Hi mate, just got your txt. When using EDIS the trigger settings should be set to rising edge capture. This basically tells the ecu to RPM trigger on the rising edge of the CPS tooth, rather than the falling edge. This should in theory advance your timing slightly. Hence the need to check timing with a strobe, to make sure the advance the ecu see's is the same as the advance the engine see's (no offset).
Im not sure why it would cause a misfire, however looking at your datalogs the misfire you had was very slight, although it may have felt worse. There also wasn't a sync loss count that would be associated with a cps trigger fault.
There have also been very slight misfires caused by stupid things like cps wheel or cps mount jitter (you won't have this problem) but also by lumps of metallic shite stuck to the trigger wheel, however edis is normally very tolerant of thing like this.
Advancing or retarding the timing can have a significant effect of fueling (as you have found), sadly there is nothing for it but to re tune your VE table. On the rollers it isn't uncommon to re visit the VE table 2-3 times ie) after tuning the ignition table the VE table normally needs slight alteration....
You are probably idling like shite as AFR's are out, and timing is well out. Adjust the VE table for around 14.0 (to begin with), then adjust the timing around idle to see if advancing or retarding the timing helps.... this should give some indication as to your CPS trigger offset..... normal CVH's idle well at or around 12deg, if your using like 20deg in your table to get a good idle then something is wrong and your trigger offset.
Does any of that make sense lol? or am I rambling....
Rob,
