Hey guys!
New to the 11th gen Forums, but not new to Honda's or the 10th/11th gen platform. I thought I would make a short introduction and also post about our new FL5 Tuning progress so far. We have just become a vendor for the forum as well.
I Have personally owned 2 Fk8's, Two 10th gen Civic Si's, and I currently have a 2024 CTR and a 2018 Honda Civic Sport 1.5 Hatchback. The Sport Hatchback is actually my wife's project Time Attack car that she plans to compete with in the Gridlife Touring ClubTR class. Although not related to this platform, I currently race an 8th Gen K24 Swapped Civic Si Coupe in the Gridlife Touring Cup series ( for anyone who follows GLTC). Our First FK8 that we bought back in 2017 at one point was one of the fastest Time Attack CTR's in the country at that point. We actually plan to run our FL5 in the Gridlife Street class next year if all goes to plan!
We have been tuning using Cobb software and the Cobb Accessport for nearly 10 years now for customers, and longer than that for my own personal cars. While I do tune a lot of Honda's, our biggest market is the Ford Focus ST, Focus RS, and Fiesta ST. We have tuned nearly 10,000 of these cars since 2015 using Cobb software with great results. There is a big chance that we have tuned cars on this forum already for people who have had an ST or RS before haha.
We purchased our 2024 CTR back earlier this year with hopes to support and tune the car using Cobb software once it was released. Support has been out just over a month now and we have been VERY happy with FL5 support so far.
On top of all of the features that Cobb already advertised such as Launch Control, Flat foot shifting, and Burnout mode. We have already figured out many other things such as:
-Ethanol tuning ( true flex fuel isnt available yet, but will be eventually)
-Boost by gear
-Adjustable Power levels, boost levels, and throttle response per drive mode
-eliminate rev hang
- much much more!
Another big thing that I'm sure a lot of people have questioned would be compatibility with upgraded Pumps and injectors. I am happy to say that we have already been working with XDI, and we have an XDI Evo Pump and 1400cc Injectors in our FL5 right now, and everything is working great.
For just a little timeline on our car so far, as far as tuning is concerned. I have attached a few dyno charts below as well.
-We at first did a few baseline runs. The car made 292whp with no modifications other than a PRL drop in air filter.
-On the same day, we installed a Cobb Accessport, and right off the bat made 321whp with the Cobb Off the shelf Stage 1 93 octane tune
-Also on the same day, we put in a good bit of time on the dyno custom tuning the car. We got the car up to 348whp safely on a VERY hot day with ambient temps up near the 100 degree mark with high humidity. The car made over 350whp on a few pulls, but the 348whp run was the best all around pull.
- Fast forward a couple of weeks and we decided to fill the car up on E30 and put it back on the dyno. However, because i didnt want to deal with the crazy high Manifold air temps, we went ahead and installed a PRL front mount intercooler. On that day with custom tuning, we safely brought the car up to a respectable 391whp. These are gains of just at 100whp over a stock car, with less than $2000 in modifications, and while still keeping things safe.
This brings me to my next point, the cost of tuning the car on Cobb.
We currently are offering custom tuning with Accessport packages for just at $900. $900 gets you a whole lot for your money. Our tuning prices may increase eventually, but we dont plan to any time soon.
This Price includes the Cobb Accessport, The Jailbreak/unlock, next day air shipping on your ECU while being jailbroken, and our custom tuning. We do have an in-house dyno at our shop here in Georgia, so dyno tuning is an option as well for just a little higher cost.
While we also offer custom tuning Via Hondata, and we are a Hondata Dealer/Tuner, I do think the Accessport has a few advantages right now. Primarily those being Price, the jailbreak process, the Accessport itself is a very nice device that can do a lot of things, and ease of tuning remotely. Datalogging for custom remote/ email tuning is very simple with the AP. Its just the press of a button. No need to ever have a laptop in the car.
If you are interested in an Accessport and/or custom tuning for your FL5, DE5, or Even your FK8 please feel free to reach out with any questions you may have. You can PM me, or you can send me an email at [email protected]. You can check out our website and tuning/ AP prices at the link below as well.
Thanks!
