[QUOTE="Alchemis, post: 2105766, member: 20898"] okay... as you all know, my car is ready.... i got my datalogit i got my Wideband. let me show you all some pictures about tuning the engine. 1) use datalogit to do a map watch on your AFR in a 20x20 grid... it's something that outside dyno tuning folks unable to provide you that accurate. below is my log run. but as u know, still running in... thus i'm only tuning on the cruise side only. http://img406.imageshack.us/img406/4568/mapwatchlu9.jpg 2) take a sample 20x20 target AFR map... this is something that what you want your car's AFR to look like. this is my target. as you can see it's pretty lean on what i want to run.... according to my information googling and also rx7club.com our car can run safely on cruise of AFR 16.. but my balls not that big i set it to 14. http://img133.imageshack.us/img133/1129/targetafrrn3.jpg 3) the template allows calculation of what correction AFR we should plug into the INJ map after we re-cal base which reset the INJ map to all 1... less than 1 means lean up, more than 1 means richen up. below picture shows my correction map. there are some lean up and there are some richen up.. my idle now solid at 14.. very nice and clean smell in exhaust.. doesn't polute my house :P http://img406.imageshack.us/img406/5720/correctionjn5.jpg i'm yet to tune the boost area after i run in my car... slowly learn how to tune the IGL and IGT as well. hopefully this benefits our group of RE owners in future tuning of own car.
