Ignitron ECU

Ignitron ECU is a plug and play standalone engine management system for the VW/AUDI/SEAT/SKODA 1.8 20V Turbo engines running BOSCH Motronic ME 7.5 ECU (also fits other platforms up to six cylinders, like VW/AUDI 2.5/2.7/2.8/3.2L after slight modification of the loom).

To whom do we recommend?

This is for the hardcore user, not for the faint-hearted! Ignitron ECU is recommended to be used on heavily modified engines with projected power levels well above or multiples of the original setup! The ECU lets you to run your engine based on true speed density method or with a mass airflow sensor if you like. It can be reconfigured within seconds (next to the track), logs selected variables into its own data logging memory and gives you flexibility which will never be available on a stock ECU.

Who should *NOT* buy Ignitron ECU?

If you got worried by a harmful fault code in your chipped vehicle previously, then this is definitely not for you! It may reveal additional problems with your engine (f.eg sensors on the way out, scratchy throttle pots, ...) which weren't obvious with the stock ECU. This is not the stock ECU, so do not expect your car to act and work just exactly like it! Setting up Ignitron ECU requires knowledge about engine management basics, so if you are not up for the task, consult with a professional tuner first! The usage of this ECU is solely your own risk! We do not take any responsibilities for any damage caused by/during using Ignitron ECU! Ignitron ECU may not be used on public roads in your country! For competition and motorsport use only! If you cannot accept these things, please DO NOT BUY Ignitron ECU!

Why Ignitron ECU then?

Ignitron ECU has been developed and tested on the later VW/AUDI/SEAT/SKODA 1.8 20V Turbo engines, focusing on all the distinctivenesses of these engines (natively supporting electronic throttle body, mass airflow sensor, MAP sensor in cooler piping, etc.). This is not an allround ECU with a PnP harness or adapter for the 1.8Ts, but a specialized engine management system for these cars: Ignitron ECU also communicates with the factory ABS/ESP module, instrument cluster (and haldex controller if exists) via CAN. If the stock engine arrangement (with a restrictive MAF sensor) does not suit your needs, this ECU lets you to run the engine on MAP sensor in the intake manifold (speed density) without the troublesome MAF sensor. Also you will be able to ditch all the unwanted solenoids, actuators, cans, bins, hair dryers and clean up your engine bay if you wish.

Troubleshooting with Ignitron ECU is easy as it can be, because you can log all sensors and variables simultaneously with the host software (this means several hundreds of variables at once) with sampling rate up to 33Hz. The ECU also has self learning capabilities: fuel injection adaptation to the lambda sensor readings or ignition adaptation according to previously recorded knocking. If something goes wrong, limp mode can be activated and the reason can be determined by the help of the fault code memory and/or the automatic data logger which can record 32 selectable variables into the ECU's own log memory up to several hours.

Since Ignitron ECU can be used up to six cylinders, it may be a good alternative for turbocharged VR6 24V engines (with a signle turbo), too.

Ignitron ECU comes with a host software running on the Windows platform. The ECU is connected to the PC/notebook or tablet via USB. Its user interface is simple, but effective. Do not expect any fancy eye catching graphics as in our understanding performance is more important than the looks! The host will run happily on a slow and old machine with Windows XP, even on the cheapest Windows tablet you can find (and can carry with yourself or permanently mount in your car)!

This application (which is of course a free download) can be used to set up the ECU and diagnose the engine. Loading a completely new settings file up into the ECU takes about 20 seconds, but if you change just a few parameters or maps, then the refresh takes a fraction of a second only. Hundreds of available variables and parameters can be recorded simultaneously during data logging. Forthcoming free ECU firmware upgrades are also vailable from within the host application.

Go to the downloads section to get the demo version.


The host software of Ignitron ECU requires a personal computer (notebook or tablet) with Windows XP or Windows 7 operating system. On XP it is happy with at least 512Mb memory and 1Ghz CPU, on Windows 7 (and above) it works best with at least 1Gb of memory and 2Ghz+ CPU. Windows 8.x and Windows 10 are also supported, though additional fine tuning is needed for these platforms (which is on progress), for the time being we recommend Windows 7. Minimum screen resolution is 1024x600 pixels.
