James, i get strange bug on 3.4.2 with sequential mod and using camshaft sensor.
Later i post my msq.

For example, we have 4cyl, 4 inj, 4 cop. crank 60-2 and cam poll level. All fine, but when we use autotune via TS or push burn button - get many lost syncs untill release clutch or throttle. Reflash didnt helped. But sometimes can help.

Didnt tested yet. Only 3.4.2

Many sync errors when use autotune. Or if you just make some changes and press BURN i get many errors untill release clutch pedal and rpm down to idle.

Hello James,

i have a question according to the boost control.

Initial situation i have boost closed loop active with basic tuning mode.

So when the map reach the target - delta region boost ctl starts working.
When we are in closed loop for the first ms loop i thinkt there is something wrong with the calculation of the duty.

Within the first loop error and last error is set to the same value. Therefore Kp is 0.
Ki is something arround 5500.
Kd is something arround 134277.
So because of this values the setpoint is negative an nailed to the min duty.

Can you have a look into this please?
Correct me if i'm wrong.

I checked the code and nothing has really changed in boost_ctl for about three years, so I don't see how this can be specific to this beta.

Oh, so then it's not only specific to this beta, its a global thing.

I think it's not important if it's thgis beta or all versions. When they have all the same code you can check in any off them.

I will figure out why always when closed loop boost starts there is a spyke in the boost duty to the min allowed valve value.

It does matter for developers to know if this is a new issue or a long-standing one - otherwise we go looking for recent changes rather than the code in general.
