My under hood "bug"

[Turdle]

JT you still want Scantool stuff?

I want a tune, i KNOW my 5.0L is not putting the power down to its full potential right now, but its also far better then stock!

I see my options as:
record my data, send data to a tuner and have a chip burned or program for a Supertuner thingy right?

Or full dyno session with a tuner on hand? I dont know who to trust for this, but I am sure there are reputrable Mustang guys here in CO. I dont think I would go this route until after I re-gear and finish my 4x4 conversion.

I think so Jamie.
PLEASE!!!!!!

My surging is back. I am throwing in the towel.
I don't know exactly which is the next step, but I am switching paths.

I am waiting right now for a phone call, trying to work a maf-injector swap out with a stangnet member.

I am swapping my 42lb for 30lb hopefully.
It should happen, as I am taking the brunt of the deal.
we'll see

Jamie, you still have my address?
LMK what I need to do

I am hoping this will cut out at least 1 trip to the dyno.

okay I will ship it this week

You = gunnea pig

 

[Turdle]

Cool
I have the time.

Hey, Jamie, here is a dyno locator

So
Lobe seperation 107 degrees, and this is affecting the PCM how?
I'm learning here, be gentle.

The lobe seperation affects the vacuum capability of the engine. With the lower LCA you have lower vacuum and the lower vacuum is not as stable. The PCM can see this vacuum decrease and vacuum "flutter." You can see the flutter on a vacuum gage if you have a leak in a line, bad engine sealing etc.

The PCM notes throttle position, rpm and then sees a vacuum that it knows is two low for those positions and tries to correct this by working the IAC more or changes to timing.

The EEC-V is much less forgiving than the EEC-IV in this area. There was an article in 5.0 Mustang about 3 years ago and it had several custom cam guys and they all said anything bellow 114 on a EEC-V can be trouble.

My E303 had 110 and when I put in my custom cam at 116 it was like a switch. No more surging, idle dying etc.

Brian
Please let me ask this then.
Can this be overcome with a flasher, If I can get the data?

I realize you are recommending a cam swap, however I don't wanna do that lol.

I have already had this engine out 2 times---


BTW Jamie
I know have a new user title----thanks

Brian where the hell were ya about 3 months ago! hahahaha BEFORE I welded on my radiator support...

Aww who needs it anyway.

 

[Turdle]

I gotta think this can be tuned out Jamie.

You, Section and I should get with Doug?

BTW
Way back in the day--I was talking to Brian H ( familiar ?)

He said it would take a few tries, but he was sure it was possible.

He said mod engine guys were getting more radical with good results, using eecv. It would just require someone to tweak those values into our pcm?
I might stand corrected here.

 

[410Fortune]

the $379 tuner is on my list.......

 

[Stang Girl]

I believe I have a adjuster plate on the way.

I am guessing that is what I put in the mail to you on Saturday. Hope it helps.

With all these head aches if I ever decide to build a hot rod of some sort it will be carbed!!! Including my Mounty.

I'm "Old Shool" and damn proud of it.

JT puts tail between legs and lays down in the corner now.

Nothing wrong with a carb is you like that sort of thing, and dont mind losing gas mileage, efficeincy, off road ability, your GEM module, your e shift transmission, cruise control, etc etc etc
New headaches
Old school eventually is forced to catch up because they just dont build them that way anymore.
Now with that said, Carbs are *****in and have their place, but putting a carbed engine into a modern OBD-II vehicle just creates more issues.

 

[Dan Whitaker]

Never use cruise.

C4 or C6 would take care of the tranny. Don't mind loosing OD. It would be esier & cheaper to fab new tranny & t-case mounts then having to jack with the computers.

Milage, its a Mountaineer for crying out loud

Missouri does not have emissions inspections so by by cats & all smog related crap.

I also saw the damn computers put my dad out of his job as a mecahnic. He was close enough to retirement that learning it was not worth it but he was far enough from retirement that he could no longer make a living. :fire: :fire:

 

[BrianB31]

I honestly don't know. I would think to a point within the limits of the PCM. I've been thinking of getting one of those SCT racer packages for $700, but I'd rather put that money into the engine.

A good idea maybe to call around to shops that use the SCT or other system and discuss your problem. Your gut will let you know if they are good or full of it.

Dan,
That truly does suck.
You know I think you are a great guy, so don't take this wrong.
OFF topic here
Back in the day, I used to work on tv's stereo's and such.
There was a guy I knew, real nice guy, who ran a tv tuner shop. Remember the actual rotary dial to tune channels? He rebuilt-sold them. It took quite a bit of knowhow and patience to get to his level---then in the 80's tvs all went digital tuning. He was out of business in a year.
I cared for him quite a bit, but I still like my remote control.
Turns out, he got a Job for Midland radio making more money than he ever did. His business was holding him back. Last I heard he was at Kings avionics.

Now for me
I was working for Xerox
people just don't print as much anymore, or make as many copies.
Part of why I was washed without a job search, however I still accept, and use e-mail. Gotta go with, and learn the changes.

 

[410Fortune]

Dan I see you can justify the carb conversion and thats great, no way in hell would CO let that truck on the road with a carb though (unless you pass the sniffer test and they never pop the hood!) I am pretty sure most states are like this.

My trans builder is in his late 60's, he has been building Ford auto tranny's for 40 years or so, every single year, two times a year he goes back to class to get certified in the latest and greatest......its not just engines, its transmissions, computers, elevators, copy machines, everything......if you dont keep up you become obsolete, thats just how it goes

 

[Dan Whitaker]

I doubt I will ever do anything much to the Mounty. If I do I will just rebuild the 5.0 & tranny & keep all the computer stuff.

Now my '92 Cougar on the other hand is another story. It's just begging for a 347 stroker with Pro Charger And since it has the AOD I don't have to worry about the computer for the tranny

 

[410Fortune]

that would be sweet
