Hello all. I have a couple questions about XDF's that i have. I use a 1227747 ecu and i burn my own chips. First, i want to know if the 7747 is $42. I have a couple of XDF's for the 7747 ECU and i have a $42 XDF file. The $42 file has BLM cell boundaries and the 7747 file doesnt. They all seem to work ok. Second, i like the 7747 XDF file i use but i want to have the BLM cell boundaries from the $42 XDF. i have tried manually putting it in (insert new XDF item) but it screws up the rest of bin. I use TunerPro. Could someone shed some light on this?

 

ok, i have sucessfully added BLM cell boundaries items in my 7747 XDF file. thanks. There still is that unanswered question about spark latency. I do believe that this delays the spark. Any one messing with the 7747 ecu on their TBI car like me? I've been messing with injector bias settings trying to get stock open loop settings close to running with my setup.

 

The 42.xdf file is offset on the fuel map.

 

OK, its just with $42 XDF the rows and columns are switched
