AEM no Stat sync, live cam power feed
Hi all,
We have recently run into issues starting our project S2000 after it being fine for a good while and nothing has changed in the set-up.
The issue has baffled me, AEM, Rywire and our very knowledgeable tuner.
So just a brief insight into what's going wrong and what we I have observed.
The car is a 2001 model running AEM series 2 ecu and a Rywire Mil spec engine loom to ecu via mil spec firewall connector. Car has started fine ever since the dyno tune in October of 2012.
The car now however will not start.
- Cranks Strong
- Fuel pump can be heard priming and fuel pressure to rail and injectors
- Battery is at 12.89V
- Cam and Crank sensor resistance checks out to workshop manual spec
- Cam and crank sensor continuity check from sensor plug to ecu good
- Coils are getting voltage
- injectors are getting voltage
Problems noted
- Cam sensor has live feed even when ignition is off of full 12V
- related pin on ECU is giving out 12V feed to that pin on the cam sensor plug when ignition is off
- AEM tuner software (When connected to ecu and cranking) Shows no stat sync and ignition errors on each crank revolution.
Does anyone have any ideas of what might be going on.
Sent ECU and loom back to AEM and Rywire respectively and they both checked out fine apparently.
I'm at a dead end now as tried everything I can think of.... Thanks for any help in advance.

Get it fixed?
Get it fixed? Currently having the same issue with my Aem. Car drove fine for couple days after tune. Now the car won’t start and stat sync is off. Added 0.02 to both cam and crank h and l levels. Still no start.

I am dealing with this also. Posted on the AEM forums and one of their tech guys pointed me toward another thread which helped greatly. I had to go in and change VR PWM Duty from the default setting of 60, down to 20 and now it starts pretty reliably. It still cranks longer than what I think it should, before starting, but at least it starts.
