Engine performance matrix

Power, torque and fuel-economy figures for every tuning stage on this engine, sourced from the tuning-database Gains API. Values are healthy-engine crank numbers; real on-road gains vary with fuel, altitude and mechanical condition.

Fuel economy gain (vs. factory map, same driving profile): combined cycle −8% , full-load cruise −12%. Diesel calibrations typically net bigger combined-cycle savings thanks to shorter duty-cycle on low-load driving.

About this calibration file

This is the factory (original) ECU calibration for the 2002 Fiat Grande Punto 1.3L, extracted from a genuine stock control unit. Use it as a verified backup before flashing any performance tune, or as a reference when recovering an ECU from a failed write.

This file matches a Marelli ECU with hardware number 51796241. Verify both identifiers in your flashing tool before writing — an ID mismatch is the most common cause of a bricked ECU. If you are unsure, upload a read of your original file via the file-request wizard and our engineers will confirm compatibility before you flash.

The file is delivered as a ready-to-flash BIN (and ORI backup where applicable) compatible with all major tools — KESS V2/V3, KTAG, AutoTuner, CMDFlash, Dimsport New Genius, MPPS, Flex, BFlash, PCMFlash, MMFlash — via OBD, bench or boot-mode as supported by your ECU family. Checksums are pre-computed and verified; no additional checksum tool is required. All files include a free revision if post-flash logs reveal a fuelling, boost or EGT issue.

Frequently asked questions

The file is written for the exact ECU hardware 51796241 (Marelli) listed in the specifications. Read your ECU with any supported tool (KESS, KTAG, AutoTuner, CMD, etc.) and compare the hardware + software numbers against the ones on this page. If they match exactly, the file is a direct fit. If you're not 100% sure, upload your original read via the file-request wizard and our engineers will confirm within minutes — no cost, no obligation.

Two reasons. First, if your ECU write failed mid-flash and you need a verified stock image to recover from — this file restores the unit to the exact calibration it left the factory with. Second, if you plan to experiment with a tune and want a known-good rollback point that is guaranteed identical to a Fiat dealer programming.

Instant. Immediately after payment clears (typically < 30 seconds on Stripe / PayPal), the download link appears in your account dashboard and is also emailed to you. The link is a signed, expiring URL — download it within 24 hours; if it expires, just re-generate from the dashboard at any time.

Pre-corrected. Every tuning file we sell is processed through CHKSuite (our in-house checksum engine) before it reaches your download link. You can flash it directly with KESS, KTAG, AutoTuner, CMD, Dimsport or any other supported tool — no extra checksum step required. A zero-CRC write to a modern Bosch/Siemens/Delphi ECU bricks the unit, so this is non-negotiable.

Contact us on WhatsApp or through the dashboard support thread. Free revisions are included for the same stage on the same ECU — send us a live log (via VCDS, INPA, EcuConnect, OBDeleven or similar) and we'll adjust timing, boost, rail pressure or smoke limits and re-issue the file. A failed flash itself (write aborted, bricked ECU) is recoverable with our Original file and a bench tool.

This product contains a complete original ECU backup (stock file) for Fiat Grande Punto 1.3 Multijet 2002 51.5KW with Marelli 51796241. This original file corresponds to a factory engine output of approximately 51.5 kW (~70 HP). This file is ideal for ECU cloning, restoring the car back to stock and using it as a safe base for future remaps.

All ECU tuning files from TUNING-DATABASE are prepared for professional use. They are useful whenever you search by ECU ID, hardware or software number such as 51796241. Use this file for diagnostics, cloning, recovery or as a base for custom remapping.
