David K Posted August 27, 2007 Share Posted August 27, 2007 A few months ago i finally got the TWM TB on my zx and i cant for the life of me get the damn fuel delivery correct now. I removed the innards from the n/a AFM and put them in a turbo AFM. The engine is a p90 shaved and shimmed with flat pistons. Im adjusting fuel at idle, 2,500 rpm, and 4,500 rpm.I figured if i get the fuel mixture correct on all 3 of those engine speeds i should be good to go all the way up to 6k at least. I seriously cant get the damn mixture correct. Im thinking about sticking a colortune plug in each cylinder and checking combustion. Given what i know, it shouldnt be any different than tuning carbs with a colortune, correct me if im wrong. Quote Link to comment Share on other sites More sharing options...
S30TRBO Posted August 27, 2007 Share Posted August 27, 2007 David, Do you have a wide band O-2 in the mix? This might help you as well. Quote Link to comment Share on other sites More sharing options...

Damn this AFM, it should have been a simple adjustment. Quote Link to comment Share on other sites More sharing options...
