No, returnless will not work on the fox ecu as it does not have a pwm output available to control fuel pump duty cycle same as the explorer and 2011+ fords.
However 'mechanical returnless' is fords definition for having a short return line. Mechanical returnless uses the same fuel pump code as the return system since its only difference is a short return line. The fuel pump code for the 2011 fords and the 97-01 explorer ford copied from the 83-95 eec-iv.

Re: 1993 F150 4x4 - Trans Tooning
Log is no good you didn't go wot til 3700 rpm and 31.5 mph.
You need to go wot at 600 rpm and 0 mph to lug it down.
You have a major exhaust restriction, You were only at .92 mappa at the most at wot with a 26 map.
It shows you were doing 52mph in 1st before it shifts. Is that accurate?
if your reusing the knock sensor wire for your fan you need to disable the knock sensor in the tune. I'll add it when I get a chance.
Definitely need a wot pull from idle to shift rpm.

Re: Returnless fuel lines with an A9L
no need to quote the post directly above yours it just clutters up the thread
Yes, that's the factory return rail for the explorer you posted. Remember the regulator is inside the fuel tank so theres only 1 line from the regulator up to the rail same as 2011+ vehicles.
PPRV is the positive pressure relief valve, its the secondary regulator used on returnless vehicles 99-10. Ford used the pprv on 2011+ vehicles but since they are return style they call is a regulator.
I've always either mounted the regulator in the tank or next to it and kept the return line as short as possible. Its detailed in the pre tune write up on the homepage.

Re: 1993 F150 4x4 - Trans Tooning
No, its not in the write up fn074 is dialed in to get mapope where its reasonable. I prefer to dial it in so mapope has more resolution so you have finer control. A speed density write up is on my to do list.
She looked excellent. This should make her pretty much dialed in other than wot. Go ahead and shoot back one quick wot pull in 1st so we can dial in the top of the ve table.
LMK if the converter locks up now back to normal.
which connector pin # are you using?

Re: 1993 F150 4x4 - Trans Tooning
You had fn825a the ect dsdrpm adder locking out base idle control by adding idle rpm even at operating temp.
fn820b was multiplying the iscdc based on load. Not ideal at all when you can dial it in properly.-I see your using pin 21 the iac for your fan code?
I take it you don't have an iac ?
why is your spark so retarded down low? It looks to be over-advanced at high map low rpm as well.
why did you tack the fan code on to the logging patch?
You have wot kams referencing another cell leaning out wot.
Your mapope isn't dialed in which means your ve table is skewed. You also have 10 lbs set to 0 in' reference in the fn074a mapope airmass function which isn't right.
It looks like your injector offset is too low which is causing your crank PW to be excessive as well as skewing the VE table making it non linear.
This is the best I could come up with. She probably won't be too happy til she drops in to closed loop. She's forced in to closed loop at wot so don't do any towing or wot pulls.

Re: 400hp 351w startup tune
if pullin is exceeded it will
make a new thread for your truck with vehicle details and post your tune, ill take a gander and see if we can get it figured

No you definitely can't change the trans strategy while driving

Re: Returnless fuel lines with an A9L
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

Re: Returnless fuel lines with an A9L
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.
