Hello all, Just after a little help from the Z fraternity. I have a 1991 nissan 300zx twin turbo. (import) I am preparing it for tarmac rally, (unmodified class) ... A tuner recommended a daughterboard from NISTUNE as a solutions to the following issues i must resolve... 1. doing away with the speed limiter. 2. tuning to return the car to full (original/factory) power. 3. Once installed the car must comply with CAMS ECU unmodified class rules (**** see CAMS Regs below) So that leaves me with a few questions... 1. Am i going about this the right way? 2. Do NISTUNE'S boards fills the previous requirements. (i have asked them, awaiting reply) 3. Do i need to purchase anything else for the tuner to be able to install and solve my issues? thanks for your time, everyone i appreciate it. Strangeknockers NOTE: technical regs CAMS manual - group M2 '(iii) Engine management For all automobiles, sensors and actuator on the input side must be standard, as must their function. The rev-limiter is free and a device having only this function may be added. The wiring loom to the electronic control unit may be modified within the last 100mm of the plug for the sole purpose of modifying/replacing the ECU. The wiring loom to the ECU and its terminating plug are to remain unmodified and a patch lead may be used to enable connection to the replacement ECU. Provision must be made to remove any piggyback or new unit and replacing with the original unit without rewiring. Outputs from the electronic unit must retain their original functions in accordance with the homologation form/ manufacturers specifications.
