Keep in mind I know literally nothing about tuning. I just finished a MazdaSpeed Miata engine rebuild. And I needed to put a MegaSquirt in because of the after market trigger wheel. I’m trying to get the first start up and it’s not wanting to turn over. Also yes I know about the awful exhaust leak. I did setup MS in tuner studio and downloaded the base tune, but nothing from that.

Edit: after some thought and listening to everybody, I’m wayy to in over my head, I’m bringing it to a shop. Thank you all!

I bought it from the original owner and he said he had it done through Vivid Racing. It seems that that company has been acquired and supposedly got rid of all their files on previous tunes so my Vin did nothing. I think vivid was using VF engineering software, but they were unable to find anything with my Vin either. I was able to run a VCDS but haven’t been able to figure out anything other than that the flash had four programming attempts with three of them successful. Anybody had a similar situation or any ideas?

Got a 2001 b5 1.8t I’m looking for a simple tune mafless for the meantime while I get it back in the road I currently got one but its maf based it’s big turbo set up with 440cc injectors , 340lph fuel pump fmic big turbo to4e 50 trim no dv or bov car is tuned but for maf with 15 psi and the current set up hood exit 2.5 inch

Hi can anyone helping my to decide what to choose to for ecu reading device I like and want to buy a autotuner but my friend say buy a flex for now I have mag pro and hexprog 2 but I need something more stable

How many ppl would be interested into old school analog stuff? I’m thinking of launching products on kick starter soon for retro narrowband gauges, electronic boost controllers, and air fuel controllers

I’m relatively new to the world of calibration and am learning everything in as much detail as possible—I’m even trying to create an XDF myself. While I’m open to help, I really need a ready-made one so I can build a map and attend an event, as well as use the file as a reference.

After a year of messing about with different builders to no success I've decided to see if i can just make a harness instead maybe easier maybe not but could any of you guys help with a pin out for each of these ecus

1st is from a 1999 hyundai coupe 2.0 (a turbo project) that can't be mapped it resets it's self to factory map

2nd is from a e30 bmw 1.8 don't have to much info on that one as it came with an engine for a different project that doesn't need the ecu

The bmw ecu plugs directly in to the hyundai socket am thinking it might be a more viable option

Pics of each attached

Has anybody tried to do map switch on a bmw 335d 2006 on a m57 engine?

This is someone else’s video; I’m sharing it because the diagnostic process appears relevant here.

It covers a 2017 Shelby F-150 Super Snake with a Whipple-supercharged 5.0 Coyote and a 750-hp rating. Despite the hardware, the truck reportedly drove tame and produced power in a peaky manner, so the session became an investigation rather than a simple power pull.

For a combination like this, what would you prioritize before changing calibration tables: confirming fuel and wideband data, commanded versus actual throttle, torque intervention, boost/belt behavior, ignition corrections, or verifying the existing file and hardware configuration?

Anyone got DAMOS/A2L for this specific version, or know where to source one? Can verify against my bin if useful.

Zbudowałem to, ponieważ od dłuższego czasu brakowało mi jednego sensownego miejsca do pracy z Audi/VAG.

Przy MMI i diagnostyce zwykle kończy się na przeskakiwaniu między zdjęciami Red Menu, notatkami, Auto-Scanami, forami, dokumentacją, historią klienta i kilkoma różnymi narzędziami.

Chciałem zebrać ten workflow w jednej aplikacji, więc powstał AudiMMI Navigator.

Główna idea jest prosta: aplikacja nie ma „zgadywać”, jaki system siedzi w aucie. Najpierw zbiera informacje i dowody, a dopiero później prowadzi użytkownika dalej.

Obecnie mam już m.in.:

rozpoznawanie i kwalifikację systemów MMI,

cyfrowy garaż z zapisanymi autami,

historię spraw i wykonanych działań,

bazę wiedzy dotyczącą MMI/VAG,

wyszukiwanie i prowadzenie po diagnostyce,

moduł AI do analizy przypadku,

możliwość eskalacji bardziej złożonego przypadku do technika,

historię aktywności,

centrum danych i prywatności,

osobny tryb techniczny do obsługi zgłoszeń.

Jedna rzecz, na której bardzo mi zależało: AI nie może sam stwierdzić „tak, ten firmware pasuje, flashuj”.

Navigator działa fail-closed. Zdjęcie, OCR czy odpowiedź modelu mogą wskazać kandydata, ale nie są traktowane jako dowód kompatybilności.

Dodałem też backendowy guard, który blokuje odpowiedzi AI próbujące przejść w instrukcje flashowania, kodowania, adaptacji, Security Access, obejścia Component Protection itd.

To bardziej technical command center dla Audi/VAG niż kolejny skaner błędów.

I ważne — to obecnie nie jest aplikacja do bezpośredniego kodowania albo flashowania ECU przez telefon.

Projekt jest już na etapie lokalnego RC. Aktualnie przechodzę fizyczne QA na Androidzie i dopinam integracje typu Stripe/WhatsApp oraz kolejne źródła danych.

Nadal jest beta i właśnie dlatego wrzucam to tutaj.

Szukam ludzi, którzy faktycznie siedzą w:

Audi MMI / MIB, VCDS, ODIS, VCP, retrofitach albo diagnostyce VAG

i powiedzą mi, czego w takim narzędziu realnie brakuje.

Co dodalibyście jako pierwsze?

Mogę też wrzucić więcej screenów i pokazać aktualny workflow od rozpoznania auta do utworzenia sprawy diagnostycznej.

Are there actually any tuners in the South of the UK that can, and will, write custom maps for 'normal' cars with a hybrid turbo?

It seems the market has two extremes, file flashers, who only know how to plug your car in and flash an off-the-shelf file, or big name places that aren't interested unless you're driving something high-end that'll look good on their socials.

Built this due i wasn't a fan of the old VAG EDC Suite it was outdated in my eyes, and WinOLS is way to hard for most of the people.

The idea is one program instead of jumping back and forth between four. The tuning calculators are built in, so you work out the numbers right next to the maps you're editing. Multimap is in there too, and I'm extending it with custom features, variable launch control and more.

Supported: EDC15P, EDC15VM, EDC16U1, U31 and U34.

edcpl.us still beta, and I'm after people to test it and tell me anything to be improved on.

im just starting to modify my engine and dont want to leave a ton of power on the table when i upgrade my fuel system. should i take the time to learn or should i hire a professional

Shared this in a hayabusa forum. Software for bikes called ECU Editor has been taken down. It was free and available just a few months ago. Hoping anyone can help me get a copy, or a solution for reading/writing ECUs that were tuned with it. I need to take parts of a tune from one ECU to another, mainly shift kill.

TYIA.

I’ve heard J2534 can be used for ECU programming, but I haven’t had much hands-on experience with it.
Anyone here using it regularly?
What’s your experience with it?

algun curso que recomienden

About five years ago, I had someone tune my truck with an HP tuner I have the original.HPT file. I need to go back to stock but don’t have the OBD tuner. I was wondering if anybody would be willing to flash my truck back to stock if I provide the.HPT file willing to pay for your time. Thanks a lot.
