[rusEfi] frankenstein 0.11 on nissan sr20ve neo vvl #34

[kb1gtt]

To measure 12V on Frankienstien R0.11, I would suggest installing 10k ohm for R321. On Frankenso it uses BOURNS,CR0805-FX-1002ELF

Then install 39k ohm resistor in P209 position 6, which is for CH12.

Then connect your 12V to the other side of this resistor.

Then add the jumper wire noted below.

At this point you should basically have the same setup as the default Frankenso.

I believe @ is already using channel#12 for hall sensor conditioning, so he would need to use some other channel for VBat. Channel #10 maybe?

[matt]

i think orange wire is suitable with Rusefi theme.

Any color wire would work!

As long as it's orange.

[kb1gtt]

The orange wires have a lower optical friction coefficient which makes the electrons flow better. It's good because the electrons don't get stuck in the low parts of the wire like other lesser wire colors. Remember, buy it because it's a better ECU.

its start with my mitsubishi just now.
but it seems too much fuel injected. i use same setting with frankenso with different set with io pin.
spark and injector check, all at right way.
warning code appear CUSTOM_OBD_ANALOG_INPUT_ERROR = 6038,

[AndreyB]

Code: Select all

	/**
	 * This error happens if some pinout configuration changes were applied but ECU was not reset afterwards.
	 */
	CUSTOM_OBD_ANALOG_INPUT_ERROR = 6038,

[matt]

it is possible my engine get flooded cause by fake mosfet?
i get those mosfet from aliexpress.

[matt]

looks like my VNS14NV04 is going wrong. i can see some heat mark on it surface. will it work if i change it to STP62NS04Z? i can source it easily with local online order.

[matt]

hmmm.. i think i get VNS1NV04DPTR-E.

i check with multimeter and got continuity between pin 5-6 and 7-8. with vns14nv04 it should be continuity at pin 5,6,7,8 and pin 2,3,4.

[matt]

issue solve. i change all injector driver, taken from my frankenso.
engine start quite fast then frankenso, and can pull over 7000rpm.
so this frankenstein will be my daily drive ecu on my proton wira.

[AndreyB]

Still owe you 4/360 trigger which I believe we need to get better timing precision during fast acceleration.

[matt]

no worries, and take your time. iam not urgent to use that.
planning to use this frankenstein on drag race car on will be held 5/2017. i involved in tuning and ecu, my friend working on engine and others sponsor for a car chasis. we are working with 4g93 sohc.

where should i get EFI stickers? planning to stick it at the door.

[matt]

one more thing. iam planning to do a alternative injector driver using this http://www.farnell.com/datasheets/1690219.pdf?_ga=1.164089407.100422501.1434427476
can it drive directly, lets say PE4 on stm disc or need to put some resistor?

[kb1gtt]

It appears that Rg should be at least 4.7k ohm. I would also suggest a pull down resistor, similar to Frankenso R0.4 resistor R404, ect.

Beware the clamp diode between gate and drain. This clamp will dump significant energy into your GPIO pin. I see VGSS is 18V however your GPIO will clamp to about 5V. During these clamping events, you will have current through Rg which will dump to your 5V rail. You need Rg large enough to allow for an 18V gate voltage while not destroying your 5V clamping diodes in side the STM32. As well the mA's that are dumped to the 5V rail need to be consumed or your 5V will raise and damage chips on the 5V supply.

Using this chip will require electrical tuning on your layout to ensure it does not break or fail.

According to the datasheet, Gate threshold voltage = 2..4V, so it's not guaranteed to be logic-level (3.3V max). It may not saturate completely when opened...

i not completely understand, but consider not to do this.
if it possible to use VND14NV04 same as @andreika using in his board?

[kb1gtt]

Yes VND14NV04 is the same as what is used on Frankenso. The chip used by @ is simply a thru hole package instead of SO8 SMD package.

[andreika]

Not quite thru-hole but yes, it's just in a different package - "DPAK". You can use exposed copper area with multiple vias on pcb as heat sink for it's thermal pad.
DPAK:

[kb1gtt]

Yippee! DPAK. That's a good choice, it has a lower Rth than the SO8 package which makes it easier to keep them cold. I figured those vertical thru hole components were the injector chips. I guess those must be the ignition chips. Or who knows, perhaps those chips are simply a slightly older picture. Either way, yes it's a good choice.

Sorry, I've aswered in 'Prometheus' theme, for fear of digressing from matt's topic...

[matt]

got question from my friend running with BMW e30 M20 v6 engine. could it run with rusefi? AFAIK it is with 60-2 trigger wheel.

[AndreyB]

Inline-6 probably? Yes sure, we had two of these BMW running. The recent one is http://rusefi.com/forum/viewtopic.php?f=3&t=1099

[matt]

can 60-2 do sequential? from my understanding, it need a cam signal to run sequence.
sorry for noob question, just wonder how the cam signal is sync to run this.

[stefanst]

You are 100% correct. A 4-stroke engine needs a cam signal to run sequential fuel or spark.

[kb1gtt]

Yes the ECU needs to know 360 vs 720. With out this knowledge on a 4 stroke engine, no ECU can do sequential. You would have a 50% chance of injecting on the wrong stroke.

[AndreyB]

And if you have a simple cam sensor with just one tooth you can use it with your existing 60/2.

But there is an opinion that you probably do not really need sequential.

[matt]

so if with 3 cylinder it will do sequence with 60-2/36-1 crank tooth? or still need a cam signal?

[kb1gtt]

Do you understand what sequentail is? Please see this wiki page http://rusefi.com/wiki/index.php?title=Engine:acronym-phrases#Sequential

If the ECU does not have knowledge of 360 vs 720 degrees, you can still run the engine. However it will not be sequential, as it would squirt when intake is both open, and closed.
