Belive me not worth getting into in thread. It will turn into a shit show ans since both sides can not be on one forum to defend themselves, thats not something we should get into.

On FF it will Turn into a whole thing on how TurboTom is the best and FSWEKRS guys suck and blah blah blah,

Same if this were FJ you would get everyone saying FSWERKS/Randy is the best and TurboTom is terrible for one reason or another....

At this point in time asking that question on either forum since both tuners are not on both, you are not going to get a truly honest answer.

People in general on the internet are not man enough to admit the truth without bias

While I agree that a tune is the best option for tuning for specific vehicles, resetting the computer is a valid option for people with very minimal mods.

First of all, it is free.

Secondly, like you said, it resets ecu from learned parameters based on repetitive measured situations. When those learned figures have been based off a stock car, it runs according to that. Resetting for simple mods, (while nearly useless) does allow the ecu to learn based on those slightly changed measure results due to aforementioned mods. Yes, it will take awhile to adapt to be "learned", it takes less than simply leaving the battery connected and having it readjust to new mods.

Clean sleight compared to countless repeating instances...

I'd expect a tuner who has been in the game for so long to at least acknowledge that. Granted, benefits are insignificant, but for free it is viable, while a dynotune is best option.

I dont care whos tuner he goes with...

BUT resetting the ECU will NOT compensate for most changes. You can do a CAI and an exhaust and after resetting the ECU it will still run VERY lean. The stock ECU can compenste very little... mainly for stuff like different octane, different altitude, ect.... things the car will experience during normal operation. You start throwing performance parts at it and it will only compensate so much and then it stops and the normally lean condition is there.

Hence why I said "tune is best option", "dynotune is best option", "simple mods", "nearly useless" and "insignificant" but it is better than doing nothing.

I have to say you are wrong , Only thing learned is fueling , no timing is learned and most othere things in a tune are not learned , If an engine has no idea or cares what you changed it has no ability or knowledge to learn that anything has changed


Most of my customer see a change even bone stock , the emission laws are so strict now that they actually loose some power to meet the standards so YES a customer can benifit from a tune on most of the Foci out there

Taking the Batt loose does little to nothing for stock or modded cars with out turning off the adaptive learning it will just re learn your driving habbets and engine setting in about the first 80 miles and your right back where you were

Have you or anyone else thrown the stock ECU through it's paces as I have?

It adapted to the intake just fine. Added a header and full exhaust, still fine. Added underdrives, same deal. Colder thermo, same. Bigger MAFS, same. Removed A/C, EGR, P/S, same. Swapped to a ported/polished/shaved (0.055") SVT head, same. Added a COP ignition, same. Added 24# injectors, same. Run E-85, now it finally goes a bit lean but only because the injectors are maxed out (19#'s where maxed prior to the head swap).

All it takes it the operator to be smarter than the ECU to make power W/O a tune. Break things down into understandable mechanics and it's pretty simple. If you are using more air and running out of fuel use a larger injector. The adaptive will take care of the idle and part throttle overfueling (up to ~25% +/-) and you'll run richer WOT. Or you can play with MAF diameter and do the same thing. For instance I run ~1.5% richer using a SVT MAF vs my 70mm Pro-M; no other adjustments.

Well considering when a car is in closed loop is primarily driven by the O2 sensor, fuel is kinda a big thing...

Of course engine doesn't care or know what you changed. All I'm saying is that by resetting the ecu via battery disconnect it starts from scratch compared to data that is based off stock parts/measurements. So it will build a knowledge based on the collective new measurements from new parts.

Like I already said before, its insignificant, a tune is better, but for free, its at least something compared to nothing.

Saying flat out that it has no effect what so ever is just ignorant. Its a stock tune, yes its going to stick to the same tables, but because there are variances, results will vary, however insignificant and unnoticeable they may be.
