How to tell if your tuner ripped you off
My point: Tuners should understand and utilize the purpose of High/Low Octane maps. Setting them the same is LAZY.
My point: People who pay for a tune on low to moderate boost should always keep fuel cut customized to their application. Turning off fuel cut for all customers, regardless of their needs is LAZY.
My point: People who pay for a tune are trusting their car's health towards someone they see as an expert in the field. Again, making it the "status quo" to set them the same, just because the customer doesn't know any better is LAZY.
My point: I don't think anyone questions whether or not its POSSIBLE... but if you are sending someone logs of your car, and expecting them to update your fuel & timing maps, then without proper MUT table changes, the tuner is making GUESSES as to which cells to change because they are too LAZY.
My point: It's easy to spot when a tuner simply selected a small block of cells and changed their values by a large amount, or set them all to be the same value. This type of "block tuning" is LAZY.
My point: There is no value to keeping rows and rows of duplicate cells. My beef is with tuners who don't care about those cells, and leave the duplicates there... the ECU is capable of much more precision with a 5 minute change that is re-scaling the load & RPM scales. Leaving rows and rows of duplicate entries is LAZY.
My point: People need to understand that just because they have a non-stock intake and/or injectors, they should not have to live with poor idle/cruise on cold-start or if they reset their fuel trims is LAZY.

pretty harsh, but there is truth in the aggression. some 'tuners' may be leaving some of the more intricate aspects out and only focusing on WOT.
all i care about is my horrible tunes passed all of those commandments:
different hi/low fuel/timing maps: check (quality/not an issue)
2-byte logs/megs of them: check
excel afr/timing map smoother: check
forgot to max out boost limit: check
injector/maf scaling shot in the dark: check
good to go heh. j/k

Last weekend I had to log an tuned evo8 (mods: Ecutek by an official dealer, Turboback, and some peanuts):
The Log was done only in order to see if there is some knock or it's knock-free. I was a little astonished:
Short later I checked the ignition map (to compare this map I posted to the OEM-map just below):
And what I discovered was I partial ignition increasment of 8*. For me it looked first like E85-map.
Question to the professionals: Is that knocking normal for Ecutek?

As many have said so far, the statements you have made a very, very conditional and some are just flat out wrong. Dig a little deeper into the capabilities and reasoning behind the ECU mods and tuning before making a thread like this.

Thread locked. Considering this is his first post, I wonder why this OP has registered solely to provide a warning to our members. I appreciate the concern, but I'm also skeptical. I've sent the OP a PM concerning his credentials and purpose. I'll reopen if it is clear the OP is not a troll. Thanks.
