srt8 300c no enrichment

[nooodles]

I have a 2013 srt8 with an eldebrock blower and comp cam here for a tune. I can make the car start and drive under light to medium loads but cant get any sort of enrichment under boost ie afr 14.7.. I feel like I'm missing something really obvious I previously tuned the car without the blower or the cam and it made excellent gains and had a nice fuel curve 12.8 afr. Its really starting to do my head in!!!

can anyone with more Chrysler experience please have a look?

have you changed the map sensor and rescaled everything for boost??
I see standard values everywhere...

Agreed.

fixed well sort of.. You guys were right it had a 2 bar map however our supplier told me it was a one bar!!. changed the resolution now we have fuelling. I have a few little idle and cold start issues but other than that it made 410 rwkw. I do have a question though, under boost the spark map seems to run off minimum allowed. is this normal or is there a way to overcome this??

thanks for your help so far

depends on how your scanner setup to check what kind of spark retard are you seeing

In the OP's original tune had WOT pedal threshold (controls when PE kicks via throttle position) was set to stock. The Edelbrock tunes I have seen always had WOT dropped just under 3V...where stock is closer to 3.5V. If PE tables are set appropriately there should be no impact to emissions...in fact at WOT the PCM ignores the O2s.
