Hi all.

I have some problems that you can help me to solve. I hope so.
h23a vtec (blue top) engine and Kaizen Speed ecu (37820-p30-010) with Hondata s300j v2. Civic EK 99. Use prelude H22 basemap.


1. My knock sensor (stock H23A), when i start engine KS outputs in sManager 5v always, but it doesn`t look like detonation. If i unplug KS it shows 0.09v.
2. My narrowband O2 (4 wire) sensor always shows 3.77v but harness is okay.
3. When i start engine - CEL. ELD (20) and Injector (16). I just can`t figure out, p30-010 jdm doesn`t support eld and injector test and i just need to disabled errors in hondata or i just have bad ECU.
4. If i disable eld and injector error, ecu doesn`t throw a cel but redline at part open throttle is 3700. At 70% and wider open throttle redline seems to be fine.

Thank you. Sorry for language.

 

Sounds like you have an ECU that is messed up, a fake Hondata unit, or a chipping gone wrong.
