R32 - you keep saying its the complexity / user error that is the problem with the AEM.
It is quite clear that this is not the case and that the AEM is unable to reliably read the nissan CAS. That is without mentioning the AEM CDi units that fail, the Scooby AEM ECU`s that stall when the case is earthed etc etc.
As it stands I would not go within 100miles of an AEM ecu for well proven and potentially catastrophic reasons.......
what about the irratic ignition??
I would never ever ever run that on a big power engine... according to the graph that Hugh Keir has, the ignition can be + - 10degrees... it will result in detonation, and in the end kill your engine....
No performance engine ECU should take crank position from the camshaft. There is a whole list of ECU's that don't recommend using the CAS for crank position. The AEM works as well as you would expect using this system.
Obviously I'm speaking from 1st hand experiance. I don't know why others don't have any sucess with the AEM, hence my comments.
After a tipoff from a forum member, I've found someone who actually knows about the AEM and has worked with them for over 4 years. I have every confidance with the AEM as long as its in the right hands.
R32 - yet again! - "No performance engine ECU should take crank position from the camshaft" - I assume you mean apart from Nissan OEM, Apexi PFC, HKS F-con pro etc etc etc.
"There is a whole list of ECU's that don't recommend using the CAS for crank position. The AEM works as well as you would expect using this system" - Errm except it clearly doesn`t!
I do agree with you in principal that belt drien CAS is not ideal BUT the AEM is sold as plug-n-play. Not plug`n`play - have endless starting problems and potentially destroy you engine then change to crank-angle sensing direct........
