hehe... noob?? wej already play standalone while i'm just no nothing about turbo engine.... hahaha.. quite a lot of question i'm asking him bout engine last 5-6years ago .... :)wej a noob? naahhhh, i dont believe it..
I sugguest you give Viswork Auto Lab a call they are sole distributor for Unichip I just wonder why you no need the turbo module. Maybe they can answer yr question.minormod said:Hi all,
I recently installed a turbo kit on my Altis 1.6 G9 model.
The kit is ordered from TurboSpecialties comes with a Garrett GT20 turbine, pre-assembled manifold, piping, extra 2 fuel injectors.
The installer tuned it with a Unichip Q+ (no turbo module) to control the extra 2 injectors during boost. The setup is currently boosting at 0.5 bar.
This is how the engine bay looks like.
However, whenever I step hard on the throttle and the engine revs and turbo boosts up, engine knocking happened (rattling sound). I've already used RON97 petrol and changed to colder spark plugs, tweaked up the AFR, the tuner has retuned it many times and even tried retarded the ignition timing.
Does anyone know how to solve this problem? Is it because there is still not enough petrol injection or what? Do I need to install a boost solenoid/controller? Thanks for any advice!
Thanks for all the input guys... Really appreciate it, I'm back at the place where they installed my kit. The boost comes in at about 2.2k rpm, and reaches full boost at about slightly more than 3k. The additional injectors run in so long as there is boost (> 0 bar). The tuner is going to retard the timing at peak torque according to him now... Let's see what happens, but the other time he tried retarding it make the car really unresponsive, i don't know how is he going to tune it again this time.at what RPM do you start seeing boost? and at what RPM does the additional injectors start working (as tuned by tuner)
answer these 2 questions and you may be able to pin point the solution.
i'm sure that its nothing to do with fueling, since you say there's no pinging at full boost.
Thanks man, I hope so too. Actually I also realised the kit is not really meant for 1.6 3ZZ-FE, it's meant for 1.8 1ZZ-FE engine. =/Generally, have to retuned (retard) ignition timing, use thicker head gasket, or low comp pistons. Since you said it is a turbokit, and only 0.5 bar, the low comp pistons option is out. Since you said if is a turbokit, I would advise you to take it back to the place that you bought it. It means that the setup/tuning hasn't been done properly and they have to fix ti for you or refund your money. Because the word "turbokit" means a tested, proven, reliable method of installing a low boost turbo to stock engine. Something that a seller/manufacturer already research on and it is meant to work on the engine it was meant for.
What is you AFR? I wouldn't think that enriching your fuel further will be a god option if the mixture is already healthy. Because a good low boost turbo is meant to improve fuel economy as well and can run lean on certain conditions.
Hope you settle it soon bro...
Hi AE101, nope I did not, because they say according to those who installed before the fuel pressure is more than enough for 0.5 bar of boosting.Hi Minormod,
Have you upgraded yr fuel pump ?
Did you install fuel pressure regulator ?
From my knowledge, normal pump & regulator cannot perform well at high end.. particularly since you have a turbo !
