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.

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 .

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.

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.

      Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though

      and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.

      Oh, you are right. But, in Australia E10 is based on 91RON fuel and ends up being 94RON. Hence it being the cheaper option for economy cars. The more performance oriented cars go for the 98RON fuel that has no ethanol mixed in. The only step up we have left then at some petrol stations is E85.

      There is a warning that "this thread is super old" but they ignore that anyway...

      With 10% Ethanol, we're talking 2-3% fuel consumption difference. The emissions reductions and octane boost in my opinion far outweigh this almost non existent loss.    My tanks sitting at 80%. Luckily that should go down fast as I'm on vacation again for the next two weeks.
