I am new to the LINK Community.
In simple terms, I just bought my wrx4+ and I will be looking to map it myself as I did before with my old ecu.
I am looking to see if anyone could perhaps share some info in regards with my first off setup, because the old ecu, was brilliant in the fact it was simple to use, few tables etc. I knew what i wanted to do and where that simple table is to be found, where the PC LINK can get a bit overwhelming, specially as I get sidetracked all the time by see all the nittygritty stuff (good stuff tho) .
So I guess, first question is if there's a topic / video going trough PC Link main features? [I been watching HPA's videos for most of the stuff already, however I'm wondering if there is like a basic one on software only, and how to find what you looking for in there, as I found the software with all these features can get complicated very fast]. Hard to explain myself here I guess, but in a way I'm looking for like the newcomers' guide to Link lol.
Secondly, looking at my spec:
MDX321T turbo coupled with the Newage STI 565cc subaru (830cc@3bar) decapped injectors , I am interested if anyone has some standard data for setting the injector dead times or some basic settings I could start them off from.. On my old ecu I didn't have access to this data, and it was just a scaler, which meant that during the initial part of an acceleration run I was getting a huge spike of rich fuel, and I would like to avoid this for the new setup.
3.I was also running 4bar of fuel rail pressure, relative to manifold, this was giving me very steady idle, however I'm guessing that if I can better control the injectors, I should be able to lower the fuel rail pressure, or shall I keep it as the injector spray pattern should be better at this high pressure anyways ? Obviously this pressure will affect my dead times too, this is why is confusing to me. The fuel system itself can take it, as is fully built up using new piping, parallel fuel fed to injectors all coupled with AN fittings.
4. ECU Knock = WRX4+ has this built in, however when I browsed the base map, I didn't see it enabled. Should I enable it with the OEM knock sensor ? If yes again, anyone could share what they use for the knock settings? Secondly, shall/can I buy a wideband knock sensor and set that up on it instead?
5. Looking at fuel/ignition tables not sure if because I was browsing the base-map without being connected to ECU but it seems to me that the manifold pressure used is an absolute value? Is that true ? if yes, any reason why not to change it to what i'm used to (as in relative to atmospheric pressure).
That's about it I guess, ecu's still not in car (pending delivery). the link can lambda is also going to go in, however I'm expecting that to come with instructions and presets.
Full spec, just in case you have questions is
version 4 sti heads,
Lateral MDX321T turbo
gt spec headers and 3"full exhaust.
and about that, rest is all standard supporting mods, like front mount, 3 port etc.
On my old map i made it to 409 but, but i didn't push hard or anything, as it was the first time i mapped it, and goal was just to take it to 400, plenty more to come from the setup with this new ecu now in hand.
Thanks and sorry for the long post.
