Subject: Re: EGR Delete for Dummies by mseven on 2011/4/11 15:15:21 All of EGR tables are zeroed out in the bin as well as turning the "switches" off that set codes. The same would apply to any AIR with the exception of changing the 02 add-on. When tuning several things change, getting the fuel and timing right controls detonation and or spark knock. When spark knock occurs it is not only a product of too little fuel but can sometimes occur from too much fuel (particularly in a map car). Where and how much timing is pulled is also controlled in the bin which are modified values. Once enough data is used to get the tune right, if encountering a weird load/rpm range typically the most timing I see being pulled is 1-3*. With SD/map cars it also important to note that it takes quite a bit more data to get the car tuned well. But the consistency level of fueling/timing/load values becomes excellent. IMO it can become a better tune than the maf cars due to the ability of having actual fuel and timing cells through-out the entire rpm vs load ranges. The SD bins are also more "hacked" (the ability for better tuning due to an increase in IAC controls, fueling in open, closed and pe etc.etc.)out than any of the maf bins. This is also one of the reason/s why it takes more work/time to develop the tune. |
