Just got off the phone with Doug from Hondata...

[silverspoon1996]

I own a K24 and Brian Crower stage 2 cams. He said because our cars have a MAF sensor... it accepts changes in air flow well.. it will run correct Air fuel ratios ONLY IF YOU USE THE ORIGINAL INTAKE PIPING. He also said Hondata has tested with the TSX cams in our cars, and the 06+ TSX camshafts are a Type R high cam on the intake with the 04 tsx small lobe on the intake.. and the Exhaust has been unchange.. they are LARGER then any other Type-R cam.. Most of us know this..

He hasnt tested any other aftermarket camshafts but said they POSSIBLY could work as long as there is no valve/piston Valve/Valve clearence problems.

also.. our cars with a reflash.. can run a K24 engine with good air fuels.. People say they lean out uptop... but he assured me the Air fuel because we have a MAF isnt the problem.. its the fact that the K24 is not mechanically designed to spin to 8,000+ that it will blow up.. ITS NOT HOW... its WHEN it will.



and With hessitation.. he wouldnt say when.. but did say it will be sometime this year.. hopefully, He assured me they know how desperate people are to get tuning products. Its not that they arent working hard to get the product to us. Its getting a product that is 100% functional to us that is importiant.

So in short..:

1)OUR CARS ARE MEANT TO RUN WITH THE STOCK INTAKE PIPING!!!!!

2)we can use aftermarket cams.. but dont go crazy.

3)K24s work.. and dont run lean.. but dont rev it over what hondata raises the rev limiter to on a K24a2 TSX.

4)It will be here soon.. CHILL OUT PEOPLE..

(I still got Greddy Emanage Ultimate and VManage.. but I will 100% change back to the original intake piping..)

The comments were made about one particular K24 setup in which intake headers, K24 and emanage were all simultaneously installed.

My suggestion was not to do everything at once. Start with the stock intake and K24. Dyno and measure the air fuel. Then swap to the aftermarket intake. It should measure the same as stock.

The air fuel ratio is determined by the airflow and pipe sizing around the MAF. There is a variation in aftermarket intakes. A well designed intake will keep the stock air fuel ratio and make more power.

A little more information.

We are working on a programmable system for the Civic.

1) It is our TOP priority. We have purchased two Civics for this reason.
2) It will not be called K-Pro

We know from the volume of email and phone calls the level of interest. More calls however, cannot make the development proceed at a faster rate, so please be patient.

What will? KPRO?

[caveman74]

good to know

[BLouIsGod]

everyone is going back to the stock intake tract lol.

[Excalibur]

as usual, x intake ftw.
Good info. I would rep you if I could. Thanks for covering more than just kpro. It's nice to know that I could run tsx cams if needed.

[Zeuceone]

Lol. Now people will praise the stock intake.
And bash any aftermarket intake.

[I<3MyHonda]

sooo this is for the K24, not us with a K20Z3...

No, this is for us.

See a trend?

[sheek360]

so a car with a mass air flow sensor cant possibly run lean? or after the reflash the si wont run lean? im sorry dude but i had a hard time understanding u

the MAF will automatically adjust thr fuel for the amount of air coming in as long as the stock piping is being used. The MAF was calibrated for the stock intake piping so i tcan adjust accordingly when it see's its needed.

I'm assuming that means no modding of the maf vanes then or what?

[NitrousG35]

While the OP's writing style makes it a little difficult to follow, I have gleaned this from what he said:

1. Our MAF sensor, as long as we use stock intake piping, will make adjustments in the Air/Fuel ratio.

2. Running cams like the TSX, will probably be the best cam mod. We need to be careful when running very high lift and duration cams with higher overlap.

3. There is light at the end of the tunnel: K-Pro is coming, sometime this year. Well, miracle of miracles.

OP, thanks for posting this. It is good to hear about what works and doesn't work.

So Hondata said to use the stock intake, but their site says you have to have mods to get good results from the reflash. We know exhaust doesnt really do much, so a header is the only thing left. Is Hondata saying that a header is all that is needed to reflash? Unless it's a race header, it won't have much in the way of gains anyway. So we need a race header (illegal), stock intake, and any exhaust (OEM or aftermarket) to get the reflash? Or do we need what they say on the site, at least an intake?

I think the gist of what the OP said was that if we use the stock piping with our MAF sensor, the MAF will compensate for increased air velocity. So, an X factor type intake might be the best at the moment. Couple that with a header and cat-back and you will make the most of a Hondata reflash.

[Whocares05050]

Good info.

[klk15]

so like always X's intake FTW!!!

[MJ23FE]

Great info!!!

Sounds like they are going back and foward...


From this post:

1)OUR CARS ARE MEANT TO RUN WITH THE STOCK INTAKE PIPING!!!!!


Taken from Reflash - K20Z3 06/07 Civic Si

You must have a minimum of an intake or header.

It is not designed to work with a stock 06/07 Civic Si and will lose power between 4500rpm and 5600 rpm if installed.

The 06 Civic employs a mass air flow sensor that automatically adjusts the air-fuel ratio for increases in air flow from intakes and race headers. Race headers will not cause this engine to run lean.

i dont know what to believe anymore jeez every week there is a diffrent post. Stock piping FTW, wait injen adds 15 WHP, wait X-INTAKE come on what is it already lol
