How does EcuTek/BRZEdit handle the closed to open loop transition? What are the options as far as changing it?

This. It's my biggest worry. I don't drive the car outside of giving John a log and taking it to the shop for supporting mods. I really really want to drive this car without worrying about it knocking. The original plan was to get the 91 map looking good then switch to E85 right away, it's just been weeks into the process for 91

Yep... E-tuning can be a B*tch....

The thing is, it should not be. These big name tuners have done enough of these kits now that they should have a very conservative basemap that does not knock the engines to death while your trying to get the tune dialed in a little.

The thing I am most disgusted with in all the various logs i have seen (i have seen logs from many FI tunes from many tuners at this point, this is not directed at this car alone) is the fuel trims... it's so easy to fix yet instead they just turn off the DTC for maxed out fuel trims... I have actually seen combined idle fuel trims of 50 to 70 percent... there is just no excuse for that.

Replied via PM, since t00ners are getting pissy about their logs being viewed i don't feel inclined to share any more info than i already have, someone might actually learn something.

i'm having mine tuned locally (not e-tuned) and even that is turning into a long process. tuning is a bitch, which is why i think every person who owns one of these cars (FI) should know, or be willing and able to learn, how to tune it themselves. i've found that we do ourselves a great disservice by not fully understanding the very most important part of the setup. there is far too much reliance on (often sketchy) outside help to make these things run right.

teach a man to fish...

This is very true. While I have had my car tuned by both Visconti and Toni, I still want to understand everything about how the car is tuned. I want to know what changes are being made to fix things. Visconti was not very forthcoming with his changes to my tune, and it pissed me off. Toni has been a little more forthcoming in fine tuning things. I really wish EcuTek was user tuneable.

it all goes back to the root of the problem, and you nailed it. the ecutek model creates dependency between end users and tuners who paid their entry fee. they can't let you tune it, or you would no longer be beholden to the 'masters'. a few years down the road when things need adjusted to compensate for changes, different fuel, whatever it may be you can either (hopefully) find the original tuner and have him update it or throw the whole damn thing away and pay someone else to start over.

unfortunately it doesn't matter how forthcoming the tuner is or how much they're willing to divulge about the work your paying them to do. you have no way of doing anything about it anyway with ecutek. they've got you by the balls.

My personal opinion is that tuning these engines are not that difficult using EcuTek (have not used any other software yet). With that said it can be very time consuming, there are a lot of maps that need to be touched in one way or another. As well there are a lot of different ways to skin the cat so to say, each tuner will have there own way. The only codes I have ever turned turn off are secondary O2 sensor, start up timing, catalytic converter, and the evap ones as the system inputs and out puts are used for something else now. I will also agree with Mad_sb fuel trims need to be adjusted properly as over time those can throw a tune way out of whack (from what I have seen from many other types of vehicles). I can say with out a doubt I will for no reason get involved with email tuning these things and only do cars I can put my hands on. There are way to many variables for me to feel comfortable with the email stuff. With that being said there are plenty of people who appear to be very happy with there email tunes and are having great results, so there are some tuners that are comfortable doing it and they are doing it well from what it seems, I have looked over no other tuners logs as I am not interested. Just my 2 cents on the topic.

Sometimes the logs came out worse than before and worse the before last. The car hesitated to go, logs showed a good amount of knock values, AFR was pig rich. Again, all of this was done with the hope of a Dyno Day to finalize a safe, PROPER Tune.

In total, I flashed 16 E-tune files before getting on a Dyno.

The last straw happened when I was cruising one day, heard something strange, turned off radio and A/C just to notice that my car was LOUDLY knocking at cruising speeds. I literally feared damaging my engine with these tunes, I stopped using the car. If it weren't for the fact that I DONT Daily Drive my car, I would have lost it... That day I had it. I realized how stupid it was for me to keep waiting.

This almost exactly sums up my experience thus far. Tons of knock correction, pig rich, knocking at cruising speeds. Incredibly depressing. I sent John an ecutek log w/ the graph I showed here plotting boost and AFRs Monday night. Progress is incredibly slow. I'm hoping to get a revised map back from FullBlown to finally make my car drivable.

If I had to do everything over, I would've just shipped the stock car to Minnesota for FullBlown to install and dyno tune. I'm still stuck with a car that I only drive for short distances to log a new map, then park it till I hear back. I can't imagine how people deal with this when it's their only car.

If LJ had not been moving buildings at the time, I actually had a 20+ hour trip up there planned to have him tune mine first. As I have said before, face time in front of a tuner is always best.
