The ORIGINAL VR4 Clone™ ECU!!!
I am proud to offer the VR4 Clone™ ECU!!!!
This was started way back in late 2009 when we first discovered that there are flashable ECUs out there.
With lots of work from the likes of Gatecrasher and Ceddy from the EVO community, the reverse engineering began. Since then I have been modifying and testing ECUs in the hopes to offer a SOLID VR4 Replacement ECU. And others such as Monochrome (aka Greg E) have taken up the task of completing a viable ROM to replace the stock ROM.
After a long time in testing to ensure that this is a 100% COMPLETE VR4 ECU, I am proud to offer the VR4 Clone™ ECU!
These are professionally remanufactured ECUs that have gone through an extensive process:
- First every incoming ECU is tested to ensure that it is working.
- Then the ECU has the conformal coating completely stripped with an approved conformal coating stripper, not brake cleaner, acetone, or alcohol.
The proper selection of a conformal coating stripper is CRITICAL to prevent damage to the printed wiring board substrates or other components.
- Then the ECU is examined under 10x power for surface contaminations, corrosion, and dendrites! Far too often on Mitsubishi ECUs, I have encountered extensive corrosion, dendrite growth & flux residues from flux that is not fully activated. Additionally, extensive flux residue can be found on almost ALL Mitsubishi ECUs. This can and will cause problems over time if not properly removed and reworked.
Here is an example of flux residue that has crept under the conformal coating and caused massive amounts of corrosion:
Here is a close up of corrosion on an injector driver final drive circuit. This is all sorts of bad!
And even more corrosion pictures:

Corrosion 03
Corrosion 05
Typically corrosion looks as if there is a discoloration in the conformal coating, sometimes white, sometimes rust colored. Additionally, the conformal coating can have particles trapped in it along with the flux residue. This is because of improper washing at the factory.
Dendrites are caused by the moisture trapped in the flux and wicking under the conformal coating. The moisture dissolves small particles of metal into a solution of metal ions which then are redistributed by electro migration in the presence of an electromagnetic field, i.e. electric current. After time, these small dendrites can and sometimes do turn into full blown corrosion.
For more information on dendrites and corrosion, you can check out the Foresite website.
- After the ECU is examined and any rework that is required is performed, the ECU is converted to the VR4 Specification. During this process, parts are removed and parts are inserted depending on the circuit.
Only BRAND NEW parts are used!
We do not use parts that are scrapped off of other ECUs for this process.
- The one and only capacitor, which is WAY beyond its design life of 2000 hours, is replaced BEFORE it can leak and damage the ECU. If you drove your car 1 hour a day, five days a week, 50 weeks a year (assuming you park it for vacation two weeks a year) your engine is running 250 hours a year. Considering that the 1999 is now 13 years old, thats 3250 hours! For most daily drivers, this is very underestimated!
Correction 05/25/2012
Mitsubishi used a Nichicon General Purpose 47 µF 50 V (180mA Ripple) Surface Mount Aluminum Electrolytic Capacitor. This part has a design life of 2000 hours continuous use at 105°C. This temperature can easily be obtained internally to the capacitor by a continuous ripple current greater than 180mA. This results in "soft doming" or "bulging" of the top of the capacitor which is an indicator of a pending failure. For more information on capacitor failures, you can check out the Consoles5 Wiki.
- Additionally, an additional capacitor is added to help protect against voltage and current ripple. This additional capacitor normally exists only on the DOHC SL ECU to help combat the extra current draw of the variable intake plenum actuators.
- The finished product goes through even more electrical testing and is certified to be a 100%VR4 ECU!
- Once final testing is done, the ECU is cleaned of all flux residues and re-conformal coated. The ECU is the re-packaged in an appropriate case and labeled with a part number and a warranty seal.
- Lastly the stock Mitsubishi ROM is flashed to the ECU before delivery.
All ECUs are covered by our extensive 1 yr Clone Warranty.
