Cheers Muz,
Roger, MS2 can run full sequential fuel and spark with the new code but you need a cam shaft position sensor too. I will be trying semi sequential as soon as my maps a little better.
Main advantages are (apparently!) better fuel consumption, better emissions and a better idle (its especially good at lower rpm's) with larger injectors.
BUT
Im doing because you can alter the injection time (when you inject fuel in the combustion cycle) and because you can set individual cylinder trim values. This means if one cylinder is slightly lean but the others are slightly rich (giving an average AFR from your single lambda) you can tune it out. Im going to do this with 4 EGT probes and a datalogger.
But generally batch injection is just fine.
Rob,
