Re: Custom board base on Proteus Software trouble

I believe there are pin compatible stm32 f429 vg that will allow you to use the official firmware. It might be worth doing a chip swap. Proteus is intended to work with the larger ram on the 429 VG chips due to the number of features on the proteus. yes, all 144 pin f407/427/429/f767/h743 are pin c...

Re: Proteus .04 RPM Spiking, Trigger Error?

Test #1: Set "operation mode" to "4 stroke without crank sensor", re-check trigger offset with timing light. Set cam inputs to NONE. Set spark mode to wasted spark if not already. Take a log. Does the blip still happen? Test #2: Change nothing else, but add the cam input as it's ...

Re: Proteus .04 RPM Spiking, Trigger Error?

Right now I do not have an explanation. Let's start by updating project .ini and fixing your trigger setup. I bet issue would stay but maybe it would not? vvt position ~= double his trigger offset, and he's somehow in "4 stroke cam" mode and that works? Double his trigger offset smells fu...

Re: Proteus .04 ETB Idle Settings/Issuestuner

It looks like most of your problem is a lazy electronic throttle: image.png (the green and red traces should track almost exactly: one is target position, the other is actual position) I remember you recently changed the ETB PWM frequency. That probably means you need to re-run auto PID tuning for t...

Re: ETB Disable when throttle at 100% for >3 seconds

Immediately after this happens, please CAREFULLY touch the ETB driver chip. It might be very hot (150C - no, I'm not kidding). If it is very hot, there are some things we can try.

Re: BMW M70 in 8 series with Proteus?

I have never heard of it, so I can't say anything about it. I heard years ago that there is probably no really good replacement for the hot wire MAFs. If mine break, they will be replaced with digital hot film MAFs and I will generate the appropriate voltage with an MCU. A corresponding prototype (...

In principle, yes, but doesn't ABS intervene in engine management? Something like, if ABS regulates, then disable injection and / or ignition? I guess?

Re: BMW M70 in 8 series with Proteus?

We imagine that DME-SG I, DME-SG II and EML are no longer there and are replaced by Proteus. This means that we must either generate or respond to the following signals (from top to bottom): "must" is a relative term. For proper transmission operation, it probably just requires TR and DKV...

Ahhh, okay, I see. I have overseen this setting. What is this assignment based on? On the firing order? Those are just ordinary cylinder numbers, not firing order position.

Regarding wiring: I will make a new motor wiring harness, designed only for Proteus, completely new. The problem with the old is that the insulation is brittle and broken.

Then, the M70 has a so-called cylinder identification sensor. It sits on the ignition wire of the sixth cylinder. Due to the fact that I have no more ignition cables, I need a replacement here.
