Hondata

this seems really weird your numbers are almost as high as bboy burst and he is running the ips k2 and you have stock cams making about the same power. not only that you guys are tuned by the same person on the same dyno seems kinda funny.

I was quite pleased. This shows that the combination of ...

Stock cams. No plans to change them at this point.

One more note: If I had it to do all over again, I'd buy whichever header I decided would work best for me and then build up a Vibrant HFC of corresponding diameter and a test pipe. Then I could run the HFC when I wanted to (most of the time) but still be able to switch over to no HFC for tuning and ...

do you have the vibrant header with the hfc? that's the one i'm talking about. my tuner said he felt that the design of the header, coupled with the hfc, is what held me back. i don't have any dyno runs, just my tunes.

dont u find 2900 far too low for vtec? i had mine at 3300 with another tune and ...

not sure if this is of any help. previously I had the vibrant header with HFC on my SI, and my tuner told me it was holding me back. doing a full tune, he found the lowest he could get my vtec engagement was 3900 before it lost power (a sign of how well or poor the motor breaths). I switched to the ...

Thanks. I will check on the part throttle/cruising AFR. Cams perform really well. I do have another problem though, not related to the cams or tune. I have a Vibrant RH w/hfc. The cat stank up the joint, so bad that the tuner had to run a tube outside the shop to remove the smell. Car smells really ...

Already done. I hadn't done it since I was tuned on the dyno last month. I'm seeing 1-2% at idle.

Thanks for clearing that up. Why does the idle need to be so high for the MAP calibrations? My '05 CR-V uses speed/density and idles at 650 RPM.

I believe the optimal idle speed for the K20 is 830 rpm or so.

Why would the Hondata AFM tunes and Honda's stock program be set to 750 then? I can ...

Thanks for clearing that up. Why does the idle need to be so high for the MAP calibrations? My '05 CR-V uses speed/density and idles at 650 RPM.

I tried lowering the idle speed to 750 RPM in the 149/176/194 cells and datalogged on the 5 mile drive home. The engine is still idling around 850 RPM. Any ideas why?

Alright, I datalogged a trip to and from starting with my tuned calibration (which has been running for about a week so idle is stable) and then reflashed with the 2007+ return to stock calibration. I came up with the following details with my tuned calibration on the left and the stock calibration ...

The ScanGuage uses air flow, with an assumed air fuel ratio.

That's kind of what I was guessing, especially after the load feature (LOD) dropped as a useful feature once I switched to a MAP tune. I now use the MAP reading in kPa to give me an idea how I'm loading the engine, especially since it ...

Do you know offhand what the ScanGauge is using to calculate fuel flow?

Anyway, as you mentioned, datalogging the two would be a surefire way to spot any differences. What calibration should I try using to closest resemble my Hondata Reflash state of tune?

While I can't verify whether the ...

Maybe you can give me some ideas as to why I'm burning more fuel at idle over stock.

Mods that didn't change and are:

AEM "V2" CAI
P2R Throttle Body Spacer
Intake Manifold Gasket
Vibrant Header w/HFC
Vibrant Street Power Exhaust (2.5")

Only thing that changed:

I went back to eliminating the ...
