tuning

Hey y'all. Things have been going swell with my Si so far. But I ran into an issues last night. No check engine light, but my car is only hitting about 10 lbs of boost at most. I am on the ktuner 21psi starter tune. Mods are my PRL Cobra and PRL Catted DP. I am getting a more raspy sound from up...

So I have a situation. My car was totaled (t boned by a deer lol) and ended up having to replace a lot of things. I ended up getting a catted skunk2 racing down pipe (and I have a magna flow cat back I got prior to my accident). I think I’m gonna get hondata because my car keeps shooting...

Hello All! i’m new to the 10th gen platform. I was wondering what the best method for conservatively tuning my car would be. I have a ‘19 si. What I mean by this is, I want to get rid of rev hang and enjoy the benefits of tuning, without risking the longevity of my motor or my clutch. I’m not...

I apologize in advance, I know I'm going to get flamed for this thread since there's a ton of threads out about tuning. I've gone through the tune experienced thread, TSP / phearable threads on how great they are. I'm super new to all of this (not an excuse) but definitely still very...

I have a 2017 FK8 that is essentially stock as far as engine and performance mods go. I plan on having fun and learning a lot upgrading it little-by-little, and one of the first things. I wanted to start with is a tuner that I can grow with to make the most out of each future upgrade. I've...

Hello Everyone, I was looking to tune my FK8 on full bolt-ons and on E85. I was wondering if anyone knows any guides out there on the parts required for different stages / supporting mods. Additionally I was wondering if there are any Remote tuners that you guys can recommend to me as well as...

Currently I have 85k mi. I've owned this car for 6 years now. I received the first blue one in Michigan (as far as I know). I have my first real problem. Upon turbo spooling, it halts, stutters, and if pushed, will give me a christmas tree of dash lights, putting the car into limp mode. I have...

Greetings to all, I am in an extremely unfortunate situation. After I attempted to flash my 2017 Civic Hatch back to its factory tune, the flash failed, after which my ECU went into recovery mode. After two hours of reflashing, unplugging everything including the battery, and plugging everything...

Just installed a high-flow cat and did a full custom tuned since I'm now FBO. This is the first car I've had that I've gone this far down the rabbit hole with parts and especially a high-flow cat. The main question I have is if it is normal for there to be a more pronounced exhaust smell almost...

Hey all, recently installed a PRL Cobra with Race maf, and retuned with TSP's stage 1 (race maf.) I've noticed my fuel trims are way out from what they use to be on just the Tsp stage 1, stock maf. I've also noticed a sizable increase in Kcon rise when doing any highway pulls, typically above...

Hello everyone, its me again. Last week I finally managed to upgrade my halogen headlights to LED headlight units. It wasnt without a struggle, but I managed to do it (with some help from you guys) This month I dont wanna buy anything crazy expensive, but I would like to swap out my side...

So as the title suggests, I'm trying to trade my FC3 for an FK8. Since my Honda mechanic friend installed the PRL flex fuel kit, I'm not sure how to take it off. Is it possible to flash back to stock with it still attached? Or Can I just leave the flex fuel tune in place and hope I'm not on the...

I recently bought a PTR Flex Fuel kit for my 21' Hatch. I was wondering, once I install it do I need to tune my car right away ? Or am I able to leave the kit on my car, still running the phearable 1.5. and a couple months down the line, get flex tuned whenever I feel like it ? The kit has been...

Hi, This has been my go to place for my civics related questions, you have all been very helpful. And I dont wanna spam this forum with stupid questions but sadly, I cannot find the answers to my questions anywhere. So I end up having to ask here, grateful for all the answers btw! So I will...

Hi, This might be a stupid question with a very simple answer. I am ordering a new pair of front headlights, gonna replace the whole thing from halogens to leds. I already ordered a pair but it was not delivered due to a system fault at amazon, so I will order from some place else. But a...

I have the hondata TCS turned off with the cruise control main but since ive installed some new parts and a tune. Ive noticed it kicking on while doing hard pulls in 3rd toward the top end and the wheels start to spin. Is it normal for the system to kick on like that even when turned off?

Hey everyone, Long-story-short, I've never had much experience with cars, but always loved when people modded them. I'd like to do everything myself so I can really get to know my way around them. I'm picking up a Gen 10 within the next month; either the sedan touring, or the Hatchback Sports...

If I’m running the ktuner 23 psi basemap, will I be fine installing the flex fuel kit and disabling the parameter? I’m not going to pump ethanol yet (I’ll just be on 91) but is it fine to have the flex fuel kit installed while on the basemap?

I’m ready to start some mods on my car now that I’ve had it for a few months. I’m a little new to performance upgrades. Suggestions on where to start before a tune?
