Welcome to the forum SQ.
I too have read a bunch of this thread. I just dont have the imagination it would take to try doing a tune on My own.
John over @quadstar87 can fix You right up with a custom tune.
That takes a LOT of understanding of how the systems all ties together, aaaand, what to and what not to mess with to get everything tuned the way a feller would like it to be.
I thought I would try doing some tuning. I have a 78 MG-B Roadster. Switched it over to the twin SU carb setup with a few mods to accept some fuel injectors.
Put together a DIY autotuned controller, installed a heated O2 sensor in the exhaust hooked it all up but I did not understand enough about what to and what not to be messing with I finally give up and put the EFI system on the shelf. I did make some changes to the control unit, I should see about getting back into the website and see if they have a stock program loaded and maybe be able to put it all back to the way the computer was when original.
That's My experiences with trying to do a tune. LOLOLOL
