i think the ECU has a pre written codes to determine the air flow under normal conditions.. however, if there is more air flow compared to what the ECU understands, it will then screw up the readings. I think for this setup, ppl put this ECU to sleep and use a piggyback for this customised setup. Bros, please correct me if i am wrong.

from what i understand a few days back that the ECU determines the amount of fuel injection, but not the amount of air...
so my guess is that if there are more air going in, the ECU will then inject more fuel to burn. Pros can help clear our doubts?

hmm.. maybe the ECU determines the amount of fuel injection - but i tink, there is a sensor to reference that on the amount of air... when installing a turbo, there is a higher density of air that enters to create more power - then ecu need to be tuned?

u all are right
the ECU mapping always have limiter so as not to push the engine to extreme. so the amount of fuel inject is always to certain limit. if turbo charge is install, the fuel injection is not tune, the max power is not achieve. so ECU must tune for this changes.

Hmmm. I also agree the ECU may have a range of air flow input which will correalte to the amt of fuel injected into the engine. So, it points down to what is the maximum airflow the ECU is program to.
I guess so.
Another topic is if we have more air intake inlet, but the suction power remains the same. Will there be really more air into the system? Because more inlet, same suction power so that means less suction effect at both of the air inlet
Maybe really need the pros to comment

if you are referring to having better low end power, best is to have some form of air reservoir within.. this is to have readily available supply of air whenever u need it. if there is a reservoir inside, u will feel less lag of power when u change gears... anyway, imho, having more air intake inlet might not necessary mean more power.. u will need some form of force induction to 'force' the air inwards...

I thought Roy mentioned all RISK to be discuss in the separate RISK thread? Is his English too chim to understand? Or you all are just bo chup about what he said? Btw how about this, instead of single throttle, we increase to 4 throttles or so called the ITBK>> nozzs.com/index.php?main_page=product_info&cPath=5_11&products_id=23wow like trumpet.. hehe...

Most people will get piggyback to do the job, increase airflow definitely will have increase in fuel being inject in, with piggyback, you can have more air flow in and at the same time using the piggback to adjust the amount of fuel injecting in, can be kept at the minimum. That's how wonderful a piggyback is. Please do not start comparing QF with piggyback.

wow like trumpet.. hehe... Bro, this setup is superb la, heard someone in the Far North tried this on a Naza Suria aka Picanto, but the car cannot handle the increase torque this thing produced. Anyway, with our experts here in various workshops, I guess 1 day you will see a ITBK Picanto on the road. With this, there is no need for turbocharge already lol. Bro Elvin you wanna be the white mouse for this project? I know a garage doing this ITBK

wow for this setup surely need piggyback? but how is this setup different compared to turbo? being white mouse also need $$.. i dun mind to be white mouse if u sponsor me $$ la....

thanks bro eric for the information! Bro time to consider piggyback, there is only one until now most compatible for Picanto and yield good increase in performance of up to 25% on a N/A and 40% on a TC(depends on mods). Its the Unichip Q bro, I know someone in here mention about Unichip not suitable but he himself is not installing any so y give such comment. Anyway, it definitely works better and looking at the cost of installing and dyno tune at $350, hardware can find 2nd hand at $350-$400, btw its cheaper than even the full data log but have better results produced.

Definitely need piggyback my friend heard price is 3/4 that of turbocharge but result is about the same. The setup is just our normal N/A type of setup, just that there is additional throttles running across. Actual setup I not that sure cos the last time I saw is an EG6 doing this ITBK at the usual SMSA Supersprint, I was there doing the Sprint using my beloved Suzuki Swift GTi track car(export out liao sad...).

i heard alot of good stuffs of unichip verQ too... maybe in future will consider to install...
i had a friend who done a piggyback, original ECU is sleeping... when he send back to agent for servicing, i think they swing it back to the original ECU or something.. putting the piggyback to sleep.. his car got a sudden drop of torque and hp after the servicing... is it true that such thing will happen?

hmm not sure if ITBK is considered an illegal mod since it is not a turbo? it should be still a N.A. afterall right? lol
however, if they consider 'adversely affect the safety and exhaust emission characteristics of the vehicle', it may be illegal.. lol

That depends on who the tuner is, not to worry, I've known a top tuner here locally that tune thousands of car and yet till now no such problem, even big garages like D***technica, Garag**, Exot**Tun**'s cars also end day send to him to rectify, please do not have the misconception of big garages are always better, end day see who tune, rather have a different day different tuner or just 1 tuner? When you are interested you let me know I bring you to him, I'm doing mine in near future. Gonna do somemore mods before I do my final tuning. Hope to see an increase to 75 or more horses for n/a. Btw the ITBK is confirm illegal haha. Track car use ok.

speaking of piggyback module, which is more suitable for pica, Unichip Q or eManage?
