Are the cylinder #s by the firing order or the actual cyl as labeled? Such as is BALRCYL2mm3 actually #5 inj?

They are listed in numerical order from front of motor to the firewall.

That was my thinking also until this morning. I had a truck come in that logged #2 injector at +4.0 and would never change. I pulled #2 cyl injector and replaced, logged and no different still +4.0 with no fluctuation. So I recall on the modis or mentor that it list the injectors in order from firewall but also in parenthesis has them listed in firing order which would put #5 cyl as Balrcyl2mm3 . I pulled cyl #5 inj and replaced it leaving #2 new alone for the time and logged it. Problem solved.
Hope I explained it well enough to understand.
Interesting...

there is no good scanner to do this at the shop i use to work at we use to pull the injector wires to find out what injector it is
#2 and #5 are running mates in the firing order
97 2500 ecsb 5.7l/4l80e/4x4 411 pcm /thorley tri-y's/dual super 40's with x (catless)/aem cai/msd 6a and coil/zz4 cam/beehive spring/lm-1
stock sucks
Ok, I want to hit on this some more...
Im having an injector issue and just out of curiosity I would like to see if I can nail down which injector is causing the problem. Im getting ready to buy 6 new 120's and I just figured I would try and do a little investigating before I pull them and send them to the injection shop for testing. So I set up my dash page with the injector balance rates and Im wondering why I have cylinder balance rates for 1-5 but no 6?
What would be considered normal for the balance rates? I have one injector that is showing 4.0 at idle and the rest are fairly close to each other but Im also not showing #6.
Here are the rates that Im showing at idle:
cyl 1.... -1.1
cyl 2... -2.6
cyl 3... 4.0
cyl 4... .03
cyl 5... -3.9
If I can figure out how to post my log file I will or maybe someone can show me how to do it I would be appreciative.
The closer to 0.0 the better. A +4.0 is telling you that the ecm its really working that injector to try to get it to balance out the engine. On the other hand a -4.0 would mean the ecm is trying to cut that injector to balance out the engine.

Your +4.0 hole is the dead injector...the ECM is calling on the others to help balance idle quality.

Thanks guys. I kinda figured as much but its nice to get some knowledge from the experts.
But why is there no #6?
On a side note, I just dynoed the truck and I've been loosing hp gradually and that was my first suspicion something was going on. Here in the last week or so its been fairly warm here and I'm geting some white/blue smoke at startup with about 5 seconds worth of rough idle. So I know whats gotta happen next.
But it did put down almost 550hp and 1066 like this.
So at about + and - 4.0 means the injector is starting to go out? Is this at idle or what type of driving? I think mine might be starting to go, but of course still hoping not... Don't mean to derail this thread, but I've been looking for this info.
