![]() ![]() Especially when that gain can be just as easily lost by a couple of mashes on the accelerator pedal.The DiskPulse GUI application provides the user with the ability to start/stop disk change monitoring operations, review detected file system changes and export reports. Personally I don't think the time and effort would be worth the potential gains, which would be only minimally better than a good 15.2:1 tune. You could do this with an external micro, but again its probably easier to do within the ECU using the 2.0 ROM configuration. So you effectively need to work out just exactly when you need torque and not. ![]() You do need to be a bit careful about this though, because very light throttle is where you will notice any poor running and torque drop the most. You might be able to do it better than I did by using the TPS / Load delta values to switch in and out of lean mode. Running leaner than 15.2:1 drops off torque, so requires more throttle, which negates any benefit in running lean in the first place. Having the engine respond very well to light throttle changes has the benefit of making the car fast, as well as (if you can be precise with your throttle) economical. This allows the car to stay in closed loop and minimises throttle and load based enrichment. ![]() I learn't that the secret to good fuel economy is throttle control. A cyclical improvement up to the point where I could easily get 600+ km out of a tank without worrying about whether I was running close to emtpy. The better I got my tune, the more responsive the car was to small throttle changes, the better I got at throttle control, the better my fuel economy got. (Note, I permanently ran 15.2:1 closed loop) That said, the more I played with the tuning on mine, the less I actually used map switching. It is fairly easy to setup the maps so that you can run one set for normal operation then use whatever values you want to switch to open loop with lean AFRs. Things like this were the reason I did 8 possible map combinations in the KSMods 2.0 ROM. ![]()
