Re: Mercedes M104 install

It's running but I've had to put it on the back burner for now.

Needs to be tuned.

Re: IDLE not working

idle output is a float value with a lot of precision, it's the gauge which had no decimal ponits - one digit after the point added. period, verbose and offset clarification added - let me know if it's not exactly undestandable or maybe suggest some better wording if you see what I mean but you thin...

Re: IDLE not working

The Bosch idle valve is very common and is used on bmw's, volvo's etc. Normally 120-200hz pwm is used. It is a spring loaded rotary valve. I've used this valve with microsquirt and Haltech elite 750 and it works very well with those ecu's with virtually no tuning. This picture shows it working with ...

Re: IDLE not working

there needs to be higher resolution for the output as it changes in whole percentage points, it needs tenth percentage steps. resolution where? on some gauge or where _exactly_? which _exact_ setting do you think need more explanation? I thought I was clear that the idle output needs to be higher r...

Re: IDLE not working

After a lot of trial and error I found settings that work ok. There are still some issues though, there needs to be higher resolution for the output as it changes in whole percentage points, it needs tenth percentage steps. There seems to be no way of opening the idle valve after a rev and the engin...

Re: IDLE not working

Ok, I got an output using PD7 LOW1a-03, looks like PE6 output is faulty with my board. And the test page output for idle valve does nothing.

The motor revs up but stalls as the rusefi over corrects. Are there known values that work for the PID on the Bosch valve?

IDLE not working

Hi, I have no output for the idle control. I have a BAC that standard on Mercedes. I wired it 12v one side and the other to INJ-01(PE6) and there is no output from rusefi. I've tried PE5 and PB7 and there is no waveform output from rusefi. I'm using an oscilloscope to test. When I try the idle valve...

Re: Mercedes M104 install

I started the car today no problem , I'll shoot a video of it running tomorrow.

It seems the idle isn't working so I added the shunt diode but ran out of time to see if it made any difference.

Re: Mercedes M104 install

The M104 is a K-jet mechanical injected motor.
So there is no ecu connector to chop into.

I've made a fuel rail and TPS adapter and also using 60lb Siemens DEKA injectors.

Re: CAM speed trigger input

Hmmm, perhaps "4 storke primary = 360" or "4 stroke primary = 720" I kind of think that there should be some rusEFI specific acronyms. Perhaps acronyms like P rimary E ngine A ngle D ecoder (PEAD) and S econdary E ngine A ngle D ecoder (SEAD). Then the comment could note "4 storke PEAD = 360" and "...

VVT on Mercedes M104

I've read through setting up VVT for the Miata and it looks like Aux PID is intended for controlling VVT. The VVT on the first M104 motors is an on/off solenoid, there's no variable control. When driving, under load the cam advance happens at 1500 rpm & goes back to retard at 4200 rpm. Could someone...

Re: CAM speed trigger input

Try putting a box around your printer, such that the air does not move around to much. This prevents the part from cooling off to quickly, and helps with the new layer adhering to the older / colder layer. This box also helps prevent your part from cooling to quickly. When it cools quickly it has a...

Re: CAM speed trigger input

Ok, I confirmed what you said. I setup Ardustim to output a 36-1 trigger pattern into the CAM input and rusefi sees it as double the input. ie, 1250rpm input equals 2500rpm at crank. I think if you reword the dialogue box to CAM speed or CRANK speed input or sensor location it would be clearer. ruse...

Re: CAM speed trigger input

Yes, I've seen that but there is no speed setting so the rusefi won't know if it's crank or cam speed. So you do not see "operation mode" and the options in that drop down do not ring a bell? "4 storke with crank" vs "4 stroke with cam" what do you think this is about? Do you think the labels are n...

Re: Frankenso - ECU shield compatible with OEM case / official

Let's take injector 1 for example. It uses PB7, so we have to look at the schematic to get where PB7 goes, it's inj-12, which is low-1a-12, then we have to look at the pin out, which looks like it lines up with W63 or is it W64? Next one is battery voltage, I have 13.1v going into it from the PS, b...

This 36-1 at cam speed.
