Power Gains on your website

Access

1. Have an ECU-LAB account with an active plan.
2. In your account → API keys, create a key and list the websites where it may run.
3. Paste the code on your website (or install the WordPress plugin) and choose your colours.

1 · Widget (JavaScript)

Two lines in your page. The widget builds the selector, draws the chart and the table, and adapts to the width of the page.

<div class="ecu-lab-gains" data-key="pk_…" data-lang="en"></div>
<script src="https://ecu-lab.online/assets/widget/gains.js" async></script>

Optional attributes:

data-key	your public key (pk_…) — required
data-lang	language: en, de, fr, it, es, pt, nl, pl, cs, sk, hu, no, ro, el, tr, sr, bg, uk, ru, zh, ja
data-category	cars · trucks · agro · moto · boats · machinery — show a single category (without it, the visitor chooses)
data-unit	hp · kw
data-colors	JSON with the colours (names in the table below)
data-color-hp-tuned …	a single colour, e.g. data-color-hp-tuned="#ff6a00"
data-disclaimer	your own note under the chart (a note is always shown)

2 · Iframe

For page builders that do not accept scripts. No border, transparent background; with the script on the page, the height adjusts to the content.

<iframe class="ecu-lab-gains-frame" src="https://ecu-lab.online/embed/gains?key=pk_…&lang=en&c_hp_tuned=ff6a00"
        style="border:0;width:100%;height:640px" loading="lazy" title="Power Gains"></iframe>
<script src="https://ecu-lab.online/assets/widget/gains.js" async></script>

Colours go in the address as c_<name>=rrggbb (without #). The iframe only opens on the websites listed on the key.

3 · WordPress plugin

Install the plugin, enter your secret key once in Settings → ECU-LAB Power Gains, then place the shortcode or the “ECU-LAB Power Gains” block wherever you want. The key stays on your server.

[ecu_lab_gains lang="en" category="cars" hp_tuned="#ff6a00" nm_tuned="#0e2342"]

4 · From your server (REST)

For your own integration: JSON responses, authenticated with the secret key. Never put the secret key in a web page.

curl -H "Authorization: Bearer sk_…" \
     "https://ecu-lab.online/api/v1/gains/vehicle/12345?lang=en"

GET
/api/v1/gains/config	colours, categories and texts in the requested language
/api/v1/gains/categories	categories with the number of vehicles
/api/v1/gains/brands?category=cars	makes in a category
/api/v1/gains/models?category=cars&brand=…	models of a make
/api/v1/gains/years?category=cars&brand=…&model=…	years / generations of a model
/api/v1/gains/engines?category=cars&brand=…&model=…&year=…	engines (id, name, fuel)
/api/v1/gains/vehicle/{id}	power, torque, Stage 2 where available, chart points and axes

Common parameters: lang (language of the texts), unit=kw (power in kW instead of hp).

Chart colours

hp_tuned	Power — tuned	#1f74e0
hp_stock	Power — stock	#8fa3b6
nm_tuned	Torque — tuned	#e8a33b
nm_stock	Torque — stock	#b39b70
stage2	Stage 2	#7357d6
grid	Grid and lines	#e2e9f1
text	Text	#4a5d75
accent	Accent (selected fields)	#1f74e0
bg	Background (or “transparent”)	transparent

Any colour you leave out keeps the value saved on your key, then the default.

Rules

• The public key only works on the websites listed on it; the secret key only from a server.
• Limits per account: 120 requests per minute, 20.000 per day.
• The figures are estimates and the note under the chart is always shown.
• Keys work while the account has an active plan; they stop when it expires and start again on renewal.
