DYNO Result Low - Help!

**Suntzu** · 17-10-2007 01:23 PM

I've decided to do a heap of mods to my engine which is stock at the moment. See Suntzu's Mod Log for details.

I therefore decided to get a baseline Dyno today before adding mods.

Heres the result:

86.5 KW WTF!
Its really low as you can see and the manager told me my car is running ULTRA RICH. He told me to get honda to have a look at it.
I warmed the car up with a 4 km drive and did it really softly so it might have been a bit cold but the engine temp was in the normal range.

I don't know what gear it was in. I do know that he forgot to put the VSA off initially then realised and then did the run. Two runs in fact.

One big issue I saw was that when i got the car back the engine check, VSA and every other warning light was on. I stop my car and turned it off, restarted and drove off and all the lights cleared. The car drives fine, its got plenty of power and feels good.

Im thinking that the engine management went nuts when the first run with VSA was on and that it didn't clear during the dyno run so the ecu ran it super rich as a fail safe? Any ideas?

How can I tell what gear was used?

I need some advice about sorting this so i can get a proper dyno run...

If I were you I'd get Honda to look at it first.
When I did my dyno run the VSA was on at first and had no effect on the final run (over 110kw for a 5AT stock). The warning lights also stayed on for 30seconds or so afterwards so that's normal.

If Honda say it's ok, go somewhere else for another run and make sure VSA is off from the start.

Thanks for that info Bill, at least I know that the engine check light is normal.

The thing I dont get is that the car feels like its got a heap of power and is very responsive and smooth to drive, as per normal. Its also not using any more fuel than usual.

Im worried honda will think im an idiot if I rock up waving a dyno sheet!

Would running the car in the wrong gear do this ? Its a manual.

hey buddy, i did my dyno there too, first run VSA on, second run VSA off... both within 1-2kw of each other, so it didnt really affect anything...

yeah my fuel ratio was around 12-12.5... so you are running pretty rich... 86kw!?!? thats not good at all... atleast it proves my car didnt run on a dyno with wacked figures

so my 130.9kw is awesome

lol

sorry to be basking in your bad fortune

if it makes you feel any better, my new boot came today, and the corners got f*#$en bent in transit!!!

what gear was it in when u got this reading? did u do the dyno in 3rd or 4th?

**Suntzu** · 17-10-2007 07:10 PM

Ive got no idea what gear. Might have been 4th or 3rd?? Will this have a big effect on the result? Im about 30kw down!

If those dyno figures are accurate then your car should feel EXTREMELY sluggish and slow. And since you are not feeling that, there's a good chance the dyno is not giving accurate readings. From what I've seen a stock manual Euro usually makes around 105kw atw on the Dyno Dynamics dyno. You're getting 86.5kw stock and EUR003act is getting 130.9kw with a few basic mods? Something's doesn't add up.

You know its only about 3-4km to the dyno place. I was showing some engine temp but not a lot. On top of that im running 98 ron. Car was dead cold when i left.

Im thinking my car was in warm-up mode?? Is this possible/feasible?

my 130.9 was a true and accurate reading
