Damn, another VT user making TOO much power. We really need to do something about this problem

I know *shakes head* should have kept my hypertech
Did a wot run in 4th, about 3.5k the tyres broke loose and started spinning, about that time I started cackling insanely with the biggest grin ony face.

Steve you and your VT rise our tyre costs too much
I spin on 5th or 6th! Maybe should not mention that it's because of snow and ice we just got. May have to stop tuning for some months

Skiptownmcat, any Virtual Dyno plots?

Not yet, still perfecting a few things first
Tyres first for me though, then finishing touches and then I'll be off to a chassis dyno probably in the next week or two.

It would be most interesting to compare VD and chassis dyno results even if I don't know what it might prove. It's pretty straightforward to modify VT logs so that VD understands them (at least power & torque part). I have found that i must delete all decimals from RPM and add a field TPS=100 to every line, and change commas to dots, then it works. I can help with that if needed. Hopefully VD starts supporting VT soon, though.

Attach an edited file and I'll copy what you've done to make it work.

[manselainen]

Here's one. First I extracted (shared) a log from VT. It's a zip file, and I'll open .vtlog file from that zip with Excel. With my OS and Excel versions, it makes a table out of log (click yes, OK, OK). I'll filter out just PID 13 which is RPM. Then I'll search the pull and copy &paste Time & RPM cells of that pull onto another worksheet. There I'll add headers Time, RPM and TPS. TPS I'll set to 100 and change commas to dots. Then save into Text (tab delimited) format (click OK, yes) and voila'.

This way I get power and torque graphs. I have not succeeded in getting AFR or boost, there must be some syntax error there. But those we can see from VT so no problem.

VD is very sensitive to wheel spin so that must be omitted. It's accurate tool but only if raw data is accurate.

^thanks. I have a 6 and i got was less power than you.Im on 93 oct tune modified for cai/tip. Would switch to high load but in desperate need of intercooler here. My bat high 140degreee/59. Not sure how to use the software really, its nice to get a ball park number. Now i want to take some more logs and recheck!

when i used xml, everything was in dots already, the rpm pid was a cake to pick out then i saw where it said pid 13 and it all made sense.Just open a exported uncompressed log file with excel, and do in xml format.These may differ for you euro guys
pid 13=rpm
pid 29= actual afr
pid 19=map(kpa)


I got it to show boost and air fuel. I attached what i used. I think if you dont set it up in that order it doesnt work. took me forever to replicate it. You must use lambda and map as the headers


Looks like some nice flat power tho! Thanks to steve of course

[manselainen]

^thank you! Your power seems to be quite close and who knows if road is level, how's the wind, what's the real weight, tire spin etc. I tried the format you used and it works! VD tells it to be some stupid Hondata file but nevermind. Some more work in converting files but it's nice to have all the curves (log attached).

You seem to have some serious boost creep there, and shooting 1,3 bar at 6200 rpm Is it still stock turbo K04? It's way off from it's efficiency range there... I think you better do something about it before going WOT. Steve any comments?

Here are pid's I have run into so far:

1 Absolute load
2
3 Actual equivalence ratio (lambda)
4 Actual valve timing degrees
5
6
7
8 BAT
9 Desired equivalence ratio (lambda)
10
11
12
13 RPM
14
15 Fuel rail pressure kPa
16 IAT
17 KR degrees
18 LTFT %
19 MAP kPa
20 MAF g/s
21
22 Relative throttle position %
23 STFT %
24
25 Ignition timing advance degrees
26
27 Wastegate control solenoid duty cycle %
28
29 Actual AFR
30

its a tune steve worked on with me, the heat really made it worse. im running like 95 %wgdc, stock ko4 no downpipe. Its past its effiencieny range and blows a lot of hot air but im over that. still makes power haha. idk....another reason why i need to keep afr a little richer than ideal. i like power til redline
