3.8 v6 Mustang.. Turbocharged with steep gearing(4.56) PICS!

[Stang95]

I've been working on this for a year now.. just need to get the adx file. I have the A4X3 bin, just need the adx now. TunerPro .

But here's what i'm working with.. :


I'm contemplating hood scoops but i kinda like to see the turbskii .

4.56 gear with a "mini spool" i guess i'd say. (welded spider gears). I can remove them at will.
Still stock tire size.
Standard T-5 transmission.

Not done with the exhaust yet. Will have it side-piped in front of the rear tires.

This car ,even without a tune will spin 1st second, and peel a tad bit of third if i rev-drop from neutral. I only have the turbo on bank 1. Might change it up if it doesnt spool like i want.
The wheel-hop is insane. I'm glad nothing broke when i tried to smoke the tires( before turbo):


Just did dual-piston front brakes with a hydraulic ebrake.
Everything was done D.I.Y. , junkyard, used, or cheap parts.
Total cost of everything is less than $1,800 including the car.

Are supercoupe rods and pistons a "drop-in" thing? I can get a full set of those ,used, for $120. But i first need the adx file for the ccaqe/a4x3 .

I just noticed the other day.. in my school years when i felt like drawing a car it looked like this. Just didnt have a turbo because i didnt know what those really were at the time.

Anywayyss.. When i get my brakes bled i'm going to try 91octane gas with octane booster. Will try to not go past 5psi but if i do hopefully the extra octane will protect me. like i said.. no tune/no adx file.
So ready.

[Stang95]

So i just learned to read the stock E.C.U.
Since i dont see any adx specifically for the A4X3 i am checking out different years of 3.8L . This one is for the 99/2000 Mustang. Would this be o.k. to upload to the ECU? It just doesnt seem right. I AM STILL NEW TO THIS so i can be wrong.

[decipha]

no you cannot run a cvba2 or any 4 bank strategy on your "1.5" bank ecu. You must run a ccaqa or ccaqe tune

there is no adx file for either of those strats, and I never released my xdf file for either strat as well

the single bank turbo is interesting, im curious to know how it performs

the supercoupe rods and pistons are junk

yea its best you only run premium fuel in a boosted vehicle

If you tell me what injectors and maf you have in her I can post a startup tune for you that would be much safer to run around on now for the time being until you can get it dialed in, I can post a limited xdf file for you to dial in the maf to get the fuel correct, no logging though as i hadn't finish it since no one wanted it.

Your best bet though would be to get a full custom remote tune http://www.efidynotuning.com/remote.htm

[Stang95]

i would like that so much. I will be able to see what things should really look like.

MAF-wise i haven't been running one. Or an IAT.
The car still runs good,although can smell the richness while driving. Could be the 4.56 gear helping out. When at idle i need to hold the throttle above 1k RPM to keep the plugs healthy.
But since it will be seeing boost i am reinstalling them.


The car is running 19lb Bosch injectors which i believe is plenty enough to just to get out of HG and into at least 5psi boost for now.
I wonder if it can touch 6. I'll need to look at how the timing reacts to 6 to see if it knocks with my OBD2 scanner. Then i may try 7 maximum if things are o.k.


Running the Stock MAF as well. It's a little bit bigger than 3" . The previous owner may have installed a different year MAF. The car has a 97 driveshaft that clearly says "97 mustang" written in yellow which tells me parts have been replaced.

[decipha]

six 19 lb injectors will only support 150rwhp on a boosted application, you will need an FMU with a 10:1 disc in order to make that work, best bet is to just put larger injectors in it. If you look at the chart on the homepage in the pre tune info you need at least 30lb injectors minimum if you go that route. Would be cheapest to see if someone is selling a set of old supercoupe injectors. Also worth noting. On a bone stock supercoupe with 30lb injectors, they lean out after 230rwhp. I cut a new custom crank pulley on my cnc machine for my supercoupes and just that pulley alone pegged the stock 30s on a stock supercoupe just a little FYI. You can also try to score some 42lb injectors from a lightning or harley truck.

a stock 95 v6 should make about 140rwhp on engine, on 5 lbs you should be near 180rwhp or so, maybe 200rwhp is you designed it well

knocking is the least of your problems, lean out would be the big issue

the maf should be fine

[Stang95]

I drilled out my stock 19lb injectors twice the size and still have more room to drill before they match the pintle. Pretty sure they will flow a 40 now. I cant afford big expenses right now. I'm not sure if you've heard about the effectiveness of de-capped injectors, but they work. Might mess with the spray pattern barely but they work.

[decipha]

yea the forum moderator here has done it, search for his post he will prob have some values to get u started

cruising around with decapped injectors in fail safe mode will destroy that engine i can promise u that if u hadnt hurt it already

[Stang95]

im not on stock 19lb injectors though. Im using bosch, ethanol compatible injectors.
I replaced the stocks a year ago when i thought they were bad. turns out i just have 4.56 gears which slows acceleration due to wheel-spin..



No way would i de-capon an engine that doesn't need it. Bad enough,when i had a turbo mid-mounted, i actually installed the MAF sensor its-self(not the MAF holder) into a 2" intake tube and it had the turbo SPEWING fuel out the turbo at mid-high RPM. and thats with 19lb injectors ! Thats why i thought 19#'ers can do more than people claim.

[decipha]

19s are stock size injectors

well yea putting the stock element in a 2" pipe will peg it at like nothing, that will cause the injectors to go wide open

no you thought wrong. Its not what people think or claim its simply physics. Impossible for 19lb injectors to spray more than 19lbs unless you make them flow more some kind of way.

The worst part about this whole tuning thing is nobody mentions needing to purchase the start-up file.
Plenty of info out there to tune but when it comes to just being able to turn the key and start the car its VERY difficult.

I know whenever i buy the start-up file i will be selling it for like $50 a person because i went through 2 months of research just hell to find out it isnt free..
Now if i could just figure out a way to adjust the timing without an ECU tune on a coil pack system... i know adding resistors to the IAT did absolutely nothing to the timing although it showed the temp to be 180*F. i havent tried the ECT yet. Fuel is EASY to modify without an ECU tune.

Anywayys.. hydraulic drift brakes are amazing. HUGE difference between them and cable brakes.

[decipha]

what start up file would that be?

the only reason why your ecu doesnt have free support readily available is cuz no one has ever wanted it

hard to sell something thats free lol

[Stang95]

Will you release the file for us?

[decipha]

release what file?

[Stang95]

You know. The one so we can start our car .

[decipha]

as soon as a premium member wants it i'll make it, until then no

[Stang95]

Yup. like i said. $50 a pop for whoever wants it whenever i decide to buy it.

[Stang95]

From what i read you can dial in the car for $65 .

[decipha]

your not making any sense, how can u sell something thats free?

what do u mean dial in the car for $65?

i dont follow what your trying to say

[Stang95]

I bought a quarterhorse for $250 ...
There is no public file for my 3.8 v6 1995 ECU...
To get the file i must be a Premium Member which costs $450 minimum/must purchase a service..
Nope, not free.



"If your not going to be actively tuning it or logging after the fact you can sell the QH when we're done tuning her, they sell for $200 used so you can recoupe a few bucks. If you have a near stock setup I also offer a loaner QH as well, you pay a $250 deposit and I ship out one of my spare QHs. Then when we are done dialing her in you ship the QH back and I shoot u back the funds along with a chip to replace the QH for $65. If you decide you want to keep it which most do as I've never got a QH back before to date then no worries." <copy+paste to google. it'll bring you to the quoted page.

I was told and read over the years TunerPro had terrible support. Now i see why.
I now have some money to get tuned but i am questionable about "EFIdynotuning" and will take my money elsewhere.
Yes it costs a bit more but he seems like a joker and i do not trust him. Me and the other guys that have been wanting a tune for the past few weeks as well will be going elsewhere. Every other week i get an inquiry to where to get a tune. Missed your chance on some good business, dude. Shouldn't've been playing so damn much.

"the file's free, just ask"

*Well can i get the file?"

"what file"

"the startup file. so i can start the car at least. i will be selling it because it took so damn long to find it"

"only premium members can get it and it costs $450 minimum"

Well the file isnt free, now is it. Knowing damn well we could use a tuner.

[decipha]

tunerpro is free and support is open source thus tunerpro has only as much support as those willing

if u go back and read the third post youll see I was going to go above and beyond to take time out of my busy schedule to write you a custon free startup file and even take it a step further with a limited free xdf to dial in the maf, for no other reason than im such a nice guy

the reason i did not is because you replied back you only have 19lb injectors which i stated will not support your power, any real tune in there will just blow the engine, id rather not be involved at all with you damaging your car

I would prefer if you and your friends did take your business elsewhere. I prefer not to deal with people that get upset when someone offers to do them a favor for free out of the kindness of their heart and then get bashed for it.
