Speed and boat movement – try sitting in a boat, holding onto a laptop computer at 100 mph while dodging waves and other boats and you understand why a static dyno is so important. We are able to listen and monitor audible spark knock and monitor internal cylinder pressure by measuring cylinder pressure through multiple sensors on individual cylinders all at one time, thousands of times per second. On water testing in a boat with boat & engine noise make it nearly impossible to hear and very inaccurate.cĬompare this to the engine working under every possible load, rpm and temperature condition that are adjustable on the dyno.

They have a ecu flash that will make 300 plus hp.

Tuners will normally try and listen to the engine to hear for spark knock. If your going to do any performance mods on Yamaha motors Hydro-tec is the way to go. Nizpro has developed ECU Reflashes for the following YAMAHA OUTBOARDS L4 1.0L Offshore F50 F70 L4 1.8L Offshore F75 F130 L4 2.7L Offshore F150 Mech L4 2.8L Offshore F150 F200 V6 4.2L Offshore F225 F300 V8 5.3L Offshore F300 F350 L4 1.8L VMax SHO VF90 VF115 L4 2. You can only calibrate to the atmospheric conditions on that day. On the water, you do not have the range of input sensors available to provide real time results, which allow for adjustments and calibrations for climate including atmospheric pressure and temperature.

No need to re-rig your boat which costs $1,000s.

Improving throttle responsiveness.Īll NIZPRO tunes are first developed on our inhouse dyno cell and then we complete testing on the water. Increasing horsepower by improving fuel and timing maps. Its all true Testing: We have rigorously tested the Nizpro Marine 332HO ECU Flash on a standard Yamaha 200hp SHO engine utilizing the Nizpro Marine Endurance.

We do NOT tune to the limits of the engine, we optimise the existing performance, without impacting reliability.ĮCU Flashing is the process by whereby your outboard ECU can be re-programmed to in order to reach the maximum performance of the engine.Īn ECU Flash can help maximize your outboard engine performance by: When we started our Nizpro Supercharger program in the early 2000’s we choose Yamaha Outboards as we believe they are the best built outboard engine on the market, and we still do 10 years later.Īt no point do we attempt to push the engine to breaking point! (that would be a BAD business model!), and we wouldn’t be here all these years later! With a Nizpro ECU tune you can also expect your fuel economy and fuel efficiency improve.
