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

We are planning to use VEMS v3.6; currently selecting the right options.

I made a list about the options, and with the possible choices:

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)
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 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
Service maybe yes
Special request now, we have just initial questions, so we have not got any request
With SD card internal or removable: I thought it is only for logging datas, then what is the difference between the two options?

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").

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:
