Troubleshooting WB Projects' E Turbo

You're being quite clear - no worries. But it is very puzzling. I'm really curious to find out what's going on. You might be right about your low voltage under load guess. Maybe just try adding more cells to your pack? You'd still have voltage drop, but my understanding is running an ESC too far under voltage can be hard on it too. And you have plenty of headroom voltage-wise with the motor, no? I'd also think about adding a capacitor bank just to smooth out those spikes. They can cause failure too.
 
I have watched your last video so many times.. It's still think it's loosing sync.
1) I would drastically increase "Delaytime" in the Arduino Nano code and see if that stops it (What do you have it set to now ? my original file had 2000ms (2 seconds) but Alex changed it to 400ms if you are using 400ms try the 2000ms.. If it is 2000 try 4000

2) I would find out what motor timing the ESC is set to and drastically increase it.

Motor timming is 10° I think and im at 2sec of ramp up for the ESC. If I go higer, I will not have the time to spool the turbo 😂
 
BTW this is the video where we thought I loose sinc. The other is surge for surehttps://youtube.com/shorts/nTGWVPQJA_8?feature=share
 
Set the timing to 25 and the Delaytime to 3 seconds.. try that for a test to see what impact that has on the problem you can always change it back...
when you have sync problems increasing timing is the number one thing to try.

On a side note in the NEW code the delay time is handled in a far more complex manner. When changing between gears it wont RE apply all of the Delaytime assuming it takes less that 6 seconds to change gears. So response will be much better after shifting.
 
I will keep an eye on you code for the response after shifting. I will wait untill Marek response to me because it's on specifique conditions that the ESC make this weird noise. So I don't think its timming issue. In everyday use I will never be in that situation. Anyway I need to upgrade the battery pack so if it's continue to do this I will change the timming
 
does your car have some kind of VVT?

you might be running different CFMs of air through the intake at the same RPM (but different gear means different "load request")

you might be running against a wall with the eMotor?
 
even logging your boost might not show comparable results ... since your cannot replicate the same eMotor/impeller rpm!
 
one more thing : modern EFI cars with Drive By Wire do implement some smart throttle valve control! Your pedal position is NOT linearly/directly connected to your actual throttle valve position (TPS).

(Thats why I intend to get TPS / LOD in addition to RPM through OBD2 data traffic!)
 
I don't think I have variable timming but the load change for sure. But I thought it would have been the opposite.

Any progress on the sync issue? I'm still undecided on which way to go...

Yeah sorry for no updates. I've talk with Marek and it sound like RPM limitation. He still don't think it's a sync issue. We are pretty sure it's a battery issue. I will try with a new battery but not now. It's going to be in couple months. Like we discuss discuss here, it happen ONLY at 2nd gear with hight engine RPM.
