99 cobra fluctuations in my timing.

I have a bone stock 99 cobra that has a flat powerband at 4000k rpms after the car is heat soaked. So when the car just reaches normal operating temperature it has lots of power and 14 to 16 degrees of timing at wot to the redline. When the car is heat soaked and i stab the throttle the timing jumps down to 0 and then goes up to 4-6 degrees with honda civics passing me laughing at the cobra. Help me.

Does it have an aftermarket tune?

All stock even the tune

Bad Crankshaft Position Sensor? Bad ECU? Just throwing ideas since I know you've had this problem for a while.

Crank sensor , engine wont start , cam sensor will cause this to some extent .
Need to test the wiring to those and the knock, at the sensor and the ECU.
I dont believe there is a problem with the ECU, but you are not getting full timing .

My first guess would be the knock sensors. You should be able to monitor the activity through a datalog.

I can only see in realtime my timing. I cannot see any data about the knock sensors. What do i need to do to see ks info?

So should secure those sensors in oven mitts and see what happens? Or just electrical tape them to the wiring harness?

Justin , if I was going thru all the work to get into the KS, I would just replace them .

Makes me worry that i will get the same results, if I tape them up to the harness it would isolate them, I think. I am just at a loss, i am leaning hard on getting a tune to turn them down.

I got 2 new knock sensors comming and putting in a 187 degree thermostat. Will keep yall posted
