So this kinda sucks. I was supposed to be putting my turbo kit that I've been piecing together on my prelude this weekend but know I don't think I'll make the dead line. I installed the 450's this weekendand it all sealed perfect no fuel leaks. I set the SAFC II to: 800 -40 1400 -39 2000 -38 2600 -37 3200 -36 3800 -36 4400 -36 5000 -36 5600 -36 6200 -36 7000 -36 The H23 has 240cc injectors just like almost every other honda so these settings should have got me close to good readings. The car is stock except for CAI. On the PLX m300 the car was idiling at 16.**. I had to turn the fuel up to around -33% at idle to get the wideband to read stoich. I let the car run for a while at these settings and smelled the exhaust didn't look or smell rich. I was still not happy with what the readings were telling me since I had to richen it up so much and the math does not add up here so I cut the car off and put the original injectors back in. Switched files so I was at 0 correctio and cranked the car again and the wb read stoich at idle and all the right readings when I got on the gas so I don't think that the WB is off calibration. The injectors look like any other 240cc honda injectors I've ever seen and the dsm's are blue tops so I'm sure they are 450's. Any ideas why it needed so much fuel.
