AEM EMS 4 1.6L CAS Question (SAV?)
I have an EMS4 and its on a 90 1.6L miata.
I am ONLY running a CAS and using that to time the motor through the ECU. I do not have a crank trigger wheel.
The biggest problem is I don't know which CAS to select from the options in the AEM software.
I'm pretty sure we wired the CAS correctly but anyone have any other suggestions they would be appreciated. My understanding is the 1.6L miata can supply a cam and crank angle signal to the ecu. I was under the impression that the 1.6 does not need a crank trigger wheel to run.
Anyone with any insight on this would be greatly appreciated.
Thanks

Don't have the AEM software in front of me to look at, but if there is a 4G63 option, you can use that. The DSMs used the same sensor and since its a more popular engine, there may be a preset in AEM Tuner.
Another option that will provide a higher resolution trigger is to use AEM's 12+1wheel in the cam sensor. Part #30-8760 is a direct swap for the stock 4+2 disk. This would allow you to use the 12+1 pattern that is popular with the AEM ECU.
