I decided that I'd finally reinstall my keydiver chipped ecu and 750 cc injectors. Before hand I was running a stock ecu and stock injectors, stock maf, 14 lbs of boost, 3-inch exhaust, stock engine, big fmic, and that's about it. I'd see knock all over the place, any rpm and load range. But the car ran pretty good and was pretty fast. I put the keydiver stuff in and the bigger injectors and I turned up the boost to 18 psi. That's all I changed. My knock count is practically non existent now. Is that just because of more fuel? The fuel trims are now 81% low, 100% mid, and 82% high. The other question I'm having relates to turbo response now. The car seems to almost be on a switch. There is a moment where it seems to load up, almost bog, but not quite. It will pop once or twice through the exhaust, and then it takes off like a rocket. Almost as if it flicks a switch. I don't really know how else to explain it. I drove for about sixty miles tonight trying to let the ecu learn. Was that not enough? Most of the miles were highway miles. A few other notes here, 37 psi fuel pressure, b16g, 2g exh mani (self-ported), recirc'd bov, tps is adjusted correctly, 5 degrees base timing, 255 walbro rewired, afpr, stock fuel lines, kinda long i/c piping 2.25", no safc, or other fuel control. I think I probably need one of those. Thanks guys.
