I have an Accel DFI 6.0 Seqential system 74060 that I purchased new in 1999. I am finally getting time (and money) to use it and cant get any info. I have tried contacting DFI in Wixom, MI and have only got the run around. Looking to use it on an 18* 421 SBC w/2 stage fogger (dry) utilizing fuel and NOS orifices on 1 injector w/glide. I also have a 74063 Wideband linear 6.0 unit w/Afset 1 software that I need info on its ability to interface with ECU or is it standalone only. I live in Davison,MI and am looking for anyone whom can be of assistance.
