Engine Tech / ECU mystery box
Quote from: TOM Renzo;430057
If the ECM is not confirmed either by a factory number or a reman identification number BUYER BEWARE. This is why in most cases a stand alone system is normally your best bet or a known good and correct ECM NUMBER. Just me could be wrong. My ford guy says that ECM is a 4 banger i did not count the pins. How much did it cost you??? If it was cheap use it as a paper weight and chuck it up to experience.  By the way how do you know the ECM is GOOD. Even if it has the correct numbers and application the unit just might be a DUD??? Just a thought!! Never buy a pig in a poke. That is unless it was dirt cheap and you took a shot. Good luck!!
No need to lecture, this isn't my first car build and not my first mistake buying parts either. 

I paid $40 for it, which is at least $25 less than any ebay ECU for a 5.0, but also about $25 more than someone should pay for a 2.3L ECU.  I took the gamble and lost this time, but it's not bank breaking.

My buddy at a Ford dealer looked it up for me and he says it comes back to a 85-86 Mustang/Capri 2.3L non-turbo.


I believe that's the case.  Looking at the pinout, pins 12, 13, 14, and 15 should be connected to Injectors 3, 2, 5, and 6, and all of those pins are non existent on the computer's plugin.

Pin #1 is in the top right.

Here's the pinout diagram I used, it's for a MAF setup, but everything but the MAP/BAP should be the same I believe. 


Jangus,  I actually have his phone number, my friend grabbed it for me because of some injectors he would sell to me too.  Maybe I can get those in trade for the computer. (I'll make sure they're correct this time too).  If I can't get him on the phone for some reason, I'll send you a PM. 

Thanks everybody, I'll get it sorted out now that I know what I'm dealing with.

Engine Tech / ECU mystery box
I have a confusing situation here: 

My friend was at a swap meet and found a guy selling Mustang parts, so he grabbed an ECU for me from a guy that said it was from an '88 Mustang 5.0.  (I'm collecting parts for an HO swap).  He drops it off at my place, and we are completely dumfounded by the code on it.

It says TB over where the code should be, but that doesn't match up with any code on the Old Fuel Injection website.  The part number is E6ZF-12A650-B2A-MR, but is also noted as a REMAN.

The closest info I could find was a PN search on Rock Auto that showed the PN as an equivalent to an '85-'86 Mustang, Capri, LTD, Marquis, and E series.  That's a pretty wide range of models, and especially confusing because the 5.0 in the Mustang switched from carb or CFI in 85 to Speed Density in '86, and any smaller engines weren't shared with the full size cars and vans. 

So, help me out here.  What do I actually have or how could I figure it out?

Engine Tech / Explorer intake swap now or later?
No worries there, I got an HO upper with the throttle body from the previous owner, and I've been doing research on how to do it. 

One person said that the throttle shaft would swap right across, and other people say I'll have to grind off the cable mounting plate and put on the new one.  I'll find out for myself.

Engine Tech / Explorer intake swap now or later?
The people I've seen talking about it on a Grand Marquis website swore that anything under .500 lift at the valve should be fine with the SO pistons.  And from the cam stats I found, 1.7 ratio rockers puts me at .420 lift on the exhaust valve vs the .395 it currently is.  It should work for the HO cam too, it would increase the lift from .445 to .473.  Of course, I'd be smart to double check P/V clearance when installing the new heads and cam later on. 

It's a bit of a philosophy question about installing parts now or later.  Do you do the extra work to enjoy a small gain, or do you wait until you can do the entire job to get the large gain all at once? 

I'm more a fan of installing the parts I have even if I have to remove and reinstall them again later.  Yes, it's more work, but spending time in the garage is fun, and I have a bad tendency of giving up on a project if it gets too complex or if I see no gain in a long time.  Besides, with the intake and throttle body, there is a lot of work that will only need to be done once.  If I install the intake first, I won't have to worry about adapting the throttle body to fit on the Fox or making the EGR work or how the throttle cables will hook up because it will be done already.

Engine Tech / Explorer intake swap now or later?
I went back yesterday to try and get the heads too, but I was stumped by inaccessible bolts and cold weather, so I have no heads in possession yet. 

But I did work out a game plan for now. 

I'm going to adapt and install that Explorer intake and throttle body onto my stock E6 heads and SO cam.  I know I won't get that much of a boost, but I'd rather enjoy some extra power until I can collect all the other parts, even if it means a bit more work in the future. 

Also, while I'm at it, I think I'll find some 1.7 roller rockers to install too.  That'll give me some extra valve lift to go with my extra intake and exhaust flow. 

As far as I can research, that should let me run my 14lb injectors and stock ECU for now.  Then I can enjoy the extra 20hp or so while I'm gathering the heads, gaskets, cam, timing chain, ECU and other assorted necessary parts for a head swap. 

The only question left to research now is whether or not to keep the EGR.  I don't have emissions, but I've heard that it really helps with gas mileage.

I guess if I get really bored over the winter, I could give it a shot, but otherwise I'll just wait until I get all the parts.

Then again, I found this posted on a different forum about a 5.0 HO

Quote
A couple of years back I installed a Cobra intake on a friend's car that was stock except for a fenderwell cold air intake and a pair of welded in Flowmasters. It had been dynoed a month prior and turned 198hp to the rear wheels. After the swap, we took it to another dyno day at the same shop. This time it netted 220 to the rear wheels, but the power curve was much broader and it picked up as much as 28hp in the mid-range.

I kinda doubt it'd be that effective on a non-HO, but there seems to be quite a bit of gain just from the GT-40 style intake.

Well, I got some HO headers and a free flowing exhaust already, so no worries there. 

Heads and cam and ECU are planned upgrades, I just don't have the cash to buy them all right now.  I have a friend that has a truck engine he wants to part out, so I could get E7 heads for cheap to free, but he won't be doing that until summer at the earliest. 

In the end, I was more wondering if it'd be worth doing the intake swap for now, there'd be no being unhappy, just an intermediate upgrade before I'm finished.  If I only gained 5hp and a massive headache from the swap, it wouldn't be worth it.  But if I gained 20hp, it'd be worth the frustration until I can get the heads and cam and ECU and all the other

I was out at the junkyard today, and I found an explorer with the 5.0, so I took the intake off of it for my bird.  (I would have taken the heads too, but I ran out of time and didn't have the right tools). 

Anyways, I bought the intake, fuel injectors, fuel rail, EGR, throttle body, and MAF.  (I figured to get more than I need than not enough)

So...  my question is:  Is it worth swapping in that intake now or should I wait until I get some heads and a cam to swap in too?  I really don't mind removing and installing the intake twice, as long as I can enjoy some extra power until I can afford the rest. 

Then, if I did swap it now, should I keep the 14lb-hr injectors or would the computer compensate for the higher flow explorer injectors?  Would I have to worry about blocking off the internal EGR passages?

General Fox T-Bird/Cougar Discussion / New Springs!
I finally got around to doing an upgrade on my bird, and it feels good.  (Too much time spent getting the engine to run right and too much time spent worrying about money). 

Found some Mustang GT springs on craigslist that were only $40 and were used for only 6000 miles.  Then my friend came up this weekend to borrow my garage and my help, so I borrowed his help when we finished.  The result?

It looks good, it rides good, and it handles much, much better than it used to.  Granted, it's still stiff and jiggly because it badly needs new shocks (they're in the mail), but it was a huge improvement. 

The only thing I'm concerned about is how the front looks higher than the rear.  My friend swears that the springs will settle out over a few weeks and I won't have to worry about it, but a spacer could be easy to stick in under the rear springs.
