Hondata

Thanks for your reply, I'm still kind of confused why RomEditor V3 wont work though? What version of Hondata was the S100 originally released with?

Chances are it's a sensor or a wire. But I could be wrong, I'm still new to Hondata.

In your gauge cluster, how high does the needle get for the temperature?

This may seem as an odd question to you, but how warm does the engine get?

The reason I ask is because if it's got a low temp thermostat, the engine will run cooler, however the computer will think it's cold still and it wont engage the VTEC.

Very nice power band! Good job with the build!

Are you sure it's not kicking in? It could be that your tuners did a good job and made it a smooth transition.

It it were my car I would check the wiring coming out of the VTEC solenoid and the VTEC pressure sensor, I would also check the wiring going into the ECU. Chances are you have a loose wire.

I picked up a P28 with a hondata S100 on it a few months ago. I'm using it on an Accord with an F23A1 swap converted to OBD1. I've got Romeditor 4 but I'm unable to program the chip with my Moates Burn1 chip burner using flash and burn. Maybe I'm missing something but I haven't been able to program ...
