Hi guys,

Well, I was about to launch my car for the first time to check how much it was making and I got very, very disappointing results.

Currently, I have the following mods:

- TSP Stage 1 with ktuner
- K&N oiled air filter with stock intake box
- PRL intercooler
- Custom 2.5'' exhaust system.

I got 170hp to the engine and 300Nm of torque.

Even less HP than these cars are making stock!

But the graph and data was odd.

At the time I just thought there was something wrong with the car or the tune, but outside of the dyno, the car feels awesome, and way more powerful than stock and much more refined than with the starter 21. So it didn't make any sense. I disabled the VSA completely with the pedal dance before the run and changed to the map 3 with the multimap setting on ktuner.

After talking to the guys at the club, @kytos pointed out that it might have been the AVSA option pulling back or cutting ignition and hence the weird results. WIth the nerves and that being the first time any of us ran a dyno ever since that option was implemented on ktuner I didn't realize at the moment.

Does that make sense, @KTuner?

So kids, remember to enable the main option to disable the advanced vsa before doing a dyno run.

I have never mistreated the car, no engine DTC codes ever.

I will launch again this week and see if I get good results or if THERE IS something wrong with the car after all.


EDIT: Final stats ->

235BHP and 386,86Nm

As stated here Advanced VSA is still doing it's job even if the pedal dance is done, if the rear wheels are static (2wd hub dyno) aVSA is trying to pull timing accordingly. We will dyno both civics this week, let's see what we find :)

Sooooo nice results , bravo! I love the IAT2 that stays steady throughout the pull, I think I'll be ordering my Mishi sooner rather than later :)
You were dyno'ed on quite high altitude / low atmospheric pressure, so max boost was 21'ish , but dyno doesn't care, it will adjust
this is power at the wheels, right ?

Very bad weather but the dyno is well calibrated tho the max boost is reduced. The power at the wheels is 226whp, graph is measured to engine.
