VAG的EA888名機來到第三代,以縮短排氣頭段(減少渦輪遲滯)和採用ECU Open Loop設計來控制全區域的空燃比造就七代GTI有不俗的油耗表現,透過可變油量的機油泵浦這類新科技輔助下,提昇到220hp/35.68kgm的動力,搭配DSG自手排變速箱,0-100km/h加速能進到6.5秒。 隨著GTI在性能鋼砲等級中逐漸變成改裝主流,而監控嚴謹的Siemens也被台灣CPA品牌的ECU破解原廠程式後,成功拉大感知器的容許值範圍,就像這台GTI MK7在保持原廠引擎本體、電子排氣洩壓閥和節氣門的狀態下,能承受2 bar的渦輪高增壓(已換成CPA 400加大渦輪,處於容許的安全範圍內,而極限值為2.5 bar),即便換上全段直通的Down Pipe排氣管,含氧感知器仍然持續回饋訊號給ECU當作噴油量和進氣量的參數,也不會在儀錶內亮故障燈。 為了不讓DSG變速箱內的離合器打滑,多加2倍數的離合器片來提高接合力就能解決問題,但要防止過熱造成鎖檔的困擾,破解變速箱程式碼是最具挑戰的一環,同時也是把增壓值下修的其中原因。在反複的逆修正下,成功發揮100-200km/h的7.54秒加速時間,原廠的250km/h限速也被解除,在美國Dynojet馬力機下測出300km/h的極速。不過為了更貼近真實的情況,在馬力機設定成負載狀態模擬爬坡,也設定送風機的出風量來模擬風阻,因為車子在較重的負載下需要更多的動力,若把空燃比的設定太高反而會沒力,藉此找出最佳空燃比的平均值,才不會在半路中突然熄火。 文章連結(上/下):https://carnews.com/article/info/9c4709ad-a0ff-11e8-a9e3-42010af00004/
VAG's EA888 machine came to the third generation to shorten the exhaust section (reduce turbo lag) and use the ECU Open Loop design to control the air-fuel ratio of the entire area to create a seven-generation GTI with good fuel consumption performance, through variable oil With the help of new technology such as oil pumping, it can be upgraded to 220hp/35.68kgm, with DSG self-propelled gearbox, and 0-100km/h acceleration can reach 6.5 seconds. As GTI gradually became the mainstream of the performance in the performance steel gun level, and the rigorously monitored Siemens was also cracked by the Taiwan CPA brand ECU, the range of allowable values of the sensor was successfully increased, just like this GTI MK7 is maintained. In the state of the original engine body, electronic exhaust pressure relief valve and throttle, it can withstand 2 bar turbine high pressure (has been replaced by CPA 400 to increase the turbine, within the allowable safety range, and the limit is 2.5 bar ) Even if the Down Pipe exhaust pipe is replaced with a full section, the oxygen sensor will continue to feed back the signal to the ECU as a parameter for fuel injection and intake air, and will not light the fault light inside the meter. In order to prevent the clutch in the DSG gearbox from slipping, adding 2 times the clutch plate to improve the joint force can solve the problem. However, to prevent the overheating from causing the lock file, cracking the gearbox code is the most challenging part. The reason for the repair of the boost value. Under the repeated inverse correction, the acceleration time of 7.54 seconds of 100-200km/h was successfully achieved, and the original 250km/h speed limit was also released. The maximum speed of 300km/h was measured under the American Dynojet horsepower machine. However, in order to be closer to the real situation, the horsepower machine is set to load state to simulate the climbing, and the air volume of the blower is also set to simulate the wind resistance, because the car needs more power under the heavier load, if the air-fuel ratio is set too High will not be able to find the average of the best air-fuel ratio, so that it will not suddenly turn off in the middle of the road.
