      After a long hiatus from Kinja Oppo, I found this group. Thanks to those who reached out. I found Oppo again and I'm back! Still here, still fixing cars and stuff, still driving to work every day, no trips to the dragstrip this year though.

      How have you all been doing?

                Good to see you! I'm doing alright, all things considered. Nothing much interesting in the fleet, other than some fun with my scooters.

                                @whoistheleader I fix all kinds of cars. My brother and I have our own tire machines and I weld, we do brakes and tires for all kinds of people, friends and neighbors, etc. I'm always working on something. I have a '73 Buick LeSabre that's all our own handiwork and a '54 MG that's all my dad's handiwork, both of those need TLC but are overall pretty reliable.

                                The '73 LeSabre likes to frequent the dragstrip, but is also my tow rig (it has a class 3 hitch and can out-pull most any gas engine) for my car trailer. The Buick has a 455 V8 and we custom built a fuel injection system for it way before it was a popular thing to do. My grandparents bought the Buick new, and my parents bought that '54 MG in 1968, before I was born, so both have been in my family for decades...

                                  @deekster_caddy You should do a re-introduction post here as I'd like to learn more about those. Fuel injecting an engine that's originally carbureted. That's got to be difficult.

                                    @urambo-tauro dammit I killed the party again. no wonder the old oppo died. I'm here to kill it again! I mean. No.

                                    Thanks! Good to see so many familiar names here!!!

                                      @whoistheleader This is kind of my re-introduction post, no? Yes, it was difficult. At the time (around '99/'00) nobody had fuel injected one of these engines. We had an intake manifold plumbed for our injectors, then started tuning. This was before MAF sensors were much of a thing, so the fueling is all based on MAP (vacuum) and throttle position. We started with a generic "chevy 350" fuel and timing table, put in our O2 sensor, and tweaked settings until it ran good, started driving it and just kept adjusting things as we drove. Eventually we got the entire fuel and timing maps worked out and it's been running like a champ ever since.

                                        That's a really cool project. It needs "fuel injected" graphics along the side or something. Is that MAP stuff getting harder to actually keep running? It seems like people are moving away from vacuum systems for fully electronic ECU stuff in retrofits.

                                          @whoistheleader It's fully electronic, it just has fewer sensors. A MAF sensor measures precisely the amount of air entering the motor, which allows for precise fueling to match. What we are doing is similar, with a teeny bit less precision. Based on throttle position, RPM and Vacuum, you can calculate how much air is entering the motor just the same as what the MAF gives you, it's just a little harder to tune as you don't actually have an airflow value you could convert to CFM, you need to spend some time getting your other setpoints correct. If you have a vacuum leak it can throw your fueling to hell, but that can happen with a MAF too.

                                          The other thing that happens is that MAF-based tuning is restricted to the airflow limits of the MAF sensor. Many turbo/forced induction vehicles can exceed the flow of most MAF sensors, so custom MAF sensor mapping is required, or many tunes fall back to what we've always done, tuning by MAP and TPS.

                                          The LeSabre is one of those tanks that fits right in with the Millenium Falcon description "it may not look like much but she's got it where it counts". It's a malaise-era barge that can really move, and it looks to fit the part.

                                            @deekster_caddy Hey, welcome back!

                                            Things go as they go....new Oppo seems to be doing pretty well so far!

                                            Feel free to take a read of the rules (pretty similar to old Oppo in the broad 'don't be a dick' sense) here:

                                            https://opposite-lock.com/topic/1977/oppo-guidelines-and-user-guide-last-updated-dec-1st-2020

                                            The User Guide is there too, which you might want to read too as 'Hyphen' Oppo (here) is a bit different to old Kinja Oppo. Feel free to post any questions there if you need to!

                                            It's a work in progress here, but slowly but surely! 😄
