Often only one value is given for Latency, not the whole table.įor example. To change a value in the Latency table, select a value then press =, and enter the new value. The reason for the 2D table with different voltages, is it takes longer for the injector to open at lower voltages. Injector Latency or DeadTime, is the amount of time it takes for an injector to open after voltage has been applied to it. Then click InjectorScalingDSM and change it to InjectorScalingEvo. If you wish to use a value you get from a Evo site you need change the scaling. The Evos guys use a different Scaling then I use for the DSMs.įor example an EVO site will give the flow of stock 450s as 424, but DSM sites say 450.Īnother example is they give the Evo8 560cc flow as 513, but you would use 560 with a DSM. To change, press =, then enter the new value. Injector Scaling is the flow rate of the injector. I have some example settings at the bottom of the page. The best way is to find someone with the same injectors and copy their settings. The first step is find your Base Settings. If things are not perfect at idle the Front O2 Sensor will take over and fix it, that is why its there.īecause the fuel pump flow isn’t linear(flow rate changes with fuel pressure) and your fuel system may have restrictions at high flow rates, you are not going to get AFR to match perfectly in every cell.īut you can get close, so its within a 1/10 point or so. I’m of the first school of though, our Fuel Maps have a nice AFR scaling so why not use it to make tuning easier. That Fuel Trims should be perfect, and that AFR readings are going to be offset from the Fuel Map and not match up. That your AFR readings should match your Fuel Map, then get Fuel Trims as close as possible. There are two schools of thought on setting up your injectors:
