I want to learn more about the Kpro kmanager and its functions.
The readme files supplied with the kmanager are somewhat good, aswell as the short video tutorials. However, I would like to find a "walkthrough" for tuning a s2000 video. Ilittle more explanation behind all the stuff and preferably recorded during tuning.
I have a grip of the basics but I also have loads of questions poping up and things that I feel unsure of when doing stuff on my own. With the general low knowledgelevel of s2000s and Kpro here in Sweden I feel that much knowledge is needed on my part for a successful result.

Do you guys know any tutorials out there? Youtube didn't show much, neither did the search on these forums or the FAQ section.

 

I'm not sure if the videos on the CD are the same as those on Hondata's web site, might be worth a look. Tuning an S2000 is basically the same as any other K-pro, except with the S2000 you only have the zero degree cam tables to tune as opposed to all of them with the K-series.

I have had some problems with the fuelmaps for my s2000. As I started the tuning the maps were some basemaps and I wanted to change the columns of the fuelmap to support a wider manifold pressure.

However, trying to increase the rightmost column to say 14psi (which is over my running conditions) didn't work. It says there are other columns with a certain value that you cant excess. However I found no way to display these other columns, and ended up deleting column 10 over and over to get new ones with higher numbers on. Is this some sort of error or the way it is done?

How much extra room is good to have for the pressures in the map? Rpm is by default up to 11000. And like most other s2000 of european origin I am running 9k maximum. Would 2psi (when running the 10psi range be enough)

 

Figured out the above question. I managed to build new columns by deleteing old ones and inserting new ones even if the ones i added suddenly were removed by Kmanager again. Turned out I had to choose "show 3 bar tables" for them to remain visible.

 

When preparing for a new tune, when you know that you will want to boost say 1bar, should i then just take atmosphere pressure + 1bar boost (basically 2 bar) divided with the number of colums I use and spread the manifoldpressure linear over the colums?
For example: 150mbar - 300mbar - 450mbar all the way up to 2,2bars (having 2,2 as max but actual max boost will be 2,0 just to have it safely inside the chart)

Is this a good idea or should the manifold pressure not be linearly spread across the columns? Looking at the tutorials the charts seem to be using smaller steps for pressures under atmosphere and very few columns for the boost. Whats the reasoning behind this? Are more values needed for finetuning the usual drivinareas of the map? (Better resolution?)

 

I'd say your correct about the resolution, you spend alot more time cruising around in vacuum then in boost. I typically don't edit the load break points unless I'm having trouble hitting an AFR, (this is not very often) Hondata's "stock" ones work well in most cases. Be sure you have the correct MAP sensor for the amount of boost you will be running as well (ie. if you want to run 1BAR of boost you need at least a 2BAR MAP sensor, 1BAR in vacuum and 1BAR for positive boost pressure). If you run higher boost than the MAP sensor is able to read the brake points and associated fuel/ignition values are not being used.

 

ok here is k auto fuel and a write up on how to use it. this will help you get a constant 14.7 cruise a/f which is ideal for interstate and through town at a constant throttle.

hope that gets you started

 

honestly the kauto fuel works great ive used it before. which even magnesium liked it and he has tuned 100s of rsx s so i dont see why it wouldnt work for the s2k. if i had kpro in my car already id give it a try. or if you want follow the directions to kautofuel send me your datalog and ill make sure that it reads right and dosent look completely retarded

 

Currently using a Sience of speed 3bar sensor. Was a drop in replacement apart from minor grinding on the connector. Think they made it completely plug and play swappable nowadays.

Thanks for the links Nick, will check them out.

Ok I will keep the resolution for the lower pressures, but what about the boost area of the map? Is a column every 300mbar enough then? Or is there no real rule of thumb? Just try and see what works?

 

i have a SOS 3 bar map sensor too

in kpro, do you just select any 3 bar map sensor from the list?
