it sounds like the converter is staying locked during the shift making it bang

force the converter to stay unlocked and see if thats it

cant dial in the ve table if its in OL, u can enable it if youd like you should be all dialed in

wot pull is fine but not necessary as its in power enrichment now.

No good, you eased in to the throttle and didn't finally go wot til 2400 rpm.
If you force static stall sw epc you can't adjust for the shift.
min clip isn't the problem if its banging sometimes and not others

I think your overthinking this. Give this a go and LMK.

Again I have no idea about any of that as I hadnt used it in over 10 years and only recommend TunerPro.

I posted a moates QH thread the other day. Ive managed to get my hands on a ton of them so there will never be a QH shortage and the price is locked at $350 now.

yep np

pprv is a regulator so all good

you simply plug in your injector data for which ever injectors your running for the pressure your running just as normal

yep still do

whichever rpm you normally run it out to so it can be dialed in

kihp isnt broken out, if it is then its prob the wrong address but in any case it needs to be verified

what is the actual ecu connrctor pin # your using for the fan?

its either your inlet or your exhaust but something is restricting the engine from breathing atmospheric pressure. Could even be the throttle stop not opening all the way.

You need a 4.56 rear end. That gearing is doing you no favors at all.

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.

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.

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.
