I had the same issue and my fix was to simply set at 0% the rows that are below 1000 RPM in both the "EAE SOC RPM %" and "EAE AWC RPM %" curves, effectively "disabling" the EAE correction when under 1000 RPM.

Oops, I think I deleted the file in my Dropbox. Fixed :

About the math, I'm not sure it is accurate.

I would do it this way :

Global Fuel Correction = ((FuelTotalCorr / 100) * (FuelEGOCorr / 100) * (FuelAccelCorr / 100)) * 100

Just to add to the technical side of this discussion, here's the reason why you want to set your end of pulse earlier and earlier as RPM rises : - The fuel getting out of the injector is atomized, but not vaporized (so, it's still in a liquid phase) - You want this fuel to get some heat from the air...

The PID for a drive is different to boost. With a drive your output is likely controlling the voltage or current to the servo motor. This determines the speed (or force?) that is applied. When you reach target the motor is stationary. The voltage/current is effectively zero. With boost, the output ...

unless the bias(feedforward) will adapt(learn), setting the I_sum to 0 will prevent the boost from converging on the target. What drive were you tuning? (I did a lot with that sort of hardware in a past life) B It was a AMC drive controlling a frameless brushless 6kW 400VAC 3-phase motor : https://...

If the problem is with the I_term, instead of "removing" it during spooling, why not setting the I_term_sum to 0 when you are within an interval around the target? This way, any I_term_sum that would have accumulate during spoolup would be reduced to 0 once target is attained and there sho...

My only oddness is that I have VREF pulling up ALED and WLED to run the other two coil triggers for the QuadSpark module. Using 100Ohm resisters per the manual. About that, the Manual is stating 1kohm pull-up resistors to Vref for ALED and WLED, not 100ohm. If you used 100ohms, then there might be ...

It's been a while since I played with MS stuff, but, if I remember correctly, the blue bar you are talking about isn't a progress bar for a calibration process. I think it is just a graphical representation of your throttle position. You can ignore this blue bar. Simply press "Get Current"...

I'm assuming that the gear ratios and the wheel diameter are known values and are correct for the engine/transmission you are using. Then, it's just a matter of finding the correct "pulse per km" value of the speed sensor. I would suggest you to do a log at a known constant speed (ex : 100...

Also, just make sure that your head is correctly grounded to the battery negative terminal.

It would be better if you could upload a full log. We would be interested by fuel PW and and all the associated fuel correction factors.

Are you using large injectors (where PW at idle would be lower than 2.0ms)?

Sam

What "other contributing factors" You mean? These values are from the manufacturers datasheet. Offset = 0.64ms = DeadTime (like red line in the picture show too). And this my calculated DT 0.59ms at PW 2.5ms also is close to curve (DT at 2.5ms is slightly smaller than the red line indicat...

And example... (from DEKA datasheet) Opening Time = 1.5ms Closing Time = 1.3ms Offset = 0.64ms And calculation ... 27.8g/s => 27.8mg/ms 2.5ms pulse = 53mg DT (at 2.5ms PW) = 2.5 - ( 53/27.8 ) = 0,59ms The green scale and red line are not very accurate.

So then what is the reason for pins 8~14. And I've also seen a post from you that states "Internally all of the ground pins are actually the same. So any spares could be used as a sensor ground". The confusion continues.... As said, yes, all the pins #1, #2, #7 to #19 are all ground wires...

For a strain relief, the only one I could found that fits the TE AMPSEAL 35-pin connector is this one : https://www.te.com/usa-en/product-776463-1.html Unfortunately, it is a "straight" strain relief, it doesn't offer the 90° bend you are looking for. I think that a bracket with a few tie-...

Hi, I would suggest Amphenol AHDP series. They are circular 47-pins. They are using the same Deutsch pins. This one is panel mount : https://www.digikey.ca/en/products/detail/amphenol-sine-systems-corp/AHDP02-24-47SR-SRA/13917107?s=N4IgTCBcDaIIIAkAiAFADGAtGALJnA7AMoBKmpcIAugL5A And this would be the...

I've used Google Chrome Remote Desktop : https://remotedesktop.google.com/

The only requirement is that you have a Google account (Gmail?).

Works fine.
