Operations performed 3

  1. STAGE1 automated · solution rev 1 · ~15 min

    A safe performance tune that needs no mechanical changes and does not harm the vehicle.

  2. DECAT automated · solution rev 1 · ~5 min

    Disables catalytic converter efficiency monitoring and the P0420/P0430 fault codes.

  3. POPBANG automated · solution rev 1 · ~15 min

    Creates exhaust pop & bang / crackle sounds; requires a decatted exhaust with few silencers.

Other solutions for this ECU 6

Every operation below can be ordered for the same DENSO PETROL file (petrol). Prices are per file in EUR; automatic solutions are delivered within minutes, engineer-assisted ones are prepared by our tuning team.

STAGE1 A safe performance tune that needs no mechanical changes and does not harm the vehicle. done in this project ✓
STAGE2 A performance tune that requires hardware changes such as exhaust, filter or DPF removal. engineer-assisted, on request · ~60 min 160 EUR
STAGE3 A performance tune built from data logs after vehicle-specific hardware upgrades. engineer-assisted, on request · ~180 min 800 EUR
LAMBDA OFF Disables the oxygen (lambda) sensors. engineer-assisted, on request · ~5 min 20 EUR
DECAT Disables catalytic converter efficiency monitoring and the P0420/P0430 fault codes. done in this project ✓
VMAX OFF Removes the speed limiter (Vmax) or sets it to the desired value. engineer-assisted, on request · ~5 min 20 EUR
POPBANG Creates exhaust pop & bang / crackle sounds; requires a decatted exhaust with few silencers. done in this project ✓
POPBANG SWITCH Lets you turn the pop & bang feature on or off via a button or mode; may not suit every vehicle. engineer-assisted, on request · ~60 min 400 EUR
DTC OFF Permanently disables the fault codes (DTC) you select; you need to provide the P codes to turn off. engineer-assisted, on request · ~10 min 40 EUR

About this project

Denso ECUs are used by Toyota, Mazda, Subaru, Suzuki, Opel and other Japanese-engine vehicles. This unit is fitted to SUBARU Car vehicles. Project #4907 was completed automatically by the ECUHARD file service for a SUBARU Car vehicle.

Frequently asked questions

What was done to this DENSO PETROL file?

Operations performed: STAGE1, DECAT, POPBANG. The modified file was checksum-corrected and delivered ready to flash.

What is the software version for this DENSO PETROL file?

This project is for DENSO PETROL with software numbers: . The same operations apply to other vehicles running the same software.

Can I get the same tuning for my SUBARU?

Yes. Sign in, upload your original ECU file (DENSO PETROL or any supported ECU), choose the operations you need and our automated system prepares the file, usually within minutes, 24/7.

I read my ECU with a different tool — will the tuning fit my file?

Yes. Every operation is applied to the file you upload — your own read from your own car — so the tool and the read mode do not matter: the modifications are located by content, not by a fixed file layout. If your file was modified before, our REV ORI (revert to original) module repairs every changed area back to the stock values first — no matter which tool or method read it (KTAG, KESS, Flex, Autotuner, CMD, OBD, bench or boot). A compatibility problem is therefore impossible.

I have an OBD read — can you tune it, or do I need a bench/boot read?

An OBD read is fine as long as it contains the software area (maps). Upload it; the platform detects the ECU and software number and shows which operations are available for your file. If the read is partial and an operation is not possible on it, you will see that before paying.

I read boot mode with KTAG / bench with Flex / bench or OBD with Autotuner — which read do I upload?

Any of them. Upload the file exactly as your tool saved it (DENSO PETROL reads are supported in OBD, bench and boot form). The system works on your own read, so nothing has to be converted or matched to a different device.

Do you need the full backup (EEPROM, other sectors)?

No. Only the software-related part of the ECU is used: the maps area — the internal flash and/or the external flash, depending on where the software lives in that ECU. EEPROM and other memory sectors are not needed and are never modified. Keep your full backup for yourself as a safety copy.

How can I be sure the result will be compatible with my ECU?

Because the file returned to you is your own read with only the selected areas changed and the checksum corrected, it flashes back with the same tool and method you used to read it. The software number stays the same; nothing else in the file is touched.

What other operations are available for DENSO PETROL?

STAGE2 (160 EUR, engineer-assisted, on request); STAGE3 (800 EUR, engineer-assisted, on request); LAMBDA OFF (20 EUR, engineer-assisted, on request); VMAX OFF (20 EUR, engineer-assisted, on request); POPBANG SWITCH (400 EUR, engineer-assisted, on request); DTC OFF (40 EUR, engineer-assisted, on request). Prices are per file.

I have a DENSO PETROL file — how can I get it done?

Sign in to the ECUHARD platform (solutions.ecuhard.com), upload your ECU file, select the operations you need and confirm. Automatic solutions are delivered within minutes, 24/7; engineer-assisted operations are prepared by our tuning team. Each file is checksum-corrected and an invoice is issued automatically.

Do I need to send my original file?

Yes — upload the stock read of your ECU. If you do not have it, our original file archive may have a matching file by software number.
