what all are your fueling needs? what all are you doing to this engine and plan for down the road?

if its just a stocker for now a simple 190lph pump would more than suffice.

best bet is to keep the canister purge but its not necessary, its nice though

thermactor doesn't matter as its not important

Wow, I used to buy the cheap $30 ebay china made oem replacement hats, drill out a hole and put an AN fitting on it. /done

Only the 1999 to 2010 were returnless.

2011 the mustang went back to return style or as they call is 'mechanical' returnless which means the regulator is just mounted in the tank.

Nope the 1999 explorer does not have a fuel rail pressure sensor since it is a return setup as well but again henry just simply put the regulator in the tank. You could do the same if you want to just run one line up front. All you need is a PPRV for any 99+ mustang but you'll have to modify that line to fit it regardless.

marauder valve body already has the 'j-mod' from the factory

there's three things for the shift to occur on time

first make sure the vehicle speed isn't too high, thats in the shift schedule function fn23s if its the 2-3 shift, if the wot tprel speed value is too high then its going to wait until that vehicle speed to make the shift regardless. You can verify by the shift gear commanded at the bottom right of the dashboard.

if its not commanding the shift then its never going to shift

shift pressure is fn23dytx_vs - dynamic epc 2-3 shift
the last two columns should be wot shift pressure. If you kick those up you will command more line pressure during the shift. That could make it shift faster but it will reach a point where it will make it shift harder and not necessarily faster that's when you know you've got too much.

then you have the tcc fill last
fnup2dly is the 2-3 shift tcc fill time, kicked up that value will command the shift sooner.

Post your tune file and a log of this missed shift and i can probably see whats going on exactly from the log.

Attached stock bins

you have to go through the code and determine yourself if its code or something else

thats all up to you as the tuner and how involved you want to get with

but yeah you have to use the crai8 file since you cant edit the craia craib or any of the others.

thats all wrong

you dont emulate that change you have to write it key off

the xdf file isnt different, its crai8 as well

whats the purpose in writing over the file?

yeah its pretty common for ecus to get updated when a vehicle goes in for service

read the comments for each parameter and it will tell you what its for

You cant edit a craib file with crai8 its two different strategies, youll corrupt the file
also all you have to do is open the scp id scalar in tunerpro and it will show you the strategy / cal code tag

you need to download the yya2 file in the crai8 downloads, thats a stock 99 crown vic cal. yya2 is the police bin so theft is already disabled. 63.99 if max value (0xFF == null) which means your vid block wasnt setup on your ecu. Thats not uncommon.

the original bin file you read out can be deleted its absolutely useless since you dont need the pats code or vin from it.

I have a conversion script in the programming section of the forum to automatically convert file sizes for you.

that means you didnt diisable the kam clear patch correctly

what do you mean you didnt change much from what i had- disabled patch? disabled what patch?

spark is supposed to drop on closed throttle at higher rpms thats the objective

thats not backfires thats decel burble, it means you dont have enough delta pressure. You can simply kick up spark on decel to reduce it but in doing so it will tske longer for rpms to fall and youll have less torque reserve

nope, fueling has nothing to do with throttle position. Sounds like you need to dial in your fuel injectors.
