The kit for the 2009+ CTSV is exclusive to us (kdinnovations). All components other than the blower and manifold are ours.

Your image is MAF vs WB Error but your STFT are on? Run it in open loop if your going to use MAF vs WB Error.

You changed you shift MPH but not your Lock up speed.

In some places your commanding lockup before its even in the respective gear at a given throttle position.

Also, if you don't have a cam is there a reason your spinning the thing to 6600rpm ? The stock cam with your boost level stops building power at right about 6000rpm which if you look at you IJDC at...

You are past the power level for the injectors. I have been there. Currently running ID850's and north of 650rwhp and all is well. 57% on meth 71% off meth

550rwhp @ 11.6:1 AFR you need to think...

Had the deka's idled like crap in the heat, had drilled POS fueled like crap across the board.

Bought ID850's from DSteck and never looked back, I will never use another injector and never worry...

Did you disable DFCO?

Got my ID850's in...

What a dream to work with:

Idle quality A+
Lower STFT swings A+
Steady state fueling A+
PE AFR stability A+

Thanks Dsteck and Paul...

Thanks to DSteck my ID850's will be heading to their new home soon in my 2009 CTS-V

Stock injectors posed the same issues after looking at my tune when they were in. I have logged delta pressures RPM VS ECT (attached image).How do I test for EVAP Purge. The ID850's you spoke of, do...

I found something crazy today.

I pasted all of my MAF data in a spreadsheet from current vs stock, then my current vs another CTS_V with the same mods and my lbs/hr are 50% higher than both with...

Injector data was scaled based on 80.14lbs/hr@58psi which is what the company that did the injectors said the flowed.

Stock ones should be the same as the ls9. On the CTS-V's we are maxing them out at close to 600RWHP I was at 110% IDC @ 6200rpm and 11.6 AFR before punching them. Wacky thing is the 80"s show 75% at...

I have read Google's posts.

I find my eyes wondering left when reading... Then right a bit, then left again.

After hours of logs and adjustments, with my limited knowledge I believe I have bad...

No doubt.

Car ran better in forced open loop.

Loaded stock tune and starting from scratch.

Why can't there be an "easy" button :banghead:

Thank you

Geez, I never realized how raped the stock PE table was. It commands 11.02AFR up top though

Here is my tune. I am running MAF only right now to keep anything from skewing my trims

Only under heavy load, like pulling a grade while on it for a few minutes. Not too horrible

Running 11.6 AFR in PE on my NGK

No DTC's... But it seems resonable. Did you pick up any power?

Yes I do. Kooks

Whats up?

Smooth as silk on the MAF and was replaced with a dealer MAF. Checked for leaks, none. Also new coils, wires and TR6's

Yup, checked for leaks as well

2009 CTS-V, Kooks LTH, CAI

I am experiencing swinging fuel trims at idle and part throttle under load. STFT bounce around a bit and LTFT swing from -15/+25 on the same log and constant ECT 187deg....

The last part of the formula is wrong:

Take (14.628*.48) first
14.628*.48=7.02144

Now take 5/7.02144=.71210

v
______ + 9.0693
.71210

Post #8 explains it better than I can
