UPDATE:

DATE: 23 August

I have just wired up the crankshaft position sensor (CKP), and while watching the "Primary Trigger Settings" I can not find an N-3 in the missing tooth option.

I have counted it many times, but it is still 12-3 type

What do you say, could I resolve it?


Date: 12 august

So I am going to write down all the information, I collected so far, using my notes.

Parts, we have already ordered from vems shop:

VEMS pinout in table (hungarian)

https://drive.google.com/open?id=0B3aVOJowc-6nMk5HUXQ4U1ZoSTA

FUSES:

COP pinout:

(normally pin2 and pin4 are joined)

LCD:

And finally, our options, when ordered VEMS ECU:

Question Nr.1: I heard, that some injector require dashed signal, some require continous signal from ECU. How do I know, which is correct in our case?

Question Nr.2: Which type of diode should be used with the relays?


Preparing VEMS v3.x install;


08.05.

So now we are on the way, to build up our bike. Some VEMS parts like EC connectors, WBO2 (LSU4.9) sensor and some relays had arrived. have already tested the TPS and IAT sensors with DMM, also tested the IACV, which is a 4pin stepper motor (R=110 Ohm).

Successfully bought a Coil On Plug transformator, which fits well to the engine block.

We are also planning to use a Mechatromotive Racing LCD, which communicates through AIM with VEMS.

Question nr.1: measured the resistance between the 2 CKP sensor outputs, the resistance is the same in both direction, 236 Ohm, so it is a VR type. Please, confirm, if I think well.

Other questions, not very important, only for future improvements:


So the questions are:


I would like to use oil temperature and oil pressure sensors:

I found these ones suitable (for pressure):

(I need only one of them)

For temperature, what do you prefer/offer?

I am thinking about using a VW Bora 1.8T ignition transformer (stock number: 715459 0040102043), but I need a 10mm shorter one.

Do you think is it okay to use this on a motobike engine or use some CDI driver? Or what do you recommend?

VEMS supports shiftcut, yes. Input can be shared with launch, or separate (or when launch is not used => of course "separate").


We are building a custom bike, with a Honda CBR250R (2015) engine (1 cyl, 250ccm).

1-wire interface not needed
EGT-input (exhaust gas-temp. input)maybe yes, but not essential
ETC BridgeOutput Interface no need, we have manual gas control (with bowden)
Flyback type still do not have certain information, just the type of the injector (Keihin 0660 52219 FBBJF). Still no DVM to measure resistance ?
Hi-side PFET outputs no
Ignition driver yes, 2+6 (cost-effective and the most suitable for one cylinder)
Knock input channels no
LCD connection yes
MAP connection offboard. We have a Keihin sensor unit (with 5-pin connector) for that, still don't have a datasheet, just serial numbers: 5318A (includes MAP sensor, IAT sensor, TP sensor)
Mounting-styleflanged case is good
Primary trigger VR (I have found the stock trigger as inductive, then it is suitable, isn't it?) 12 toothplaces, 3 missing
Secondary trigger no, we don't have camshaft position sensor
Special request now, we have just initial questions, so we have not got any request
With SD card "removable" is removable, to plug in another card in 3 sec, or for quicker download data to PC
