Suzuki Jimny Nomad AT: Blitz Tuning ECU Brings a Bit More Power and a Higher Limiter
Blitz
Blitz now offers its Tuning ECU reflash for the JC74W Jimny Nomad automatic, adding about 6.9 hp and 8.2 Nm and lifting the speed limiter to 220 km/h. The job costs 55,000 yen in Japan.
Japanese tuner Blitz has expanded its Tuning ECU range and added support for the Suzuki Jimny Nomad with an automatic gearbox. The product covers the JC74W, on sale since April 2025, and the reflash costs 55,000 yen including tax in Japan. It isn't an external add-on box but a rewrite of the factory computer.
The original ECU is pulled from the car and sent to Blitz, which writes its own settings onto it. That keeps the factory functions and part of the stock safety logic intact while reshaping how the engine responds. For the Jimny Nomad AT the program bundles several changes at once. The speed limiter climbs from 180 to 220 km/h, and on cars with cruise control its ceiling rises from 100 to 130 km/h. For the driver this is less about chasing a top speed and more about the car feeling freer out on the open road.
Blitz also revises the throttle, fuel, air-fuel, ignition, valve-timing and torque-control maps. On the measured runs the gain works out to about 6.9 hp at peak power and 8.2 Nm at peak torque. The figures are modest, but on a naturally aspirated compact off-roader even a tune like this can noticeably wake up the response. The map isn't meant only for fully stock cars with the factory air filter and standard exhaust.
Cars fitted with the Blitz core-type air filter and NUR-SPEC exhaust systems are supported too. That matters for owners who have already started modifying their Jimny Nomad but don't want to end up with a random set of mismatched parts.
There are some mandatory conditions as well. After the Tuning ECU is installed, the car must run on high-octane fuel, and the spark plugs need to be swapped for a heat-range 7 equivalent. Blitz also warns that if the car carries third-party parts, the ready-made tune may not match the actual configuration.
For the Jimny Nomad this reflash reads less like an attempt to turn a utilitarian off-roader into a sports car and more like a careful bit of character tuning. The model stays a practical, ladder-frame Suzuki, but gains a slightly sharper response, a wider speed limit and a map built for the specific automatic version.
Earlier, 32CARS.RU reported that Suzuki will look into launching autonomous electric mini-shuttles in India.
