Hey all,

Bad english. Read the bottom one. My bad.

 

I think what you're asking is, if you already have a base flash and you want a new one, should you send the current one or your stock one...

I guess that depends on how well suited your current tune is... if you first tune was strong, then send logs + that tune over to the new tuner for minor fixing.

If you aren't sure, probably just retune from stock

 

Lets put it this way;

ECU "A" is my original ECU.

ECU "B" is another ECU I will buy from other for a spare ECU.

I like to have the ECU "B" to be reflashed, hoping to get more hp/performance.

If I don't like that tuning, I can switch back to ECU "A" which is my original ECU anytime.

Is it a good idea to do so? What or who is the best tuning for ECUs?

Or, what do you recommend if I want to buy performance ECU to replace my original ECU?

 

if you have a laptop you can get a tactrix cable, logging software and ecuflash software and make unlimited tunes.

 

Yea, like Mellon said.. It's easier to flash your ecu back to stock than to change it out. Quicker too. Takes about a minute to flash back to stock.

 

I see.

But I think I will just stick to my second plan. Where I would buy another ECU for a spare. That ECU will be the one that I am going to reflash.

Thank you for the replies.
