Honda CBR600RR fuel injection

[AndreyB]

I have no idea My best question is - how are all the wires connector? Do you have alligator clips on the sensor plug? How is the pigtail extended - soldering or no soldering?

I have no idea if this could be the source of the problem

For VR I expect W1002 and W1003 to be open. I see they are shorted with a 0R resistor. I would suggest removing the 0R jumper.

Historically all VR I've seen running have one wire GNDed.

It notes

In Mode A2, an internally generated reference voltage is used to bias the differential amplifier and all internal circuitry instead of an external
voltage connected to the BIAS input—this helps reduce external components and design variables leading to a more robust application.

So I expect the internal switch to connect IN#+ to 2.5V and then when ever the IN#- crosses 2.5V it toggles the output. However we also have the bias pin connected to GND. If it were a different mode, then I would expect the external bias to be used, and if that happens then I would expect you want to connect IN#+ to GND and detect when it crosses the 0V level.

I think I'm hearing that for some reason, it's using the external bias reference. That seems odd to me. Any how, if it works it works. I wonder why this one is not working.

Perhaps try soldering a big fat wire from a GND point on the Frankenso, and run one to the engine block, and another to the battery negative terminal. Also run a GND wire between the engine block and the battery negative. A good ground connection is required. Make sure the contacts are clean shinny metal. Also keep in mind that with 0 RPM the 85mS watch dog will crank up the gain. This can make it more susceptible to noise issues. You might see noise issues go away as soon as you start cranking the engine.

[AndreyB]

Here is my Frankenso with one channel set for VR (i.e. one wire GND using two 0R resistors) and 2 meters / six pieces of twisted wires with no shielding and some random VR sensor and waving a piece of metal. Zero RPM in case of no activity, usually noise reading in case of wire touching and somewhat high RPM reading in case of metal waving.



@Kavabanga can you please reproduce this? Maybe get a new cheap VR sensor from a parts store? Shorter wires? Not sure what else could be different

Did you connected sensor by left or right channel?
You connected to console by mini-usb on Frankenso or by micro-usb on STM32?

[Kavabanga]

Regarding the VR sensor - That looks like you might be able to stick a Bosch Hall sensor in the same hole as you cam sensor. What diameter is it and I will check one of the Bosch ones I have kicking about.

Hello! Sorry for big delay
I measured some Camshaft VR-sensor parameters: core diameter of sensor is 20 mm, length of cylinder of core is 40 mm

left channel
microUSB on stm32

[Kavabanga]

Hi everybody!
So, today i tried to connect console to Frankenso by micro-usb on STM32 (Usually i make it by mini-usb on Frankenso)
1. If i connect just crankshaft position sensor, console is printing, that RPM is 0. If i try to rotate engine by electric starter, RPM still be 0, i dont see nothing in "engine sniffer"
2. If i connect crankshaft and camshaft position sensor, party time is start! Console is printing me "Noise" in RPM value, but engine isn`t rotate. If i try to rotate engine by electric starter, i can see that pictures.
In this pictures you can see what i can see if i try to rotate engine with different values in "Engine sniffer size" and "Frequency"
Is it normal picture for triggers?

[AndreyB]

I have changed trigger definition for "Honda CBR 600" trigger, please adjust your setting to use "Honda CBR 600" trigger

Ideally your engine sniffer would be showing this:

[Kavabanga]

So, what i have now:
If you remember, i had a big problem with noises from VR-sensor on cam- and crankshaft.
Every day i tried to solve this problem, make something thith that. But always had troubles. And today i just tooked two resistors, which was near my hands on my table. I don`t even know they nominals. So, i tooked resistors and install they parallel to the sensors. And noises was disappeared... And now it works good! I think... Because i haven`t tried it on the engine yet. Just with metal bolts
So, maybe somebody now, what nominal of resistors is better for my sensors?

[Kavabanga]

Hi everybody!
This is what i have now (look at the pictures)
This data was recieved then engine was rotated by starter. And, despite fears, RusEFI "can see" all teeth on crank- and camshaft. That`s great! But resistors parallel to Honda VR sensors are necessary.
Also, RusEFI can receive data from ECT. But ECT has three wires to connect to Honda ECU, but RusEFI need just two wires from this sensor to good work (one wire to desired pin, one to ground). Now it is magic for me, but it works good and data, which i can see in console and Tunerstudio is true.
So, now i am waiting then my colleague will make carbon receiver and waiting for Innovate
I hope, all what i will make later will easy and my engine will start and work good.
@Russian, thank you very much for support!

[AndreyB]

Some sensor unit have two sensors integrated in one body, for example one provides analog data for gauge and another provides a switch for fan relay.

Your pictures seem somewhat close to expected, looks sweet!

You do not really need Innovate WBO to start your engine. Do you really need intake to start the engine? Can you throttle it somehow on a temporary basis?

[Kavabanga]

I have just one engine And I made solution, that i will start engine with intake system and WBO, because i have some fears about safety of trying to start engine without intake system and WBO...
Is innovate LC-2 good choice for my project?

[mck1117]

I've heard not great things about Innovate's reliability. A few of us here have had good luck with AEM's wideband O2 sensors and gauges. They make both standalone controllers (no gauge) and integrated gauge+controllers. The gauges include an analog output that you can wire to the ECU so it knows the AFR too.

I'd start the engine without a wideband (which I've done before), but you probably need an intake...

[Kavabanga]

Thank you for your advice about WBO. I asked some questions my acquaintances, who understand in WBO and already ordered Innovate LC-2. How long and properly it will work, i`ll know later
I really fear "kill" my engine and i will wait Innovate and, while it delivering by post, i`ll make carbon intake system

[AndreyB]

I have the full manuals/schematics if needed.

is that because... you maybe have a 2007 cbr600rr yourself?!

[AndreyB]

38770-N1A-D11 would be a tuneable OEM Honda part for this engine?
