Chip tuning for Chrysler 300C 6.4 V8 SRT8 477 hp ECU

Chrysler 300C (2015 - LD-FL) 6.4 V8 SRT8 477 hp — mass-market petrol engine of the passenger segment of the Stellantis group (США, 1925). Stage 1 chip tuning raises power from 477 to 500 hp (+23 hp, +5%) and torque from 637 to 668 Nm (+31 Nm). This engine ships with different ECU variants: Siemens/Continental GPEC2, Siemens/Continental GPEC2A. The flashing method is determined by the specific unit: OBD, Bench or Boot mode. The ZF 8HP70 TCU is calibrated with a separate file — torque limiter and shift maps for Stage 1. In the CHIPOK database: 3 configurations · 3 ECU variants. The 2015 generation — mid-generation petrol ECUs (MEDC17/MEVD17/Simos PCR), OBD flash on production revisions.

Chrysler is an American carmaker, founded in 1925 by Walter Chrysler. Chrysler currently builds mainly minivans and the 300 saloon. Chrysler shares platforms and engines with Dodge, Jeep and Ram. The Chrysler petrol range is mainly the Pentastar V6. The Hemi V8 is the proprietary Chrysler/Dodge engine for the top models. The top Hemi Hellcat offers significant potential with hardware.

HP Tuners is the leading tool for Chrysler/Dodge. The Hellcat confidently reaches Stage 2 with hardware. The US Chrysler community has a large pool of ready-made Stage files. Top Chrysler/Dodge Hellcat engines sit at the power ceiling of the American mass market.

Chrysler uses the ZF 8HP on its top models. The TCU rarely needs recalibration up to Stage 1+. Hellcat models use a reinforced ZF 8HP.

How much horsepower does Stage 1 add for the Chrysler 300C 6.4 V8 SRT8 477 hp?

The Stage 1 gain for the Chrysler 300C 6.4 V8 SRT8 477 hp is 23 hp (+5%) over the stock 477 hp, for a total of 500 hp. Torque rises from 637 to 668 Nm (+31 Nm).

What is Stage 1 chip tuning for the Chrysler 300C?

Stage 1 on the Chrysler 300C 6.4 V8 SRT8 477 hp is a software ECU calibration with no hardware changes. The key maps (boost/ignition/lambda/torque) are adjusted while factory tolerances are preserved. The gain is +23 hp with no hardware changes.

What does Stage 1 give on the top-spec Chrysler 300C 6.4 V8 SRT8 477 hp?

Stage 1 for the Chrysler 300C 6.4 V8 SRT8 477 hp unlocks the potential built in by the factory but artificially capped to meet mass-market targets. A base of 750-800 hp is achievable once hardware is added.

How does Stage 2 differ from Stage 1 on the Chrysler 300C 6.4 V8 SRT8 477 hp?

Stage 2 on the Chrysler 300C 6.4 V8 SRT8 477 hp means software + hardware (exhaust, intake, intercooler). The gain depends on the specific hardware combination.

How many ECU variants does the Chrysler 300C 6.4 V8 SRT8 477 hp have?

The Chrysler 300C 6.4 V8 SRT8 477 hp has 2 ECU variants: Siemens/Continental GPEC2, Siemens/Continental GPEC2A. Before flashing you need to read the specific unit — calibration is done for the exact hardware/software.

Does the ZF 8HP70 transmission need calibration after Stage 1 on the Chrysler 300C?

Remapping the ZF 8HP70 gearbox is essential to fully unlock Stage 1 on the Chrysler 300C 6.4 V8 SRT8 477 hp. Without a TCU update the factory torque cap will choke the torque gain and shifts will become noticeably softer.

Does Stage 1 void the warranty on the Chrysler 300C?

Stage 1 on the Chrysler 300C voids the factory warranty on the engine and transmission — this is standard for all manufacturers. CHIPOK provides its own warranty on the quality of the remap.

How quickly is chip tuning of the Chrysler 300C 6.4 V8 SRT8 477 hp done?

The full remap cycle for the Chrysler 300C — from reading to writing the final file — takes 30-90 minutes depending on the ECU access method. The file is prepared at CHIPOK in 5-30 minutes.

Can you return to stock after Stage 1 on the Chrysler 300C?

The original Chrysler 300C ECU is always saved before flashing. Rolling back to the factory firmware is done with the same programmer in 25-30 minutes.

How much does Stage 1 cost for the Chrysler 300C 6.4 V8 SRT8 477 hp?

The cost of Stage 1 for the Chrysler 300C 6.4 V8 SRT8 477 hp is calculated in the calculator on this page — you select the options (DPF off, EGR off, AdBlue off, DTC off, etc.) and the price is capped by the package Max Price. Payment is by credits (1 cr = 1 €), with no subscriptions.
