Burn times suddenly really long

[Zafer Altan]

My burn times are randomly way to long for the stuff I use, First I could easily get in a 100km orbit around kerbin. The burn times are randomly like 90 seconds or so, but first this was like 30 seconds or less. I use the exact same ship. Does a mod change these burn times or something?

Well, there certainly might be mods and configs around that change your engine parameters. Did you install something suspicious?

Are you sure you have extremely close amount of fuel, same stage and engines activated, and same delta v of manourver required?

Yes, I have alot of delta V and the burn times are way longer then usual. Craft is exactly the same.

I mean similar amount of fuel in both cases.

Have you actually done these burns, or is it just the estimated burn time from the Manuever Node?   If you have just staged your ship, and the engine that is now active has never been fired, the estimated burn time is usually way off.   Gently 'burp' the engine so it doesn't change your orbit much, and the estimated burn time should return to an accurate level.

Well you are not listing "the stuff you use."

If the ship in question was using a nuclear engine and you added mods by Nertea like Kerbal Atomics, Nertea totally changes the fuels used by some engines.

The totally different fuels that are added have different volumes and ISPs for the engines....

That's actually why I don't use Kerbal Atomics....

Included with that mod is a Liquid Fuel cfg file somewhere which you can relocate to the "patches" folder for that mod so the engines only use liquid fuel like stock nuclear engines instead of using Liquid Hydrogen or whatever they are switched to....(I forget specifically what exact fuel everything gets switched to by default).

I would go to the thread for that mod for specifics....

I prefer the Lightbulb Atomic engine included in Recycled Parts:
