Thats the one I have for my Cosworth V6. What exactly do you mean by "self mapping" though?

Was sifting through the ecu possibilities when i stumbled across this article.

I have had two of the emerald ecu systems but did not realise they had come so far in recent years. The last one I had was torture and i ended up at emeralds to get dave walker to map it. . This new k3 with the adaptive learning has to be a godsend. It appears to be totally home user friendly, or is it cxxp?

It is adaptive to AFR as long as a wide band lambda sensor is used but that hardly makes it self mapping in my view. I still believe it is a cracking ECU and I fully intend to take mine to Dave Walker's place in Norfolk for a proper rolling road setup once completed, god only knows when that wil be though:o .

a megasquirt wired up to a laptop and megatunerstudio ms can ajust a map as you drive
seems pritty handy if your setting up your own

It will adjust your fuelling with a wideband Lambda - but you will need to have a target AFR table set first.

ms can do it with tuner studio you give it an afr target at a particular rpm/boost setting it will try to hit it. it still doesn't replace mapping properly on a rr and doesnt work too well if the base map is really poor but should stop you having any accidents with fuelling and get the car running pretty reasonable.

yep ash is right. as for all of the ecu's it requires you have all the ign timmings set right in the first place
where a rolling road is handy but its good to have for iva and getting the car driveable and running ok also save a few quid when it comes to dyno time
