Hi guys.I have some questions for you :D

1)I want to buy winols.Which one should I buy?Should I go for the full version and how much does it cost?
2)If I buy winols,will I be able to buy reliable mappacks?How many maps are included in them?Are they enough to properly tune a vehicle or should I go for a dammos instead?Will I have to search manually for maps even if I have a mappack?
3)Which hardware should I buy?I have Kess Master and I will probably buy K-tag Master.They are good tools but I am intrested in tuning Nissan GTR and hypercars as well like Porsch Spyder.Should I go for EcuTek?(For each hardware,tell me if it corrects checksums automatically or if I will have to do it manually through Winols)
4)Can you suggest a universal diagnostic tool and some diagnostic tools for datalogging while developing a file on the dyno/road?
5)What else do I need for OEM ECUs except for a lamda sensor and a battery supply unit?

Thank you in advance and sorry for the unlimited questions

hello are you a company ?
