Stage 2 must use 95 octane premium fuel at a minimum with 98 octane offering better throttle response. (keep rpm up, use low gears, don't lug engine, stay below 50% throttle But users can use 91 octane in an emergency and follow safe engine driving habits with the fuel. Stage 1 is a premium fuel 95 octane tuning. A well flowing exhaust both works better for power and just as importantly retains less heat around the bike and engine compartment. However, it is recommended to have either a cat delete or free flow muffler with the stage 2. ![]() Stock, Cat delete, free flow muffler etc in any combination. The dynamic tuning of the ecu allows the user the use of whatever exhaust configuration. And you cant run stage 2 tuning without the proper air inlet modifications. IE: You can't run stage 2 airbox modifications with stage 1 ecu tuning. It is imperative that stage 1 or stage 2 tuning along with specific air box or inlet modification never be mixed up or used beyond their intended development. revised knock sensor logic (allowed by special tuning, cooler engine temp and air temps) decreased engine safety limiting (allowed by cooler engine temps and air temps) lower cooling fan temperatures keep engine in a happier state. (we need the airbox lid for modification to suit stage 2) This works for both power production and detonation prevention. remapped torque limiting logic, temperature limiting logic, timing and knock limiting logic remapped fuel, throttle, ignition timing, limits and thresholds for AFR, Exhaust temperatures ![]() The ecu mapping for stage 2 is much different: Increased power output from 7000-8800 rpm. Stage 2 adds more power from off idle to redline over the stage 1. Must use a minimum of 95 premium fuel at all times is where everything is optimized.Itsa little louder overall. Cable is stage 1 only and Electric can be Stage 2 ![]() Stage 2: ( ETB only- Ryker 900, 998cc, 1330cc)Įasiest way to tell if its possible to do stage 2 is to see if the throttle is electric or cable. must use at least 95 premium fuel (can use 91 in an emergency if ridden gently) All around better performance/response with improved limit setting (RPM, fan temp setting etc). A budget priced improvement over any stock setup. is for anyone looking for great value improvements for minimal outlay. Place your order( add year/model in notes at checkout ), send your ECU in with your order/ contact details and we will reprogram it and get it back out to you within 48hrs. We have 2 levels of ECU tunes for the Spyder/Ryker We’ve teamed with Monster EFI from Canada that have developed the tunes for Australian conditions with 100’s of hours of testing.
