suddenly lean when throttle is pressed from cruise% to WOT

[touge tom]

hey fella's.

thomas here,

my board no#31517

my engine setup is a b20/pr3 vtec combo.

12.5:1 static comp with buddyclub spec3+ cams and 0.5mm over bore 2126cc.

i use the 2001 stock type r map to begin with.

at the moment i'm street calibrating the s300 v3. low cam fuel tables only. ive sorted out my air/fuel ratio's but when beginning from a standing start as I release the clutch and it makes contact with the flywheel. the A/F leans out past 17:1 A/F.
and also while at cruising engine vacuum and then going WOT it leans out the same with hesitation, so I gotta back off.

anyone got a clue? i'll attach my rom file for someone to look over it... please?

Your map shows you are in closed loop. You may have to adjust the "rate of change" parameters. There are some suggested values to use on the board. Also look into the "throttle tip in" parameters.
