ETB works quicker than i was expecting so can probably adjust that a bit higher. Yeah - it's just about as quick as you can get, save for a hard fuel cut. I have my ETB limiter set to start limiting near where you should shift, and hard limit between that and the "parts start falling off"...

Looks like your wheel is a bit custom image.png your first ratio is around 3.2 so let's do from 3.2*0.75 to 3.2*1.25 so from 2.4 to 4.8 your second gap ratio is around 0.3 so let's do from 0.225 to 0.45 Nope - that's not what you want. The N-1th gap is actually the 1.0 gap just before the long toot...

hi?

do we know what messages need to be send when?

we do not, I would have done this by now if we did

I have one of those pumps on my endurance race car. I run it in the mode without CAN and it works totally fine. Almost undetectable that it's not the mechanical pump on the engine feeding the rack. I'd also be interested in making it talk over CAN, but to be honest I'm not sure of the value. It work...

Hey @tmbryhn, I've added an option in the advanced trigger page to ignore the cam sensor above some RPM. Give that a try with it set to maybe 1200 in your case?

There are some more improvements being made in this area - will keep this thread posted.

To answer your real question, instead of answering a different question as Mark has done: We don't currently support connecting a serial NMEA GPS to the ECU, no. While technically possible, we don't really want to parse NMEA on the ECU itself, since it's some extra work for the CPU (it's busy enough...

What wideband controller do you use? Anyway, probably yes, you can at least test that the sensor shows very lean while sitting on the desk. You can hold a lighter up to the tip of the sensor (lit or unlit) and you should see a response.

But then I found what seems to be an issue in the AuxLinear software! ... This is showing they're using the same calibration. I didn't have them both assigned to the same pin simultaneously, I was switching between the two inputs on the same pin. The aux linear outputs can only represent values bet...

Eh? We see much better performance than that on ECUs. Down in the single-digit millivolt range.

ps: nice HP scope

so, do I get it right that the hip9011 solution has now become officially obsolete in rusefi? In theory still works, but I can't recommend it after the success we've had without it. in this thread there are two almost similar schemes - with mcp6004 and with two LMV321IDBVR - which one is better? wh...

How much timing pulling are we talking? Can you adjust the linkage so that 1% is actually fully closed, but not on the mechanical stop yet? The point of the 1% limit is to prevent jamming the throttle against the hard mechanical stop (same at the high end) to avoid integral wind-up.

Do you need the cam sensor at all? May be more reliable to just run wasted spark instead and ignore the cam sensor completely. Your crank sensor looks perfect. What's the cam drive like on this engine? Do you have any control over the relative phase between the cam sensor and the cam? (try turning i...

One issue I found is that the wideband isn't reading and it's in open loop. I set the close loop fueling turn on to 40C TW and 30sec after start. I let it warm up to 60C TW and then shut it off, since the new header wrap started smoking. It's a brand new LSU4.9 sensor from Ballenger Motorsports, so...

The trigger wheel is located on the crank between the 4th and 5th main bearings. Modifying it to remove teeth would be messy and difficult.

Wow

Same as an LS. My trigger wheel is pressed on to the crank, and the sensor goes thru a hole in the block behind the starter.

I see that you are already using "Enable noise filtering" which was supposed to help at least with some physical noise.

I don't see that? Leave it off. Don't need it.

Turn off "Print verbose trigger sync to console", though. I bet $1 that's the issue.

Just a note Andrey that the Legacy console, thinks the 0.2 proteus board is F7 and won't let me DFU. I downloaded the F7 Firmware and used the console from that package to DFU then used the correct Legacy firmware and it works. Not sure how the consoles got mixed up. We recently switched that, shou...

can you share that mlg and a TS trigger log of it happening?

Or even use 24-1 or 12-1. Those lower tooth count wheels should run a 17k rpm engine without issue. We regularly do 6-8k RPM on a 60-2 wheel, which is actually more teeth than 24-1 at 17k.

For simplicity of configuration, try turning off all cam sensing stuff first. Disable the cam inputs, set the cam modes to NONE. Set ignition to wasted spark, it should run totally fine that way.

image.png These settings say: - Set idle position to 28% * CLT adjust table - Add 5% if AC is on - Add 100 RPM to the closed loop target if AC is on - Add 100% if fan 1 is on (?) That last one doesn't look right to me - do you really want to add 100% (ie, max the idle valve fully open) if the fan i...

Set "enable faster engine spin up" to true on the cranking page. That will run the engine in wasted spark mode until a cam tooth arrives and "resolves" the engine phase. You can also run the engine in wasted spark mode with "two wire wasted" mode enabled. That will let ...

can a small mosfet be used instead of BC337 in this case? (with a flyback diode across the coil)

of course

How big are the trigger wheel teeth, and what did the sensor come from? Roughly same size teeth on the vehicle the sensor came from and your trigger wheel? If not, that can cause problems with the signal from the sensor being poorly matched to the wheel.

GD -
Is USB still a primary way of communications with TS / devconsole?

Not a gd32 batch, just an experiment

When it cuts out I'm pretty sure the ECU thinks the crank is a full revolution off its actual position as it continues to fire the ignition and injectors just on the wrong cycle. can you try it on wasted spark? -Swapped the VR wires. The waveform doesnt look right but with the wires swapped the mis...

One idea is to read SPI at ~1mbit/s in to a buffer, then post-process it instead of trying to process edges in real time.

It's sort of a hardware issue too. SENT is a real pain in the butt to try and decode in software.

Legacy TB will bolt up directly, no issue there. I suppose I could make a short jumper harness from the throttle body to the ECU, bypassing the current harness.

Do this.
