  • SAFC tuning questions

    I understand that to properly tune a SAFC you need to install a WB O2 sensor and tune it on a dyno....no problem there. Here's my question.....the dyno shop here has a WB O2 sensor they can use temporarily to tune my car, so is there a need for me to buy a WB O2 sensor?

    they probably hook it up in your muffler.

    it's always good to have a wbo2

      I'm sure it is....what are the reasons that make it better to have it? What benefits are to be gained from it once the SAFC has been tuned to the car and are they enough to justify the cost of an WB O2? I am running a N/A saturn with the usual bolt-onsif that helps at all. I'm sorry if I seem dumb about this, but the truth is that I am. Tuning an engine electronically makes about as much sense to me as how a hydrogen power car works, so help an old guy along here...alot has changed since adjusting jets, timing, etc on my old 'Stang.

      Thanks!

        if you have a WBo2 in the car with a read-out gauge you will know almost instantly if something goes wrong with your car's electronics or the safc, causing the a/f ratio to lean out. this can save you from detonation in the engine and possibly breaking a piston.

          the settings will need to be adjusted when the weather changes, it has been 20-30* here for the past couple weeks until a few days ago. i took my car to the track the other day when it was 55-60 and the afr was 14.5 or so, before it was tuned to 13.1-13.3.

            Is this the best WB O2 sensor assy for the bucks?

            http://www.qksltwo.com/forsale.html

            Where is a good place to mount the gauge (96 SC2)? Can I tune with this without going to a dyno or should it still go to the dyno for tuning?

              from what i've seen and heard, Ian has good deals on his shizz

              you can do a rough street tune, but you'll get the best results from spending time on a dyno

                It's not as important for an N/A car, but if we had a working wideband in Elvis' car, he might still have a working engine.

                    its good to have your own to see when your tune changes, because it will.

                    just a change in humidity can do it.

                      Will this one work well on our cars? I am running the N/A with the usual bolt-ons and have a SAFC Neo to use with it.

                        why not just this? http://store.summitracing.com/partde...5&autoview=sku
                        Guage and controller built in one, with outputs to your neo. I don't see a reason for the twin channels and the extra hundred bucks

                          and from what you can see, this has already been suggested in this thread.

                          And at $39 less

                            Cause the one I listed is avqailable to me right now at $200...that's why. So back to my question....will it work ok or is it too much for my application?

                              if the dyno can tune your car with a wideband then there's no need to buy your own. it'd be like buying an evo and installing a boost guage: sure, there might be a time when it can help you diagnose your car but really there's no point in having that information.
                              ive never seen a car dyno tuned so i dont know how well theirs will work. if you dont have a cat then they can put it in the tailpipe and itll be accurate if maybe delayed at low rpm.
                              having a wideband in your dash is only for your own tuning needs and for emergency diagnosis, like a temp sensor or a low oil pressure light. if you get an safc2 or better then you could save the dyno shop's setting in one databank and set up a second one that you can play with, and then you could tune for changes in weather.
                              if you dont plan to ever tune the car yourself, and if the dyno can tune it well, dont worry about a wideband. my advice might be different if your engine was boosted-the wideband could help you save your engine in case something happens. but due to the saturn ecu, your engine wouldnt have a random problem that would kill it any more than a stock saturn...unless the shop sucks at tuning.
                              yeah, that aem you linked would be a good one.
