Looks awesome! Freddo the frog strikes again! Good work fella
Just need a Green cotton filter instead of a Jetex now lol
Cactus green 8L S3 - B5 TIP + Jetex, Revised 007p, R32 rear ARB, AP Coilovers, Compbrake rear arms, Full Powerflexed dogbone.
To change the subject slightly, I have ordered some Bosch 550cc injectors.
I have been told by 2 sources that I should be ok to fit these and run them with my current map (temporarily till I get a custom map) as my wideband car should be able to dial out the extra fuel. I thought that this would be a safer option to go back to the 3 bar FPR, 550cc injectors, and have more fuel then to be running my standard injectors to the limit on a 4 bar FPR.
That said, what you are also doing is future proofing the engine. If you buy them now and have them set up with a custom map at A N Other time, then there is always room for more should it be needed.
Also, 3 BAR is a better option for fuel pump longevity.
All points win.
Ok, a few sums.
The standard injectors are 380cc @ 3 bar pressure. I am currently running them @ 4 bar of pressure (apparently adding 15%) making them 437cc.
Now, I assume that the ECU will throw up an EML if the fuel adaption is more then 25% on 380cc injectors @ 3 bar??? I'm not sure if I can work this out by the injector capacity or not but 25% of 380 is 95 and the 550cc injectors are 170cc bigger then standard so I'm guessing that I'm going to trigger a light?
25% of 550 = 137.5
550 - 137.5 = 412.5cc which would be less then the current 437cc I'm running
I'm not sure any of this is even making sense lol.
Here is the Welly solution to this problem.
Fit them, drive it, log for long term adjustment fuel trims.
See what happens.
If you're hitting - 20% IIRC thats removing 20% of the fuel you have already with the 4 BAR, which sounds about right. The injectors are flowing more for the same pulse duration than the ECU expects -hence the adaptation.
However if it's already at -20% then it can't have been that far off on stock injectors.
001 will give live lambda adjustment... block 032 will show long term and short term trims...
I suspect 550's on a 380cc map is probably going to end up outside the adaption limits.
Too much fuel can be just as bad as not enough.
That said, it shouldnt take much at all to adjust your existing map to accommodate the larger injectors, one value in a single table would sort it as a quick fix that'd take about 5 minutes to do.
Dialling in KRKTE isn't always as easy as it suggests... there is also TVUB to do and a few other tables to dial in to get fuelling spot on...
Cheers for the input guys. It's always nice to test these kind of things if possible and get info on it.
On a different note, I've just received an email from my contact at AEM in the US and he's goin to replace my WMI nozzle again
Why cant the revo map have its KRKTE adjusted? Have they fcked with the code that much that the tables arent in the same places any more?!
by my maths, the 550's will only need to be adapted 13.6% to be within that 25% limit of the 380 map.
