That does seem like a large difference. What would normally cause this?

Not sure. Maybe you should start a separate thread and ask some of the more knowledgeable members about the difference. Or ask Whipple?

What are your power enrich numbers. My initial fuel rail pressures were low and it was falling off about 5800. I fixed that and made another 40hp and my fuel rail pressure came back up to 2200 from about 1500.

I searched many articles, but not clear yet.

LTFT affects on WOT or not?
If it affects, where is it coming from? As I know, STFT is 0% on WOT , which means no learn for LTFT.

As I understand , the driver side is leaner than the passenger side.

at low : 1.22
at mid : 1.24
at high rev : 1.25

my stoich number is 14.68

and commanded AFR is 12:1 ~11.7 around

btw, recently I put AFR gauge on my car and it showed 10:1~10:8

Too rich than I expected, so I reduced the PE numbers to 1.22 on the all rev and it made 10.8~11.5 :1 on the actually AFR gauge.
Furthermore , my rail pressure was back to 13Mpa from 11Mpa range (from 1600 to 1900 PSI). It is not enough, but better than before,.

Not bad result. I believe that I made my injectors sprayed the way too much due to some mis-calibration like MAF and it triggered the lack of fuel.



Are there any other guys having Whipple and checked AFR with the stock flash?

My wide band is in the mail. I'll post up some numbers once I get it installed.

Hey shinysun,
I hope everything is looking better for you. If you don't mind could you tell me how you are data logging your ride? I'd like to do some logging on mine and just wanted to know what I need to do it? Just a heads up I have a MAC. You using a laptop/device/software?
Thanks

[laynlo15]

Those are good numbers on the power enrich. Basically right on point with mine.

Hey Joe, I'm a MAC guy too. These programs, logging/tuning are for Windows (at least the HPtuner I had) couldn't use it due to old unsuitable computer. SO, my tuner prints the number for me.

I do have access to other windows PC's but just not a laptop. So if I could log on a device uses a memory card I could then transfer that over to windows PC. ???

Hello,

I am using Surface 3 from Microsoft. It is quite nice for VCM program of hptuner.

Recently, Microsoft established Surface 5, so the price is relatively cheap.
Or, My recommendation is YOGA book with Window software. There are 2 types of YOGA book from Lenovo. Android and Window. Quite cheap, but powerful.

Thanks. I guess I'll have to get one from work to test it out.

I bought a tiny 2-in-1 windows PC from Walnart for $64 to use in the car. It runs HP Tuners great.
