How do my injector balance rates look?

[cstephens93]

I just flashed in some DSP5 tunes on Friday from ATP trucks and am wondering if my balance rates were fine or not.

According to my Edge Insight at operating temp, they read as following.

Injector 1 -0.4
Injector 2 0.7
Injector 3 -0.2
Injector 4 -1.4
Injector 5 1.5
Injector 6 -0.4
Injector 7 2.5
Injector 8 -2.5

Are these fine?

All good. Did you have it in gear?

 

[cstephens93]

Nope I just pulled into the grocery store parking lot and had it in park.

Should I take a look at them in gear as well?

That's the best way, at op temp & in gear.

Okay I'll check back and see what they look like

I know you're doing this for giggles but in case you ever need it;

Yeah i actually read that post earlier on another forum. But I had trouble sorting through what to look for with just an Edge Insight CTS

Are you in the DSP1 default stock tune position?

I was on the 3rd position which is my DD/Econ tune.

My positions are

Heavy Tow 30hp
Light Tow 60hp
DD/Econ 120hp
Street 175hp
Race 230hp

Yeah you either need to be in a stock tune or recalculate for additional fueling.

Yeah I was wondering about that. I spoke with someone at ATP and he said my injector rates shouldnt change because Rob rarely makes any changes to the tunes at idle

Ferman tuned my truck and he said he leaves the stock tune in the DSP1 default position minus the few emissions deletes for my truck alone for diagnostic purposes and in case something malfunctions in the wiring I will have my stock tune to safely drive as necessary in case I'm towing...

Yeah I can definitely flash the stock tune back in no big deal. Aside from that, I was just wondering if these rates looked "safe" in general


In that thread "VVT trucks(LLY+) with the turbo closed at idle like in stock tuning will be closer to 9-almost 10MM3 of fuel at idle due to the extra engine load to spin up the turbo at an idle with the veins closed. And your in gear under these conditions should be roughly 10-13MM3 of fuel. Here is where knowing the fuel rate is so important and why it MUST be figured in."

LLYs are VGTs right? Or is VGT synonymous with VVT?
