Can a few of you veterans out there please offer feedback regarding this dynograph?
This is new to me, but I am skeptical here. (IMG:style_emoticons/default/confused24.gif) Thanks! Mike in Munich Attached thumbnail(s) ![]() |

Are the injectors firing sequential or batch? If sequential I'm thinking 2 might be called out in the wrong order? With the sudden drop in power and still running rich could the engine be sucking puddled fuel? I helped a guy tune the maga squirt on a subaru that dropped power right at 5k , but the a/f was 16.5.

Are the injectors firing sequential or batch? D-jet fires the injectors in pairs, diagonally across the engine. One cylinder gets its fuel pretty much as the valve is opening, while the other gets sprayed against the back of the intake valve. L-jet is batch-fire, with all four injectors being triggered twice per cycle (with half the required fuel quantity being injected each time). I believe that means that every cylinder gets fuel against the back of the closed intake valve, and also gets fuel when the intake valve is open, but I could be wrong on that. --DD |
