Malfunctions, engine repair
ECOTEC F18D4 engine is a continuation of F18D3, a copy of Opel’s A18XER and at the same time enlarged F16D4, along with its pros and cons. But unlike its younger brother, the 1.8-liter engine has a variable geometry receiver. In time, it was also applied on 1.6 liters and accelerated the engine up to 124 forces (on Cruze SW it is used).
Motor resource of F18D4 engine is not big, a little more than 200 thousand kilometers and strongly depends on operation. Otherwise, it is a typical representative of Chevrolet ECOTEC D4 family, unlike the younger models, it is powerful enough, moderately economical and the car with it goes decently. When buying a Chevrolet Cruze or Opel Mokka, you can safely take them with this motor.
Tuning the engine Chevrolet F18D4
All those methods of modification to increase power applied to F16D4, apply to our 1.8 liter engine. To the indicated figures of power increase on 1.6 liter engine, we can safely add 12-15% due to the larger volume. Further we will talk about F16D4, as an example.
Chip tuning
In the market you can meet a lot of tuning studio, which one chip will launch the car into space, it is certainly an exaggeration, but some gain is quite possible, to pile put exhaust spider 4-2-1, thereby removing the catalytic converter, receiver, firmware under this case and will be a completely different song, about 125-130 hp we will get without special tricks.
Turbine
Above was described the most optimal complex for refinement of the motor, fast, simple and reliable. If you have nowhere to spend money and want to create something unusual, you need to build a turbo.
Here is a short list of necessary:
– TD-04 turbine + custom turbo manifold.
– autobahn88 intercooler (or similar)
– Audi TT RS bypass
– zero vic + cold intake
– modified intake manifold
– oil trap D1- spec
– NGK IFR7X7G iridium-platinum plugs
– fuel pump FPP 340 l/h
– fuel rail on the second row of injectors
– second row of injectors Bosch 235 cc
– custom fuel module
– Hardline anodized fuel pipes
– nylon braided reinforced hoses
– FOR fittings
– BlackRock fuel regulator
– Radium pressure gauge
– engine oil LIQUI MOLY 5w-30 dexos1+ oil stabilizer Lucas oil
– AUTOOL X50 plus auto scanner
– broadband lambda probe INNOVATE 3877 LC-2
– EGT sensor DEPO
– DEPO boost sensor
– ECU subcomputer – Ecu master DET 3+
– AEM V 2 water-methanol system
– custom exhaust on 63 mm pipe
– custom expansion tank
– right engine hydraulic support
– cold thermostat for 92 degrees in aluminum housing
The components are given as an example, you can use others. All this will allow you to get in the neighborhood of 200 hp at 0.7 baz excess at 100 gasoline.
To install the turbine you need a bypass, not a block-off, as we have a MAF, with a block-off will not work properly.
It is necessary to use 2 rows of injectors, our intake manifold has holes for the second row (and for this we need a separate control unit for these injectors – ECU MASTER DET3+). Our native fuel pump handled 2 rows of injectors and very well! The standard Aveo pump has good performance and it is enough for such tasks.
We also need AEM water-methanol injection: we put a 500 cc injector, use 50/50 alcohol/water.
The mixture at peak at 0.7-0.8 bar should be 10-10.5/1. At 11.5, the EGT rises sharply. A 61mm minimum straight-through exhaust, a good thick intercooler and a cold intake are also required.
Must install a cold thermostat and use Lucas oil stabilizers and oil only with dexos1 approval for turbo engines.
Also, will pop up an error on the automatic transmission at a boost greater than 0.5 bar (Check and abs, error -84, power limitation)
It should be removed in the main firmware and change the torque limitation on the gears, as the maximum torque in the program – 190 NM, we need to remove it and shift it to a larger number (it is better to trust a good specialist). Then the box will not fall into emergency mode.
