Information on GM Fuel Injectors

The table below shows GM fuel injector color codes, engine size, part numbers, and flow rates. If the flow rate says stock, it was derived from the binary file that was associated with that injector. In other words, this is the stock flow rate that was programmed into the chip. This flow rate is accurate at around 10 PSI. If the flow rate is indicated at a certain pressure, this is the flow rate that I measured at the indicated pressure. If I have a binary file and associated injectors, I will always post the stock value here because it is the most accurate. Otherwise, I will post a measured flow rate. My manual goes into detail about how to calculate the flow rate at pressures other than stock. Do not use the injector flow rate table on www.diy-efi.org. It is not accurate.

Color code Application Flow rate Part #
Black/White 2.8L GM 5235130 *RPD 35.4#/hr @ 10 PSI
Yellow/Blue 4.3L GM 5235203 *RPD 45.9 #/hr stock
Purple/Brown 4.3L GM5235342*RPD 58.2 #/hr @ 17 PSI
Orange/Green 4.3L GM5235134*RPD 55.9 #/hr @ 15 PSI
Green/White 5.0L GM 5235279 *RPD 54.1 #/hr stock
Orange/Black 5.7L GM 5235206 *RPD 61.2#/hr stock
White/Brown 5.7L Cop Car GM 17084327 68.3 #/hr stock
Blue/Black Late big block pickup GM 1708430 *RPD 80 lb/hr stock
Dark Red/Dark Blue big block pickup GM 5235231 *RPD 90 lb/hr stock
??/?? 4.1L GM5235048*RPD 57.1 #/hr @ 16 PSI
??/?? 5.0L? GM5234395*RPD 54.1 #/hr stock
??/?? 5.0L? GM5233785*RPD 65.1 #/hr @ 15 PSI

The last two injectors are from single barrel TBIs on 2.5L S-10 trucks. They flow the same as a 5.0L TBI with twin injectors. So you can use two of the single barrel injectors in a twin TBI and get the same power as the 5.0 TBI.

A quick explanation of how to tune a TBI chip for fuel is as follows:
1) get your injector part # and find the flow rate from this table. If using my pump, calculate the flow rate at 12 PSI since that is about what my pump makes on a stock regulator.
2) Use your engine size and the flow rate to calculate the Base Pulse Width constant and program it in the chip. Once you start tuning, leave the BPW constant alone unless you want to start tuning over again after changing it.
3) Turn off EGR in the chip, and use WINALDL to collect BLM data from your system.
4) Adjust the VE tables in the chip using the procedures described in the VE table section of my DIY manual.
5) Repeat step 4 until almost all of your BLM values are in the 125-128 range.
Spark table tuning will be covered in another setion.
