E2O 5/11??

[331lx]

I had a pretty good time down there last night. 10.95 and a 10.97 @123. More than anything I was there to work on my lights and finally they are starting to come back. Managed a.028 and .006 on those two 10.90 passes. UMTR starts next Saturday.

Nice runs steve, I'm taking it you got your trans issues resolved

Yeah I tore apart this week and fixed it. I just need to get my tune figured out now. Car still has plenty left in it. UMTR starts Saturday and thats my main concentration right now. The car is running super consistent right now so as long as I can keep lights like I was last night I should be good. Before we started playing with timing and carb stuff last night. My first 3 passes were 11.049. Cant ask for much more than that when it comes to bracket racing.

Yea no doubt consistency is key and it appears u have that down

Thanks for the great pics that damn hatch I didn't even know it came up

NO prob. You want them PM me and I will attach them.

What a good time last night. Great to see alot of guys out.

I feel like a total heal, I guess that is what I get for thinking I was going to beat my PB Last weekend, the car felt GREAT, last night, no so great. Just amazing............

First pass out, tank had too little fuel in it and running E85, the pump is pumping 30% more, so on the top end, I ran VERY lean, like 13.1 lean, which in turn caused all kinds of KR.

Second run, add 5 gallans more fuel, added 5% more fuel to the fueling table, Dropped timing down to 23 Degrees, 1/4 way down the track, 12.6 A/F, so I let out of it.

Third Run, we added 5% more to the fuel table, made a full pass, with 12.1 or so A/F, but now the trans feels strange and the car falls on its face on the top end. Come to find out, I was seeing a TON of KR again.

I had put shorter upper motor mounts on the car, and was thinking that it was causing something to hit to cause this KR, since the rest of the log looked fine. So I took the stock ones off a friends car to see if that helped.

Fourth run, car felt OK, shifts were a little slow, A/F still around 12.1, 12.0, and at the end of the track my rpms hold and the car falls on its face.

Look at the log, once again, KR on the top end. Upper mounts did not help

Fifth run, added a little more fuel, dropped timing a little, still same reasult. After talking to my friend on the phone who helped me tune it, he seemed to think that the TQ converter is shot That it most likely has "ballooned".

So today, I get the car on the lift, take of the inspecting plate for the fly wheel and see paint is missing off the TQ converter, there is metal dust in the trans housing, and the flex plate had rub marks on it.

I would have to say, I fried the TQ converter/ballooned it, which in turn was making the flex plate, flex too much, which in turn was causing it to hit the block and the rear cover bolts, THAT is why I was getting a TON of Knock Retard on the top end. AH, problem solved, well kinda.

SO guess what I get to do again, yeap, pull the motor AGAIN, and put in a different TQ converter, this time I am getting a High Performance custom converter with a billet cover. It even comes with a 5 yr warrenty and rated to 1000hp. That will solve that problem, or at least that will let me see the next weakest link that my car has.

How are you measuring your a/f ratio? You cannot go by a classic gauge because of the stoich of the fuel.

You really need to be measuring lambda on the car

most widebands are using a stocih of 14.64 (pump gas) times the lambda (what the sensor actually is reading) and thats how it comes up with a/f

e85 will have a stoich of around 9.7

should be shooting for a lambda of around .78 to .80

I am using a Innovate LC-1 Wide Band controller and gauge, and lambda does not change with fuel, since it reads lambda 1.0 is stoich regardless of fuel used. So I can still use the same A/F valves as gasoline. I would have to go into the controller software and change the multiplier. If you change the fuel but dont change the multiplier you would just continue to aim for the same AFR that you did with the old fuel. With that being said, I am still trying to get around 11.8 to 12.1 A/F.

Brandon, thanks a bunch, great info right there.

Oh and in that artical it says this too:

Quote:

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.
