hello!

I just bought a secondhand EMS4860 standalone ecu from the ebay, and I'm starting to setup the ecu.

Aim = highboost with full sequential ignition and injection

But, i've run into some info I need but cannot find anywhere

Can someone help me?

I really like to know:


1)Trigger edge: falling or rising? (crank sensor)

2)Sync edge: falling or rising? (cam sensor?)

3)does anyone know the "static timing tooth"?
From the EMS manual:
Static Timing tooth:
[FONT=KOCNJG+Arial,Arial][FONT=KOCNJG+Arial,Arial]In older software versions this was called "No. of teeth after missing"
This parameter works in conjunction with Missing Tooth and Multi Tooth Modes. The ECU needs to know which tooth is the static (index) tooth. This is the tooth that is aligned with the sensor when the crank is somewhere between 15 deg BTDC and TDC. EG: If the static tooth is 5 teeth after the missing tooth/teeth or after the sync signal then set this parameter to 5.

I want to go full sequential ignition, so 4 seperate coils, how can I know if it's falling or rising?
from the EMS manual:
Ignition fire edge:[FONT=KOCNJG+Arial,Arial][FONT=KOCNJG+Arial,Arial]
This parameter must be set according to the igniter module you are using. EMS igniters and most OEM igniters work with a falling firing edge. This means that the ignition output of the ECU is held at a high voltage for the duration of the dwell period and then switched off when the coil needs to fire. Rising edge modules work in the opposite manner. It is important to set this correctly to prevent coils and igniters from being overloaded.

This would help me alot
(and maybe also others)


thanks

No one that can help me out???

Tricker, rallycing, etc...
anyone?


well, in the mean time I got even more confused

1) a lot of e-shops said both cam and cranksensors were hall-type
2) here I only read crank was VR-type (kind of inductive/magnetic sensor)

So there are 2 possibilities: or the shops are wrong, or you can choose between hall and vr for crank????

I'll set the ecu up for "MAG" (vr) as Cranktrigger and so I (according to manual) HAVE to set the trigger edge to rising

The SPI crank Sensor is VR 60-2 I'm not sure about your other questions I've not needed to look into it as I run batch using the existing ECU to supply my timing signal.

I'm sure someone who's done sequential on MS will be along to help you soon.

thanks, I guess the vr will be on the mpi too

Ain't there anyone who can aswer questions 2, 3 and 4 for me?


any of the megasquirt users?

Maybe try pming craigb244 or kritip not sure who else is using MS.
