Be driven with Superchips Limited, established 1977

Superchips optimizes the performance of your car, helping to maximize your driving pleasure. You may not know this, but your car comes with artificially imposed limitations on its performance. Manufacturer deliberately restrict the performance of your engines in the name of reliability, to allow the engine to have a long service life even in the face of negligent owners and sub-standard fuels. Superchips promises a solution that frees your engine from those restrictive limits and rewards you with a more exciting drive.

Lower fuel consumption and better performance

In today’s market with soaring fuel prices, a Superchips remap means IMPROVED FUEL ECONOMY as well as improved performance – saving you money on the long run. You don’t put limits on your life, so why put limits on your car?

Every Superchips optimisation delivers:
- an engine that responds more eagerly to your right foot
- smoother power delivery making town driving much easier with fewer gear changes
- improved acceleration for safer overtaking

For non-turbo petrol cars:
- up to 10% more power
- enhanced throttle response

For turbocharged petrol cars:
- up to 20% more power
- up to 25% more midrange torque

Superchips, backed by over thirty years of experience in enhancing the performance of turbocharged engines, carefully matches increases in turbo boost pressure with the remapped ignition timing and fuelling. It doesn’t affect reliability or the life of the engine.

For turbo-diesel cars
- up to 30% more torque and more power – fuel economy improvements
Here too, the promise is on an enhanced drive by ensuring the remap matches fueling to increases in boost pressure.

How does Superchips ECU remap software work?
Since the early 1990s, most engines have been controlled by an on-board computer, the engine control unit (ECU), which amongst other functions, defines the ignition timing, fuelling and boost pressure for all given engine speeds and loads.

After extensive development and testing, Superchips arrives at the optimised settings for your make and model of vehicle, ensuring that each remap is as individual as the software inside your ECU, safely eliminating those ‘performance compromises’.

In most cases this remapped program is installed electronically and remotely through the car’s diagnostic port; there’s no replacement chip, and the ECU itself is not touched

Each vehicle is always tested by Superchips personnel before being handed back for its owner to enjoy, to ensure that everything operates as it should be.

Find a Superchips remap for your car
The simple search mechanism on the Superchips official website enables you, within seconds, to find out if a Superchips remap is available for your car.

Simply choose the appropriate make (e.g. Audi) and then choose the appropriate engine type (e.g. petrol).

If a Superchips remap exists for your car you will be informed of the power gain expected (with power curves, where available) and the price.

ECU pin-out Assignment

Monday, April 14th, 2008

Well, as a kick start, I have decided to post something I did back in 2006. Some might find this hard to digest, many will find it useful I hope.

For those who are driving a Satria/Wira/Arena 1.3/1.5/1.8, manufactured from late 2001, to date, your engine (4G13/4G15/4G93) is managed by a new ECU made by Siemens-VDO called EMS 400.

This ECU has two sectors called ECU1 and ECU2, with 120 pin terminals in total. Only 45 are used for the 4G13/15.

Here’s the pin-out I managed to assign

 ::ECU terminal number (Wire color code) Assignment::ECU 1 (black connector)
2 (B-Y) ignition switch-ST (M/T)
3 (G-Y) A/C compressor relay
5 (Bk) ground
7 (unknown*) post-cat O2 sensor heater power
9 (Bk) pre-cat O2 sensor heater power
10 (Bk) ground
11 (R ) power supply
12 (R ) backup power supply
16 (B-Y) pre-cat O2 sensor ground
17 (W) pre-cat O2 sensor signal output
18 (B-Y) ignition switch-ST & inhibitor switch A/T
19 (unknown*) post-cat O2 sensor ground
20 (unknown*) post-cat O2 sensor signal output
27 (B-W) dual-switch for condenser fan relay
29 (L-Bk) ignition switch-IG
33 (W-R) power supply and fuel pump control relays
34 (Br-Y) purge control solenoid valve
35 (G-Bk) engine fan relay
37 (Y) unidentified
38 (G) unidentified
44 (G) A/C switch signal to A/C control unit
58 (Bl) unidentified
59 (Y-W) vehicle speed sensor
60 (W) unidentified

ECU 2 (gray connector)
63 (Y-Bl) injector #1
64 (Y-Bk) injector #2
65 (B-G) injector #3
66 (L-W) injector #4
67 (R-L) ISC servo motor power (+5V)
68 (Bk) ISC servo motor ground
69 (Bk) ground
71 (B-Y) ignition coil power transistor control
72 (B-R) ignition coil power transistor ground
78 (Y-G) coolant sensor power (+5V)
79 (Bk) IAT sensor and coolant temp. sensor ground
80 (Y) IAT sensor power (+5V)
81 (G) MAP sensor power (+5V)
84 (G) TPS ground
85 (W) TPS
87 (L) TPS
89 (G-R) TPS
99 (Bk) crankshaft sensor ground
100 (W) crankshaft sensor power (+5V)
104 (Bk) cam angle sensor ground
105 (Bk) MAP sensor ground
106 (W) cam angle sensor signal
108 (G-R) MAP sensor signal
112 (R ) cam angle sensor & TPS power
117 (unknown**) knock sensor
118 (unknown**) knock sensor

* Step III engines only
** 4G9 only
unidentified pin out – presumably to dash dials and indicators

Wire Color Code:
Bk = black
G = green
Y = yellow
R = red
W = white
L = light blue
Bl = blue

Disclaimer: information provided might not be 100% accurate. However, I spent 3 hours taking the ECU out for the Wire Color Code, and putting it back. Terminal Assignment is based on the official information gathered via undisclosable sources. Use this information at your own risk.
