S_AUJP Version 7 - Now Supports Turbo (August, 2021)

[1project2many]

Turbo Sunbird/SYTY, Turbo Grand Prix, and Lotus Carlton all have boost control code in P4 ecm's. TGP and Sunbird code is known for overboost and spiking. I've played with some of the parameters and it's possible to adjust the code for better response. But I ended up setting desired boost tables to max and using throttle to modulate HP. However, it might be worthwhile to include safety functions if ECM is detecting knock that can't be resolved by retarding timing. Could save a piston or two if you could increase fueling and decrease boost.

1Proj --
Agreed. Thanks for your suggestions. They along with others were considered during development, much like what was done in $12P with a staged shutdown if issues. But had to end somewhere to get this beast released. Took the approach that anyone who installs a Turbo and immediately goes WOT at 2 or 3 Bar is not sane. Easy does it and always on the rich side with low SA is the proper approach. If that's done, many issues are solved as we noticed during our extensive testing and logging.

Programming is somehow a task that never ends.

I was thinking more along the lines of the Sy/Ty and Code59 type boost control, which has worked well for me. The tables are there and allow for lots of adjustment.

And that is why youtube videos are so fun to watch.

Started planning a NON gm i4 to run S_AUJP. Would run 4 saturated injectors NA and use electric fans, manual transmission. I have downloaded and the docs. Just to be clear before I throw money at a project, would a 7749 work with an i4 memcal?
Would it need to be pinned as a 7730? What pinout would I use?

I seen the recommended settings for i4 but it says untested on i4, am I really in uncharted territory?

Would i be able to make use of the two injector drivers in the 7749, and run bank fire, or is it batch fire only with this code?

Any info is appreciated ��
Thanks
