1zz megasquirt and emu ecu

[steve_co]

Hi im looking for a cost effective stand alone ecu im looking at megasquirt

Im getting asked "Do you know how many teeth are on the crank wheel
and what sensor it is. Also, whats the phase sensor and is this a
single pulse / cam rev?"


does anyone know the answer to these or do I need to add a crank wheel?

also has anyone used a emu engine management unit? looks competitively priced any good seen it for 500 euro

Technical details:
•6 fuel injector outputs (5A)
•6 AUX outputs (5A)
•6 ignition outputs -passive or active coils software selectable (7A)
•4 stepper motor outputs - bipolar/unipolar (1A)
•2 EGT direct inputs
•2 knock sensor inputs
•Inbuilt wide band lambda controller LSU 4.2
•Inbuilt map sensor 400kPa
•Inbuilt baro sensor
•4 digital inputs VR/HALL – software selectable
•3 dedicated analogue inputs (TPS, CLT, IAT)
•4 additional analogue inputs (0-5V)
•compliance with ISO 7637
•support 1-12 cylinders
•max rpm 16000
•injection time resolution 16us
•ignition advance resolution 0,5 deg
•knock sensing 1-20 kHz
•Speed Density, Alpha-N algorithm
•table VE 16x16, resolution 0,1% VE
•ignition table 16x16, resolution 0,5 deg
• AFR Target table 16x16m, resolution 0,1 AFR
•Injector voltage compensation
•coil dwell calibration
•user calibrated IAT, CLT
•PID idle control strategy
•boost control,
•nitro injection control;
•Aux outputs for fuel pumps, rad fan ..
•motorsport strategies launch control, gear dependent shift light, flat shift ( gear change cut)
•logging over 100 parameters
•possibility of check engine lamp
•USB communication no additional interface needed
•user friendly software with free firmware upgrade
•manual and support in English


Im going turbo thus the need for a new ecu

What do you guys think?

Thanks

Hi Steve,

I considered this solution some time ago, but for the same price I got a Apexi PFC ...

The majority of the answers to your questions can be found in the MRS technical documentation (teeth number, cameshaft sensor signal,...)
You'll find that the rev sensor is inductive (passive), that camshaft sensor is Hall effect (active) and so on.

Yep inductive crank. Also one of the points on the wheel is different so the mapped should see this and know what settings. Also just incase you just wire up and plug in, the coil packs are digital. If the ecu on the wrong setting you will need 4 new coil packs.

Thanks guys

[steve_co]

are the teeth missing at the same point so 34 (10 degree apart) then a two teeth gap?

Thanks

Not sure how many teeth but yes the tdc point is bigger.

Here is some info in the Crank Wheel..
