        i have a rather large thread on the 60degreev6 forums, in the OBD1 tuning section.

        http://60degreev6.com/forum/showthread.php/48100-nAst1-Progress-and-Concepts-Thread

        currently 384 posts..... and i know a lot of them are from me, and i tend to get quite wordy, so you may want to set aside a LOT of time if you're going to read through all of it.

          Robert, I don't think I have the extra SRAM, I know my ECM is not modified in any way. I remember reading some details about your nAst1 calibration. Can you refresh my memory on where to read up on it? Thanks,
          David

                  David, if you're running a 16149396 or modded a 7730/7727 to have the extra SRAM in the 1800-1FFF range, you'll be able to basically copy/paste a lot of your current tune into a nAst1 BIN. it has quite a few features that normal A1 does not have.

                    Robert, I would love to see this. I have an $A1 turbocharged car now. I re-scaled it for 2-bar and it runs well, but yours sounds like a much better solution!
                    Thanks,
                    David

                            assuming nobody else has, i wouldn't mind sharing the patch i made for nAst1 to allow up to 3BAR support. you may have to do some digging to find where to apply the jump/return locations, but otherwise it's been bench-tested.

                            the way i have it setup now, it accounts for fuel via a 2d table with 10kPa increments to 300kPa as a BPW mulitplier. for spark, i just have a basic "retard vs kPa" table that runs from 100 to 300kPa.

                              Anyone played with the code for the PCM-6/7427/8625  etc... to allow 2 or 3 bar map for turbo application?
                               
                              I'm running the $0E with MPFI and the 4l80E but thinking of adding a turbo.
                              I've seen the WB code but haven't seen anyone mention turbo/supercharger addition.
                               
                              Thanks,
                              Bill USN-1
