my dyno result very strange

[Guest lixid]

hey guys

i got my power fc fitted and dyno tuned tonight

198.9rwkw

it's not bad right??

i feel the car run more smoothly, and speed goes up pretty quick.

but the thing is before power fc in, it is 197rwkw already, is there somthing wrong?? i don't know.......

tonight from 6:00 to 8:30 two and half hour job.

at first i was happy but when i see the graphic i found that there were not much gain.

at the mid range from about 4000 to 5500 there are about 10kw gain, but at the top it is almost the same. but at end the power stays the same for another 500rmp or so over the stock range

at the right bottom of the result, it says

" Gear 3 Tue, Jul 16, 2002 08:07

Gear 3 Tue, Jul 16, 2002 08:01

Gear 3 Tue, Jul 16, 2002 06:37 "

i think those are the times they did the dyno.

power at engine is 234.1 kw and at wheel 198.9kw

and also, my avc-r act funny too. the low boost is .85 bar, but it go up to 1.01 bar.

please give me some advice on it and i will go to talk to my mach. tomorrow when i go to pay him.

what the hell

there has to be more than just the computer done

ONARUN's car has computer, fuel pump. fmic, boost, and a heap of other **** and its only got 180rwkw from memory!

[Guest lixid]

that's why i think it has problem

[blind_elk]

It had a run on the dyno immediately before they fitted up the PFC?

Better midrange has to be more useful than topend. Hows the air/fuel on the 'after' run? I've seen them tuned to around 12.5 .

[Guest lixid]

my power fc was fitted a day before the dyno, so when i get there they swapped it back to factory ecu and ran the first dyno and fitted power fc for the second.

what air/fuel should it be ?

i will go to ask my mach today

[BOOSTMEISTER]

I have seen this a lot lately....It seems that the PFC tends to smooth out the standard curve and not actually give much overall increase.....The HPI R34 GTst only got 7rwkw extra with the PFC installed.

[Jay95R33]

What boost levels were you running with the standard computer, and what boost was your running with the PFC?

Were they the same?

Just a stab in the dark but maybe your running less boost with the PFC?

[Guest lixid]

same boost all the time, .85bar

but as i mentioned before, it went up to 1.01 bar itself. so.... i have no idea what was going on.....

[Guest lixid]

i read the article from HPI the R34 project. it seem my one is pretty similar to it except the turbo upgrade

[turbomad]

Before the PFC you had 197rwkw with no ECU mods at all, how?

My R33 has the same mods as yours and made 148rwkw @ 10psi with the A/F ratio mainly in the high 10:1's, with the ability to tune the air and timing that the PFC gives you, then yes I believe 198rwkw is possible, although some people on this site would have you believe otherwise, however before the tune I can't see how you made 197kw.

[Jay95R33]

The only thing I can think of is maybe your Stock ECU wasn't really stock.

It might have had a retuned chip in it.

Either that or they got the first (pre PFC) dyno run wrong.

The big question is "does it feel faster???"

[Guest lixid]

i have to say i don't feel it is fast, but last night, when i finish the dyno, and all the way back home. i looked at my avc-r which show i did over 180km/h. if you know want i mean.

it is so smooth, i don't even feel it is fast. but it actually fast.(i notice the mid range improvement for sure)

and today i went to see my mach. and he did a little bit adjustment to my avc-r(as i mentioned that it acted funny), it launched pretty hard(i mean fast), and got wheel spin at about 4500rpm at first gear, and same as second gear as well. with the same way i usually drive. it obviuesly got power increased.(after i set a little bit less boost at first and second gear, it goes awsome)

i am happy with what i got.

198.9kw sound not real, but it doesn't really matter to me now. as long as i know that the car is run well and safely.

197 rwkw from the ECU !! nice, do you want to sell the "Stock" ECU, I would love to try it in mine.

I'm making 144 rwkw at the moment at 13 psi (same sort boost as yours I think).

Mine is an R33 on a 93 with 70K on the clock.

Let us know what you think....

don't expect too much from your PFC, lixid, and its depend on the dyno as well.

mine nearly the same, except i got a bleed valve and a unichip.

with exhaust, FMIC, boost@12psi, filter. mine's about 163rwkw from around 130rwkw.

my unichip just tied it all together, lean out the mixture at 11.8 A/F add extra 10rwkw at 173rwkw.

lots smoother and more faster esp. taking off at idle.

[Guest lixid]

open the factory ECU up

and can't see anything special

[Guest lixid]

have a look

[Guest lixid]

dyno

[Jay95R33]

Hmmm, that ECU doesn't look like it's been modified... :confused: :confused:

[Guest lixid]

:confused:

[GODZILLA]

just curious is that dynoed in third gear if so why isnt it supposed to be on 1 to 1 ratio eg 4th that could be why its a bit high
