Isn't that interesting!
I'm a bit of a questioner when it comes to things like this. I'm good at asking 'why?'.
'No dakta you cannot cook toast with your ecu!'
'It has high power switching circuits, with mapping for temperature response. SO WHY NOT!?'
Get an ecu, set all the maps to zero. There's your canvas picasso now paint. There's absolutely no reason I suppose for doing this, but if there's something you want to control and the immo can be removed, as can pesky fault codes, then why not? who wants to sit up all night soldering pic processors to control something an ecu can do off the shelf?
Another tuning question I always wanted to ask, but never dared....apparently the 8051 processor used in the msa11 series of ecu's can have it's code on external memory. (no **** sherlock I hear you say). Now here's the real 'out of the box' thinking...doesn't that mean if you found out what output went to the engine management light, you could....program your own engine lightswitch rave?
I know this all sounds silly...I'm a very curios man!
