode to confirm system operation? This is important.

Sorry james, I did so many tests that I mixed the msq. Test all versions of firmware as of 1.5.0 and all do the same. I attached the MSQ that I used when I made the video. It's the last version that you got now beta3.
Test the dome system with the engine turned off and it works fine.

If you need me to do any tests, tell me and I'll do it.

Thanks!

Attach Datalog, At 17.691 seconds, switch to open loop config dome.

Don't change modes while running.

James

[jsmcortina]

Please answer these:
1. Do you have the two dome solenoids plumbed in?
2. Does Dome Test Mode work?

Your target tables are 100kPa - nothing is going to happen because you aren't targetting any boost.
The datalog you posted is of the engine idling, again - nothing is going to happen because the engine isn't supposed to be making boost.

James

[emanuelgancedo]

Yes james, everything is connected, and in test mode when I put a target works perfectly.
There is no mapping of the boost because when I activate the system and want to go out to test the engine behaves strangely, that is to say, when I try to transit to the track, it is already malfunctioning. As if there were misfiring, as if the fuel would be cut off for short moments. That symptom can be seen in the video.
It is difficult to explain because my English is bad.

[emanuelgancedo]

I did some tests with the oscilloscope. The problem is when I use the ms3x outputs. An erratic pulse is seen on the oscilloscope. When I change the outputs to v3 and connect the oscilloscope to these outputs, a clean periodical signal is seen.
