May have solved 100% E85 on LNF puzzle

Update
I was able to increase "regulator command" but it had no effect on the pressure drop which tells me we're either at a mechanical limitation, there's a restriction somewhere, or maybe my car has a weaker low pressure pump.
However, I did make some adjustments to my tune - I was running a pretty fat PE ratio for testing purposes, but I leaned out to .86 and then .88 lambda. I was able to run stock fuel rail pressure and do a full 3rd gear pull with no loss of fuel rail pressure and 100% E85.
BYT, IamBroke, Matt, I'm going to incorporate these changes into the layer and send you guys updates, I'd like to see what kind of results you're able to get. The injection timing stuff alone seems to have made a really big difference.

BTW you left out a couple of lines from your email R*%$
Why is it you left those lines out? If you are going to post just post everything, but yeah I don't like being talked down to like I'm the local punching bag theres really no need for it.
We've been doing this for a while and god willing will be doing it a while longer but theres only so much we can do with the limited amount of good engineers that are out there.
I'm sure Vince would probably tell you he works 50+hrs a week and that even at that he's probably backed up with work...same here. We do the best we can with what we have.
Sorry Vince If I've in anyway hijacked your thread but we work our asses off over here so I feel there was a need to defend ourselves a bit.

No need to apologize, everybody is giving 110%. And you're right, I have enough work here for the rest of my life I think. ;-)

OK so 2 of the 3 major players in this game are on the same forum, even talking to each other, and can't work together towards the same goal? I don't understand this, I keep hearing all you guys are working your asses off because you have so much work (which I would think would mean income) why can't you hire more help or team up and work together? The basic business model here doesn't make sense to me. If you have more product (tunes, hardware or licenses) demand than you can deliver, than you have to figure out how to produce more product. You can't tell me there aren't any software engineers out there can do this stuff, where I live there are thousands of them all looking for work. Hell, I'm betting you can get people overseas to work on this stuff for a buck an hour if you wanted. Hmm, here's a thought, maybe somebody in GERMANY could work on this? (lol, I bet they'd know a little about these Bosch ECM's, but they wouldn't work for a buck an hour!)
The only other explanation is that there just isn't enough demand for this "product" to pay for enough support and development. If that's the case, which I suspect it is, then I actually applaud you guys for putting in the hours you are because I'm betting your hourly wage is well below what you'd be worth doing something else. That means you're doing it for the satisfaction of being a part of this community, and not to get rich. If that's the case, sorry I'm stirring this up. I want to thank all of you guys personally for giving us what we have on this whole tuning thing. I know all of you have put a lot of time and money into what you do and I for one appreciate what you all have done. I've worked on cars longer than most of these guys have been alive, and believe me, sometimes it gets a little old. The fact that you, and others out there too, have given us the power to control these systems has made working on cars fun again, for me at least. Think about it, I grew up having total control over how an engine ran, carb jetting, point gap, etc. There was a period of years when we, even as techs, had almost no control over how an engine ran. Getting that control back (for as long as it lasts that is until it all gets taken away again by the greeniacs and gov) is pretty damn cool.
Wow, drifting a little off subject am I? Sorry.
Here's the bottom line as I see it, which I know is really little to none of my business to give you guys advice. If there's money to be had out there by supporting some of these ECM's, and you don't have time to do it, hire some help. If you can figure out how to team up together and share knowledge I would think you could do it as a win-win if you think about it enough. Nobody has to give away years of development they've created, it should be worth something. But if someone else needs that development, and it's already been done, why wouldn't you try to buy it instead of doing it yourself?
If it is that there just isn't enough money in this to hire more help or buy someone else's work, then thanks again for all your efforts!
Thanks guys. Sorry for the long post. And sorry to pollute your thread Vince.

When hiring outside of the industry it takes about 6 months of training just to get them up to speed not only on our system but what they are doing as this is like no other engineer job most will ever do.
The only other explanation is that there just isn't enough demand for this "product" to pay for enough support and development.
I'll give you a for instance we offer support for the following vcm's
A40-head engineer
A40b-head engineer
E37-GM engineer 1
E38-GM engineer 1
E40-GM engineer 1
E55-Head engineer
E67-GM engineer 1
E69-head engineer
E77-head engineer
L4-GM engineer 1
L4big-GM engineer 1
97V6-GM engineer 1
98LS1-GM engineer 1
P01-GM engineer 1
P59-GM engineer 1
P04-GM engineer 1
P05-GM engineer 1
P10-Head engineer
P11-Head engineer
P12-Head engineer
T42-Head engineer
T43-Head engineer
NGC3(dodge)-Head engineer
NGC4(dodge)-Head engineer
JTEC(dodge)-Head engineer
Ford(1024k)-Ford engineer 1
Ford(1472k)-Ford engineer 1
Ford(2048k)-Ford engineer 1
Before you say we've taken on more than we can chew check out the supported list for both vince & the 3rd party to the market and their supported list is nearly as long as ours.
When doing reverse engineering you'll find most companies such as ours will release all the necessary tables to get a good tune, contrary to popular belief most tuners will only adjust between 30-60 tables anything above that is usually left more to the tuner that has an unlimited amount of time on their hands to try tweaking and adjusting every table such as GM which might get 1 or 2 full years to get a tune correct. We don't have this comfort to spend 1 or 2 years straight to reverse engineer every single table in a pcm.

We hired 3 new engineers in the last two years, 2 do our calibration work, one is working on the software end of things and still want to hire a couple more HPTuners.com >> Performance At Your Fingertips the problem is finding more near our facility or willing to relocate there but I've said several times in the past that we are all ears.

Tuning a car is much different than looking through the eyes of IDA but if he's got the background anyone is welcome
I did a good amount of tuning in my day but I don't think I could ever do what our engineers do.

so PLEASE start working for HPT full time/part time.......and lets get this thing rolling!
Maybe we can have the fuel pressure table and other tables open if you help out the other HPT engineers .............in a month or two?????
