Whats up Honda-tech. Cutting right to the chase my friend bought a k20a2 with Rcrew stage 2 cams Big tube swap header with 3in collector and custom 3in exhaust and RBC. The problem is it came with injectors and they didnt tell us what kind they are. we are under the impression that they were precision 510cc high impedance injectors. We have no verification and all we have is serial number on the injectors and we are looking for a little help on what kind they actually are. The serial/part # is RD17 and under that says AAST. Another descriptive characteristic they have a pink dot on them at top right near fuel railif ur looking at them installed and they are jet black. Listen guys, any help would be greatly appreciated we have a tune coming up next thursday and were trying to get that basemap going. were also running hybrid harness and were not getting a reading to the oem a/f meter and its brand new denso. any ideas help thanks Honda heads
