Neo help!!!!! Please!!!!

[dsmtnr]

I done a search and couldn't find anything. So I need help. I have a Neo in my 1990 GSX. when i got it it was the old version so I had Apexi reflash it and up date it. Well I installed it and when I go to the monitor part of it my tach (on the NEO) is way off and slow to respond. Do I have something set wrong? Please if anybody knows whats up it would be greatly appreiciated.

Try changing it to 2 cylinder. On some of the older dsm's the 4 cylinder set up reads off. If this doesn't work check your ground and tach/rpm signal.

i have a 1990 GSX too!
How is the apexi neo working for you and what all do you have done to your car?
I'm trying to find out some info about the neo but haven't found much.

Call apexi and find out if there's a bug in their reflash?

I've call Apexi and sent it back to get reflashed, They said everything is good. I've double check all my ground. I even tried a jumper wire from the CAS right to the NEO and still nothing. The tach (on the Neo) works great at idle but once I start driving or raising RPM's any it lags and reads about 1000 rpm off. I dont really mind I have a good tach on my car. Only thing i'm worried about is if it affecting my tuning or is the problem just in monitor mood.

Have you checked the noise filters etc?

??? noise filters ???

They're these little capacitor looking things. I don't know much about them, but they work with the tach.
