Is this suitable for the 10uf caps? CGA4J1X7S1C106K125AC

Did the poking. You need a 10uf. Once i am home on Saturday I want to go over the 0805 bags I have an make the official list of what is there. If that kit is not right maybe I need to start choosing a 0805 bag better. Thanks for checking into it. I'm sorry to say the kit is also lacking any 4.7uf c...

I pulled a 10uf cap off another board I had laying around.

However it doesn't match the footprint for C103

Very cool project.

If you ever feel like posting some info and pics on the insight/eg33 combo some of us (namely me) would appreciate it.

Which one would you like or both?
Pm an address and I'll send them your way

Posting to subscribe, offer my help if I can be of any at some point and to say thanks for the detailed information.

Value wasn't included in the kit.

which values around 10uf do you have in your bag of parts?

None. 1uf is the highest value included.
I could try and stack 10 on top of each other? <--joke

Our documentations sucks. Would anyone be available to help with https://sourceforge.net/p/rusefi/tickets/344/ ? That would be a tiny step forward. I'll try taking a couple photos of mine and see how they look. Also I think my question about the 10uf caps got missed. C103 in the cam/crank pickup ar...

I seem to recall that 10k is a fairly generic value from the datasheet. I used 2x 5k resistors to get an increased stand off voltage. The 10k is primarily to prevent over current of the rail clamping diodes, as the sensor will typically see more than 5V and can go below 0V. I would agree that 4.7k ...

Thanks again. Onto the next one. C103 shows 10uf in the schematic but I dont think thats right. Its located in the cam and crank input area. Just noticed its referenced in the component options page as well. Maybe im wrong. Its just that it wasnt included in the kit and 10uf seems high for an smd cap.

Alright next minor issue.
The resistors on the cam and crank inputs are 5k but the kit came with 4.7k or 5.6k resistors.

Is this another case where substitution is ok?

R102-R104 and R106-R112 are the resistors in question.

Ah. That's good info. Thanks.

Why do you say that?

Are you referring to the ebay listing? Id like to grab one or two.

I'm still a long way off but things just got a little easier down the line.

Alright. Need a little assistance. I've got some diode issues. First is where does D1 go? Went through the schematic and can't find it referenced. Second issue. There was an extra diode in the bag containing the double schottkey diodes. The diode appears to have D96E8 on it. I've attached pics for r...

Subaru uses this method for fuel trims. They have 4 fuel trim ranges divided up by air flow. That probably depends on the year, earlier Suzukis use just one STFT, LTFT and TFT, from something like 2003 they moved to three ranges beyond that I don't have any experience. I believe Subaru started usin...

Do we know of any more detailed or lower level descriptions of how closed loop operation exist? I could look into it more later but there is a subaru enthusist website http://www.romraider.com/forum/ Theyre always working on reverse engieerning subaru ecu logic and having in depth discussions regar...

I believe OEM closed loop is typically something like this. -- Every fuel calculation checks AFR and calculates what % the fuel is wrong. This % is then added to a Fuel Error Variable (FEV). Over time you would have some %'s that are high and some that are low. So if you are operating perfectly, th...

I don't have a proper grasp of the nomenclature. In other words it's not you. It's me.

Just wanted to submit a couple suggestions for the Frankenso 0.4 schematic mmc_usb_1.sch -- W701 is referred to as jumper WJ01 in the notes. Inj_12ch.sch --- Perhaps a note can be entered stating the 20 ohm resistor value is substitued with a 22 ohm resistor in the current kit or that the value has ...

Well thats embarrassingly easy. Thanks

Made some more progress over the weekend. Got some solder paste and it works pretty well. Is there a way to allow other forum members to submit tickets or can specific topics be created for troubleshooting and submitting potential corrections for the current documentation? If manpower is needed i ca...

puff wrote:The thing is a diode in series with cam sensor helped remove the noise at start, but it could also affect the waveform (right, Jared?)

Maybe try the 2.2k resistor instead?
Would the diode clip the waveform?

What's that dual thing? It has nothing to do with crank. It's cam, and it's rotating too slowly in the very beginning that the fixed hysteresis (watchdog?) time is still too short. http://jbperf.com/dual_VR/v2_1.html Sorry i thought your issue was with a noisy crank and cam signal. It sounds like y...

This was done. Once. Two years ago

Anyone reason it wasnt pursued further?

This is relevant to my interests.

Can we put the the MCU right on Frankenso 0.4? I was wondering if i could just take off the discovery board and installmit right on the main board.

This may have been mentioned in the megasquirt post but if memory serves either the dual VR conditioner they have or a 2.2k resistor inline with the crank sensor seems to work.
