Hondata

Hi everyone,
I recently purchased flashpro for my 08 civic si and I'm looking for some help making minor adjustments to a basemap to ensure my car is running safely until I install my bolt-ons and get a proper dyno tune. The car is stock except for a ... test pipe and a skunk2 2.75" exhaust. Below I've attached the calibration that I'm using at the moment (Hondata stock "tuned") and a datalog. If anyone is willing to help me smooth it out and keep the knocks/afrs in check I'll send some money your way for your troubles. Thanks.

I can help you with it if you'd like. Overall it doesn't look too bad. Are you wanting to keep using your file, or are you okay with using something tailored more for your car and cleaning things up that way? I just want to make sure you get what you want.

I'm guessing you run 91 octane based on what I see, is that true? Do you plan on adding an intake at some point, or are you sticking with the stock intake?

Hello, thanks for the reply. I don’t mind using a different file as I just pulled this off one of the provided maps. Really the only thing I’d want to keep from this file is the 3500rpm launch control, removed rev hang, and a rev limit around 8400. Yes I run 91 octane. I plan to keep this tune for a few months until I get an intake and race header, and by then I’ll be getting it dyno tuned.

Yeah no problem. I put together a file for you to start on. I changed the launch control to 3500 for you, rev hang I always turn off, and I moved the rev limiter down to 8400 for you. If you want the rev limiter lower or whatever, just let me know. Double check those settings in the file to make sure they are as you want them so we are on the same page.

Looks like you already know the datalog protocol pretty much. But shoot for 20 minutes or so just like you did with the clean WOT pull in third gear from 2500-8400. Then post the datalog and we'll see what it looks like.

I generally like to tune these the long way, but since you plan on adding a race header and intake in the near future we'll use a blended file to get you dialed for now. When you add the intake and race header, I can help you retune it if you want, or we can make it good for you to drive on until you get to the dyno. All up to you, just let me know in the future if you want.

Anyways, take this file for a drive and we'll see how it looks when you post the datalog. It might take a few revisions to get it dialed, but it should be pretty good from the start. Don't get too aggressive with the driving until we get through this first datalog. I would want to clean up any big chunks before you get after it. On the next revision though, you will be free to drive it however you want.

Thank you for this! I’ll flash it on tomorrow morning and post a datalog shortly after.

Sounds good. You're welcome.

Here's the datalog for that file you sent me. Afr's seemed consistent but the vtec was a bit sluggish, maybe it could benefit from being raised higher? I looked over the graph but am still not really too sure how to analyze knock.

No problem, the first one is always ideal, the main thing is getting in the ballpark which we did very well. I made some part throttle and WOT fuel changes. I also changed up the cam angle map some based on the prospect of your car liking the 45* cam angle.

If you look at your overall knock count it was 1. Not sure what display you're using, but you can see it there. We had one knock right near redline in the normal area of sensitivity. I adjusted the ignition in that area to remove the knock.

I also moved vtec up to 4350. That is where you had it on your old file, and your mods might allow that.

Take this one for a drive. Since I changed some cam angles, still keep it to one WOT pull in third gear so I can see hot that worked. So let me know if the vtec crossover feels better. Cam angle mapping is very important, which is why I usually like to do this the long way to get data. Since you place on redoing everything in a few months, we would have to do it all over again for those mods. But see how this one goes, if you still aren't happy we can switch to the long route on doing this to see if that gets you where you want to be. Here is the next one. Same datalog and driving style including the WOT pull from 2500-8400.

Ok, will give it a try tonight.
Btw, do you have a PayPal or Venmo? You’re doing me a huge favor and I don’t want you to work for free.

Sounds good. Sorry, I meant to say the first one ISN'T always ideal. Haha. The fuel can be a little off in the first one which can make the vtec crossover and other areas a little off. Your test pipe seems to flow well, which I wasn't sure of and started you on a more conservative cam angle map in the first file. But I added some angle and moved the vtec rpm to help it now.

I'll shoot you a PM real quick.

This revision feels really good! The powerband is very useable and doesn't feel sluggish at all. No knocks either.

Yep it looks really good! That's why I don't do one calibration and send people down the road. It takes a couple revisions to get it good, the first one is just something to get us into the ballpark. I made a few part throttle adjustments to tighten up the fuel trims there in this next one, and I added some fuel on the WOT pulls to get our AFR dialed. We should be just about there on this one for you. Feel free to drive it however you want, just be sure to get the clean WOT pull in third gear like you have been. Other than, feel free to drive it however you want and we'll see how it looks.

Glad you're happy with it!

I got on this one a lot harder and it seems to do well. Looks like the afrs were less lean at WOT which is nice. My hondata app counted 1 knock however I did not see it on the datalog. Let me know how it looks, unless there are any major issues I'm pretty happy with how it feels!

This datalog is the same as the previous one. You might double check the FP memory to see if you can find the one from today. I double checked and they are both the same.

Sorry about that I must have mixed them up. Will look for the correct one tonight after work.
