Last week I replaced the battery in my SVTF. It sat ‘battery-less’ for a cupla days, so the ECU reset itself to the default program. Previous to this, I had frequent issues with ‘lopy idle’, almost like I had a high-lift cam or something. When the RPM’s would drop to idle (~900RPM; like when I pushed in the clutch pedal), it would often fall down to near 500RPM, and sometimes stall. Since the reset, no more lopy idle! Cool beans.
Question: Does this mean that as the ECU program adjusts to my driving style, it does something to create the lopy idle? You’d like to think the car would run better – not worse – after the ECU has had a chance to adjust. Hmmm!?!

These cars do use adaptive learning, sometimes it's good sometimes not so much because it can pick up bad habits.
I always find that mine runs better after a reset although it made more of a difference when I had a stock tune.

Lets just say it's probably a good thing the adaptive learning can't remember to leave the left turn signal on for fifty miles at a time.oldoutboardjim wrote:Are insinuating that I have bad habits? I resemble that remark!

Seriously, if the '02 tune is as bad as the stock '04 tune, I would get 'the latest & greatest' tune loaded pronto. My (pre-JRSC) car was a royal PITA to drive (stumbles, couldn't go below 50mph in 6th), but after the updated tune, it ran beautifully.focinite wrote:ha dont know i think cus it has teh oe 2002 tune wit no updates .

His car is a regular ZX3 with an SVT powertrain swap, I think he'd have to pay to get the update and knowing Focinite he'll wait for the tune to fall from the sky before he pays for it.
Even Fords updated tunes sucked, all the issues with those tunes were cleared up with my tune from Unique though

My mileage may have dropped a bit but other than that it's a 99% improvement, starts better, doesn't stall, pulls hard.focinite wrote:what does it change . there is always give and take.
I still average mid 20s around town and get 27.5 with the cruise set at 83 or so.
You need to drive a tuned SVT before you say there's always give and take, Ford really did a poor job tuning these cars.

I, for one, will never know how good or bad my tune is. Because Ford chose to use this awful ECU system that requires you to buy a "tuning flash programmer", it would cost me $700-$1000 to tune my car (remember: my car has the JRSC+BBK). Am I willing to part with that kind of jack for a 2004 car? ¡No way, Jose!FORDSVTPARTS wrote:You need to drive a tuned SVT before you say there's always give and take, Ford really did a poor job tuning these cars.
And that's just the beginning of the challenges. If I was willing to spend the $$, there's no local tuner who will touch a supercharged SVTF with a ten foot pole!
Tuning-wise, this ain't no Honda or Subaru!!!!

I believe most modern cars use flash tuning, There's simply no way to properly tune a forced induction car without it being on a dyno or using data logging.
Almost no one uses a "chip" anymore, remember the old saying Jim, You have to pay to play.
