can you take a screen shot of your fuel tunning table and host it? if you have trouble hosting, you can email it to me,
[email protected]. Fuel injectors do not work off of voltage, they are a oscillating device (on/off). The ms open time represents the time "on" the fuel injector is during the stroke. This would let me know if you are maxing out your injectors, though, as with any maf interference device, you can only send the maximum value allowable at the end of the factory ecu's fuel table.
Yes, start pushing the af/r's down into the low 11's if possible, and get some kind of timing feedback at least (apexi multi checker... i think apex has another box out that will feedback timing), preferably something that can datalog the timing, though i cannot recall a box that will do this. Because the map-ecu is making changes to the maf signal, it is changing the timing when you change the "fuel/load" value.
