Re: ITB Conversion on 16 valve 4AGE On my stock bigport AW11 a leaking exhaust manifold gasket brought on the O2 sensor to read lean and it pumped gasoline in to the motor. Gas overall economy plummeted till I sorted it out.
Must it sit within the throttle opener bolt at idle? Also, While using the engine off, i could convert the accelerator cable bracket backward, This might shut the butterflyies somewhat more. Ought to i regulate the throttle opener screw to fix this?
This Regulate approach reqires that all 4 throttles be totally shut when about the stops. The throttle by-pass screws are manufacturing facility altered and set to equilibrium the throttles.
Merging The 2 harnesses may match, however , you've still bought 30-yr outdated crispy wiring and failing connectors to manage. Dr. Tweak makes brand new harnesses for swaps:
Ought to i alter the mechanical linkage? ( they look like get the job done simultaneous ). I also recognized after i well balanced the four cylinders to exact same air ingestion sum, a couple of of these will maximize or reduce the air ingestion quantity by them selves, it helps make me perplexed. Are you aware wherever i can see The 2 strategies of balancing the ITB?
Without the VVT operational there needs to be an important decline in the mid assortment energy. If there isn’t a apparent reduction then it’s hugely very likely the VVT pulley is no more useful and desires alternative.
buyer need to determine all the fitments or mods (because we dont give any immediate fitment or product) Marketed
seeking to stay clear of that on this motor vehicle given that i ought to have what I want just need to have wiring facts which i hope i found last night time. if my harness wasn't Slash from japan none of This may even be a problem...
Unfortunately, it states the HKS ECUs can only be tuned by sellers, so i can do practically nothing with the HKS ECU, it came Together with the motor vehicle from Japan because i acquired 4AGE Blacktop For Sale the car.
previous but not minimum You can find the screw on the frontal experience from the ITB and that is the adjuster to own air bypass the throttle plate even if closed (I've that completly closed)
The VVT solenoid is additionally obvious because the cylindrical component struggling with outwards on the right hand facet (exhaust side) with the engine. The two pin connector is unplugged and on the end on the solenoid experiencing upwards.
Or else you'll need so as to add additional wires on the 4a/7a harness. Until you can get the Blacktop harness and ECU Using the engine. Which is really the only real way this swap need to be done in any case
But I do not learn how to equilibrium the ITB's and hope someone on this forum does. Within the BT manual suggests only that you've to employ a carburetor balancer but would not say which sort or how To achieve this.
For that high idle, It is Nearly guarenteed you might have an consumption leak somewhere. Now if an individual had tampered With all the ITBs before you decide to it might be attainable they modified the idle up but ensure you eradicate any likelihood of consumption leaks and also other troubles before you decide to try and change the idle by way of the ITBs. The ISC is another area to look for leaks and or malfunctions.
