I have a tintop zuk that lives offroad except for gas and food runs, with a welded rear and 29 inch micro swampers she'll attempt anything without breaking (usually). The problem is I have run out of spare carbs due to jumping, drowning and a couple tip overs on the side(circle tracking with 3 shocks that broke from serious air). My samuri has a strong block but it runs like shiznac due to the crappy samuri carbs. I know from VW's Webers aren't for serious offroad unless you spend a a lot of money so I have recently stripped a sidekick that had a crank failure of it's head,ECM, and wiring. I've found the wiring diagram online but I am still puzzled over the VSS deal with the speedo, I have the sidekick instrument cluster but haven't torn into it yet cause I just recently stripped the kick a couple days ago and haven't had the time yet. Can anyone help me with what needs to be done to put the VSS on the samuri speedo or use the kick speedo? A detailed E-mail from some one who has successfully completed the conversion would be appreciated. What does the VSS tell the fuel injection in relation to mixture and why do I need it, I thought fuel injection works off engine timing, temp, airflow, rpm- why is vehicle speed required. Much appreciation to those who reply. Thanks for your time. Remeber the Zuk is not a 4x4 but a street legal ATV.
