Nope I didn't change anything. I actually noticed the kams while i was driving. They were staying in the high 8'sI then all of a sudden the were bac at one working there way back down.

I pulled into a parking lot before I started logging engine was warm and check engine light flickered a few times and never did it the rest of the night. Pulled into get some ice cream it was good to go.

Fat body 30's with pro-m 80mm meter. Injector settings now are what I posted on last page I cant remember.

I was five min away from home when datalog stopped I didn't shut it off . It froze and stopped logging had to close Be. Yea at the end I got on it a little I wasn't Wot yet. I never did make me a maf shield that way im not reading fan air.

Only things I have changed in tune is thing on previous page and the few things you told me to recently. I will get on my computer tonight if you need more information let me know.know

Here you go 85_GT. Thanks for the help.

I loaded datalog in for injector slopes and here is what EA spit out.

High 30 Low 29.75

Breakpoint 0.75

I attached Datalog and tune.
I got High 29.73 Low 37.06

BP .68

That's about a 1.6% fuel increase over what's in your bin.  Doesn't quite explain why KAMs go as much as 12% and clip.  But give it a try

Observations:
You selected E10 for AFR.  Might want to try putting it back to gasoline.  I find it easier to just work in gasoline or lambda.  Did you do that because pumps say 'contain 10%...' ? 

If you leave as gasoline, then you don't have to change LC-1, tables, etc.  Working in gasoline, everything will work out to stoic being and displaying as 14.7.  Even though the actual will be around 14.08.

Also you kept egr and disabled thermactor.  Are the heads plugged properly not to allow any air in?

EA's MAF calculation showed it to be very close.  Most within a percent.

I worked late last night and didn't get on computer. What did I do wrong when I ran it through Ea.  How did you run it and get those values? I want to see if I can come up with the same.

Lesson time what you mean by clipped?

I didn't mean to keep it on e10 I was looking for them values the other night and changed it with the scroll wheel on the mouse trying to go down. I thought I had it on straight gas.

Yes no smog or a/c but still have egr. Heads are plugged. properly.

Also are my maf voltages getting that high without.going wot a concern?

I 'm going to get off work earlier so hopefully I can get on the comp and get everything on the same page.

It'll be easier to walk thru the injection slope calc with it in front of me.  Have to be once I'm home.

Clipped - numerous values in the eec have defined limits.  You want to avoid hitting those limits.  When something like KAM's get to that limit, but still needs to go more.  The EEC stops it from going beyond those limits.  That's called being clipped.  Another example is the MAF.  Once you hit the top voltage of your MAF curve, even if more air does flow, the eec won't know as it stops at that top value.

If you look at:
MAXADP   Fuel - Adaptive Control KAMRF Maximum and
MINADP   Fuel - Adaptive Control KAMRF Minimum
in the scalars tab, you'll see what the eec is using for the high and low limits for KAMs.  .88ish is the low stock limit.  If the kams get to that limit and the eec sees it needs more, eventually it might not be able to add enough fuel to switch the hego back to rich.  EEC will eventually go in to alternate fueling strategy which is probably what happened.

No concern on the maf values.  You were actually fairly high in the rpm's.  In the 5000 range.  Load values show you were at 80% so you were pretty near WOT even if the pedal wasn't  Looks like it was around half way.

Maf voltages still have some to go before they are far clipping.

If anyone is reading this. i had electrical interference with Quarter horse it ended up being my spark plug wires. Taylors wires have some issues with computer controled things like dynos and quarterhorse.

and here is a datalog

I had forgot about it until you posted that, but I had a friend that had similar issues with Taylor wires. That was years ago, would have thought things had changed.

Anyway, we just used FMS/FR wires on efi cars after that. Just one less problem to worry about.

Yea I talked to local tuner Bob monks aka Bobcat. I told him what it was doing he says I know your problem your car has Taylor wires on it doesn't it. I said yea very skeptical at first. Then he gave me his experience with them. Tried it and that was the problem. He said every car that he has ever tuned that had them he has had problem with.
fms wires work good.

Now I need to get this bitch dialed in. I need better gas mileage and more power. Plus it seems my afr is kinda all over the place. Anywhere from 15.5 to 12.13. I want to learn even if it kills me.

Thanks

I'm glad that you found your problem with those nasty Taylor wires.    Smiley

First one from sat night
second is from tonight I changed injector parameters and cleared kams
Third is me playing around a little bit i was excited i could see what was happening again plus its was a good night to give it a little gas.
