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!

 

You might want to post this in the K series section.

 

very well...

 

but still no one knows what injectors these are?

 

Just in case this helps we figured out the o2 problem thanks to the guys at hybrid racing. very good people. the wiring on the o2 or harness was mixed up some how so if any one else is having an issue i have the correct pinouts here if u need them. Goes as follows, The correct sensor should have a WHITE/BLUE/BLACK/BLACK. Take them all out of connector and put as follows. (This is for a k20a2 in 2001 Integra Gsr with hybrid harness btw) The white wire on the o2 goes to-solid green on harness. The o2 blue wire goes to yellow/green on harness. Blacks on o2 goes to either of the red or white on harness.Hope it helps someone else too
