KMS Management ECU MP25

After 20+ years of successful sales KMS made the difficult decision to discontinue the MP25 from 2025 onwards.
We are aware that many of our customers are still driving a MP25, this has been our best selling product for many year.

Of course, we will continue to support customers and dealers who have purchased this product for 2 years after the date of purchase, free of charge, within the warranty. We expect to be able to carry out repairs for a number of years longer, provided that the components remain available.

If you drive an MP25 and would like an extra ECU, do not wait too long because stock is limited!
If you are considering buying a KMS ECU, we recommend that you go for the improved version, our MA-5.
We now offer this together with a Lambda controller set for €875 excluding VAT.
If you have any questions, please call or email us!

The KMS MP25 ECU is an efficient, enthusiast-level engine management system designed to get the most out of your vehicle. By using the minimum of sensors, three auxiliary outputs, one auxiliary input and a wide range of functions, the KMS MP25 ECU can cope with 90% of all types of Otto engines.

These basic functions make the MP25 a simple, reliable and effective engine management system at a very competitive price.
