multiple injector sizes
I am wondering if magesquirt can handle two different sized injectors on the same cylinder and if there is any support for it. I have spent hours poring over the manuals and have not found anything that suggests whether it can or can not do it. I am trying to find an EFI solution for a two cylinder engine with a very wide fuel demand and rpm range. Any suggestions will be appreciated.

Re: multiple injector sizes
Hi, Sean.
Staged injection - small injector for idle and cruise, sewer-pipe-sized injector for full throttle - is supported by the Extra code, but I don't believe the standard B&G firmware supports it.
Questions about the Extra firmware should be asked on the MSExtra forum; the firmwares and settings are different enough that asking questions on the wrong forum just gets people confused.

Re: multiple injector sizes
The B&G code could use dual table mode to give each injector set its own fuel table.

Re: multiple injector sizes
IN-teresting ... Tune the first table with lots of bottom end rows; last two rows dropping to ... 25%? The second table has the first row zero'd off, the second chiming in at whatever you want the secondary to start with e.g 5999 (0) 6000 (25%). Now THAT is a clever workaround!
