Message: <blockquote data-quote="almostthere" data-source="post: 344557" data-attributes="member: 9519">1. Does your VR4 in a Wira feel a little laggish when you accelerate? When the accelerator pedals are pressed, does anyone experience an empty spot where the engine does not rev immediately. Very minimal.... ( this is on standstill and without any gears )- That's called turbo lag. Isit around 3500-400 rpm?2. Does improving the flow of your pipings allow for better idling?- Nope3. Does higher fuel pressure and increased injectors provide better idling? - Nope, such measures are for when your itching for high boost pressures and you don't want your engine to blow up after a few runs into the red line4. Will a fuel regulator provide better response to a VR4 engine?- NopeThis is based on my experience, but with an idling problem, most likely the AFM sensor is screwed especially when you start messing with rojak stuff. My mates Iswara VR4 cos he gatal to increase the performance of his car, swapped for Evo 3 stuff (wiring, ECU, sensors) and a 550cc injector (twin nozzle I think) and sometimes just died out. After that, at night idling was soo bad that the car was as if it had a low profile cam installed. Easiest way out for him was to install an SAFC and tune the proper correction in fuelling to solve it</blockquote>
