ECU Upgrade

[nj1sh]

Anything good for 4th gens out there? I heard about this chip called d-boost or dyno-boost not the one on ebay that costs $39.95 the one that costs around 300$. it claims the following:

# Improves engine output by up to 15 %.# Enhances Nm, throttle response, acceleration and torque in the full RPM range.# Performance level setting from 0 - 100 %.# You can set the preferred higher air/fuel ratio than the stoichiometric fuel mix.# Unit is not a simple resistor.# INTEGRATED O2 - OXYGEN SENSOR SIGNAL CONTROL to avoid undesired restriction of ECU# Peak up acceleration and dynamism by up to 30 %.# Results higher top end speed.# Long duration - 10 years warranty.# Easy universal 20 minutes installation.# Immediate effect even during driving, no ECU learning period.# Reduces flat spots or delay time when you mash down the throttle.# It does not affect engine endurance.# Bright red light design.

Sounds like BS to me. There are JWT, technosquare, as well as a limited number of others (I believe) that make ECU upgrades for our cars.

I know about the JWT but it seems too expensive. This chip seems to be popular they even made a fake bs one that sells on ebay.

This is exactly the same cheap chip that plenty of eBay scammers carry, with the exception that it has a wire that goes to the front O2 sensor. All it does is trick the Intake Air Temperature sensor into thinking that the outside air is colder than it really is. The wire to the O2 sensor puts it offline -- as would be the case when the engine is cold.

It is crap. Do not buy it.
