Making sense of dyno reading
|
Mon, 18 April 2005 20:56

I had the A'PEXi Power FC put in on the weekend by BEL and given a 'base-tune' (ie. not on a dyno). I took it to RUF and they suggested to give it a safety run first, so they put it on the rollers and made it run at speeds of 50, 70 and 90km/h. I got them to printout the results after it was finished.
Was wondering if someone could interpret the figures for me. A little hard to make sense of but I do know that the car runs better and boosts quicker, even though apparently the base maps are all over the shop.
Cheers.

Looks fine to me but I'm not a professional so why ask me?
Give them the car, let them have it for a few days and get the tune done.

Dude you're not the only one here... I'm asking for anyone's help. 
When I can afford it, I'll get it dynoed properly. It's running great now but my only concerns were the A/F ratio's.

And why do you have "Colin Camel" (of the RAV4 camel series of stuffed toys) as your avatar?

the 10.9 around 2500rpm is way too rich and only on very low boost there.
at 4000rpm on 8.5psi seems good though.

What would you prefer, to drive it around now for a while as is wondering, praying its gonna live?
Or to spend a couple of hundred $$ and get the thing dyno'd so you can comfortably hammer it when you shall so desire?
I know what I'd be doing...
As as for Colin, he's cool, I've had him for years.

Looks like a third gear series of runs at 2400, 3400 and 4300 rpm at varying levels of load.
At low load, seems to be a bit lean (AF 14s) but seeing as it is low load, probably safe. I'd be a little concerned at your middle 90 kph run (? midlevel load?) - it is quite lean (AF 14.4) yet you are on boost, albeit only 2.5 psi. What's going on at higher speeds and at differing levels of load?
I would have the engine tuned sooner rather than later. You have spent large sums of money here - spend the last few hundred and get it tuned right.

I wish it were just a couple of hundred bucks to do it, but it's $600 plus for a full tune (needs 4WD dyno here guys) and most of a working day to do. When I have the cash I'll get it tuned right. It's been going like crap since August last year with the standard ECU in there, and now it's better than it was thanks to the Power FC on board.

And how much have you spent so far on motor/turbo/rings/bearings/gaskets/seals/heads/cam s/etc/etc?

I always use Matt (the hitman) for tuning. Never charged more than $400 (usually cheaper) for a very comprehensive tune. Might be worth contacting him.

Not the point... point is that I don't have that kind of cash right now to throw at it.

Is it a 4WD dyno?

no and unlike the porsche RUF these guys have been notorious through word of mouth of destroying ppl's cars.

No, thats the WHOLE point.
If you have spent, lets say $5000 on building the motor, then whats another $400-$600?
If you don't have the money, the solution is simple, either borrow it, OR DON'T DRIVE THE CAR TILL YOU CAN AFFORD TO TUNE IT.
The LAST thing you want is to give the car a couple of quick squirts thinking that you will be safe, only to find out that it is running lean in a few spots and you have inadvertedly cooked a couple of piston/valves/ring/whathaveyou.
Think about it.

Not sure if Matt's dyno is 4wd or not. He has recently moved into new premises.
But he can do onroad tunes also which seem to make driveability better than the dyno tunes i've had. Of course cant safely do full boost tunes on the road, but can do majority of the maps.

Cruz, I asked for an opinion, not a lecture. Sure it's good advice and I'd take it if I had a little shitbox to drive around instead, cos be stuffed if I'm taking public transport to work and back. Right now that's what I use my car for. I've borrowed whatever I can against this car, and I'm struggling to pay that off.
I thought about it and the ECU I WAS using (standard Jap-spec 3S-GTE, Blitz chipped) was more dangerous to this car than not having this Power FC tuned up right.

You're right. You asked for an opinion and you got mine.
If you want to drive an untuned hey, its your money.
I just know what I'd be doing given the same situation thats all.
Just trying to help.

Relax you two...
Getting your car tuned, is, very obviously, very important...
you know that, and Peewee knows that.
My advise is... Dont do any spirited driving until you get it tuned, at least this will minimise the chance of fucking your engine up.

Well that's what I had done with mine... according to the laptop, the ECU is "in-between" maps, but the drivability is great.  I don't usually go thrashing my car but it's good to give it the occasional squirt off the lights.
Is there a medium between the two? Good drivability and good tune?

A good tune will give you good driveability.
A quick full power tune will not.

Hmm from an onroad tune those figures looked pretty average?
Usually with Matt we do a dyno tune, then a quick on the road tune just to smooth out some of the settings.
Like Cruzsida said, a good tune will give good driveability also. Smooth & efficient when driving around, good idle and correct mixtures and timing when flogging the shit out of it.
There doesn't have to be a compromise. Thats what aftermarket ecus/intercepter things are for

Mate i told you this shit at Jamberoo!!!!  One more time and then you're on your own. Reset the Power FC to the original base map..takes 2 seconds to do and the base map is identical to the factory map. It'll run like a charm, but must use Optimax or similar not just the usual hi octane. Then, when you have the dosh get Matt (or whoever but Matt knows the Power FC well by all accounts) to tune it properly to get the last few hp from your exact setup.
I ran my 205 Power FC on the base map for ages and even ran up to 19psi no probs...still had a nice safe 11.5:1 A/F at that boost. The only reason Zasa now needs a retune is the dirty great Garrett hanging off it and the Blitz cams. I doubt yours would even need any tweeks as the mods are so mild but can't hurt if you want to go to that effort.
Right got that?
