It's actually quite hard to corrupt the firmware in a microprocessor, you
have to do a certain sequence of instructions to even get to the stage where
you can write to the EEPROM in that that contains the firmware.
It's more likely to be an obscure bug in the megasquirt code than an actual
hardware problem.
I think i'm getting old as the 320bhp in your daily driver certainly felt
fast enough to me when i was in it recently !!

Yay! At least it's had less firmware updates than replacement engines..
However the majority of those just weren't powerful enough rather than
breaking them. ;-) Keep the laptop in the car on the longer runs just in
case. It may be worth popping the case on the ECU and seeing if there is
anything loose.
Now the big question - do I start modifying my daily driver? 320 BHP is
starting to be "not enough" ;-) ( I do have nearly twice the weight of the
quantum, so I'm not quite as fast as F619 ...
Good result,
M

A massive thanks to Jim and Matthew for their assistance with this problem.
Had to run a 15 metre network cable to the garage to allow Jim to log in and
carry out a firmware update on the megasquirt ECU which looks to have sorted
the misfire. All functions on Megatune are now working. Isn't technology
great sometimes.
Need to do a road test to try it out but heavy rain and flooding don't
really mix with a turbocharged open top car, so the road test will have to
wait for now.
