Does it have low-cam and high cam fuel and ignition tables - was browsing the software but couldnt find it.

 

AEM uses one fuel/ignition table.
There is not a high & low cam table.

 

is that an issue?

 

No.

 

There is a VTEC fuel multiplier, but I don't know anyone that uses it.

 

No one really used the VTEC fuel multiplier. VTEC is usually either on or off so just tune the map accordingly.

 

can you explain that a bit more...i am a hondata user. trying to get my head round this

 

In the Series 2 EMS there are specific points to turn on VTEC. The three most common are MAP, RPM and Throttle. Most likely if one of the conditions are being met it should be in VTEC. Its very rare you are going to be in a situation where one one would be in the VTEC portion of the map, but not need VTEC to be on. Yes there are some cases. So for instance tuning your map find your activation area and tune that part of the map for VTEC.

 

OK i understand the approach now. No issue for a WOT runs (drag)...

Can it

Switch into VTEC at 5500/85kPA (Near full throttle)

Can it switch into VTEC at say 6000 rpm (500rpm higher) at 50Kpa ( 50% part throttle)? how would AEM handle that?

 

You have settings for whatever you want to switch it over for. You can tie it all into RPM on/off, Map on/off and TPS on/off so all conditions would have to be met for it to engage.
