Datsun 1600 HFS3 upgrade

Hi Richard,

Thanks for the positive feed back. I means a lot. I have wanted to experiment with direct port and pre turbo injection for a while and finally decided to take the plunge. I followed the Aquamist manual guide lines of 1.5cc/horse power for jet sizing. In the end, i think we could have used 50-100cc (feel free to correct me here Richard) more, especially when running 100% water. The water injection only tune produced a max of 302kw but on back to back runs detonation began to creep in so timing was reduced to keep the engine safe and power on water only was capped at 291kw.

My ecu has the capability to log the flow signal output from the WI control unit. I will set it up and post the logged data.

Kind regards,
Orlando
