Hello Folks around the globe, a newbie just logged on. Its my honor to start a topic of NA tuning for our QG engines. Hope can find more useful informations from the experts around.

First of all i introduce myself. Name is Leech... haha. Currently owning a N16 with QG16DE, auto. I already installed a full set of exhaust system (including extractor), drop in filter element, VS and Ignition system. I get a better acceleration after all the modifies. I'm currently stick to NA until the engine clocked at 80k km on odo. So any1 can share his NA tuning ?

got a QG15 in a B15, never did anything to it except change oil, it has e-throttle and that has lots and lots of lag, the engine performs well for a 1.5 and the economy is great.......no problems with the engine so far..........hope to keep it stock, but i might boost and tune it if i still have it in the next couple of years Laughing

Hey guys , just wan a second opinion ... How would it be if i replaced the QG16DE ECU with a QG18DE ECU and Emanage it ?? Will it be better than just Emanaging QG16DE ECU ... Coz i found out some1 in this forum mentioned that this modification is possible ... Thanks Smile

Hey Leech What extrators size piping you have on? and did you see any power gain when you installed them? Thinking about getting some for my QG1.6

Its 1.5" Internal Diameter nad 1.75" External ... Yeah just install the extractor alone definitely there's performance gain ... Don worry can just head down in exhaust shop then they have ready products for u to choose ... I think overseas exhaust shop do a better job then in Malaysia ... Confused

I saw 2.5" extractors for sale on tuner here. So i was wondering if to buy those. But someone told me that they are for the QG1.8 Engines so i am a little skeptical in getting those.

Leech, did u have your extractors made or did you buy it from an aftermarket company?

I bought it ... Its not stainless steel made but we have stainless steel extractor for QG engines in Malaysia ... Very Happy

^That's all nice and fine...but.....WHAT'S the POINT of putting a QG18 ecu in a QG16????

Adds rice hp?

If Leech already has a QG18 ECU and is thinking of putting it in a QG16 there is no problem in that.

Leech · Street 2NR Joined: 22 Mar 2008 Tech posts: 33 My 2NRide:

Yo folks , the point i am putting a QG18DE ECU because i have modified on the Intake and Exhaust , right now i am thinking of putting a bigger throttle body and port the intake manifold ... So i think i need a QG18DE ECU which mapS is different from QG16DE ECU to manage the new mods ... Don know if this would work or not ...

Just hope to get some infos , and yes my car has VTC ... Not CVTC !! Mine is driven by cable not E-throttle. Embarassed
