timing question
 

do i still need to bridge gnd and ten in the diagnosic box to adjust the cas?? because its a mile out just with ms compensating

the ms has the same function for the same purpose, it's somewhere in megatune. change -10 to 10.

No need to bridge the jumpers with the MS-- that just sets the stock ECU to a base timing of X degrees (probably 10). As mentioned above in Megatune go to the Spark Settings screen and set 'Fixed Angle' to 10 degrees. Burn to ECU. Then use a light and adjust the 'Trigger Angle' (top of same screen) to make the light read a perfect 10 degrees on the crank pulley. (Burn after each adjustment). When it matched your base timing is set. Set the 'Fixed angle' back to -10 to make it use the table instead of the fixed 10 degrees and you're good to go...

Could you also do it by setting to 10 in MT then adjusting the CAS untill the light reads 10?

Yep-- it's arguably easier to do in software though.

I guess it depends on if you have a 12mm wrench or a laptop closer eh? ;)

well my Serial>USB lead is only 6" long ;)

Thanks Jerry

NP-- BTW my laptop sits in the seat too-- I either run back and forth, or have someone give me a hand...

all done, set to 14 degrees. cam timing was 3 teeth out which was not allowing me enough on the cas to adjust it, but its all sorted now.

So you set 'fixed angle' to 14 first right? Then adjusted the CAS to read 14 and then set 'fixed angle' back to -10? If so you're good to go...

10, 14, 20, makes no difference as long as it matches with the light and you set it back to -10 when you're done.

yeah exactly as you just said.
