Re: Project Never Ends

AFR and Lamda though are different.

From this link...

They have a table.

Showing AFR -vs- Lambda for each fuel. Lambda is always 1.

So even though the PLX is showing 14.7, it is really lambda of 1, and in E85 world would be 9.7:1 AFR.

As I saw in my truck in order to get the afr back to 14.7 on my plx gauge (lambda 1) I need to add fuel.

So it all "works" just the AFR # now is not accurate but in some ways makes it easier to remember gas AFR #'s.

Re: Project Never Ends

Thanks for that article Dobrick

Doing some more reading from that article gave me this nice nugget of information:

"O2 sensors (incl. widebands) don’t measure AFR, but Lambda. Lambda is defined as actual AFR/stoich AFR. It's a ratio. In closed loop part throttle the engine is just running at Lambda 1.0, regardless of fuel. "

That is why the PLX reads the same with e-85.

Re: Project Never Ends

Another good quote from

www.e85mustangs.com

"If you already have a standard gasoline AFR meter hooked to a wideband O2 sensor, you can still use the displayed gasoline AFRs in determining your engine's true AFR. For example, if your gasoline meter is showing 14.7, then we know this is Lamda of 1.0. The equivelent on the E85 side is around 9.7. Therefore you can conclude that the 14.7 you see on the gauge is a true AFR of 9.7. This allows you to effectively use existing gasoline AFR components or software to tune an E85 Mustang without buying special equipment. Simply use the same target AFRs on your gasoline gauge that you normally targeted for gasolline. "

Great site. It looks like I will never get true e-85 here in Denver... I will always get a lower blend... It is right on the -105 longitude...

Still much better than race gas!

Re: Project Never Ends

Wow, after last nights starter ordeal I adventured out tonight minus any co-pilots and got brave hoping I wouldn't have to walk home. Sure enough I didn't.

I will say when I left the tune was ROUGH. Not like I had any base chips tunes to start with on this one. Add in 2 extra cylinders, e85, 84# injectors, well you get the idea.

Passed 2 cops, 1 was writing a ticket to someone. The exhaust although quieter than a lot of ricers is not sneaky quiet at all. Sounds good just not stealth so hoping they leave me alone.

Did 3 autotunes, wastegates still at 4psi. Got my first somewhat boost launch. HOLY CRAP is all I can say, 6 yrs of work was worth just that one launch. 4psi launch, ~30% throttle and it felt like jeremy's truck at 16psi launch. Not by any means the fastest truck I have been in or driven at that level, but when you are expecting 4psi launch and truck has you pushed back into the seat and your eyes even further back.

This is going to get interesting I can tell.

Bad news is the motor may need to come out again. Oil pan is leaking, and got a noise the appears randomly at idle I a want to find ASAP. Not sure what it is yet, hoping simple but might get another ear to it. If I pull the motor to fix oilpan gasket leak, might just take a look back inside the bottom end of things.

But damn I got some motivation now and adrenaline running.

Got some crappy 1 handed video while driving also. Hopefully have it up tomorrow for you guys.

Naw, glad that it is coming around. Just wish I could help more. I still want a ride in it! It has been 6 1/2 years since I last rode in it. When are you planning to yank it out?

Oops. Better rephrase that before Dobreak gets excited. When are you going to pull out the engine?

The V8 would have been more work and has it's own hurdles to get over though. Everything has good and bads.

yeah but the fun factor leans heavy toward a v8, oh well maybe i'll look for a syclone shell when my ty is done

Re: Project Never Ends

Had Jeremy over last night. The noise I am hearing he is confident is not internal to the motor. Last time he rode in the truck was 5yrs ago as it was spinning the main bearings though so I am not sure how much I can trust him yet.

Made a small diversion change of plans though. On way to get some food last last truck felt like it was getting low on gas (gas gauge isn't working yet for some reason and on the to do list to troubleshoot). Being I was not near the e85 station, I put 5 gallons of 93 in it.

So much for tuning, as that obviously mess things up and truck was running so rich when I shut it off flames shot out from under the truck.

So I think I have made the decision for now to go to back to gas which I am more comfortable with long enough to get the tune dialed in for gas. Will give me more options for gas stations for now and I wanted a gas tune to have anyways. Once I get the gas tune and all the truck bugs worked out back in with e85 and hopefully a lot less bugs to work through.

In the end would like a 100% gas, 50/50, and 100% e85 tune done for it.

Still leaking oil though, got a couple simple things to try first before I resort to pulling motor out.

I did get the gas tune to idle decent last night, had to take almost 60% VE out to make it work though.

Got the 4 wheel line locks hooked up last night. Have not got to try a boost launch yet with it, but did some mild testing. That little button is going to be fun and interesting.

Ostrich multichip. Have an XDF with the fuel tables at 16 different locations. Use the G3 switcher to switch based on alky % . 16 bins gives you 6.25% resolution.

There's also the GM alky % sensor that gives a PWM output based on the alky in the line.
I don't really want to make more work for myself right now, though.

Works better with better brakes, I'm sure. You can actually pump the brakes up, hold the button, then pump a bit more, release/hold button.

It seems odd to spool it up without a foot on the brakes...

Yea, multichip might be the way to go in the end so I don't need a laptop to switch between them all the time.

But for now I gotta stick to 1 gas and tune. Getting 1 right with this odd ball combination is taking more time than I thought. Autotune isn't so good when things are dynamic and way far off to begin with. On the flip side Jeremy said now that he is running code59 it is running better than the race chip ever did, and he only has ~2hrs of tuning since the switch. I am far past 2 hrs and idle is OK.

So Dig you are stopping by on your way to texas right?

The 13" C5 brakes up front and ls1 calipers in the rear so far appear to be working well. I have not PUSHED them yet, but they stop when asked to so far.

I should also note the PCS tranny controller and transmission itself has performed flawless so far. The only tune I have done to the transmission is the wizard setup that the PCS will ask you when you first load it up. That was couple months ago. I will make a few tweaks but the base shift points it install from just the wizard are not bad at all. I have yet to hook up to the tranny to monitor anything. It just works, so atleast 1 thing I have not had to mess with yet. :tup:

Tuning is perception. The more you do of it, the pickier you get about it.

Initially, though, better to not have so many variables. Pump gas changes enough from tank to tank, and you have the upcoming blend change once the weather gets warmer.
(Watch for it... your tune will know when it happens)

I'm sure the pilot wouldn't mind a 800 mile detour to Hillbillyville. They probably do that kinda stuff all the time.

After 5 months of continuous sub-freezing weather and 6-foot drifts in my back yard (it's still there) I'm really not so interested in places where it's not at least 70.

If you need me, I'll likely be in one of the public courses in SA, or one of the junk yards.

Description is wrong:

1) It didn't mention the Chuck Taylor High-tops.
2) Pall Mall or Kools for me, thanks.

All I can say is, if it weren't for the 727-100, I couldn't afford a Syclone.
I'd have a Ty too, if it weren't for the damn Cooper Vane.
