EBL Flash has the ability to auto tune or VE Learn. There should be information from Dynamic EFI on how to use the VE Learn. Most members here at gearhead-efi use TunerPro RT to tune with.

Thanks for the reply .. i know how to use the ve learn feature i need help with the following idle, acceleration enrichment and getting rid of some spark knock around 2000 rpm....my idle is a bit rich i can smell it at a light....as far AE i get hesitaion on a throttle stomp from a stop and cant break the tires loose...on my spark knock it shows up when the engine is up to temp 195t around 1800-2300 rpm 50-70 kpa happend on the highway steady throttle and tip in....also also from a stop if i kind of get on it i get spark knock in the same area.....do you think im running enough fuel pressure ...should i invest in a vacuum reference fuel pressure regulator i need guidance

Get a fuel pressure transducer and log, same with WB if you don't alreaady. Mr Rausher is an excellent resource.
