M7 Injector symbol

[CO_MapMaker]

Prettty sure I have a leaky injector on 05 M7, thought I got lucky with a complete throttle body, rail and injectors off Ebay for troubleshooting. I was thinking the injectors were color coded and the ones for sale were yellow like mine.

I guess I was wrong, I just recieved the package and it has a triangle on the injectors and I have a square on my ecu. I looked at my injectors and there is no symbol, but it may have worn off??

Please confirm I am hosed???

Sorry to say but you will either need to buy another set of injectors with the square symbol or fork out $1300.00 for a triangle ECU box. One will not with the other. There are (3) types of injectors and ECU's; square, triangle or circle.

Ya, The injectors you have will be square to match your square ecu. Just find another square set of injectors. The ecu and injectors must be matched..

Those injectors will work for trying. The injector symbol is the flow. the ecu is matched to the injector. Lets just say the circle flow the most, square in the middle, and triangle flow the least. If you use the triangle injector with a circle ecu you will be running leaner because the ecu is calibrated for the injector flowing more. How much more i don't know. Of course the easy answer is sell them and get some square ones, but if you have a fuel controller and temp gauges you should be able to make them work fine.

How did you determin they are leaking? I think mine are also.

I had one plug that would foul out every twenty miles and start running on one cylinder. The pto plug would be soaked and the other dry as a bone.

Took everything apart and checked the reeds to make sure they weren't chipped. I also cleaned every thing up, backed my oil pump off since it was way oil rich and added some injector cleaner. Rode the sled 50 miles Sunday and it ran strong all day.
