Kawasaki Z1000 ECU remap – lean running with an Akrapovic and 119bhp when it came in…

By 24th September 2014 ECU Remap, Kawasaki

We’ve remapped the ZX-10R, Z1000SX and ZZR1400 but this is the first new Z1000 we’ve had through the doors. At the moment we can’t switch the lambda off, but we get around that problem by giving it more fuel in the Manifold Air Pressure (MAP) table.

This engine started on the Dyno with 119bhp. By the time we’d finished it made 126bhp which is a worthwhile gain. In truth what the remap really did was add fuel to a really lean-running motor, especially with the Akrapovic pipe. These days if you match an open pipe to a stock setup – which is super-lean to get through emissions testing – you’re asking for trouble in the long run, with poor throttle response in the short term.

Stock ECUs work with a certain back pressure from the exhaust – dial out the back pressure with a can and the lambda and MAP map just won’t work properly…

A striking beast is the Kawasaki Z1000 – this one was running lean with an Akra' can. Nothing an ECU remap couldn't sort out.
