A few questions for those of you with Link ecu's

My gtr is about to get parked for the winter and I plan on installing a Link g4 plug in ecu and just had a few setup questions. 

1 I have a LC1 wideband O2 sensor that I will be putting in so do I even bother leaving the factory O2 sensors installed? I was planing on installing the wideband in the front pipe after the two pipes joint, does anyone run 2 widebands or just stick with the one?

2 I read that the Link ecu doesn't use the factory knock sensors, if so is it worth getting the Link ones and again just 1 or run 2 like factory?

3 What would be the minimum read level for a map sensor, I have a pair of gt2860r-5 going on and planing on running around 1.4-1.5bar and the absolute most. Any advantages of a 4bar sensor over lets say a 3bar sensor? I understand that sensors are rated in absolute atmospheric pressure and need to take that into account.

4  For boost control solenoid stick with a Link solenoid or is there other options?

Thanks

1. No need for narrow band O2 sensor

2. If you want to use knock control get a Link sensor - don't know of the advantage of two over 1.

3. 3 bar should do if you only plan to run 1.5 bar but your plans might change - if you can get a 4 bar for not much more why not.

4. Link solenoid is just a re-labelled Mac valve. ( I used a Mac valve).

Kind of old thread but I just wanted to chime in about the map sensors. They all output the same voltage range so while the 4 bar can be used for higher boost they will have less resolution than a 3 bar. I don't really know how much this effects real world tuning. But you should pick one for your future plans.

    • Motor done back together, surprised is a understatement with this rb30. just think 10m under flood waters for a couple weeks, 20lt water inside the engine for 3years. cleaning the cooling system installing new plugs leads and overflow bottle and then I’m closing the bonnet moving onto the restoration of the body.    already finished few external pieces for putting the puzzle back together. this has been very enjoyable, frustrating at times definitely. Moving forward with my silo sub!!! thank you to everyone that has helped me so far, ✌️ att.jiLuuIrdYfPMplUAOjVfrq4OOOc082zjTnt1kJrhKVQ.mp4
    • Oooh, right. That makes so much more sense. For some reason I was picturing them selling a variety of pipe ends with nipples on them... Solid reasoning.
    • 100% this, no point delivering a steam oven when the client just wanted a toaster 
    • The best part of my setup is, we only have two sites. Our head office where I'd put every thing has plenty of internet capacity. We're on a 200/200 dedicated fibre. Even better, there's only like 6 people in the office at most, and the other office has 2 people in it (likely 3 soon). The majority of our work is in a custom piece of software, as it is part of the backend of the system we provide to customers. For our arrangement, on prem would be wayyyyy easier, and a VPN tunnel site to site is easy for me to manage. Scaled at many many sites, or quite a few hundred employees it's starts getting a bit different for all people outside the head office. However, everything in the cloud becomes worse for the people who operated previously at the site that held the servers, as now they're at the mercy of their internet, and not GBPS internal network (f**k the idiots who hook a desktop PC up on WiFi or permanently sit at a desk using a laptop and don't go remotely with it).   It really does come down to the business needs and structure as to what is best. For us, 365 is mainly being moved to for office apps, moving email from Google to Exchange, and setting up "Active directory". Otherwise we have a ticketing system with support that runs on our own cloud system, or the sales process sits in a CRM we pay for. My biggest push back for having most of the shit turned off and saying no when people want new shiney things is "that won't meet our security requirements, or efficiency gains, so all you're requesting is money spend to open us up to security issues, or to make our staff less efficient" Which is funny when one of our core values is "To do more, with less"
    • Think of it as a fancy iFrame with the auth passed through to PowerBI as you're already authenticated logged into Teams   I'm the complete opposite, I hate everything on Prem, it's slow as shit, you need VPNs to get anything happening, then when you want on-prem DBs to talk to say PowerBI you need to install/setup data gateways to essentially VPN back into your SQL instance. I suppose from my perspective, on-prem sucks, but from an infrastructure perspective, your environment is somewhat air gapped to the web via your firewall(s), etc.   The curse of knowledge, the more you know the more you suffer. Farken philosophical shit.
