Hey m8s.
I cant match the timing with s300. I go to Online menu and click the set timing option. Then i check with my timing light and i see 9 degree when i should see 16 degree. I move the dizzy up and down and the timining stay stock in 9. When i move down in the program to 9, with my timing light i see 3 degree.
The dizzy and the oil pump is obd2 and i use a obd2 to obd1 jumper harness and a p28 ecu.

Help???.

An OBD2 PRelude distributor is not adjustable. You will probably need to use an OBD1 distributor for it to be adjustable.

Keep in mind also that any changes to the cam timing will throw off the reading at the distributor. Also if hte head or block have been machined at all this will throw things off.

O ok....got that.
If i see 7 degree diff at idle, is it safe to give 7 degree to the entire map???. If ill do it i should see 34 degree around 8000 rpm...thats no to much right?
Thanks for fast reply dude.

That is not a good way to adjust hte timing. The base timing should be set and if you cannot do that with the stock distributor then you will need to convert to an OBD1 adjustable distributor.
