Update. Ya'll might find this one interesting.
So since my dyno day...i have been experimenting with different Maps. A member on the K20a forums(kinda a tuning guru for these engines) took a look at my MAP from the dyno tune and immediately pointed out some less then ideal areas.
One problem i had was vtec crossover. at 4500rpm the car would engage vtec and immediately fall on its face for a split second. Total torque drop/cut. Then it would pick up and take off. Not ideal.
K20 member found the issue and corrected it then sent me the map. It was night and day better. Smoooth as it should be.
He has now taken over tuning my car. I have logged 10 different maps from him so far, and sent back at least 20 logs by now. Each revision the car is pulling even harder, all the way to 9000rpm...and he says we havent even added power yet. Thats at the end.
He has sent me 3 maps with different ignition values, then 3 maps locked with different VTC cam angles, amongst other various maps. He overlays everything and looks through it to find the ideal values. Scientific approach and very efficient / professional. Guy knows what hes doing and he shares/explains every change he makes, and why hes making it. My favorite comment from him so far "I have more to offer you for your top end, but we will get to that near the end of tuning".
Guy lives in germany so theres a 6 hour time difference but its been working out no problem.
Vtec transition is extremely smooth now with no delay, no torque drop off. No weirdness. I told my honda buddy/local tuner about this. He wanted to see the fixed map. I sent it to him and he couldnt see where he had gone wrong. Once i read him the email from the k20 guy, right away he goes "yup. Thats my bad. my mistake. Simple as that i messed up there. Tell your k20 buddy thank you for pointing this out as I mightve never found it. Super not obvious mistake".
My honda buddy was blown away at how quickly this guy found this error and corrected it. I guess this just proves that platform tuners exist for a reason. It matters. K20 forum guy has tuned 100's of k20s NA. He knows these engines/ecus inside and out both in race/track trim and street trim.
The car feels fantastic now. Making good power. I logged 6 maps yesterday. All on the same road, starting at the exact same starting point, 2 wot runs for each map.
his "extrasharp" ignition map felt the best to me and i told him this. He then explained that the data shows that map was definitely the fastest. Apparently there is some timing headroom left as well.
I will definitely have the car loaded onto the dyno once the tune is completed. Would love to see the differences. It feels like a different car yet again lol.
As for cost...i have asked him for pricing like 3-4 times now. He just ignores the question and keeps sending me maps lol
