Project 8th Gen Civic Si - Hondata Flashpro Dyno Tuning How To 

Tell me bout tryna understand everything for hours

These cars are a lot more picky about their tunes. Some reason German cars seem to be able to run strong and reliably off of OTS tunes but Honda base maps are pretty crappy

My pleasure!

Thanks - Injector duty cycle actually hit 92% at redline - I meant to talk about duty cycle in the video. I am definitely going to tall about it in the next video tho.

I agree that would be a good video. I have to see what manifolds I can get my hands on. I only have an RBC atm.

Mee too any problems so far?

@@Steve-zo4uc Not really! I have a k24A1 in mines and the oil leaks are annoying but thats it

Thanks - Glad you like it

you should not

Great video nick! She made good power, I'm going to switch my intake to the cold air and a few others when winter is over then bring it by.

Thanks - Sounds good - lmk when youre ready and we can touch up the tune for the new parts

; )

@@tuningbynick I have 2013 Honda Civic 2013 Auto LX only mod so far Takeda Cold Air Intake what recommendation to get it to got faster new to mod scene. What's the best quiet not noisy for tune exhaust that good for street daily driver? Also what bolt on will I need wheels etc tires to get most fun out of car...Already have Tein Coilovers also.

If you have no CAT you can technically get away with AF's that lean

That should make for a great project car!

Thanks. Yes I do. Shoot me an email and I’d be happy to discuss- nick@tuningbynick.com

@@tuningbynick awesome

@@tuningbynick e tune services awsome man will keep you in mind when I'm ready if you willing to etune my fa5 with bolt ons running hondata flashpro

Thanks - Id be happy to discuss some options with you, shoot me an email and we can figure something out - nick@tuningbynick.com

Thanks - I always switch to speed density whenever i am tuning- i forgot to mention that in the video

At light load the 14 is good - the 13 is a bit lean for WOT - The proper target AF for an NA K is 12.5 at WOT

Almost everything is adjustable if you have a Hondata Flashpro - Yes there is a method of finding gains, but its not a simple thing one can do. Tuners like myself have spent thousands of hours perfecting our craft - The best thing you can do is take your car to a reputable experienced tuner and work with them to get the most out of your car

If you are CATLESS if not I wouldn't!!

@@416rides5 you need subs that bad?

Im lost the comanded AFR over 4.5k RPM

In all honesty i have never tried adjusting the "corrected" value. In my experience, you always have to question wideband readings. You can never blindly believe what they are reading. If 2 sensors are showing different values, one of them is not working correctly and should try and determine why they are reading differently

@@tuningbynick Agreed Nick BUT the "corrected" AFR is an offset reading of the stock WB sensor as can be seen in a log by displaying both AFR display and corrected AFR display, this was done by Hondata by reading a known good stock sensor then applying a correction factor to give a display reading much closer to the actual AFR then the stock sensor shows in a richer than stoich condition. For instance having both displays up in a log under closed loop will show (in my case)14.7 AFR and 14.9 corrected AFR... then in boost 10.8 AFR is equal to 12.15 corrected AFR, as the AFR goes richer the offset becomes larger. Under lambda settings you can choose to target the corrected AFR reading when using the lambda overlay functions on the fuel map tables. Given the limitation on the stock WB reading under any/all situations logging an aftermarket WB is going to show 2 different values, choosing the AEM WB as long as it has been calibrated is the correct choice to rely on IMO. Surely you have a dedicated WB for the dyno when tuning that you trust the readings an can compare the stock sensor to? I'm almost finished wiring up the AEM WB harness back into the car, I will see if I can make a video with Hondata running live with all 3 WB displays running - AFR/corrected AFR/AEM input to hondata AFR along with the physical gauge readings, who knows maybe there is something there for video content you can film/discuss on your chanel?

No

Yes this was tuned using speed density fuel maps. You really need a dyno to be able to tune ignition timing effectively

@@tuningbynick Will speed density be OK in cold weather. I’m debating on turboing my R 18. I’m replicating pets and similar turbo size as the TSI turbo kit because hondata has a base map for that kit. However because I know all the parts won’t be the same I will need to fine tune the map. But again the ignition advance/ retard is like what!?! How do E tuners tune the vehicle tables specifically ignition if it’s a Etune?

When done properly - Tuning usually improves or at the very least does not effect fuel economy.

Unfortunately Hondata does not have a Flashpro for the LX - They only have for the Si

Hi Kevin - None of the basemaps will work that well for those parts - Yes i do offer etuning - send me an email and i would be happy to discuss - nick@tuningbynick.com

Not to worry - I know that is a very requested video so i will be doing it as soon as i can fit it in

Yes you can make all the fuel and all the ignition maps the same and make sure "All" is checked so that any adjustments you make adjust all the maps the same way. This will make your life a lot simpler

Ok thank you Nick very kind of you to share these tips

Thanks - The OEM clutch is surprisingly good, if they are in good shape they can hold a good amount of power - If its warn our tho, i really like the comp stage 2 clutch

Thanks, glad you like the video - I dont really share tunes because this tune wont run the same on someone else's car - I do offer remote and etuning services that can help to get your car to run properly. If you or anyone else is interested in that sort of help, please feel free to email me - nick@tuningbynick.com

For sure. Shoot me an email and I’d be happy to discuss options. nick@tuningbynick.com

Any humps or dips are usually caused by an air flow resonance within the intake system. Usually long vs short intakes will have these humps and dips in different spots. I should be able to see how the hump and dip move around with different intake air pipes when I do the intake comparison video.

@@tuningbynick what about changing vtec engagement. Every time I have been tuned I never had that dip 🤷🏽‍♂️

In all honesty I am not a fan of water meth kits. I’ve tuned countless setups with water meth over the years. It definitely won’t get you the same results as e85. Water meth won’t help make more power. It just lets you go a bit beyond what the knock limitations of pump gas and allows you to run more timing. That being said. If the water meth system has a failure. It’s usually catastrophic for the engine. By comparison - e85 is oxygenated and has a higher knock limit. Usually you can make more power on e85 just because it’s oxygenated and then also run more timing making even more power

The best thing to do is collect all your mods and then install then and then go right away for a tune - There really is no good reason to drive around on a basemap

@@tuningbynick Thank you!

These cars are open loop when in WOT

On a setup that specific you really need to actually tune it - If you dont have any local tuners you can take it to, i could remotely tune it for you

@@tuningbynick how’s the remote tune work?

Once VTC is adjusted you need to readjust your fuel and ignition tables otherwise you wont be getting the full benefit of your VTC adjustments

@@tuningbynick any tips on tuning short term trims? What targets am I looking for when giving 30-70% throttle whole normal driving 1-4 gears.

Best way to get in touch is email - nick@tuningbynick.com

That must suck

Was it done on a hot day? Iat Temps could have been much higher causing less power.

@@TheJanz3n nope it was probably under 20° and I have acuity CAI best one on the market

@@k24z7_ are you in Canada? Same sea level? Or did nick tune your car?

@@TheJanz3n I'm in Toronto and yes tuned by Nick
