Just wanted to see you write that again because I saw on another thread the other way around. Wasn't sure if you "typoed" but thanks for the reply

Edit- what do you mean not helping much past AE

I think Mark is still recuperating from his recent surgery.

Brain is still not ready to help much past AE.

So did I leave a typo somewhere that needs to be fixed?

Differant masks may have differant ways of commanding AE, there may be more, less, same?

But
AE TPS = short.
MAP TPS = Long. is correct.

No you did not make a typo, that was just a verification question.

another question for anyone. would i be abe to get a screenshot or numbers to make this graph i attached, i would like to see some curves to compare mine to. ah yes, and one of the map-AE would be great. Im wondering if curves shoot up more toward the end or a steady climb would works best.

I'm wanting to get this AE just slightly close so i can have fun still while headed toward getting that wideband(which is a ways down the road) as ive also traded my choppy for a 69 manx beach buggy project and im juggling between the two since the truck is almost complete, besides the painting a this tune.

and also from what im experiences the MAP-AE that carries the extra fuel through should be less than the TPS-AE, am i correct in this?

and mark, sounds like it was a crazy surgery, hope it brushes off not so bad.

edit/ posted the wrong pic first, dont know how to delete that one, but the example one is the AE one that is my current one

I experimented with changing the curve and didn't really notice much difference, but maybe the rest of my tune wasn't close enough yet. I did have a fuel pressure fluctuation problem that is now resolved. Currently i'm using the stock curve with actually 20% less across the curve TPS AE. Once I got more than enough fuel the stock numbers were surprisingly too much. Without the wide band it might be tough to see if the hesitation is rich or lean.

thanks alot brian, I was wondering if anyone had to go below the stock AE, and yes it is hard to tell if its a rich or lean hesitation.

scenario- sitting at stop sign, i mash the peddal it hesitates, I keep it mashed and it continues til it dies. then its hard to start, because its flooded(thats what it feels like)

I've been starting with the stock AE and moving up from there. I'm gonna start with less than stock and see where it takes me.

Also, another question for someone. i unplug the battery every time i change the chip, do i have to wait for it to learn before I see my changes from my prom?I know the VE tables show the changes right away. what about the AE, are those changes immediate?

**brian617** · 05-03-2014

Make 10% or 20% changes at a time, learned that the hard way lol. Had mine so pig rich on AE TPS that it would stall and hard start like your describing too.
