Best people to get into contact with would be SDS. I hear that their customer service is great.

Do you have a fast idle solenoid? I used one from an early injection vw jetta, they have a dual solenoid I just seperated them and used one. I can check my start up #'s. Do you have a wideband for tuning?

Make sure your closed loop setting is not on in the vaccuum range below -15Hg...(Turn off Closed loop while tuning anyway) Also check your TP throttle position setting....if it is like 12-15 at idle then make sure your fuel cut below TP setting is about 1 less than actual reading...Example on the SDS screen your TP setting is 13....then make fuel cut for TP at 12.

 

Also use the richnees knob and turn it richer to see if it smooths out the idle....if so increase the MP values in the idle vaccumm range usually in the -19 to -17 area....or the RPM fuel values can be increased in the 500-1500 rpm range.

 

Yes I have an SDS and I tuned it myself on the street...ran good for two years...on the G54b. Now I am using it on the 2JZ and converted it to 6 cyl.
