Popcorn limiters are nothing new, they have been available on Land Rover Defenders for some time. The ‘Popcorn’Limiter tells your vehicle’s ECU to cut fuel to the engine at a set RPM (usually at around 4300rpm), the effect of cutting fuel will cause the engine to bounce off the rev limiter, the result is a diesel-powered vehicle that sounds more like a petrol engine. Previously a ‘Popcorn Limiter’ was only available on a Land Rover Defender TD5, however IRB Developments have developed a hard cut limiter for the Land Rover Defender 2.2 Tdci.
“They said it couldn’t be done, so we had to do it”:
We were told that popcorn limiters were only possible on Defender TD5, so we just wanted to prove that it could be done on a 2.2 tdci. IRB are currently playing with turbo setup and launch control of sorts to accompany the popcorn limiter.
