Datalog - shows 3 ECU Resets, 2 PW drops to zero at idle, and one trigger error

Please post uptodate config dump so it can be examined for output-collisions or other potential configuration problem.

I think after harness tests we should send you replacement ECU to see if it behaves (should also be tried with same config).

The config dump is extremely important, the first step of the procedure.

If the replacement ECU fixes it we'll have to dump config from that too and compare to find out.

11/18/08 - Engine is running. I had to rotate the ignition outputs.

NEW Order: h[2]=10 76 60 30 20 50 50 50

'''In MT = 2-3-6-7-1 (bottom to top)

OLD Order: h[2]=76 60 30 20 10 50 50 50

'''In MT = 1-2-3-6-7 (bottom to top)

'''I assume this is because of the secondary trigger placement.

Can someone check the rest of the config to make sure it is correct for a 3B engine?'''

OLD dumps below - secondary trigger was "disabled" in MT(fixed)

Primary Trigger Settings, note no "crankminper" setting, does this explain the trigger error? (should be ~2600 for 8000+100 rpm limit)

2 Analog Inputs, custom connector


Launch Control and Shift Cut Setup

As you see, the "AAN ECU extra connector pins" has 3 analog inputs, we use one brake-light switch mounted under clutch (and a series switch that can disable it) to pull down (activate) the (shared) input for shiftcut and launch.

When activated with TPS < iac_tps_threshold launch is activated (TPS can be pressed after activation). Otherwise shiftcut is activated.


WBO2 Configuration

SSC Pin - Flying Lead - WB02 Pin


Suggestion - make WBO2 wire colors match the LSU4.2 sensor

SSC - Color - WBO2 Pin
