I have am having issues with Sync loss errors code 38, and 39. I cant find any solid ways to fix it.

my set up is;
94 chassis
99 motor with, tps, water temp sensor, vics,injectors.
94 coils
94 cas

Is the issue just a part of running a CAS ?

I have the 99 crank sensor i could put on but kinda dont want to.

I attached a log, the sync loss is at the end of it.

 

MS2V3 or DIYPNP?

 

Ms2v3

 

You need to add the optoisolation circuit that is present in the MS2 for the crank sensor, to the cam sensor as well.

 

Do you have a link to a correct diagram and what pins ?

I googled it but found a few diffrent topics on it.

 

The cam input it what is labled SPR1.

 

Ok that's the one I was looking at.

Just gotta make sure if have the parts then.

 

Remember to remove the parts from your current cam circuit (ie the 5V pullups and the cap if you have one).

 

I will have to look at my manual when I get home to a computer to see what to check and make sure I remove.

Thanks for all the help it will be nice to get rid of thu sync loss.

 

I built this following the mega manual and the wikki page, from what I can tell there is nothing about installing a cap or 5v pull up right ?

If I would have installed it where would I ? I want to be sure I know where to look and that I'm not just missing something.

 

I think he was assuming you had built MSI inputs, not MSII.

 

Well since the local radioshack sucks i have no spare 4n25.

yay just ordered a 55 cent part and pay $3 dollars in shipping.
