if we were in the business of removing chips and reflashing them with EEPROM flashers we could support the EGS52/53 no problem there is a reason why nobody supports OBD2 flashing of this TCM but i assume you already know that.
I'm just nailing down some final issues with my 300C supercharger install and once that's done beta will begin. I want to make sure we have everything required for NA and FI tuning.
I know it's frustrating, but the majority of our problems getting 2.24 released over the last 3 months have been 3rd party software vendor bugs breaking our development environment.

Just a quick question on the side that you mentioned FI. Do you think there will be custom boost OS's for the HEMI's?

I would say the only real need would be increasing the VE table size or adding a supplemental boost table to allow you to keep better resolution in the part throttle areas for calibrations running over 2 bar. The normalizers are great, but you are still limited in resolution by the table size. Other than that little detail, the NGC's are very boost friendly.

Yeah I don't see a custom os for that happening...for GM's we did them out of necessity since the pcm has a hardcoded maf limit and the normalizers aren't adjustable.
From the looks of it the NGC3 VE table is 17x17 meaning for 210 kpa you are getting increments of 12-13kpa which in our LS1 gm custom os's we get 10kpa increments in 1/2 of the years so its pretty similar.

It doesn't have to be perfect, it just needs to be done in two weeks...
A wise man once said "google it"
Ah ok that's cool. I'm looking forward to being able to look at the files and learn more about them. Thanks for the reply

also the axis values don't have to be linear, you can still get good part throttle resolution and then sacrifice resolution on boost, you rarely need much resolution between 100 kpa and full boost anyway

I just got to looking around on that and I'm pretty excited to start playing around with the normalizer values on a customer's turbo truck.

Chris, have you had success getting your car into OL power enrichment, without invoking wot through lowering the wot pedel threshold constant? This is enough of a problem in the Hemi community that some people are resorting to using piggyback O2 sensor signal conditioners to help bias the fuel trims so there can be some enrichment under part throttle boost situations . Either that, or run closed loop at stoich under boost
My maggie for my jeep arrives on monday with some hypertech programer crap with it, please hurry.
Sure, most late model engines will run at closed loop under high load conditions for a while, but there is logic in the controller that will at some point richen the mixture based on temperature limits of the exhaust, catalyst, and other components. Manufactures carefully test engine packages to know what these limits are, and run at these limits to reduce emissions and maximize fuel economy.Certain VW/Audi cars I've worked on use physical egts to measure and adjust fueling rather than calculating the temps . When you install a turbo or supercharger on a car that was never calibrated for forced induction in the first place, the temperature models that were set up by the manufacture are no longer accurate, and likely will not take into account the additional heat load. If there was an effective way to calibrate the exhaust/catalyst enrichment tables for us in the aftermarket, then I suppose that could be a reasonable solution to get power enrichment without going to wot. I don't except the idea that just because we see factory cars running closed loop under certain high load situations, for limited amounts of time, that it's ok for us to run closed loop boost.

Is it possible to tune NGC3 computers with HP tuners if you want to use the beta software?
