Ryan Jerard Posted November 10, 2016 Report Share Posted November 10, 2016 I have a jza80 with 2jzgte, running a plugin G4+.I have just got it back from being tuned. Every time I decelerate using engine braking, when I disengage the clutch, it stalls. If I disengage the clutch directly after accelleration the idle control valve brings it back to idle nicely. It's like the ecu is seeing idle pos on the tps during overrun, and it's trying to achieve 900 rpm, but it can't achieve this while decelerating so the icv ends up being shut altogether, resulting in a stall once I depress the clutch. Im not an experienced tuner, but I would like to know how to solve this problem myself. Any help is much appreciated Ryan Quote Link to comment Share on other sites More sharing options...
Scott Posted November 10, 2016 Report Share Posted November 10, 2016 Hi Ryan,Probably the first step in resolving this would be to record a PCLog of the problem happening. This way we can look at what the ECU is doing. You can find out how to do this here:https://youtu.be/_P1LRANeO4AThere are multiple possible solutions depending on what the ECU is currently doing and if you are using open loop or closed loop control.Scott Quote Link to comment Share on other sites More sharing options...
