Just installed 450cc dsm injectors; now it craps out @ boost (te2)
i'm using the pgmfi boost rom; tuned with te2b9; it was working fine with my 240cc injectors + modified maps (rerichened up) and was running really rich under boost.
now i installed my 450cc dsm injectors; took the pgmfi1.0 rom; turned off launch control and now it craps out at boost (only running 4-5psi due to new head gasket + learning curve). It's like the boost cut feature kicks in but its suposedly not implimented yet... so wtf? Just for shits and giggles i threw in the ghetto dyne 450cc rom and it worked fine @ boost; just ran really lean everywhere else. So... why is it suddenly doing this? Also; i haven't tuned my fuel preasure; still waiting to get my fuel preasure gauge in, so i have no idea what its at; i knew that it was high for the stock 240cc injectors; but i dont know what preasure the dsm's like. |

The Dual Map ROM does this thing where is overly richens up the transistion from VAC to BOOST...try leaning out slightly one or two columns at a time starting with column 6 of the boost fuel map...and working you way to the right.
Do that and reburn and test...slight modifications unless you have a WB to test. |
