Peterfook Posted August 1, 2015 Report Share Posted August 1, 2015 My ride is evo 1 and i built it actually mainly for daily driven. When come into choosing management, i get the link g4+ plug in hope to get everything going fine including aircond since like i mentioned just now, i built it for daily driven also. Along the way of installing process and dyno tuning process, everything running well except 2 problem really don't know how to solve.1.) Aircond problem, the problem is that, when i turn on the aircond, the isv or iavc or choke keep on bounce my rpm between 1000-3000 rpm, even i adjusted it (actually not really know the exact way to adjust) , the frequency and i put the number as 0, it still keep on working and bounce my rpm. The isv or choke is a new unit and it works fine with my oem ecu. Worst thing is , even i off my aircond pclink, the rpm still keep on bouncing. I wonder how this can happen, is it because of CAN problem since my car is old and so does the wiring?2.) RPM limit,this problem is quite nonsense i face since i am in this motorsport hobby. I already off the boost control in pclink and also the advance rpm limiter. The map and RPM limit are all set according to ECT. RPM limiter is set at 7200rpm at desire ECT .And i have an electronic boost controller to control boost. At low boost 1 bar or about 15 psi, the car run well at rpm cut and limit at 7200 rpm, when high boost at 25 psi, the car suddenly do not have any RPM limiter and we (tuner and i) over rev the car till 9000rpm and we are shocked. and we try again, same thing happen, switch back to low boost 1 bar, everything is fine. I wonder what cause this, the only thing we done before high boost is re adjust the map limiter from 235kpa to 300kpa (so it allow us to boost over 1.35 bar) ..Really cant find any solution by ourselves and cant drive it safely and daily on street since no aircond (my country always rain) and no RPM limiter when high boost, seriously need help. I appreciate help from all people, Thank you and i attached my pclr file so you can take a look into what is wrong. evo 3 dyno 4 390 hp 447nm.pclr Quote Link to comment Share on other sites More sharing options...
