Calling 'Chip' Wes...

sorry bud, I forgot your screen name.:D

I'm making this thread cause Paul told me you can make a chip with just the basics and it's not expensive. I want a chip to just remove the rev limiter and turn off the smog crap. Can you get back to me, either pm or post on here, so we can discuss what other things we can do without worrying about a custom tune, yet.:nice:

Thanks
 
Wes did mine too. :hail2: :hail2:

I don't often say anything because I don't want the poor fella' getting bombarded with requests (he's way too nice to say no) . He donated a LOT of his free-time to do mine (I'm a real PITA).
 
Hey wes, or anyone else for that matter... Would it be useful to have a chip burnt to try to add a little more fuel when I only have a few mods? Basically I have a trickflow intake, cai, full exhaust with shorty headers, and an msd coil, cap and rotor kit. Im curious with the extra airflow, and a little extra spark if I needed more fuel? What are everyone's thoughts? Chip, fuel system parts, or leave it as is? Sorry to hijack, but I thought I might as well revive a dying thread rather start a new one...

In my experience, usually the cars need to be LEANED out unless you have a vacuum leak or other mechanical problem (bad MAF/O2s for example).

Your car is well able to read the additional air you are throwing at it with the stock MAF so you are good there, your stock injectors are able to keep up. Some guys have luck with an AFPR at the track or dyno if they can't get a chip to do the leaning/richening for them, but once you see the fine-grained control you have over fuel and spark with a chip it is tough to go back.

Your spark setup will be fine as well. I am running autolite plugs, MSD cap, coil and Taylor wires on my supercharged car at 14PSI, pulls good to 6200 where I stopped it.

However, all this being said, you are shooting in the dark unless you put a wideband on the car and find out for sure how it is running. A custom chip/dynotune could definitely improve on the spark and fuel ratios.

Thanks a lot! If nothing really NEEDS to be done than I dont think I will mess with it. I'll wait until I have more mods, such as heads, to worry about a tune. I dont know anything about self tuning, so I guess it would make more sense to wait and spend the money once on a good H/C/I combo and tune. I just wanted to make sure the computer was able to register the added airflow and compensate for it, cause I always hear about our cars running lean and pinging. I had a little ping in the summer before the mods, so that was my main concern.
 
I think Wes makes good sense with what all he said :nice:

A thing about the spark can be that ...........
during mid load driving conditions ... the spark values are very high

A lot of the time ... when you encounter ping ... dialing back a little bit of spark
is just not enough.

It takes a good bit more than you would expect to get any relief so that is
where you can get some improvement with spark table changes

Also ... at those low and light load cruise conditions you can see kinda
lean fuel conditions.

What can happen is if you encounter the ping ....
What you might do with twisting the dizzy back or upping the fuel pressure
is not enough to make all that much of a difference.

Like Wes said ... once you get pcm access you pretty much can do anything
you want as you have so many options available to you.

Now ... as far as WOT and a stock or slightly modded Stang like yours ......
The fuel table commands a fatter ratio and as the rpms climb .....
the fatter it gets.

Been a long time since I looked at an unmodified fuel table but IIRC .......
I wanna say it commands like high 11 to 1's in the upper rpms at WOT.

Now ... if by chance you are a Cobra ... you got a fuel enrichment kinda
thing going on that starts to come on line at 90mph which just makes
things that much more fatter.

Good points by Grady above.

Nick, what grade gas were you running and what was the base timing on your distributor when you had the ping? Just me being nosy trying to correlate info from others with the same "ping thing" in my head. :)
