2.3 turbo swap
« on: August 14, 2012, 02:09:04 AM »
So I've been working on this swap for some time now.

This is what I've got going as far as parts
Turbo coupe stock fuel pump intank I made a mustang fuel
Pick fit the stock gas tank vent hole(at the top drives side)
I'm using the factor Hard lines from the pinto
with a 5.0 fuel filter. 3/8 high pressure rubber lines.
Stock fuel pressure regulator (fpr) and rail 35 lb inject
85 turbo coupe drive train
85 pc1 ecu also I stripped the car for the engine
Wiring harness  here is the sensor that I have found
Are actually in the wiring loom
Idle air control
Injectors
O2 sensor
Ignition to distributor and coil
Test plug (for codes)
Water temp /oil pressure
Needless to say I don't have the
Veichal speed sensor on the trans
Does anyone have info on the importance
Of this part and does it control the car under a load
Also can I just wire it straight the computer
I'm sure how much is need to make this swap work perfect
Please help me figure out why my car idles good but when
I drive it I can get it to barrelly putt around up to 3grand
Then it falls all over it's self  also the fuel pressure stays
At 80 psi
Any info would be the help full
whats up peps I own 73 runabout 2.3t swap, spd, pimp ecu, subframe connectors. Ive had this car for 10yrs and have done the work my self the car has been in my family for 30yrs. Alway looking for parts and I have a few my self too, please feel free to message me

Number one, the fuel pressure should not be 80psi and constant.  Suggest checking return line for blockage or maybe a stuck FPR.
 
If you did not get all the components from the same donor car, I would check the computer being calibrated for the injector size and VAM size used.  In your list of sensors used, I did not see the VAM, manifold pressure, throttle position.  The VSS is only used by the 87-88 computer, per literature.  Oil pressure is for the dash gauge and not engine control.  Make sure the engine temperature is the computer input and not the dash gauge (at least some use more than one engine temp sensor).  Probably missed some.  Have fun with the puzzle.

Here are some links that might help.  On this one, click on "EEC-IV" and then on "ECA's & chips".  It shows which VAM and injectors were used in different years.  Unfortunately the computer ID is not listed.
http://www.merkurencyclopedia.com/
 
This one shows the pin outs over various years.  A couple typos: add pin 56 for ignition PIP, add pin 57 to be in parallel with pin 37 V PWR.  Going upstream, the parent directory has a lot of info.
http://www.rothfam.com/svo/reference/ecc%20pins%20all.doc
These two are from the same general web site and show wiring.  The first one also shows where the sensors are located.
http://www.rothfam.com/svo/reference/85SVOevtm.pdf
http://www.rothfam.com/svo/reference/full%20diagrams/1985.pdf
 
These two may be helpful when trouble shooting.

The vam ,barrometric ,throttle position ,and injectors,computer
IAC,coil ,wiring harness ,engine for intake to oil pan
We're all takein from the same car. The car ran and drove
Before I striped the car I spent the time to make it run
Before I stripped the car. I bought the VAM new for the car
From a local auto parts store and drove it with it in stalled
Before I took the car apart. I feel that the fpr could be bad
But I also feel like  the wiring is causeing me the biggest
Problem. Almost like I don't have enough grounds  or something
Is not on the car. Iam going to buy a Kurban or bbk fpr that
Should help me fix the fuel pressure problem. I'll look closer to
The web sits stated I let you know what I find  thank you
All your help guys

Grounds can cause wierd stuff to happen, make sure the block to body ground is on and clean on both points,
You really only need to have 14 to 15 wires to make it work, and only 3 to connect to your Pinto harness, (switched power, constant power and a Ground wire)
Are you sure you have all the connections hooked up? Mine did wierd stuff at first and I found I never tightened up the 2 screws that secure the harness to the ECU
I'd start  here:.....   80 psi of fuel pressure is going to flood the engine.
Next look at all your wiring connections,
I've heard of peeps putting the VAM in backwords.

you ran the return line to the tank vent on the top driver side of the tank? did you drill out the inlet to the vent fitting? its just a tiny little hole inside the tube.... theres your pressure problem.....ju st pop it out and drill it out.... done in 10 minutes....

Probably ought to buy a fuel pressure tester.  This one is CHEAP, but ,if you get a good one (if not take it back for another - make sure it doesn't leak), it works well. http://www.harborfreight.com/fuel-injection-pump-tester-92699.html

You should be getting about 35-40 PSI.   Odd that it idles OK because high pressure would create an overly rich situation given that the injector pulse widths are likely near as low as they go.  Opening the throttle would seem to allow other sensors to somewhat compensate by recalculation of the readings.

As stated you need the fuel return!!!  I'm wondering what is happening at the fuel rail that the return hose isn't dangling and gushing fuel if you don't have one???  A bad fuel pressure regulator might be a problem too.

Nearly three years after I did the turbo swap (using the dreaded '88 harness) and I'm still having issues. Idles fine, decent power after 3K, but in the driving range of 2k-2.5k awful.  I pulled the Spout and it is better, but not right.  All the best.  Tom

Have you ever typed a really  nice reply to everone and it got ereased  well that just happened to me. but enough with that.
thank you for the ground info ill make some and install them.   Ill c if it makes a diference .  (it should)
As for the vent i drilled it out when i tryed to put the 255 walbro inline fuel pump in. But i didnt have a sump, so the car starved for fuel at idle in the driveway. I read about it some where,( probably on these forums) So i pulled all that out . Got 5.0 metal pick up and weilded a sump box to the bottom of it  small enough to fit the factory vent hole (On Pinto) and deep enough to hold fuel with the sock on it . Also trying to keep in mind that it had to touch the bottom of the tank.    I used a stock turbo coup pump and locked it all down with the 5.0 lock ring and it started to idle fine in the drive way.
 
I do need a fuel pressue tester ive got a cheap inline fpr with a gauge but whos to say that it is even accurate . but the gauge is read high and i can tell its over fueling the injector. i got locall H/F  here so ill go grab one .   R they  pretty well made?   
i  found a 85 xrt4 i today and it had a adjustable fuel damper . does ayone have one of these . If so do you like it, does it really adjust anything  or is it just for looks. I also grabed the harness. I read its the closes thing to a stand alone harness . do you think i should use it instead?
 thank you for the info ill keep  you poosted
