I'm talking about the fuel injection system, particularly pin point the fuel regulator. I have no idea whether the IAFM itself has any difference. What I'm sure about is the design of fuel rail between IAFM and IAFM+ is entirely different.

No info regarding sensor control fuel regulator on IAFM+. But it's a confirmed there isn't vacuum tube to actuates the fuel regulator on all FLX. As for BLM, the fuel regulator required vacuum suction from intake manifold to justify how much air getting in, at atmosphere 0 pressure(no suction a.k.a WOT), actuator will be fully penetrated and fuel regulator is in full force operation. Refer BLM intake photo, the fuel regulator is located behind the rocker cover, on top of IAFM near driver side between brake servo and rocker cover.



Whereas, in IAFM+, the fuel regulator already built in. Fuel line are directly plugged in. Due to less vacuum operation actuator, intake pressure is much higher compare to IAFM(FL,BLM). Accuracy of vacuum suction are greatly improved since there isn't external actuator(多只香炉多只鬼). Due to this higher intake pressure by nature, the designed of catalyst are different between BLM(lower pressure tolerance). According to Yau Yip Ah Wai, FLX needed 3 bolts, wider platform to hold the exhaust manifold, whereas BLM only need 2. I have no visual confirmation with FLX, but I conlanfirm BLM is only 2 bolts.


DbW signal is not lag, but the engine management is. Will need time to get used to it. Otherwise, do some cheap mod can improve it, provided you're into DIY. Gear oil, ofcourse will have difference, cause all of them using different gear box. All you need to do is read the spec plate by the B pillar at driver door side, you'll know what oil to be used. For me, mine is manual transmission, I don't really give a f*** as long it's not LSD/AT/CVT oil. Refer to my earlier comment, old FL/BLM uses Automatic Transmission fluid, whereas FLX uses CVT fluid.

What year is your BiBa? Spec? If you plan to sell anything higher then Mudah.My, then you need to pelanpelantunggu.com.my. Consumer are not that dumb to buy a car without looking at Mudah.My nowadays. Due to my crappy job nature, I'm widely involved in used car dealing business(despite I don't earn shit from it), if you're interested can PM me. I shall rekomen you to several used car dealer and negotiate for best deal(within KL/Selangor region only).

Don't forget, trade in a car and try to get a new car from those dealers, they also sublet to used car dealer and earn you 1 hand. Hence, those so called 超 high trade in value new car dealer is usually buying back your used car at much less compare to normal used car dealer. U sendiri fikir baik²
Brake pad kasi tukak. On the other hand, check whether the washer plate is still there, if you have recently replaced new pad, could be magician omitted the washer plate.
