![]() The workaround is to copy individual maps from the 60 rather than cloning the entire ECU. DF40/50/60a models have an ID chipped main harness so the ECU knows if it's mismatched, it throws a 4-1 error and goes into limp mode. Meanwhile it's also getting harder with Suzuki. One solution will be to use a custom programmable ECU (didn't they do that for a while with Sky Movie cards?) and that is under development. I guess not as much interest for ob's.Ĭurrently no tuner in the world has managed to crack security on Mercury ECU's. If this was a car there would almost certainly be a YouTube to explain how to re programme your ecu. I suspect you could prove it by unplugging MAF (if it has one). ![]() If outside of these ranges the alarm occurs. If weight an issue the Tohatsu (same motor different hood & tiller) comes in at 43kg and the Suzuki 44kg.ĭoes it have a MAF? The ecu could be looking for different values depending on whether this plate is there or not, so it could be a 15hp map and a 20hp map in the ECU with different acceptable ranges for MAF sensor. Regarding weight just be aware the Merc/Mariners are plated at 47.5kg despite the claimed 45kg. If the restrictor is removed, the computer controlled CDI will limit the engine RPM to 2800, the warning light will flash, and the warning horn will beep six times every five minutes.” The restrictor cannot be removed to gain more horsepower. “A restrictor in the air intake induction system restricts the amount of air that can enter the induction system. It is advised that you do pre-flash testing so you can determine the amount of change in fuel economy and speed that have been been achieved from your Nizpro Tune.Ĭheck fuel numbers (GPH) and speed at 3,000/4,000/5,000 and WOT before and after the Tune.That’s interesting, as Mercury reckon that the ECU triggers limp mode if the air intake restricter is removed from the 15. Depending on the HP you started with you may need to make bigger pitch changes to your prop to get closer to your target rev limit. Results can vary for every application due to differences in vessel weights, hull design, altitude, engine height, prop pitch and efficiency. If your boat is not reaching its full range of rpm at WOT beforehand of 6,000 - 6,200 rpms (This varies with load, temperature and altitude) before a Flash then you may have need of getting your boat dialed in after the Tune with the proper engine height adjustment and by using the correct prop with necessary cupping and pitch in order to achieve the most efficiency from it. ![]() To get the process started just add the correct Tune option to your cart and check out and then include your information in the box with your ECU.Īttention: Please Read prior to purchasing the Nizpro Powering Service and call if you have questions: A Nizpro Tune cannot compensate for a poorly running engine if there are other factors causing a loss of performance that need addressed first. This will not change your engine hours and factory rev limit remains the same at 6,200 rpm. NOTICE: You are not purchasing an ECU but but an ECU reprogramming service by sending your ECU in to us.
