Std Injectors Over 240 Rwkw

[macka'sxr6t]

I believe that this thread is somewhat useless unless all of the cars are tested on one type/brand of dyno, same day/environmental conditions, and with the same fuel octane, there are huge variations in power measured across the different brands of dynos.

I believe that dyno numbers should only be used as a tuning tool to assist in a cars development. The dyno numbers combined with 1/4mile MPH will give a much more accurate indication of a cars true power.

What Peter says about different conditions is very true too. I remember one of the first dyno days at Dynomotive in Bayswater. There were a dozen or so auto T's 10 of them ran 1855-190rwkw's and mine and one other ran 201rwkw's. The only difference between the cars was that the 2 that ran 201rwkw's both used 98ron fuel whilst the rest used standard unleaded.

With my next comment I'm not trying to upset anyone. I find the 260rwkw's a bit hard to believe for edit only. An auto T with 260rwkw's should be able to run 12.8/12.9 @112mph. I hope they do and it would be great if a few of the edited cars got some times so we could get a better indication of the true value of the generic maps.

I know that a GT with the edit had a dyno sheet with 279ishRWKW's. This car managed a best of 13.8 on the night. It had all the protections removed and 500rpm extra. It ran quicker before it had the edit.

I'm not having a go at anyone or thing. I'm just making facts that I know available for everyone to have a look at and make their own judgements. HPF have the edit and at somestage will more than likely use my car to see what it can do. I'll make sure to keep everyone informed of my progress.

Geea.

I am trying to understand how auto T's with the edit can run 260rwkw without destroying the auto box. From numerous ones we have seen before the edit, the limitations of the auto box are approx 240-250rwkw then they either go bang or their life span is dramatically reduced to a matter of weeks/months.

My Auto is under renovations at the moment, will be ready in the morning, its life span shorterned by my useage, failure to change the oil (ford don't change it until 60,000k's) & fit a trans oil cooler to it. I don't believe the power was the drama, I feel as though my activities with 240fwkw would of killed it just as quick. Will be fitting cooler Friday morning

238 rwkw using the Xede with standard injectors. EMS I don't know at present. We will find out soon enough though I have just got some more.

Scotty,

What ever you do don't get Ford to change trans oil. I had them change mine at 20,000. Thought I was doing the right thing. Drove it in opperating perfectly. Drove out after service Far*ed. Now slips changing to 2-3, 3-4 and occassionally goes bang when changing into 4th. At 100 kmh tacho reads 3200 rpm in 4th gear speed slowing tacho still rising.

trumpy with all due respect looks like you did not get the point did you? I was trying to keep all the    out of here hence the banter box bit!

look like this one will end up that way now!

If you have a problem with the way I do things, PM me with your great words of advice. Until then, stop the pointless posts.

To answer your question Dynowog. I had a unichip in my ute for a few months with an APS Intercooler and a Malpassi Fuel Regulator running 10psi achieving 245.8rwkw. When I got the EMS I pulled the Fuel Reg out and kept the boost level the same and achieved 268.9rwkw. These figures are true and correct. 

<{POST_SNAPBACK}>

I might sound uneducated here, and in the world of tuning vehicles I am for sure, but it seems strange indeed that people claim all sorts of variances with different piggybacks etc. Some get 270rwkw@10psi, others it takes 12Psi. Some are running 350rwkw @ 13PSI while it takes others over 18PSI to make the same power.

Now correct me if im wrong, but dont these devices all do similar things?

If so then the variations are down to discrepancies between the realistic figures that their dynos provide.

From what Ive seen you need about 10-13PSI peak to make 270rwkw, 15PSI peak to make 310rwkw(both auto) yet we have figures all over the shop from everyone and their dog.

Suggesting that you can remove one chip and replace it with another and gain 25rwkw seems very odd to me indeed. Surely its the tune rather than the ECU and even then its still vague to compare. Perhaps tuner A spent much less time than tuner B. Who knows.

<{POST_SNAPBACK}>

I know what your saying Steve. Tuner A did tune the unichip to its full potential. From what I know that the EMS has more tuning capabilities than the unichip. Whether that's a 100% true or not, I am not sure. Maybe DW can share some light on this. With the unichip it was a matter of a couple of minutes removing it. Where as the EMS it is hard wired to your wiring system. Hence the hard removal of the unit. I have a cousin who has the TSI unit and we put his car on the dyno and he made 274rwkw with only 10psi. But he has a custom intercooler and a 4inch exhaust system. Since then he has done the plenum chamber and injectors with 11psi and making 306rwkw. Eventually he is going to raise the boost to 15psi but wants his gearbox rebuilt first.

I know you hear a lot of things on this site Steve but I tell the truth how it is. The problem I have now is Tuner B has been a friend of mine for 15years and Tuner A has is a friend as well. I dont like to offend any of them as they are both great blokes and have helped me out extraordinarly.

[Geeseman]

Thanks Joe. Im not having a stab or anything, it just strikes me very funny that people make 306rwkw with 11psi when others need 18 to get to 330.

There is something very wrong here. Either its the build quality of these cars is so different that its not funny or these ECUs have major advantages compared to the next or there are dyno discrepancies.

I dont know what the answer is but Id sure as hell like to be running 306rwkw@ 11psi, now if someone can tell me how to do it Id be most thankful

How about

EMS, 305 @ 10 psi. Auto

Easy try a differnt chip.

or he can go aps's best power for there tests to prove me wrong

peters words:

Guys, I've had enough of this back and forward posting this is what we measured yesterday on our dyno dynamics dyno in shoot 6 mode, the test car was an xr6t manual ute with an APS exhaust system, cold air inlet, and Unichip computer, very basic and common mods for an XR6T.

RPM RWKW's Inj Duty Cycle A/F ratio Boost PSI

4500 192 85% 13.6:1 10.5

As you can clearly see the air fuel ratio is very lean and is already running 85% duty cycle at 4500 RPM.

We nearly aborted the rest of the dyno run because of the dangerously lean air fuel ratio though wanted to show you how lean these air fuel ratio figures are by 4500 rpm, and by 5000 RPM the air fuel ratio is beyond being ridiculous.

Now I'm sure it's possible for another engineering test to show marginally different air fuel ratio, power, inj duty cycle, and boost pressure though not to any significant extent.

Peter

is this all the power you can acheive?

cant get any more hey hmmm?

look at capa's site guys under the edit section and there is a dd dynosheet to prove 254 rwkw is the dyno capa used wrong?

look at the runs from herrods 251 rwkw on a dd dyno is this dyno wrong?

or is crazy f6 's car a fudged dyno run look at your site and then ask him weather or not pretzels did the same numbers +4kw

if my dyno is wrong peter then you not only lied to hilly but to the world by posting it on your web site!

so peter if you are not up to the same level as your competiters shape up or get out of the game!!!

I'm not the only one acheiving more than you!

rigoli's did

capa did

herrods did

and im sure as positive nizpro can!

peter and suporters yes dyno dynamics dyno's can be fudged easily but you cant fudge a mainline dynolog , dyno logic and almost a dts!

stop talking peter!
