| | holley efi tuning
I have a holley efi hp computer running a ls1 with ported heads, predator cam, and fast 90/90 setup and 36 lb injectors at 43.5 psi (which i think are 48.8 at 58 psi). Timing at idle was 25 degrees and 39 at wot. I had the car running with pump gas great during wot and crusing. I could not get it to stop surging at idle and believe that it was a vacuum leak and possibly fixed it. While it was down i switched to e85 and it crank up fine, surged a bit then evens out and idles at 1050 rpm. Once i rev it hangs the idle at 2100 rpm and the air/fuel sticks around 8.5? Anyone with experience with this system would be a great help im new to tuning efi and decided to learn the hard way and jump in.
Also i dont really know where the throttle blade should be set at, at idle. Should i use a feeler gauge and set it to something? thanks
