Haven't road tested yet, but should be nice going down long grades or coasting up to toll booths...assuming the PCM doesn't complain about injector flow.  |
Well, it did cut off fuel flow, and the truck would coast along just fine...with the engine rolling at about 500 rpms. But the engine ran rough with the switch "on"; it seems the wire length was causing issues. I might try wiring in 8 relays to a common on/off switch. But I have better fuel saving ideas to work on first...
