2 bar tune for Turbo LT1 F-body possible with '93 ECM? DA3

[hotrodf1]

i can dig into other stuff that uses map to see if adjustment is necessary

i'd like to say we can set baro to a static value for a boosted engine, assuming it isnt going cross country (or maybe even if it is)

Thank you, thank you , thank you SteveO and Xnke for thinking about / looking into this for me. Looks like there's a few items in there to get me in trouble!

So you could potentially set baro = 100 manually, but I'd still use the 2 bar MAP and set all the tables as such, where 55kpa = 100 in reality?


I don't have much to offer in the way of solutions, as I just don't understand the code and how it works. (but I can test it! ) Is there somewhere you would suggest that I could learn up on this?

if running fixed baro i think you'd set it to something like 50kpa (7F)

these are all motorola 68k instructions, look up a tutorial on 68k (aka 68000) assembly code online somewhere, there are lots of them

Ok I’ll check it out.

And the ecu currently reads 55.4 kpa as the baro reading. So if we set it to that my current tune and all would remain valid I think.
