Some Advice Needed for my Dyno result
Car just went through 3.8 rebuild with high lift cam, long header runners, no CAT but considerable quiet tail section, COP, LFW, GT3 clutch and Ecumater EMU CLASSIC.
Wondering how can I smooth out the torque dip between the 3100 to 4200? The dip of the torque is at 300NM and it was my peak torque before the rebuild. The car behave like choking when I gave big or full throttle at low RPM below 2000 with above 2nd to 4th gear but it behave normal when just gave it small or reasonable throttle and choking disappear with gradual accelerate. We found the car behave less choking when we adjusted it leaner AFR at lower rpm. When car drive with high RPM and full throttle it behave like a rocket and none of this happen. So I think it is reflecting the dyno chart. So what can we do to smooth out the curve? Thanks Last edited by parkertseng; 12-05-2023 at 02:30 AM.. Reason: adding picture |

Need to see your fuel and ignition curves.
