There is no need for me to remove my extra injector and my car is running smoothly. graph below explained everything. and tells between a good tuner and a maybe hmmmmmm.. not so good tuner :P lolz [ATTACH=full]621631[/ATTACH]Indeed, i was quite surprised after see the dyno after being tuned. It was 169HP on wheel. before that, my car was 143HP only. from the dyno chart the blue colour line shows the result before i dyno tuned. You can see that the previous tuner set the A/F ratio at low rev region is too rich while the high rev region is too lean. This is part of the reason why my car feel so heavy and always mati engine when i slow driving. And i feel like so lucky i didnt high rev too often, else my engine or might as well me myself gonna say bye bye to this world :-sthe green colour line shows the result after my engine has been fine tuned. We can clearly see the horsepower hv significant increment at high end rev region. A big gap result if compared with my previous tune. Actually you can see the power curve goes weird at region 4KRPM due to my original clutch slipped. and not smooth curve at higher RPM due to my engine have compression leak :(. The tuner told me that my engine power can be further up if to advance the ignition timing. but due to my internal are all stock he do not have 100% confidence to tune for me.like the previous tuner told me when he installed the turbo kit to my car, he will jz "cincai" tune the car for me. He is gonna kill the engine and me with the A/F ratio setup. And he also realize that my car have serious knocking at higher rev region and he retarded the timing so much that my car feel no power. As for the ignition coil burnt problem, my current tuner said is WAJA and EVO engine which use the e-manage all have this problem. And it can be solved by adding a device to the emanage and coil. Anyone have idea about this?very big thanks to d'tuning. i guess some of you might visit to this workshop before.. he is very skillful and very patient to answer you if you have any doubt on the engine problem</blockquote>
