using 14.047 for desired AFR and not 14.63?

Hello CalEditor,
Thats cool. Just wondering if the customer knew he or she bought E85 or was it a fuel at the station switch? Did they Charge the for a new MAF. LOL

Actually I was by Technician B's area and saw an LS1 MAF on his bench and asked why it was off the car he was working on. He said Technician A asked to try it on the Escalade he was working on, so No they were not charged for it

Did the customer know he had E85? I was kidding about the MAF charge, I have a pretty decent Idea that you would never be around a place that does that. ANd I mean that as a very high compliment.

NO and from my understanding GM says to run the tank out now. You don't need to drain and refill anymore.

funny thing was to me I was telling Technician B that it is all math and he was looking at me strange.

Fuel Flow Rate = MAF X desired AFR

7.xx g/sec@ idle is stock, the Injectors are stock, tune is stock, and the truck is running so the fuel pressure is close to stock. Then it has to have E85 in the tank.


We only have one fuel pump issue period
That would be on the ESV's. The line in the tank rubs on the tank module and it gets a small hole in it, but that makes for a hard start.
I just know from experience the pump was A OK and it was.

Did you mean this:

Fuel Flow Rate = MAF * FAR = MAF / AFR

Hey Joe,

How have you been/ Well I hope and the Cat thing is ok now, i hope.

I think it goes like this.
Fuel Flow Rate= MAFxAFR(stioch)=MAF/AFR(stioch) and assumes gasoline stioch for the type of non flex fuel vehicles PCM?
Is this correct?

Fuel Flow Rate = MAF * FAR = MAF / AFR

Hey guys,
This has been a great learning thread for me so thank you.
I stumbled upon an article today that really helped me understand the bigger picture of all fuels including gas.
Especially with the new Flex fuel cars and the VVT, VE, Coefficients, the Zones spark and on and on. It is attached and is an easy read.
After reading this I might even try to mix a little water with ethanol.
Take a look at the attachment and let us know if this help better understand the newer systems. It did occur to me that they thermal zones I think and their coefficients as to vaporization of whatever fuel we are using. A thermal Zone and VE WOW!! Plus it show the energy potential and advatges and disadvantages. Even VE and stoich!!

I saw that you are from Washougal. I like Washougal. I live 45 miles east on the WA side and then up in the mountains.
I think that Chevy366 thinks that I was making fun of Country folk because of the granola head label you get from fox news about the NW. I don't think he knows how many of us country folk there are in or from the NW.
BTW there is a somewhat new tuning outfit in Washougal I have heard some Ok things about.
I run into some of there customers at the races. One guy has a 07 ZO6 that he claims has 630 RWP dynoed by them. Thats around 700 hp+ at the crank on E85. His only improvement are a cold air intake, Headers and a Cam and only E85. LS7 injectors cant handle that not even close. Your earlier post (and link) in this thread exposes the guys that make these types of claims. There is no way the fuel system, pump, injectors especially can support that on E85.
I do not know if it is the tuning shop or the customers as I have heard good things about the shop. We just do not have very many tuners out here in the NW and you could do very well here. Something to consider! Also allot of us hot rod guys out here have Harleys too.
Maybe we could get Chevy366 to move out here too!
Take care in the City,

No way , I thought you typed that corny Hick style real well , shows .
We are looking to move , might just do that , then you would be my Neighbor and Buddy right ?
I think Greg doesn't realize that most people on here tune with EQ and not AFR , I know I have for a long time now , much easier , so Lambda is not that different .
What is strange is we have E85 cars and trucks in Texas , but no E85 stations in the area .
E10 is it worth the time and trouble ?
Or is GM close enough ?
And does B3601 make a quantifiable difference ?

I had changed to the 14.07 AFR in B3601 a while back. I tried I have tried LAMBDA and EQ.. I am not use to LAMDA so I have to give it time to be fair.
The change to 14.07 made a very big difference and my car is happy!! Would love to have you for a neighbor!!! I am a redneck and proud of it!!
I really could hunt from my deck, no kidding. This morning we had dear and turkeys on the property. I have been all over and the NW country is a great place to live. It has a liberal label because for the most part we try to leave people alone and if they are weird ,oh well, I dont want the Gov. telling me how to live. Not to many tuners out here. I get allot of snow most years.
My son has 80 kids in his whole senior class. We are about 70 miles from the big city, not to bad. I really did raise cows, horses and sometimes pigs.
That was no act, sorry if it offended you as I really like Jeff Foxworthy and was really poking fun at myself. If you ever need help finding a place out here give me PM and I will forward you my info!!
We do have a few places in portland that sell E85 but none around here that are suppose too, even though I seem to have received some.
Did you look at the attachment?
Thanx,
