Re: ITB Conversion on 16 valve 4AGE On my stock bigport AW11 a leaking exhaust manifold gasket prompted the O2 sensor to go through lean and it pumped fuel in the motor. Gasoline economic system plummeted until I sorted it out.
Unplug stock harness from all engine-sensors and factors like injectors and distributor. Install dummy resistor-hundreds on ECU's injector wires to simulate injectors.
Quotation Postby billda » Sat Sep 13, 2014 one:32 pm Thanks a great deal in your aid, it would make things Significantly A great deal clearer now! I'll pull the TB out to complete the perform. I think i tousled the names with throttle quit screws and throttle opener screw, i seen which the linkage higher than the throttle opener does not sit around the throttle opener bolt at idle, I do think this would also cause the butterflies open, proper?
Even though equally engines feature a thick gasket/warmth insulator involving The pinnacle as well as inlet manifold the Blacktop and seemingly the afterwards Silvertop versions element a trapezoid Minimize-out in lieu of a square cut-out in provision with the gas path out of the injector.
Ought to i regulate the mechanical linkage? ( they appear like perform simultaneous ). I also found just after i balanced the 4 cylinders to exact air intake total, a couple of of them will maximize or decrease the air consumption quantity by by themselves, it helps make me bewildered. Do you know the place I am able to see the two processes of balancing the ITB?
The internal transition with the rear opening as noticed within the rear flange casting with the throttle housing differs. The Silvertops have an easy round machined opening at the same 43mm diameter with the blade / throttle center bore although the Blacktop has much more of a kidney condition to suit the several manifold (see “Inlet manifold”).
To allow for your Blacktop’s have to have for a vacuum sign (see “Load metering”) a bigger portion of metal was additional on reduced Component of the flange facial area of The top to mate in opposition to the inlet manifold. You should see underneath “Inlet manifolds” To learn more.
The remaining flywheel pictured is the sooner Silvertop design and style while the appropriate may be the lightened Blacktop.

They aren't interchangeable click here with no modifications for the wiring loom / harness. See out Workshop manual posting for the information on converting this Silvertop wiring loom / harness to generally be suitable having a Blacktop ECU.
The VVT solenoid is additionally seen given that the cylindrical section going through outwards on the ideal hand facet (exhaust facet) of your engine. The 2 pin connector is unplugged and on the top on the solenoid dealing with upwards.
Estimate Postby billda » Thu Sep eleven, 2014 twelve:27 pm Thank you Jondee86!! The vehicle arrived with all four throttle by-pass screws screwed every one of the way in, i made use of a carburetor balancer to determine if Just about every cylinder was sucking the same level of air, but Along with the 4 by-go screws all the way in, the No.
Insert to quote Only show this user #twenty five · Dec 4, 2007 You are doing must repin the ecu connectors, and There are many other modifications you have to make. When you are operating the Silvertop AT ecu, the ecu pinouts are Pretty much equivalent.
