Official: Dyno Chart Comparison & Calibration Registry

Donk know if he is here but he was active on tsx and some other forums.



At this time I was average stupid person who didn't know what logging is.

He is Ukrainian and he likes to play war card lately but in reality he lives in Canada for past 5+ years.
I have went down the rabbit hole to find more about him so I have talked to people from Ukraine who are in feald of ecu tuning who told me what is going on.
It was funny when i confronted him on topic of his location and other things lol.

His story:


After confrontation:



Was strange to me at the time why someone from Ukraine takes payments in CAD but after I have discovered why lol.

This is when he got angry when one youtuber whcompare his flash vs flash from reflash club. They are also Ukrainian but he calls them russian scumbags ... His flash didnt "win" it that video and was exposed for its shortcomings.

In reality some guy from russia did develop reflash for cl9 in late 2013. Local serge bo dealer - Full name Serge Bogdan - was braging to me how Serge stole that flash from Russians. But other people who were closer to Serge told me that he bought it from that russian and later has bough maps from other tuners for full line of honda cars so he could sell flashes.







He goes by "little bo" "serge bo" , "raccoon" on forums and has raccoon picture on profile, dont know is he is here. He is easy to spot as when confronted he will tell you that he is certified ecu tuner by honda and bigest names in industry and that he makes best header money can buy , that he designed and developed ecu software for tuning honda ecu that is same or better than hondata ect... all that without any proof of "his" work.

Also later I have found test from Malkom666 , in his test found that k24 likes to knock at 5000ish rpm with stock rbb intake therefore needs to have less igt at.that rpm range.

On serge flas it is 25,5 igt wot from 2000-7800rpm. + .95 lambda at that specific rev range is a baaad deal.



When I thikn about it I should have politely asked for refund instead of fking with him lol.

There is also one Croatian forum where he was laughing and calling names one guy who lost engine because of bad batch of fuel on his reflash but cant find it now for the life of me as it was back in 2015. Maybe it got deleted.

Long story short ... Some one develop that flesh for stock car and that is the end of story. Serge took advantage of situation and ignorant naive stupid people like my self who want tuned car for 250 euro and expect everything to work perfectly.

Found more pics of head side of intake manifold,
This manifold was sold as "tactical racing intake manifold" from Tactical Racing Honda shop in UK and I bought it from private seller used, who listed it as a S2 pro street.



Everything was finished in 80grit.

And Final vs stock print, was told that they can't put all 3 pulls 190+227+254 on same graf.

Went from 80hp/1l to 108hp/1l

Well, I have some data it is same dyno but different cars (ep3) with comparable mods only difference was one had RRC other had Fake S2 PS.

This is car with RRC 238hp



This is ep3 with fake S2 PS 233 and top looks bad. Red line is overlay of car with rrc


I don't know if both cars had 50 vtc.

Internal of real S2 PS


Fake S2 PS



Dividers and runner entry is very different. On fake one it is almost square edge on the bottom of runner entry.

When we tuned vtc on dyno, it was some junk dyno, calibration was way of but we went on with it only to use it for curve response...got it rented for 30eur/1h so can't complain. We tested from 21 to 32vtc at the top and 32 made the most hp. So that was a bit unusual.
It would be interesting to know why some setups make max power at 10 and some ar 30 vtc.

The cam phasing angle (= VTC angle in Honda language) tells how much scavenging overlap is available. If the exhaust pressure at overlap is higher then intake pressure, the engine don't like that angle advance. A retard of the VTC helps to get out of the pressure at exhaust as pressure are crank angle related, come and goes as pressure waves. A few degree later the underpressure is available where the engine sees more scavenging efficiency and thence better torque.

The top end power at low VTC, e.g. 10°, is only valid for stock setups, huge pressure resistance caused by stock exhaust system = bad for torque everywhere
The top end power at higher VTC, e.g. 40° is only valid for a few NA engines on bigger cams. But not because of the scavenging efficiency, because of the disadvantage of having a backflow at the intake valve. Cams are too big. If not retarding of the cam brings more power, and the cam is also in max. advance position, the camshaft is too big.

The orange torque line corresponds to 32° VTC? The yellow one to 21° VTC?

The pink one looks like it has a too low scavenging efficiency and a too late valve closing...bad compromise on both sides, we don't like .

Wanted to share my Dyno tune results since I' learned a lot from this thread and it initially swayed me to do the rsp swap after reading about it in another forum.

The engine is a factory sealed/untouched k24z3 auto in a us spec cw2 wagon.

Mods
modded stock intake box with upgraded panel filter and 4in tube from the bottom of the intake box leading into the wheel well and layed out to an open tsx v6 vented fog grille with a 6in velocity stack.

Plm down pipe (2.5in)

Full Tsudo 2.75in exhaust

Stock tsx throttle body (64.5mm manifold side)

Plm water bypass

1in throttlebody spacer meant for r40 manifold

Rsp intake manifold, Tb port, port matched to tsx throttle body, water port cut and shaved. Thermal valve deleted tapped and plugged as the k24z doesn't need it. Untouched runners and stacks.

Thermal intake manifold and tb gaskets

UR light weight pulley (oem size)

Tuned via flashpro on 91 pump gas temp was about 55 if I remember right.

I have no Dyno time with the r40 manifold but here are the results with the rsp and tune.
The wagons are rather heavy (3586 lbs) but I'm happy with the results even with the auto transmission.

Plm Downpipe/header for the single port r40 k24z3 head
Elevation is 2001 ft above sea level
The 45 is from a parts bin at work. I needed to extend the tubing since the rsp sits differently compared to the R40 plastic intake manifold and the stock arm came up short.
