My Ride: 330ci coupe
Since I have RS4 maf i wanna try to work with it see whats gonna be better draw or blow through setup and from there ill try to tune it myself so i could drive to a shop that will tune it for probably ( or maybe i wont touch it at all and just drive to the shop with charge pipe off and maf on stock position and swap it at the shop. Anyways I cant say anything for sure yet , i gotta get the turbo at least so I could start matching up, because 1 of the engines i got in the backyard , the subframe is still on it or engine is on the subframe with motor mounts etc, because 1 of the cars my dad had in the backyard was a coupe 330ci with 20k miles on it , and some retard with fireworks set the car on fire , so we saved all the subframe tranny engine , but body couldnt be rebuild cuz fire department cut the roof off to put the fire down , kinda said that 20k mile car gone but that was years ago , and its time for the remaining of the car help me. Once everything arrives I will bolt up manifold with a turbo to the engine and I will start making a custom mount ( P.S im **** welder so im just gonna tack it together and let someone else weld it ) hopefully im smart enough to figure this out)

In another forum there is one with a stock M54B30 with ~600whp record for M54B25 is ~800whp if i remember correctly.

Plenty of space. RS4 maf curve should be dailed in?! JD Improved should be using it?!

If i would of turbo charged 2.5 , I can get pistons dirt cheap that are the same as CP quility wise not sure what the CR will be , but for 8 pistions you would pay 100 bucks or less ( pistons come in sets of 4 )

So 10 psi it is ?

As long as there is no physically limitation, i would always go with the stock parts first!

It is explained in the wiki , I already made a map for bigger injectors
VERY EASY , but i see guys talking about latency and I tried to look it up but cant find anything ( hopefully latency on my injectors are close or the same cuz they are siemens deka also just 440cc ( also got 458 cc which are the green ones )

Deadtimes is this i think "ip_ti_add_dly__vb" ..You can get away with stock latency on such small injectors.


Anyway in the WIKI i se ALOT of Maps and constants but which of those are the Global constant for injectors? I get that the fuelmaps must be tuned but im just interested in tje injectors. Scaling injectors is a very important ting to do and calibrate before any tuning takes place..

I found these.. Seems to be constants for each individual injector
T_ti_as_0
T_ti_as_1
T_ti_as_2
T_ti_as_3
T_ti_as_4
T_ti_as_5

And these. some of them are pure Fuel maps in my view.. They should all not go under topic injector scaling? Wich of below is just for injectors? Wich did you edit?

c_ti_min_iv
ip_ti_fl__n
ip_ti_cst__n__tco
ip_ti_fast_wf_thd_min__tco

I edited all the maps that are given in the wiki except latency , the way It is described there.
But i havent tested my tune yet , because Im waiting for the fuel injectors O-rngs and filters
Well my injectors sort of close to stock so I believe I dont need calibration , but telling you once I get the O-rings Ill swap injectors and see how the car runs and from there ill see what I can do.

Ok.. Many of those mentioned above i cant even find in the XDF provided.. hmm
Ill do some reserach and get back with some info on this.. I will test this on a 630cc E85 car soon so we will find out a more exact way on how to do this correct

Ive started giving the maps some more usefull name before we created the wiki. So right now some maps are more difficult to find due to me being lazy
