sert maps
after trying several maps on my race tuner I finally found one that seems to have the most power. I have the stage 2 103 kit with 255 cams, stock heads. 9.5:1 pistions. I am using the 205UH005-00 map for the exact set up. I didnt see it in the list when I first got sert and was using 103 kits with different head and cam configurations. for some reason it wasnt in with the rest of the 1690 programs and was way down the list with 1890 programs. the problem with the wrong head-cam set ups is that, even though the bore kit matched mine it caused different programs to have dead spots at different rpm's, some ran unbelievable bad. stage 2-3-4 maps with different cams than mine.
The 205UH005-00 am using now really makes the 255 cams pull from 2000-4000 rpm like I keep reading about in the forums. the only thing I dont like is how it starts. It seems to turn over slower than other programs and if I dont let it run for at least a minute it sputters and has stalled. then I have to push my manual acr;s back down, I tried turning up the timing 2 degrees from 700 rpm to 2000rpm it may have helped a bit. I have the afr set at 13.8 in lower rpm ranges. I bumped it the iac warmup setting a couple of points in the cold engine settings . none of these thing seems to have helped. any one have any ideas .

The ecm automatically sets your timing to 0 for cranking, no way to adjust. I would add or subtract fuel from your cranking fuel table at the different temps. Some bikes like less, some more, especially when hot. Add a little fuel to your warmup enrichment to see if that cures the cold stumble. The iac warm up steps are used to correct a flare or stumble in rpm's when your bike starts. Hope this helps.
