Ecumaster forum

Hi,
I'm looking to set up my Alfa Nord motor to run sequential ignition and injection and plan on using the CAS from a Nissan SR20DET. I understand that these stock have been giving some errors in other people's builds due to the extremely fine slit size in the original trigger wheel,

To combat this, I plan on using a 12-1 trigger disc from diyautotune. These have a single Cam sync window on the outer ring, with 2 sets of 12-1 slots on the inner ring.

Is anyone successfully using such a set-up and if so, could you share your primary and secondary ignition trigger set-up tables?

The SR20DET CAS: And the diyautotune trigger wheel: Thanks & Regards,
Nick

EMU supports standard CAS disc. What is your maximu RPM ?

Hi Jakub - rev limit will be about 6750-7000 maximum.

It will work on OEM CAS disc.

Here is configuration:

Brilliant - thank you. Will try it with the original disc and worry about changing only if I have problems.
Regards,
Nick

This trigger disk is used by MOtec or AEM EMS .... But Ecumaster is better , and can very good work with stock trigger....... i made some SR engines, and every works great with EMU !

Thanks for the report Karel - It's good to have your first-hand experience.
When I decided to go with the EMU, the processor speed one of the deciding factors over the others for me, but given that the CAS-disk swap is a cheap and easy one, I figured why not make its life easier with less intense sampling rate.
But if the stock disc works fine, why not use it?
