So I'm very new to the Honda scene as I only got my fg2 only a couple of months ago. My car currently has a K/N SRI and Invidia Q300 Catback running the K/N base map. The car is completely stock other than that. Could anyone help me by making a more reliable/optimal calibration for my car? I'm scared that running one of the Hondata maps will cause my car harm and I definitely don't want to do that. Thanks for any and all help!

Basemap for 2009 Si?
Re: Basemap for 2009 Si?
Welcome to the Honda/Hondata scene. You won't really run into problems with a Hondata basemap, you just have to be mindful of which one you choose. With the K&N intake, some like to be tuned on the MAF sensor and some are more responsive being speed density tuned. The main thing is to watch for knock if you're running 91 octane, if you have 93 or higher you would be okay to start on a Hondata basemap.
Do you have plans to add a race header or any other performance mods in the near future, or is this your combination into the foreseeable future?

Re: Basemap for 2009 Si?
I’m running 93. Really want to get a header but don’t have the money for one right now. Should I wait until I get a header before getting a real e-tune?
Re: Basemap for 2009 Si?
You're one of the lucky guys with 93, haha.
Definitely no reason to wait to get a tune, just gauging your future plans is all. There is a quick way to tune them and a long route, the long route takes 10-12 revisions or so to get dialed. That involves going in and tuning each cam angle one by one, then using that data to build out the tables and a cam angle map for what your car likes, not someone else's. The short route is less complex, usually can be done in 4-6 revisions. This route gathers less data specific to your car, and uses more of a general cam angle map. If you had a header planned in a few weeks or months, then I would recommend the short route for your time and money sake, because adding the header means you would need to retune it. Then I would spend say spend the time to tune it the long route once the header goes in. If you don't see the header happening for quite a long time, the long route would get you the best product and is a little more tailored for your car. Both are just as safe, just the long route gets a lot more data specific to your car and therefore yields a better product for you.
If you want some help tuning it let me know. And/or let me know if you have any questions on anything.

Re: Basemap for 2009 Si?
Yeah I would love some help tuning it. Honestly I don’t think a header is too far away so the quicker method probably makes more sense. Could you possibly explain the basics of how to datalog? Thanks again for all the help.
Re: Basemap for 2009 Si?
Sounds good. That works because the race header is the mod that impacts the tune the most, so I always try to gauge future plans before starting out on a path to tune them. So we'll go the shorter route for now, which will make it safe and fun. Then if you want my help once you add the header just let me know and we'll go in and tune it the long route to get the best product we can.
Attached is the first calibration for you, go ahead and load it up when you can, then make a datalog to get us started. As mentioned, the datalogs need to be in the twenty minute range with stop and go type driving. Avoid highways and long stretches of steady RPM basically. On the drive, make one WOT pull in third gear from 2500-8600. If you want the rev limiter lower just let me know, 8600 is the accepted max for these engines, but if you want it lower just let me know. It's your car so you have control over anything we do.
Are you familiar with how to load calibrations to the ECU?
Here is a good video from Hondata on how to datalog, https://www.youtube.com/watch?v=IMyLKSx6Te8
Download and save this calibration, then upload it before your drive. If you aren't too familiar with flashing the ECU, the one main point I can give you is once the green status bar starts to show the percentage of completion, make sure you don't turn off the key for any reason. Sometimes it will go forward and back a little, just let it run. Turning it off while flashing will corrupt the flash, so be patient.

Alright when I get off my shift in a couple hours I’ll go ahead and load it up. Thanks.

Sorry for the wait. When I got onto the highway I wasn't able to accelerate from 2500 but 3000ish instead.

No problem, it looks really good actually. I made a few part throttle fuel changes, and it wanted some extra fuel in vtec which is good. Take this one for the same type of drive when you can, we might be there already.

Re: Basemap for 2009 Si?
It looks really good, pretty much everything is dead on. Go ahead and make another datalog tomorrow sometime, and we'll see how that one looks. I like to make sure they're good over multiple days.
What is the ambient temperature from this last datalog, or the earlier one?

Re: Basemap for 2009 Si?
The gauge never got over halfway on the dash. Thanks for all the help today, I’ll be sure to do another log tomorrow. Btw, the car definitely feels quicker than when on the Hondata basemap, what kind of performance gains do you think I got overall?
Re: Basemap for 2009 Si?
I was curious about the outside air temperature, sorry. Was it a cool day, or was it warm? Just curious because of the air intake temps is all.
The pull in that one doesn't look to solid when running through Virtual Dyno. When you make the next datalog, try to find a really flat and smooth stretch of road somewhere, then make a couple third gear pulls so I can run them through Virtual Dyno. The software works pretty well, but it's very sensitive to uphill or downhill roads, and bumps in the road.
Glad it feels good though. Once the race header goes in, it really opens things up.

Re: Basemap for 2009 Si?
I live in Texas so it was a pretty warm day. High 80s I’m guessing.
Re: Basemap for 2009 Si?
I see, yeah the intake temps were in the 110* range on average. So with the placement of the filter on the K&N intake it will return hot intake temps almost all year. When you get into the "Texas heat" days, the intake temps will be very hot and you will lose a lot of performance. I just wanted you to keep that in mind is all. I don't know how attached you are to the K&N intake, but if you switch to the Hybrid Racing, Skunk2, or K-Tuned 3.5" CAI's that would really help performance in general, but help keep the temps a lot cooler on the really hot days. K-Tuned make an SRI that puts the filter behind the headlight, just in case you don't want the filter behind the bumper.
At the end of the day which intake you choose is none of my business of course, I just want to point out the hot weather issues while you're driving around with the AC on in Texas. When the temps go up, the ECU pulls fuel and timing to keep the engine happy, which causes a loss in performance. Either way though, we'll make it as good as we can once you add the header if you still want my help.
