Hondata

Hello guys.
I really need your help.
I have 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.

Help me please, i really need my car and i`m in dispair.
Thank you.

That knock board in that ECU is tuned for a 1.6L engine, not a 2.3L engine.

Without a datalog and your calibration it is impossible to speculate on what is happeneing with the o2.

You must disable those errors in the software and upload the calibration to the ECU with those errors disabled.

Again without a datalog showing the problem and you calibration it is impossible to say what is going on.

Have you contacted Kaizen Speed about these issues?
