I am on my 4th 8th gen Si. My 1st 3 were all bone stock. My current 09 FA5 had 42k miles on it when I purchased it 2 years ago (122k now). In the trunk was the stock airbox (K&N v2 on car), a brand new Mugen shift knob, and my very 1st Hondata Flashpro! I have read and researched so much on tuning... this video was by far the most informative. Thanks for taking the time to make this Nick! Question... I want to run 16:1 afr cruising on the highway in 6th gear. Is this possible? My 2 cents to you... lightweight wheels made a HUGE difference in accel and braking for me. Dropped 3.4 kilos per corner going with Koenig Hypergram 17x8 35mm offset with Michelin AS3+ 225/45/17 tires.

Could you just do this on the road by holding the brake pedal and throttle at various loads and data logging it? Are you adjusting timing for knock or to affect the afr too?

Ty very much for posting this. I am just starting to mod my 2008 si and i have the Skunk2 cold air intake and i getting ready to buy the header back exhaust from skunk2 as well. Because I live in Ohio and I have to do E-Check I'm waiting until I have all the parts necessary to do the build and I'm waiting until I can take my E-Check so I have leeway in order to get past it to do the build this was very informative and if you're down for correspondence I would love to pick your brain

Great information and content! Can you do something similar for your RSX as far as ECU options and datalogging? The challenges with the 05-06 sensors/ecu? Hondata vs ktuner? Thanks!

[@BulliKid]

Did u tune using speed density? I don’t get how you can set timing numbers. I understand fuel af targets but how does one know timing angles to set.

[@tuningbynick]

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

[@BulliKid]

@@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?

[@Nikko-zi3ti]

when you say vtec cut in at 4200, is that the lower or higher vtec engagement? or so you set them both at 4200rpm?

[@chrismetalwilson2588]

Awsome man great info and will give me a good base map to follow currently have about the same mods just different brands same sizes though so this should get me close. Thank you and now some datalogging and adjustments 😁

[@lcq4blackstar]

Thanks for the tips Nick! Is there an editable formula for the "AFR corrected" display or was it set and locked by Hondata? I thought I saw a formula scaler somewhere before to adjust this display against my AEM WB so that I could calculate it to an exact AFR reading when logging but am unable to find it now. I know I can go in and enable the WB logging on an input signal that is disabled under "lambda settings" but plan to get the "AFR corrected" calculated then remove the AEM unit from the vehicle.

[@tuningbynick]

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

[@lcq4blackstar]

@@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?

Hey nick, awesome video! I’m having an issue with my CSX Type-S with a K24a2 swap. It will redline at 8200, I have a type s pump, 50deg vtc. But sometimes it’ll just stop at 7 grand like a wall. Any ideas? I was told it was the clutch switch and or something to do with the flat foot shifting.

[@chrismorgan7020]

From the looks of the pre made maps and how lean they still are. If you are running with a high flow filter stock airbox and an axle back would you be slightly better off running a rai tune on the car just to be safe having it figure for slightly more airflow so you don't run lean? Or would you still be better off with a "stock reflash" from hondata?

[@way2sick562]

So with all those mods. Im guessing its best not to buy the hondata then? And get a tune?

[@kfitfactry]

Good video however why does graph dip down and then go back up?

[@tuningbynick]

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.

[@kfitfactry]

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

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.

Out of pure curiosity, I'd love to see the effects of water, meth, or water/meth injection on an N/A application w/ pump gas! Definitely on the expensive side for "testing" but I'd be curious to see if it's a legitimate alternative for us Canadians with minimal access to E85. And if the gains would be similar to E85.

[@tuningbynick]

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
