We are referring to the 87-95 GM TBI-Throttle body injection systems.
The ECM will be 88-91
I prefer a throttle body after 91 with the round TPS.

There is a nationwide junkyard search website call www.car-part.com
You can enter the vehicle, chose the part and SORT by PRICE.
Then you will a list of that part.
Scroll down to the bottom and find the page number with the asterisk ie 13 14* 15.
That will be the page with the lowest price page.
There's also EBay. Be very careful there.

The primary system being from a truck, van, or astro van with 4.3 or larger engines and using the 1227747 ECM. Pick the ECM used with the same number of cylinders as your project. 4 cyl guys will just have to use the V6 ECM. If you do get the 4.3 V-6 ECM for your V8, you will need to replace both chips in it with the V-8 chips.
If you need to look up which bin you have, see the Broadcast code(BCC) look up file attached below.
The V8 limphome/netres chip/Calpack is marked 16060837. Order part number 16060836.
The V6 netres part number is 16051637.
The number on the chip that I had is 1 number different due to it being sold in the plastic carrier!!!

GM PART # 16060836
CATEGORY: Emission Control System Hardware
PACK QTY: 1 CORE CHARGE: $0.00
GM LIST: $21.07
OUR PRICE: $10.54
DESCRIPTION: CALIBRATI

You may find some 87's and some 92's with the same system so look close.
As a secondary you can use the 1228746 computer from the cars but will require an IAT sensor and a different chip than the 7747.
If you are pulling the system yourself then pull everything off the motor that the harness is attached to! You can throw the unneeded parts away later.

MY HFI-DIY KIT INCLUDES A NEW STAND-ALONE HARNESS, ADAPTER PLATE, CUSTOM TUNING AND DISTRIBUTOR TO MAKE THE CONVERSION EASIER OR CHEAPER THAN A COMPLETE JUNKYARD OR NEW SYSTEM.

Basic system:
1. Computer- better known as the ECM-engine control module. 1227747 You will need someone to program a chip for you to optimize the computer to your engine.
IF YOU DON'T KNOW WHAT ENGINE YOUR COMPUTER CAME FROM, SEE THE ATTACHED FILE BELOW.
You will need the 3 or 4 letter BCC-broad cast code.
If you buy an ECM from a parts store, it will NOT have the chips you need in it.
I recommend a used pull since the ECM rarely goes bad.



15341227747_ecm.jpg


2. Throttle body- TB- The 2.8l with 1 3/8 bore is ~240CFM, the 4.3, 5.0 and 5.7 TB's are all the same ~500 CFM with 1 11/16" bores. The injectors are different sizes.
The 454 is larger with 2" bores and near 700CFM.
I would recommend a TB from about the same size engine or larger. 304/345 use 5.0/5.7. If you run a cam/springs and headers then maybe the 454 TB. 392 can use the 350 or 454 TB.
Our motors turn so slow that you can actually tune a 345 to the 305 system.

If you perform the adjustable regulator mod further down in the FAQs, you can bump the fuel pressure on the stock regulator to about 15psi. Maybe 16 if your lucky. To see what that means see each injector size listed.
These are all based on 12psi. The big question is, what pressure is your system operating at?

Injector sizes-
Color code Black/White
Engine 2.8L
Flow 33 lbs/hr @ 12psi
37lb/hr @ 15psi
TBI bore 35mm
GM part # 5235130

Color code Yellow/Blue
Engine 4.3L
Flow 45 lbs/hr @ 12psi
50@15psi
71@30psi(near late model 454)
TBI bore 43mm
GM part # 5235203

Color code Green/White
Engine 5.0L
Flow 50 lbs/hr @ 12psi
56@15psi
TBI bore 43mm
GM part # 5235279

Color code Orange/Black
Engine 5.7L PU
Flow 61 lbs/hr @ 12psi
68lb/hr at 15psi
TBI bore 43mm
GM part # 5235206

Color code Yellow/Brown
Engine 5.7L CopCar
Flow 65 lbs/hr @ 12psi
72.6@15psi
TBI bore 43mm
GM part # 17084327

Color code Lt Blue/Black
Engine Late BB PU
Flow 76 lbs/hr @ 12psi
85@15psi
TBI bore 51mm
GM part # 17084304

Color code D Red/D Blue
Engine Early BB PU
Flow 80 lbs/hr @ 12psi
90@15psi
TBI bore 51mm
GM part # 5235231

94-95 454
Pink/Purple
45(actually 48)lb/hr @ 12psi
76lb/hr @ 30psi
17104288

Which means you can take the more common 4.3 or 5.0 injector and increase the pressure to 28-30psi (new spring) and do the same thing as the factory for 454 injectors.

1 barrel TBI injectors.....and were used on the early Holley 2 barrel replacement TBI's.

3. Wire harness-pull from any donor vehicle above. It will need to be modified to fit your application.
1534wiring_harness.jpg



4. Temp sender-CTS pull from donor or buy new.

1534CTS.jpg


Coolant sensor approximate resistance specifications:
177 ohms @ 212 deg. F. or 100 deg. C.
241 ohms @ 194 deg. F. or 90 deg. C.
332 ohms @ 176 deg. F. or 80 deg. C.
467 ohms @ 158 deg. F. or 70 deg. C.
667 ohms @ 140 deg. F. or 60 deg. C.
973 ohms @ 122 deg. F. or 50 deg. C.
1188 ohms @ 113 deg. F. or45 deg. C.
1459 ohms @ 104 deg. F. or 40 deg. C.
1802 ohms @ 95 deg. F. or 35 deg. C.
2238 ohms @ 86 deg. F. or 30 deg. C.

52700 ohms @ -22 deg. F. or -30 deg. C.
100700 ohms @ -40 deg. F. or - 40 deg. C.

5. O2-oxygen sensor- You could pull from donor but a new one is cheap. 1 wire sensor will work fine. The universals just splice onto the wire from the harness.
For headers I recommend a 3 or 4 wire sensor. They have a built in heater to keep the sensor hot when it is mounted down in the collector.

15341_wire_O2_sensor.jpg

15344_wire_O2_sensor.jpg

1534O2sensor.gif


To mount the O2 sensor you can buy the regular O2 Bung or it they are not avail I use the 18mm sparkplug antifouler cut in half.

Summit racing
SUM-G2990 $4.88

sum-g2990_m.jpg


Motormite Spark Plug Non-Fouler: HELP!®; 18mm Gasket Seat; 2 Per Package 42009

1534antifouler42009.jpg


6. fuel pump- You have a choice to modify your tank for an in tank pump or mount one external to the tank.
For inline there are many choices. E2000, E2182 and some universals E8228/E8120/E8248/E8445/Walbro GSL-392. See Below.............

Here's some of the specs.
Note as pressure drops so does fuel volume
We run the TBI at 11-13psi and the MPFI at 40-50psi.
Also note there are several different fittings involved from ford quick disconnect, 5/16 barb and 3/8 barb.

E2000- 100psi/40gph -45psi/25gph
E8845- 30psi/55gph
E8228- 125psi/38gph
E8445- 55psi/35gph
E8248- 120psi/70gph
E8094-17psi/50gph

I used to run the Masters E2182 from AZ. $75 and I always run a Fram G-3 filter before the pump.
But the 89 Ford E2000 is only about $25 on ebay now. Use the Dorman 800-119 fittings to make it a 3/8" quick disconnect.
Makes changing a fuel pump an easy 5min job.

If looking for a higher flow rate for performance applications you can look at the Walbro GSL-392 at gsl392.com for about $100. Their price has come down with all the other universals on the market. The E2000 works fine for a stock application and more is not always better so match the pump to your application.
Hit ebay, amazon, rockauto or summitracing and compare.

Here is the 1989 ford F250 frame pump. E2000
1534Masters_E2000.jpg


1989 FORD F-250 PICKUP
L6 4.9 Liter FI - 300 CID VIN Y O.H.V.
V8 7.5 Liter FI - 460 CID VIN G O.H.V.

V8 5.0 Liter FI - 302 CID VIN N O.H.V.
V8 5.8 Liter FI - 351 CID VIN H O.H.V.

V8 5.8 Liter FI - 351 CID VIN H O.H.V.
V8 7.5 Liter FI - 460 CID VIN G O.H.V.


Looks like Master has finally came up with a universal kit. It's the same pump with standard barb fittings. It'll work fine but looks like it cost a little more since it has the mounting ubolts.

Price:$127.99

Part Number: E8248
Weight: 1.8 lbs
Warranty: 1 YR
Contents: 2 hex nuts, 2 lock washers, o-ring, hose clamp, screw with lock washer, mounting bracket, vinyl cap, terminal

7. Fuel pump relay- Part of HFI harness-From donor vehicle with the harness. Or you can use an additional bosch relay.

1534Fuel_Pump_relay.jpg


8. Pwr relay- Part of HFI harness. I use the small 30amp bosch style aux lighting relays from AZ about $4 I think they are called Baja's.
1534Bosch_relay.jpg


9. Adapter plate for the TB- you can make one or buy one.
Keep in mind that all holley adapters are for the larger 454 throttlebody and should not be used with the standard throttlebody or vacuum leaks can occur.
Due to the adapters that were avail, I decided to have some of the more common ones produced at a CNC machine shop.

You can click here to see a complete list of the products I now offer.

Adapter_1_640x480_.jpg


Adapter_15_640x480_.jpg


Spreadbore 4V- Holley


For more options Click here.

10. Distributor/EST-electronic spark timing- Also know as the ICM-Ignition control module. For FI you will need to decide if you want a complete conversion (fuel and timing) or partial (fuel only).
I only do fuel and timing control as designed by the factory.
For fuel and timing you will need a distr with a magnetic pick up. You have 2 choices.
A. The duraspark or Mopar conversion. Distr conversion has the EST mounted external on an alum metal heat sink.
I use a 6" x 1 1/4" x 1/8" aluminum strip that I drill and tap for 6x32 stainless screws to fasten the module to.
I also drill holes for the small locating buttons on the bottom of the module.
I fasten the module to one end and then drill a 5/16 hole in the other and attach under the coil mounting bolt.

B. My new EFI distributor
For the fuel only conversion you will retain your stock distributor but will need a special filter to run between your ignition and the computer.

EST

11. MAP-manifold absolute pressure sensor- this senses the change in manifold pressure. it usually is mounted on a plate, bolted to the intake manifold. You can modify the plate and remount it on the IH manifold or make a plate and mount it on the firewall.

1534Map_sensor.jpg


A 1 BAR MAP sensor reports barometric pressure times one, which is approximately 14.7 psi or 30in/Hg (inches of mercury). As an example, a typical three wire MAP sensor has 5 volts and ground to power the circuit. The signal circuit, or return voltage to the computer, is about 4.5 volts at barometric pressure of 14.7 psi; this measurement is taken at key on engine off. The sensor can withstand about 1.5 BAR of pressure, but the return voltage will peak out at about 4.8 volts. This type of sensor is designed for a normally aspirated engine to read a negative pressure, or vacuum, at a typical barometric pressure.

Testing

This is the voltage to pressure table for a standard 1-bar MAP...
Volts, kPa
0.00, 00
0.30, 10
0.60, 20
1.10, 30 (approx 20 Inch mercury vacuum)
1.70, 40
2.70, 50
3.30, 60
3.80, 70 (approx 10 Inch mercury vacuum)
4.40, 80,
4.90, 100 (no vacuum; full atmosphere)


12. If using the 1228746 ECM you will also need the IAT. Inlet air temp sensor off the air cleaner.
1534IAT.jpg


Options: Programming chip may be required to prevent SES light if not used.
1. Knock sensor- Screws into the side of the engine in front of the starter. It screws into the water drain plug hole. Get from donor.
If you are not going to program the chip then I recommend you run the knock and ESC.
1534Knock_sensor.jpg


Here's a short list of knock sensors and ESC's

ESC Module(GM #)..Knock Sensor(GM #) ..Known Applications

16052391 .............10456287 .................5.0L V8
16052401 .............10456288 .................5.7L V8
16128261 .............10456288 .................5.7L V8
16065711 .............10456288 .................4.3L V6, 5.7L V8
16128251 .............10456288 .................4.3L V6, 5.7L V8
16131171 .............10456288 .................7.4L V8



2. Knock control- ESC-electronic spark control. this sends the signal from the Knock sensor to the ECM to reduce the timing if it hears a ping.
1534ESC.jpg



3. Vehicle Speed sensor- VSS sends the ECM the cars speed. Jags that Run (JTR) sell an aftermarket VSS that screws right onto the transfercase between it and the speedometer cable. Good for smooth decelleration and also for cruise control input on later systems. (I now carry these in stock, see the machine shop forum)
More options
1. The two-pulse square unit for all passenger car TBI installations, all computer controlled carbureted engines, and 1985–1989 TPI engines. 7/8-18 thread, .104" square drive.
1534SpeedSensors.gif


4. EGR-exhaust gas recirculation solenoid- If you need to run emissions on your scout.
1534EGR_solenoid.jpg


Recommended coils to use.
First would be the stock TBI Epoxy core coil.

Then I would say the Ford TFI coil. It's supposed to have a hotter spark than the GM coil.

To look up replacement parts go to www.partsamerica.com or www.rockauto.com and use an 88-91 chevy 1500 with a 350 automatic.

Fuel pump try an 89 ford f250.

Or for used parts your options are www.EBay.com I use a guy named Steve for sets of sensors or parts I don't want to pull myself. His EBay username is ragged and he has his own ebay store now.

or for a complete junkyard network on the web.
www.car-parts.com
use the same vehicle for look up.
