Injector Dynamics ID1750-XDS Fuel Injectors for Cadillac CTS-V 2009-2014 and GM LS Engines - Set of 8

Injector Dynamics ID1750-XDS Injectors for the 2009-2014 Cadillac CTS-V and GM LS Engine Family

The supplier title this listing was imported with read Cadillac CST-V, which is not a car. The correct name is CTS-V, and Injector Dynamics lists 1750.34.14.15.8 against the CTS-V 09-14 row of its application table, not against an open-ended 2009 and later range. Both errors have been corrected here.

The same part number covers a broad slice of the GM LS world: the LS3, LS7, L76, L92 and L99 engine listings, the Camaro 10-15 and Camaro ZL1, the C6 Corvette including Z06 and ZR1, the Holden Commodore W427 and E-HSV, and the Pontiac G8 GT and GXP. What ties them together is the lower interface. This is the 15 mm lower O-ring configuration, which is what separates it from the otherwise similar 34 mm sets that use a 14 mm lower.

Key Features

• The 15 mm lower O-ring configuration Injector Dynamics lists for the Cadillac CTS-V 09-14 and the GM LS engine family
• Matched set of eight, consistent with the manufacturer's published per-set pricing for this number
• Covers the Camaro 10-15 and ZL1, C6 Corvette, Z06 and ZR1, Holden Commodore W427 and E-HSV, and Pontiac G8 GT and GXP rows
• Distinct from the 14 mm lower configuration used by other 34 mm ID1750-XDS sets, so the lower O-ring size decides which number an LS engine takes
• Rated at 1728 cc/min at 3.0 bar (43.5 psi) on E10 emissions certification fuel, with a published maximum differential fuel pressure of 7.0 bar
• Compatible with methanol, ethanol, MTBE, nitromethane and all known hydrocarbon fuels, with a USCAR electrical connector
• Published dynamic flow and offset data from 8 to 16 volts across the working pressure range, for direct entry into an engine management system

Fitment

The Cadillac row is published as CTS-V 09-14 with the supercharged 6.2-litre LSA engine. That displacement belongs in this description and in the specifications, not in a fitment tag, and the same rule removes the LS3, LS7, L76, L92, L99 and LS9 engine codes from tagging. The Camaro row is published as 10-15 without a trim, so the tag stays at the model level and the ZL1 row, which has no published years, is documented here instead.

Specifications

What's Included

• Eight Injector Dynamics ID1750-XDS fuel injectors in the 1750.34.14.15.8 configuration, supplied as one dynamically matched set.
• Because the manufacturer publishes specifications and applications but no packing list, nothing beyond the injectors themselves should be assumed to be in the carton.
• Tuning data is not a physical item in the package. Injector Dynamics distributes offset and slope values digitally and continues to refine them.

About Injector Dynamics

Injector Dynamics describes the X-Series as designed specifically for motorsport use, and the ID1750-XDS is the large-capacity member of that family. Its part numbering is deliberately granular so that body length, top interface and lower interface are fixed by the number rather than left to the installer.

FAQ

1728 cc/min at 3.0 bar (43.5 psi), which is the figure Injector Dynamics publishes for the whole ID1750-XDS family.

Only up to the published maximum differential fuel pressure of 7.0 bar (101.5 psi).

The manufacturer lists methanol and ethanol among the compatible fuels, and describes corrosion resistance as compatible with everything but dirt.

Only where the vehicle already uses a USCAR connector. Otherwise an adapter or a re-terminated loom is needed, because the injector is specified as USCAR.

Because the manufacturer matches them as a group, and its service department asks for the complete set when work is needed.

Yes, one year from original purchase for manufacturer defects, per the manufacturer's published terms.

By the four to seven digit serial number at the base of the connector, which the manufacturer uses to process the set.

No. The published offset and slope tables for the ID1750-XDS have to be entered before the engine is started.

No road-use or emissions-compliance claim is published for it. The manufacturer describes the X-Series as motorsport equipment.

Injector Dynamics publishes CTS-V 09-14 against this part number. Model years outside that range are not supported by the manufacturer table.

Yes. It read CST-V and claimed 2009 and later coverage. The correct designation is CTS-V and the published range ends at 2014.

The supercharged 6.2-litre LSA is the engine in the listed CTS-V and Camaro ZL1. Displacement is never placed in a fitment tag because the storefront searches by year, make and model, so it lives in the copy and the specifications instead.

The lower interface. This configuration uses a 15 mm lower O-ring, where the otherwise similar 34 mm sets use 14 mm. They are not interchangeable.

Not under this number on the ID1750-XDS table. The C5, including Z06, is listed against a different configuration, so check the exact row before ordering.

Yes, the Commodore W427, Commodore E-HSV, G8 GT and G8 GXP rows all point at this number, though no model years are published for them.

Installation Instructions

No installation document is published against this number. The steps below cover only the manufacturer's documented cautions, then defer to the factory service information for the engine at every point where a torque value or a removal sequence is needed.

1. Confirm that part number 1750.34.14.15.8 is the configuration Injector Dynamics lists for the 2009-2014 Cadillac CTS-V and the GM LS applications listed alongside it before anything is removed from the engine.
2. Note the serial numbers stamped at the base of each connector so the set can be identified if it ever goes back for cleaning and inspection.
3. Bleed off fuel pressure before anything is disturbed, then follow the factory service information to free the fuel rail.
4. The molded O-ring retainer stays in place unless Injector Dynamics has specifically confirmed the application needs it removed.
5. Check that the injector seats fully in the rail and in the port with the 34 mm and its listed interfaces before committing to the install.
6. For connector assembly, remove roughly 5 mm of insulation, pass the wire through the seal into the terminal, check the bare wire sits in the crimp section and crimp the terminal.
7. Polarity is not a consideration at the injector plug according to the manufacturer's own connector guidance.
8. Use factory service torque values throughout. Inventing a figure because the injector manufacturer publishes none is not acceptable on a fuel system.
9. Configure the tuning platform with freshly downloaded ID1750-XDS characterization data before the engine is run.
10. Bring the system up to pressure with the engine off, look carefully at every seal, and satisfy yourself that filtration is adequate before starting.
