Hi guys

I've never needed to adjust this before but recently I've been flying loads with my own 120SX. On start I'm now getting a good lick of orange flame out the back indicating to me the pumps starting to bed In and as a result supplying too much fuel. I got to the correct menu OK. Could you explain the difference between uaccel1 and 2 please. Had look in the instructions but these didn't explain the differences.

Thanks for any help

Cheers, Alex
