Ok so I have been trying to find a sturn cam sync but have had no luck in doing so. So if anybody has a good one let me know or if there is an alternative to use let me know what that is. any help would be greatley appreciated. thanks
I have one and Ive been looking to buy a second one. But I cant seem to find the same part number. I hate to say it but i think it might be discontinued.
ya pn is 8914. and I know it has been discontinued cause MSD told me that when I emailed them. but I am seeing if anybody has one they aree selling or if they know an alternative to using the that cam sync generator. I am using pn8916 which is a regular cam sync generator but i know that the saturn cam sync has the out put for the ecm. so that is receives a cam signal. right now the was i have my msd setup i am not getting a cam signal to the ecm but the car runs fine. but it acts up after 5000 rpms and that is due to lack of cam signal.
That's weird, although it may be different with an eco, I have no cam sensor hooked up right now and have no problems in the high rpms.
ya a z24 has a cam sensor. eco doesn't
I am sure somebody else has ran into this problem
so a cam sync reads the cam position without a CPS pad on the cam...
/me is listening...
my intake cam does not have the cps pad... one day i'd like to weld one on... but im open to other options as well...
i am not having problems in high rpms, im having problems starting hot, and idling...

I seriously doubt that. The cam signal does nothing for high RPM. The only point of a cam signal is for sequential injection at low rpm for emissions purposes. At high rpm your duty cycle increases to the point that sequential fire has minimal benefit. Besides, your PCM switches to batch fire under PE anyways, so you're lack of cam signal is completely irrelevant. Explain what you mean by "acting up."

The cam sync reads when one of the cylinders fire (I believe #4) and it then outputs a readable cam signal for the PCM. This works because we have a wasted spark ignition. It might help with idling, but I doubt it will help with startup. Your issue is clearly with the cam itself...I doubt that lift and duration is going to be friendly at idle regardless.
I have no signiture
my major idle issue is that the car wants to on occasion rev and hold around 3000 RPMs on kick down, and it won't drop until i get below 5 MPH... right now its only doing it with the AC on, but after the learned values get erased on an ECM flash, it does it alot while its learning...

We have talked about this but for everyone else mine also does the same exact thing. I will eventually hook up the cam sync and see if it is the issue. Mine does it with or without AC.

Sounds like it could be cam sensor related. I don't know the algorithm, but the PCM will try and prevent a stall by opening up the IAC if it feels a stall is imminent. With the extra load from the AC and the cams, the PCM might just be overcompensating. I don't know for sure though. Wouldn't hurt to try the cam sync.
I have no signiture
mine does that as well. I just want to have a cam signal going to the pcm. I just want to make sure my pcm is getting all the right signals.
can any one link me to a picture of a cam sync? what is involved in installing it?
Its a small black box maybe 1.5 inch x 2 inch...this is going from memory. It has a signal wire to wrap around the number 4 plug wire, a ground, a wire to go to the ecu, and I think also a power wire.
I need to dig it out before I can take pics...its somewhere in my collection of stuff.
does the ecu wire tap in to the cps wires
there is one msd 8914 i just found on amazon.com for 65 dollars.

pretty much exactly what I was going to say.
lol just ordered it. hope they actually have one and it isn't a miss print.

be sure to post back up when your problem is still there.
I had no cam sync on the skwirl when I had it running MSD, and I had it up to 7500rpm daily and 8100rpm on a few occasions and never had any problems.
Yea I have rodimus old msd set up so im running the cam sync but I thought I remember PJ talking about how its really no use to have basically just keeps the CEL from coming on.
well this is what was said after I ordered the cam sync on amazon
"Kris from HPF here. I’ve just been informed from our purchasing department that we had sold our last set of those Caps about 3-4 weeks ago and haven’t been able to update our amazon store. After trying to acqurie the part, we had found out it has been discontinued. We do apologize for the inconvenience but when you can give me a call or send an email letting me know what you would like to do. We can try to find an alternative for the item or you can let me know if you are okay waiting for the item as well."
if its discontinued, why are they giving you the option of waiting?
get your money back asap.
get money back ASAP and then ask them to find an alternative...
