sigh..

this is what I was talking about. Study la bro. My 4G15 only had a cam pulley. Didn't use any ECU other than standard ECU. But that's because the overlap or lift is too much for the ecu to balance out. You'll need the piggyback or a standalone to manage the idling. But with a mild cam you don't have too much to worry about. And you don't need to upgrade your injectors la, you're not going full on high cams.

Seriously find another mech/tuner if this is what this guy is saying....

But again - back to my earlier question - why do you need the cam la? It doesn't do much if your engine is this stock. Maybe a small power gain here and there but SOHC just basically means you move the powerband around a little, not so much have massive gains. You want massive go for turbo
That was why bro. lsm and me talking about snails/siput......lol

hehe not really my place to say this, but i takut he mod and throw lots into the car, then realize, the gains dont really reflect. nanti paranoid xmau mod car liao. This kinda engine imo best left mostly stock.... light mods only....lightened bits here and there are fine (dont significantly buang weight off the flywheel or anything that extreme)

well known fact, the roi for na cars is already so low... and these simple BUT not simple enough engines are not exactly the platforms where the gains are that significant.

**just realized its a carb > efi conversion.... the carb would have been nice here
Carb mod weber can get more power......lol

In other words, let him burn?
let him gain the knowledge he want to have. he is curious to know what are the effects/gains/loss from his modifications. EInstein fails many times before his major success. same goes to jack ma

with permission, read this. @Latebloomer
Dont jump too fast.
nice article. The only thing i disagree with in here is the eManage and the standalone ECU choices. eManage doesn't support full open loop and the siemens VDO will overwrite it in a day. And since this was written in 2010, there has been a lot of newer standalone ECUs to choose from.

yea... in this case particularly... carbs would have made more power... and is probably more mod friendly if the purse strings xmau bukak besar
My mechanic and myself played around those days. The weber in the 3rd Gen Civic was fast. I did it to my 2nd Gen Accord face lift model, that one probably body weight heavy, improve slightly only......lol
