Re: Auto tuning
That is so true.
Anybody wanting to learn to tune, DONT wait for this stuff. Yea it will have some new features, but learning on old stuff isn't a lost adventure.
The autotune HELPS with 1 table. As people know there are ~100 tables you CAN play with. Several constants, etc. Granted you could count on 2 hands the ones you use 99% of the time.
We are slowly adding in filters to tunerpro def. files also. So a beginner can turn a filter on and see just the important tables needed, hiding all the rarely touched tables.
I have put up some tuning notes, if someone wants some more, specific topic I will see what I can do. If I don't feel comfortable then I will get someone that is.

Re: Auto tuning
That is SO true. I am not a very experienced EFI tuner, but I do know how to tune a car the old fashioned way. I have somewhat tuned my Procharged Vette, and I have recently been toying with the Ty as many have read.
The bottom line is that no tuning program/software will totally tune your car. YOU still need to know why you want to change things, by how much, and in which direction. Using a datalog and even a wideband are the tools you need to be used to using prior to burning a chip, or changing tables with an emulator. This new software sounds great, make that amazing! but I wont make a tuner out of everyone. For all those excited about using this stuff, get a head start now by using what youve got. Get some software and a cable and start logging. Look for trends in your logs, and make a special note of problem areas. Start with general driveability, and work your way into WOT. We are all here to learn from each other, post your findings or questions and we can all learn from it.

Re: Auto tuning
We are still moving forward. Just finished up on revision 5 of the autotune software. The couple alpha testers have had good success and after each autotune the truck runs better and better.
I am hoping to have Jeremy's truck running the new code for nationals and will gladly demo the new chip, features, autotune, how it works etc at nationals. If Dig can make it to nats, he will be even better teacher (i will make sure everybodies drink is full, hold flashlight as he talks).
We are working on a new site just for this chip (since it really is a development on it's own), and once it is ready for operation will keep news posted on it, and be ready for more beta testers.
Maybe by nats we can have first public release of version 1.0 Bring your laptop, cables, ostrich just in case.

would this autotune work with 75# inj.?

Re: Auto tuning
The concept behind the autotune deams it to work on all combinations.
You will need a base chip that is close to start with. It needs to idle, and drive on it's own. You basically go for a drive, and make a log file. Dump that into the AutoTune.xls, then get the changed values, and input those back into the chip. Lather. Rinse. Repeat until tune is VERY close, and most likely better than it's ever been.
The combination is not a factor in the ability to use AutoTune. I am having thoughts of putting a 7749 on a custom turbo motor project simply to test/play with this software. It will be a 4cyl, with 33# injectors, and a GT28R turbo....Not even CLOSE to a stock Sy/Ty chip, and I have no doubt it will work flawlesly

Re: Auto tuning
As Mike said Yes. It really doesn't know what size injector it just takes data (the more the better) and averages ACTUAL afr from the wideband sensor. Based on this average it will adjust the VE table. How much it adjusts is user adjustable. 75lb inj. would need about half as much as stock, etc.
It bases the average from a new desired AFR table. So you can have a lean cruise, and boost where you want, etc etc.
When your done if you choose you can turn the closed loop wideband on, to let the ecm further adjust real-time, again to the new DESIRED afr table, not just 14.7

Re: Auto tuning
wow, i'm really excited now
wow, i'm really excited now
Re: Auto tuning
Man i get more and more excited about this with every new post i read, i cant wait to play with this new software.
I also have a question for the gurus?
I know that the 7749 can control a V8, but what about using it to control an LSx Gen 3 or 4 type engine? with the individual coils and such?? With all this new tuning, and my plan to make the LSx engine swap in my SGT turbchagred, this could be a nice way to go for engine managment, and since im going to be runnin a T56 trans i dont need trans control at all. This could be much cheaper than buying an aftermarket setup.

Re: Auto tuning
Jeff, thanks for taking the time to meet with me Wednesday...the software looks fantastic! I am hopeful that this software conglomeration continues on its path...lots of very interesting things to come! And how cool would it be to have more of our trucks actually running "well"

Re: Auto tuning
Might be what we need to get the resale value above what they cost when they were new.
People will want them more if you can say yeah it pretty reliable and it only took us 15 years to work the bugs out!!! :rotf:
All kidding aside I again really appreciate everything you do to make these vehicals perform optimally and the fact that you are willing to share the info without anything in return shows that your character is above and beyond the average persons with dollar signs in their eyes and having no passion or understanding to do something because they just love it.
Thanx

Re: Auto tuning
You wouldn't be able to run the full coil setup in the native form. Nothing stopping you from
running E-dist with it, though.
We will be adding further features, down the line, but the basic ECM hardware limits the
amount of things that we can do. Only so many inputs/outputs....

Re: Auto tuning
This is the subtle truth of tuning these things... either if you're doing your own, or tuning
someone else's. 90% of what you do "tuning" is fixing the things that are broken.
In the 12 years I've been doing this, I've yet to get a truck that didn't need something
fixed before the actual tuning could happen.
While the auto-tune stuff makes the process a ton easier, it still won't eliminate the need
to be able to diagnose and fix problems. There are no magic bullets for that.
