Micro Chiptuning Arvostelua 5

Do not buy from them.
They send a useless chip and give 0 aftersales service.
Landline is false and the whatsapp works just to send selling vouchures.

Dear Sir/Madam, after a few thousand kilometers the system indicated errors. I sent the chip for inspection. They said they would send a new one. After that, I never heard anything from the company again. They read my message on WhatsApp but then did nothing with it! Very poor.

Betrüger,habe den Chip zürickgeschickt.Keine rückzahlung von 130,00 Euro bekommen.Micro Chiptuning kann man nicht Vertrauen.Ihr Gan..

The good thing: Fast delivery and replies to mail inquiries. Low battery consumption.
The bad thing: Product is fake and thus extreme expensive for some blinking LEDs compared to other chip tuning scams (which is also waste of money).
They sell the product either with a connector between motor management and ECU or as OBD port plug (both contain the same circuit board ...).
Did some testing including a blind test for 3 months. Guess what: The one who knew had the impression it was a little better, The one who didn't was not aware the car was chip tuned (no difference) and was surprised it was "tuned" as he couldn't find any difference.
In short: At best this slow battery drainer is an OBD2 port Scanner that gives you the state of your car in color code blinking LEDs. But this cannot be a chip-tuning device therefore it lacks too many components on its circuit board. For sure a "better" technical board (still scam) than other similar products your find on Ali&co Chinese or drop shippers sites (whatever brand name ... Nitro/eco/Thurton/XYZ....). But their scam cost a fraction of what is asked here. Anyway at best you bought (I guess for as far those very positive reviews were legit.) a placebo chip tuning device for your car. A candle might give you the same performance increase but not save in a car?! The active component the "PIC18F25K80" has 32KB of memory (wow some KB's more than some other scams). Do not waste your money on this. Either go to a tuner or buy a generic working memory map (yep it won't fit in that 32KB even if it claims "on the spot tuning as it runs"). It will cost some more but at least it will give also some real performance instead of the idea.
