totally agree about forking the coin for a MRT job... (to me its a work truck and a LOT of fun / distraction on this forum discussing)
MRT earn the coin is my observation only. (for the obvious data acquiring, analysis hours, testing, risk etc)
The lameness of where it cuts in and causes the problem makes it sound like a simple fuel supply issue to me! but WTF causes it is another matter... whether its electrical/voltage OR just plain simple bad programming?
i think the NOVICE (like US and ME!) should be VERY careful with ECU software.. Its a license to kill... (kill the engine forever that is) and i like my 10year 160,000Km drive train warrantee!! (it was a major selling point for me!)
My father is into this stuff (developing the radio modems that beam back car ECU and sensor info to the pits as seen in byond2000 in the early 90's and on bathurst... now used by all form of motorsport worldwide) and he telling me to be damn carefull! They blow lots of engines but could afford it.......
food for thought!
PS> have PI system (8 channel data acquisition) stuff for this kind of testing but DEF dont have the time to get invoilved at this point in my life... PM me if u wanna use it! Was originally used for karting and has all those sensors and dash for that pursuit, so will have to spend some $$ to make it useful for this app. Motek etc have become popular copies of this system and PI are the kings.. ie. F1 staple... flame me down baby! hahahha)
