throttle response setting
 

I just received a new ECU for my P120 from Jetcat today. It works perfectly and the engine starts and runs fine after adjusting the starting voltage for the pump.
My question is if it is OK to use the fast throttle response setting on the ECU or the normal setting since I have one of the very early p-120s? The normal spool up time is now about 8 seconds from idle to full power.

My old ecu was fine but I lent it to a good friend with a problem ECU and it got destroyed..
Thanks,
Jay
