Hello, a quick question/questions!

I just ordered a brand new Spark 3-UP and it will arrive tomorrow. I also ordered the V-tech tuning kit (maptuner + license + cable) separately since my Spark dealer couldn't/wouldn't add the tuning at the shop.

My question is, is it hard to do the tuning myself as a person who has never modified a motor vehicle before? I've read that you need to locate the OBD connector, where and how can I find it? How long will the initial tuning take?

What tuning would you recommend for me as a first time Spark owner with all stock parts? I was told the E85 is really good, anything negative about it except the fact that you need E85?

All in all, do you have any tips for me as I'm going to tune the Spark. I do not want to screw it up before I even put the machine in the water.

Peace out!

I believe the e85 tune needs different injectors. I wouldn't bother with e85 on a spark though, fuel economy will go down 10% right off the bat. Wouldn't be worth any tiny performance increase.

E85 tune needs nothing other than E85 fuel. But I wouldn't use it. It limits where you can get your fuel from because it doesn't run well on regular fuel. To each his own though.

okay, thanks for the answers. Maybe I'll go with the standard 110 hp fuel and can try the E85 after a while (since I can change between them with the maptuner).

Can anyone tell my how I find the OBD connector? Do I need any specific tools or will a regular set of screwdrivers etc suffice?

I am thankful for all help I can get since I'm new to all this

Remove the left side engine bay hatch. Below the coolant resivoir plugged into a dummy plug.

Vtech says to upgrade the injectors

There is quite a few on here running stock injectors. They were told upgraded injectors were recommended but not necessary

Yeah I'm sure the duty cycle is very high though. Sure you can get away with it, but not recommended usually ha.
