that currently being mentioned in today and age, a programmable ECU is SO cheap that there truly isn't really Substantially point attempting to operate it over a inventory Personal computer.

This can be a guidebook for earning a educated comparison in between the 20V Silvertop and Blacktop engines with an outline of the real difference described. Some more compact differences usually are not lined and You will also find some variations in between the main and 2nd generation of Silvertop engines.

Whilst each engines feature a thick gasket/warmth insulator concerning The top along with the inlet manifold the Blacktop and apparently the later on Silvertop versions feature a trapezoid Slice-out as an alternative to a square Minimize-out in provision with the gasoline path out from the injector.

4AGE 20v ITB vacuum Recommendations on Intecracing.com The vacuum hoses would be the 2 U formed hoses, They may be connected into each other. This set-up may well not rely upon MAP, open up to correction

Be sure the dashpot under the ITBs is hooked to the proper vacuum resource normally it won't suck the piston in and will hold the idle higher. Be sure It is modified suitable so when vacuum actuates it the pin sucks in far enough for your throttles to relaxation on the challenging quit. As OST explained ensure that the many throttle plates are adjusted adequately.

Chances are it is just reacting on the inputs it is actually receiving. Exactly where is the WBO2 sensor Found ? In one of many header tubes or after the collector ?

Do not know in regards to ITBs, the O2 sensor is just actually alleged to alter the combination at cruise and the like. I'll Use a browse from the tech short article I have around the stock ecu and its functions when I get property and find out what it claims in regards to how much adjustment the O2 sensor is able to.

So basically what I am searching for is something which can utilize the inventory sensors (I is going to be working with map as well as a wideband), and is also now assembled. I am ok with being forced to do rewiring about the harness.

Add to estimate Only display this person #5 · Oct seven, 2007 Concidering the fact I can not weld whatsoever I will most likely not go the ITB route lol... Sounded like an awesome thought 30min back but from the setup the appropriate way is a great deal costlier than I assumed.

Estimate Postby billda » Wed Sep ten, 2014 twelve:19 pm Thanks guys for this Considerably facts. I am in Columbus Ohio, i have identified as several tuner retailers below and questioned if they're able to tune a HKS ECU over a JDM car, regrettably they cant. The O2 sensor is found beneath the motor vehicle and under the pasanger seat, so it is actually after the exhaust collector. I can listen to the ISCV sucking air once the motor vehicle is simply begun, the rpm raises slightly then drops down, but its not sucking air when idling, Thanks Jondee86 for that techniques of testing the iscv, i have browse your preceding posts about cleaning and screening iscv, and cleaned and examined mine a number of months back.

My 4age 20V is operating way also abundant and provides black smoke from the exhaust. What i also seen is often a vibration at three/4 throttle to WOT with about each RPM. Does not audio flywheel related imo, though I'd that difficulty on other autos and it sounded distinct.

The 4A-FE is different with the 4A-GE concerning efficiency and electrical power. While both of those have the exact same displacement and therefore are DOHC, they had been optimized for different utilizes. The initial clear big difference are classified as the valves, the engine's consumption and exhaust valves have been placed 22.3° aside (compared to fifty° from the G-Engines). The next is always that it utilized Toyota's Higher-Mecha Twin Cam procedure,[eighteen] exactly where each camshafts are geared together with a singular timing belt driving the exhaust camshaft as well as the exhaust camshaft drives the inlet camshaft by means of scissor gears (both equally camshafts to the G-Engine are pushed because of the timing belts rather).[20] Some of the less directly noticeable variances have been compact combustion chamber designs with greatly shrouded valves, significantly less aggressive camshaft profiles, a Forged crankshaft (rather website than a forged crankshaft during the 4A-GE), ports of a small cross sectional place, an extremely restrictive ingestion manifold with prolonged runners joined to a little displacement plenum and also other changes.

Additionally, it has better compression ratio, and reformulated combustion chambers to improve the gas economy and emissions. All variants applied belt-pushed SOHC eight-valve counter-circulation cylinder heads with only one downdraft carburetor.
