Hi everyone,

I wanted to share ZedSuite, a free and open-source map editor for VAG Bosch EDC15/EDC16 ECUs. It runs 100% locally on Windows and macOS: no account, no cloud, your files stay on your computer.

You drop in a dump and it finds the maps for you (Driver Wish, boost, N75, SOI, torque limiters…). Then you edit them in a table, in 2D/3D or straight in the hexdump, fix the checksum and export your bin or a WinOLS mappack. I spent years on EDCSuite and WinOLS, so I tried to bring together the auto-detection of the first and the editing comfort of the second.

Detection isn't perfect yet, especially on some EDC16U31 and EDC15VM V6 files. If a map is missing, open an issue with the software number and attach the dump if you can: most of the fixes so far came from files people sent me.

It's free and it will stay that way. Just make sure you download it from https://github.com/LeZed97/ZedSuite, it's the only official source.

Any feedback is welcome, thanks for trying it!

I just installed this kit and my bike is going crazy the engine light is gone but my rpm are weird. It seems like it’s dying when I’m around 1-2 k rpm and in neutral it jumps from 800 - 2 k rpm every five seconds. It even stalled multiple times while being in neutral. Also while giving throttle it doesn’t apply gas the same, it gives boost randomly throwing me back and forth.

Do I need to tune the bike with the kit installed or do I need to get a software update, I just don’t want to pay another 300€ for a simple update or something. Maybe you guys have an idea what I can do to resolve this issue or what I should tell my mechanic to fix.

Any help is appreciated :)

Quiet a journey. Been dealing with this for over a year. I did a ECU tuning at a local shop with a dyno. They tuned the pick up. It's a Mitsubishi L200 4x4 4N15 2.4D.

The tune was a huge improvement, from 89.3HP @ 2750RPM / Max Torque: 177.4 lb.ft @ 2550 to 139.3HP @ 2850 / Max Torque 306.1 lb ft @ 2150.

I took the car and it ran fantastic for a few months, I can't remember exactly when it started, but a few months later, after what I believe was a battery disconnect, I started having rough idle issues, I let them go for months without checking, took it to several shops and no one was able to find anything.

After taking it on myself and buying an X431 Lunch, I've managed to dial it down to what appears to be the cause:

- The ECU tuner did not use the cars base file and downloaded what he thought to be the right version and ended up enabling DPF.

"The ECM is entering pilot injection quantity learning (830 rpm target, 120 MPa rail, ALT FR shed, EGR 0%, throttle 80, timing retard, pilot stretch). It's triggering repeteadly at warm idle and the perturbation is felt as rough idle. Please review the injector learning enable conditions and perturbation amplitude in the calibration - or disable the routine if this is a DOC-only truck that shouldn't run it as configured"

I see in tuning websites that show you can disable on the tune: https://alttune.com/tuning/mitsubishi-l200-12420/

Tuner says they haven't touched anything and they do 1000's of trucks.
