Anyway, if you're really into it, check my write-up of the Hondata seminar and perhaps a long post I did on a day of tuning at Hondata. If that is still not enough, I also wrote some 10,000 words on the K-Pro and K-Pro tuning which I might share with interested parties.
i've been through your available readings already (i like to do my homework, when it come to my car)

i would love to see what else you got, if you're willing to share

I just made the document "The Hondata K-Pro ECU" available for download. The link is at the bottom of the FAQ. It's a work in progress but may give you some additional insights into the functioning and tuning of the K-Pro.

superb exposition of the features of kpro conrad!

the hondata programmable ecu is a very very clever product as it invites 'exploration' and learning

u have to work it, understand it and it will then reward you

its not a quik fix instantaneous in your face solution but depends on consumer interactivity

and this leads to an extended life cycle as it evolves thru application and usage

mutability and adaptability is the key to longevity in the market

and as a consumer one gains confidence from such flexibility and reactivity to real world testing and experience

it really is the ideal product in this respect and fascinating in its own right, i cant help grin with my custom flash everytime i hit 3rd gear at wot!

i know ur background is in computing and u have adopted the kpro as an object of deep research and testing-long may it continue!

Does anyone know why someone would chose the 8100 rpm limiter over the 8600 limiter. I've read a ton of the posts and can't seem to find the reason. I read that if you hit the rev limiter that it's bad for the engine, so the 8600 would seem better, so why would someone want the 8100 reflash instead? Is that less detectable or something?

Mmm... only reasons I can think of would be:

1. Safety. Let's face it: Honda set the rev limiter at 8100 rpm for a reason. We all know and trust Hondata to say that the engine is fine up to 8600, but for some people they just don't want to risk it.
2. Warranty. I am not 100% certain, but I *think* that a Honda tech can plug into the ECU and get some readings about how the car was driven for a limited recent time period, including the max revs the engine hit. If you go in trying to claim warranty work because your rings are shot, or you blew a piston, and they can show you've reved the engine past the accepted red line, you're basically SOL.

Personally, I have the rev limit at 8600 and love it. I dont hit it everyday, and I try to make sure that I don't bounce it off the limiter (I haven't off 8600, but I did once or twice off 8100).

It's a personal decision. Playing it safe or just playing.

Peace

WhiZ

Hi Conrad, do you plan on adding some pics (like fuel maps, GUI stuff) to your work in progress doc? I know the Kpro DVD and training video probably have those already, but it will be nice to have that in your doc too. It will give some novices like me who don't have a Kpro yet but plan to get it in the future have a better feel on the Kpro.

That's a great idea. My big K-Pro document started out as just a set of personal notes and then got bigger and bigger. It's pretty technical and dense. I definitely plan to add a section with various "How-to's" that include images and screen shots. Sections could include a step-by-step "How do I identify and remove knocking?" and "How do I log my air-fuel ratio and make corrections?" and such.

just go to hondata and download the K-manager. you can play with the maps while you watch their videos.

I can run K-manager without hooking it up to the ECU? if that is the case, i will try to play around and get a feel of K-pro. does the K-pro software only run on the XP? I'm still using Win98 and Win2K. Thanks for the advice.

K-PRO, the only customizeable solution to anyones specific list of mods.

Yes, you can run the ECU Manager software without being hooked up to the ECU. In order to practice, you'll also want a couple of datalogs (some of which have been posted here). That way you can practice analyzing logs and making tuning decisions based on what you see in the logs. I should probably add a few brief sample datalogs to the FAQ.

I tried to address this question in the FAQ:

I am really confused. Should I get the reflash or the K-Pro?

Here are the pros and cons for each:

Hondata #4: A tried-and-true reflash that works with most cars. It brings a bunch of extra power in the midrange by moving the VTEC point from 5800 to 5200, and it adds some on top. It is a relatively mild tune. It has to because once it's in, you can't go and fine-tune in case you have knocking. You can also have it reverted to stock by Hondata should the need arise. One problem: it may not work optimally with your particular setup. I had a distinct power dip with Hondata 4 and my Icebox. That's because each I/H/E combo has different air-fuel characteristics and Hondata 4 is one-size-fit-all.

K-Pro: This gives you complete and total control over your ECU via a daughterboard and a USB connection to your laptop. You can monitor 42 datapoints at frames rates up to 20 frames per second. You can change fueling, ignition advance, cam angles, fuel cut-off, VTEC, and tons more. The calibrations that come with it are quite aggressive and you'll likely have to play with the settings to get rid of initial knock, and Hondata suggests you have it professionally tuned. You'll need to learn a lot about not only the software, but about ignition, fueling, can cam timing concepts. If you're game, the K-Pro is endlessly fascinating, you'll never outgrow it as you modify your car, and you'll learn how it all fits together. However, in order to revert to factory stock, you'll have to undo the whole thing.

Those who have a CAI and don't want to mess with the car or learn new stuff should go with the reflash. All others will be much happier with the K-Pro.

I've just begun mod'ing my car and I can't see myself going too crazy in the near future... matching my AEM CAI with header and exhaust is about it. With that typical setup I'm assuming, from what I read, that the reflash would work best.

Any arguments?

No argument. The Hondata #4 reflash works great with a CAI, and your investment is totally protected as Hondata will give you almost the full price of the reflash off if you decide to upgrade to the K-Pro in the future.

Well, Conrad knows the most about the K-pro, but I'll argue and say the K-Pro should give you markedly better results with its more agressive timing increase and the option of the dual Vtec window.

You are right. The K-Pro will give better numbers. But he asked what the best option was for someone who just gets started and doesn't plan on going nuts with mods right off the bat. For someone like that the reflash is a great way to get performance while getting to know the car.

True. Just remember, Maverick, most of "couldn't see ourselves going crazy" with mods when we started. Give it some thought and consider what you may want in the future.

Thanks guys... 4thGenTeq, Trust me, I know what you mean. I've been spending hours on this site daily reading up on just about everything and constantly adding to my wish list. I gotta start somewhere though, right??

I appreciate the responses

And as a sidenote, From what I've been reading I agree that going K-Pro is better if I ever consider adding more mods in the future, however as Conrad said, if they can take off the price of the #4 when/if I update to the K-Pro, then my money was well spent.

say the kpro will handle up to 12ibs of boost right now? when will kpro be able to handle more? will the sensor cost more?

At some point Hondata will support a 3-bar sensor with the K-Pro. I don't know the specifics of the installation or which sensor they will support.

Like Maverick, I am just getting started also. I am considering Reflash #2 or #4. I like the "safety" margain of the #2, but will probably go #4 because I will always wonder what 8600rpms would be like! Anyway, other than a lower VTEC point, does the Hondata upgrade change anything else over the stock programming such as A/F ratios, timing, etc. to get more power? Is it simply a lower VTEC point and a higher redline? That seems kind of simple for $600, no?
