ECU flashing code 4 plus not reving past 4k

ZC Q'S....

WHERE IS CRANK ANGLE SENSOR LOCATED?
4 FLASHES IS CRANK ANGLE SENSOR....RIGHT?

Also motor wont rev past 4000rpm...back fired once
Throttle is getting WOT

The two white wire that are added during a SI to ZC swap do nothing.. If there connected and you un do them there is no difference in the motor sound or performance..

well, first of all what distributor are you running? you need a 88-91 Si, HF, or EX distributor. The Crank Angle Sensor is inside the distributor. Your right, the two added wires don't do dick without the right distributor, I had the same problem, except i have a JDM D15b in a 91 hatch. Also, make sure you switched the grn/wht and yel/wht wires on the TPS Sensor. If you have any more issues let me know. I know how you feel, I've gone through it.
