The ultimate LT1 $$EE patch thread

the stock math and strategy on everything regarding barometric pressure in VE should do a really good job above sea level if you floor it occasionally while driving through the mountains, which any human being with a heart and soul is bound to do. i wouldn't touch any of that stuff.

where things have gone wonky for me with barometric updates is if you floor it, and your air intake is restricted in some way, that's your new (false) baro pressure. if you have a dirty air filter you could easily be out a few kpa from the key on engine off baro init. can't really calibrate for that, though.

Thanks for your input Steveo. I've felt that once I get the cells in the 20-45 kap logged with actual under load values and not just very light throttle to decal It will all come into line. As far as the ability to achieve the actual baro at elevation at key on hasn't been a issue, it either matches or is off by 1 digit less with this build. My concern has been the factored logic that recalculates the baro sensors seamless switch to that end of the range per say while climbing or descending into the atmosphere...lol

I'll shoot you a video of what I have going on with the induction.

Any news on nitrous patch ?

**WASyL** · 01-08-2023

still working on that nitrous thru EGR control. I don't know how gm/sec value is calculated so is it possible to do patch that does this:

table "26c2 MIN EGR DC% vs airflow" change load value form gm/sec to MAP reading

best regards

I apologize if this isn't the right thread to ask. I want to make sure I'm using the latest released version of EEHACK. I have seen reference to a V5, but the current download on ecmhack.com is 4.9.3.

Thanks!
