AEM wont pick up cam sensor

[MKonmac]

I need help! i have sent my box back and it is still doing the same problems.

symptoms... (note it will start and drive wonderfully on stock ecu)

1. The car will crank and crank but not turn over
2. In the cam sensor area (not sure where this is, shop that i am having tuning it showed me) it is showing no reading. not even a small movement in numbers.
3. I remove the sensor with stock ecu it still starts but goes into "limp mode"
4. I put the sensor back on reset stock ecu and it runs beautiful.


SO i know the sensor works!

Is there a setting i must change to get this aem box working on my car???

thanks in advance

that should not keep it from starting....it usually just goes off the crank signal.....i dont think the aem even reads that cam signal

is the fuel pump turning on? manually crank the motor with the key in the on position and see if the pump turns on. That will tell u if the cam sensor is working.

silly Q did you go to setup>cam/crank>cam/crank wizard?

[ghost-1]

send me your map.

[nutz]

well basic engine is fuel and fire.....check for both....even any fuel/spark timing was off it should try to start

kinda sounds like ignition outputs fried ...or your program got a mistake, but if you tried to upload diferent base maps that should correct it

you sent it back to ems for repair??????????

Yes, the stock ecu will look for a crank AND a cam signal before it will re-energize the Fuel Pump relay. If the pump comes on WHILE cranking the cam signal is getting to the stock ecu. Note: the intial pump run when the key is on before cranking is automatic and NOT associated with the cam/crank signal

And yes of course the EMS uses the cam signal.

So whats the deal?

[never2muchboost]

what cams are in the car?you can try this

Go to SETUP-->SENSORS-->CAMCRANK SENSOR-->ADVANCE CAMCRANK-->OPTIONS-SYNC SETUP
change Sync teeth from 1 to 3

Go to FUEL-->ADVANCE FUEL-->INJECTOR PHASING-->OPTIONS-INJECTOR PHASING
change injector phase from 2 to 8

Go to IGNITION-->ADVANCE IGNITION-->IGNITION PHASING-->OPTIONS-IGNITION PHASING
change ignition Sync from 8.38 to 14.38
