Fuel economy Q

[steve shadows]

Honestly the best way to really really GET THE MOST out of your fuel economy is to take full control of your fuel and ignition maps

I suggest investing in a Power FC L Jetro unit.

Then reducing the fuel injector time on the low load cell portions of the map by 15% in every cell up to 4K rpms and eveywhere below load cells half way up the map. This should yield cruising AFRs of around 14.8-15.0 and also more low end torque.

Also I have found that the factory OEM Timing maps are WAY too advanced on the low load cell portions of the map, unless you are running about 100+ octane.

This may be due to the quality and octane suggested in Japan.

What you really need is about - 10 degrees less timing in every cell of the map to get the most efficient driveability and fuel economy as well as torque out of the SR 20det

Not 41 degrees of timing but 21 degrees of timing...dead serious
