2010 Camaro Injector Question

[30thta436]

I am wanting to upgrade the injectors in a 2010 Camaro. I have a few Questions.
1: What are the stock injectors rated (flow rate at what PSI)?
2: Is the injector flow rate vs. pressure the only table I need to change?

I am putting in injectors that flow 52lbs/hr at 58psi......Does anyone have an injector table for this?

Why are you going bigger? The stock injectors are 39 @ 58.

If you are going to do this, get injectors that come with the correct data or you will be fighting is forever.

Answer

2. No there are several others (Greg Banish DVD has all the data you seek though). You can literally copy paste the data you need. Summit.com Search Tuning DVD.

What injectors did you purchase by the way, Manufacturer/Part Number?

You also need to inform us of why you're upgrading the injectors? Unless you are running more than say 550 to 600 rwhp N/A, there's no sense in changing out the factory injectors. You must be going to forced induction?

As for what size your injectors are, if you go by GM's factory 2010 Camaro and 2009 Corvette LS3 data, they are 45.14 at 58 psi. If you go by the factory G8 GXP data, they are 46.06 at 58 psi. If you go by the factory '08 C6 data, they are 41.74 at 58 psi.

Just for my info. Can't the injector sizing be obtained through reading the tune? Just curious in case I ever came across a car with unknown values off hand.

Mine are 41.6, assuming I'm not totally reading the data wrong.

Mine are 41.6, assuming I'm not totally reading the data wrong.

It's possible the beta I'm using is showing the wrong data. See here for an example of an older beta versus the newest one on a G8 GXP file:

	18.6	20.9	23.2	25.5	27.8	30.2	32.5	34.8	37.1	39.5	41.8	44.1	46.4	48.7	51.1	53.4	55.7	58.0	60.3	62.7	65.0	67.3	69.6	71.9	74.3	76.6	78.9	81.2	83.5	85.9	88.2	90.5	92.8
	41.59	41.59	41.59	41.59	41.59	41.59	41.59	41.59	41.59	41.59	41.59	41.59	41.59	41.59	42.14	43.49	44.80	46.06	46.81	46.81	46.81	46.81	46.81	46.81	46.81	46.81	46.81	46.81	46.81	46.81	46.81	46.81	46.81

Newest beta below (now the values are completely different for the axis label):

	18.6	21.5	24.4	27.3	30.2	33.1	36.0	38.9	41.8	44.7	47.6	50.5	53.4	56.3	59.2	62.1	65.0	67.9	70.8	73.7	76.6	79.5	82.4	85.3	88.2	91.1	94.0	96.9	99.8	102.7	105.6	108.5	111.4
	41.59	41.59	41.59	41.59	41.59	41.59	41.59	41.59	41.59	41.59	41.59	41.59	41.59	41.59	42.14	43.49	44.80	46.06	46.81	46.81	46.81	46.81	46.81	46.81	46.81	46.81	46.81	46.81	46.81	46.81	46.81	46.81	46.81

I'll report it to support and ask them if it's a bug.

Okay, the newest beta is correct. Here's the answer from Mr. Bill (thanx!!!):

GM has changed the axis to 128-768 in steps of 20kpa.

It affects some E38 & E67 operating systems from what we can tell. I know we did the Camaro def & we're working on the others (not sure if they were all done or not, I'd need to check our engineering tracking log).
