Upgrade forever with off-the-shelf OTS calibrations for most bolt-on modifications. You may need to lower the injector minimum pulse width value, or reduce the injector latency 14V offset to bring the latency down.Unlock power hidden within the vehicle by replacing conservative factory settings with more aggressive calibrations. There is a good chance that it may be bottoming out on the minimum injector pulse width value, or possibly even the injector latency. Once you have it cranking well, you can take the change from the fuel compensation table and use the change to multiply the cranking enrichment table and set the fuel compensation back to Example: if the fuel comp had to be set to 82 for good cranking, multiply the cranking enrichment table by. Try making adjustments in one direction or the other until you find the sweet spot. Set those cells to and try to crank the engine. It should be somewhere in the upper right hand corner.
Watch the tracers for the fuel compensation table to see where it runs during cranking. The actual injector pulse width during cranking does NOT match with what the ECU will log but can be verified with an oscilloscope. These tables vary from vehicle to vehicle, but they all have the same effect of setting a minimum pulse width during cranking. Just like the fuel compensation table above is adding fuel and below is taking fuel out. The cranking enrichment is very similar to the fuel compensation table. The end result is that the vehicle will run exactly the same, but you will have more room to raise the MAF table. This curve will get it into the ballpark, but it will still need a lot of work, especially in the low voltage areas idle, cranking.įor example, multiply the K value by 1. Increasing the values will increase the injector PW and decreasing them will decrease the injector PW at the given voltage. Tuning the table is very straight forward. Although the values in this table are raw no real world conversion they are directly related to grams per second of flow. The MAF table gives more precise adjustability, but it is not real time tunable so it takes longer to tune. Increasing the K will make it richer, decreasing the K will lean it out. Here is an example of an AFR test table used to tune the K fuel multiplier. This table should have the same value everywhere except for the cranking and idle area. There are a couple situations where you need to adjust the K value. The ECU will increase the injector pulse width based on the AFR target, fuel trims, other run time variable parameters, and environmental conditions.

How to Tune your Nissan/Infiniti ECU using Rom Raider and Nisprog/Kern (for only $10) Base fuel schedule is the theoretical pulse width that the ECU would have to run in order to maintain a This is NOT the actual injector pulse width.
Above is adding injector PW, and below is taking injector PW out. This table is only used when the vehicle is still in warm up stage. Fuel Compensation Cold is only used on some of the newer vehicles.
There are 2 types of fuel compensation tables to be aware of depending on what ROM you are working with. It should hit new targets with little to no tuning once the other fuel parameters are dialed in. Once the table is setup the way you want the car to run there should be no reason to adjust it again.

Q: Will i have any problems after a remap of my Nissan?Ī: If the vehicle in question is in acceptable condition then you shouldnt have any problems we will check fault code memory but it is not viable to check every component on the Nissan Ecu Remapping.Download Osiris User Guide. Nissan Chip Tuningīelow is our a list of Nissan’s current BHP & Torque Figures compared next to the improved BHP & Torque Figures of the Nissan, Contact Us for Nissan Ecu Remapping Nissan Ecu Remapping statistics Nissan 350z? Z33 We also have a 1000 BHP Rolling Road, so we can offer you to check previous and new BHP Torque Results and see what you gained. Some Older Nissan’s can not be remapped via the normal methods and need to special chip fitted in the ECU which takes a little longer, But has the same outcome. Please Note some of the figures below and for demostration purposes only, All Nissan’s are custom tuned to the customers needs & requirements, So Outcome may vary.
