Full details
Description
The ME221 Wire-In ECU is a feature rich and future proof four cylinder injection engine management system. Built from the ground up using the latest control strategies means a modern, powerful, VE based ECU, with enhanced feature set including closed loop boost, in-built Wideband Lambda Control, DSP Knock Control, on-board data Logging and VVT control – all in a compact form factor. Massive IO means the M221 can handle anything thrown at it, and custom tables means any specific algorithms required can be easily derived.
The ECU comes complete with a fully terminated Vauxhall C20XE/LET loom to get you up and running in no time. It is suitable for either the stock inlet, turbo, or throttle bodies. Note you must use the later VR type crank & cam sensors and 4 pin Vauxhall Coil Pack with this setup.

Who you are buying from
You are buying from a drift team, not a warehouse.
Our founder competes himself in his own drift E46. Our team build and race the same platforms you drive and work on, and our sponsored drivers chase championships on the same parts we sell worldwide.
01
We have already broken it for you.
Our founder, a full team of sponsored drivers, and hundreds of other drivers worldwide are out competing on this stuff in drift and rally. When we tell you a part is good, the part is good. It has already been put to the test.

“After trying a few better known brands such as Tilton and Extreme, and never being super happy... Conor was able to recommend me the perfect clutch for my application... I havn't broken any drivetrain parts since I installed it.”
Connell O'Kane, 2JZ drift car, 27 Jul 2024

Tell us the car. We will spec it.
Chassis codes, spring rates, angle kit clearances, clutch ratings. Send us the car and what you want it to do. The answer comes from someone who has run that setup, not someone reading a product sheet.

“Conor is a top man very helpful and always replies to any questions you have about his products.”

Ordered before 1pm, fitted this weekend.
In-stock parts ordered before 1pm are dispatched the same day. UK and Ireland typically arrive next morning, worldwide as quick as three days. Times do vary, but that can mean the part is on the car within a few days and she is back out blasting the roads by the weekend.

The price you see is the price you pay.
Duty and taxes are pre-paid, so there is no customs bill waiting at your door. What the checkout says is what it costs, wherever you are.

Straight answers
The questions you were about to open a chat about.
How do I know it will fit my car?
Send us your chassis code or your reg in the chat and we will confirm before you spend anything. If you order and it turns out to be the wrong part, we swap it.
“Had a mix up with the item description (order wrong part) they was quick to email me and see what part I was meant to order and substituted it for no extra cost!”
Bradley Page, verified customer, 31 Jan 2025
When will it actually arrive?
In stock and ordered before 1pm, it leaves the same day. UK and Ireland is usually next day, occasionally 1 to 3 days. Europe 1 to 5 days, rest of world 3 to 5 days on express.
If something is not in stock, we will email you right away with an ETA and any available substitutes. On the rare occasion it does not work out, we will happily refund your order.
Will I get stung for customs or import VAT?
No. The price you pay on our website is what it will cost to be delivered to your door. You will not receive any surprise surcharges after ordering.
What if I change my mind?
30 days on all stock items, full refund on the parts. If you ordered the wrong thing we will help you get to the right one for as little money as possible. We have been there.
What warranty do I get?
Everything on our website is covered by the standard manufacturer's warranty.
If you ever need to claim, we fight your corner. We will do everything in our power to make sure you are looked after, rather than leaving you to argue with a manufacturer on your own.
Can I pay it off over a few months?
Yes. Klarna and Shop Pay Finance are both at checkout, so you can spread it without putting the build on hold.
Can I just ask someone what to buy?
That is the bit we are actually good at. We run our own race team and workshop, so you are talking to someone who has fitted it, broken it, and fitted it again. Hit the chat and tell us what the car is doing and what you want it to do.
