Im having a difficult time starting the engine during cold start. It just rev up to 2.5k rpm and goes all the way down and dies. The only way i can stop this is to control the throttle so that it will drop at 1k rpm, whch is stable. Its very annoying to do this every morning.
Another issue is, when i rev more than 2k rpm and goes to free gear, its will again go all the way down and dies. What i have to do is to let my gear goes down to 1k, before i switch to neutral.
On operating temperature aka hot engine, its not as bad as cold start, but after high rev, it will drop to 500 rpm and goes back up again to stable idling. Operating temperature as in 30-40% of the gauge.
I tried to remove ISCV, it worked fine, but sometimes the idling will rise up slowly. e.g. from 1.2 - 1.4k rpm. Then i had to plug back the iscv in order to get a good idling (thats when in operating temp).
As i am told, at cold start we tend to have higher idling until operating temp., then the idle will drop, right? For my case, its the other way round. e.g. Cold start at 800-900rpm, hot engine 1000-1100rpm.
This was my setup before i had such problem;
AE101 4AGZE MAP
440cc 7M Injectors
E-manage Blue
SC14 Charger
Top Mount IC
Oversized pulley
Adjustable fuel regulator
Boosting over 1.1 - 1.2bar
This is my setup now;
FMIC using Vr4 IC
Bigport NA camshafts
Rebuild the vacuum lines (thanks to Shubert)
My boost did drop to 0.9 (max), this is caused by FMIC? Do i get power loss from boost drop? I cud easily go over 1bar at first gear before i FMIC. And the fuel consumption is higher compare to the setup before. Difference by 50km.
Anyway, i hope you guys understand what im trying to ask here. Any advice given here is very much appreciated.
