did you hook up a volt meter to the fuel pump, doesn't seem like its engaging
there are at least two in the repo, https://www.hptuners.com/my-account/tunerepository/?
is there a mismatch between the map and tip readings ?
suggest checking voltage from each with car on and not running .. i'd expect 1.65v not 2.08 (2.25bar)
just stumbled across this.. old post
thank you for the updated SEP 1500 xls.. i'm going to try it..
that part matches to a 5.7l 2018-19 challanger
googled
shows this stock tune & it should have the data...
appreciate the advice, will do the GM refresh.. i have a buddie.. that could use a case of PBR's
did GM ever offer stage tunes ?
would a write entire work?
not sure who's tune it is.. i'll send trifecta the VIN
customer wants to return to stock and the pcm has a locked tune, x7F.
if i use a stock tune from the repo, change the vin, and apply 2 credits .. it should work, right ?
could be out of pump too.. autozone loans a fuel pressure gauge .. tape the to you windshield and video a pull to see if it drops..
and post a log
its out of injector - 95% @6200rpm @ time stamp 5:19:15.130

source in listed in picture119335
hellcat's are the same
if you search around the theory is because most gas is 10 ethanol, hence 13.8
try increasing the dfco cutout time from .39s to 6.0s
why is the IAT "-84F" ?
(ambient and coolant are fine)
agreed, copy spark.... fuel pumps are different too.. probably worth adding e85
quick search shows a stock demon tune,...
i would drain and put in known good fuel (fresh from another supplier) better yet e85 (and measure it), new plugs (if you have white crust on a plug could be oil being burned in that cylinder) and...
at time 11:36:39 timing is pulled due to knock, crap gas ?115959
i followed this to graph the lt+st and modify as needed (usually VE if your injector data is good), https://www.youtube.com/watch?v=Rhg5NSh8Dq8
i pull the pcm fuse for 10s and that resets the LT...
which injectors ? x or x2?, base fuel 58psi?

I’m sure there are others, below are 2 good tuners

I’d guess your out of fuel injector, 80# idle well and a 450 should provide enough fuel
Check on Facebook there are a bunch of good tuners, Dave Mario etc, that can help you
post a log with injector pulse width & TPS
what injectors and pump?
Contact agp they’provide a spread sheet of the tables that need to be modified
If this is a neon pm me and I can help you sort it out
updated
here is how i think it works..
ecm knows engine volume & VE & RPM & density... grams of air, knows requested AFR so it can calculate grams of fuel needed
actual injector pulse width is...
