my vats seems to be toast, so i picked up one of these: http://cgi.ebay.com/ebaymotors/GM-VA...item3361cd0bed with the duel frequency option, but now im stuck on wich out put i need to use on my car (89RS camaro 305 TBI). the instructions dont say how to tell wich one the car needs so if anyone can give help with this or has used one it would be great.

 

Do your instruction tell you what the options are? Everywhere I search the internet I see two frequencies, 50Hz and 30Hz. Seems the 50Hz is the standard.

Try one, doesn't work then try the other.

 

i mite end up having to do that, im just wondering if anyone knew befor i do that, or if it could hurt the ECM.

 

Won't hurt anything - either the ECM will get the right signal and fire the injectors, or it won't.

 

ok cool

 

just put 1 in my 88 camaro cause i put a 92 sd tpi in and had to bypass the vatts mine was the 30 hz. but either way just try both one of them will work

 

I just bought an '89 RS with the 2.8... It didn't have the original key switch or any kind of switch for that matter... I bypassed the starter enable relay... Now i have to get the right signal to the fuel... With that being said i was wondering if the bypass from backerelectronix requires the factory key or will i be able to get my car going with it? Someone... Anyone.... please help me... thanx

 

It don't matter what key u use all the box from bakerelectronix does is enable thee fuel to the injectors. Use whatever hey switch you like, I bought the dual frequency box that's what I wld suggest

 

thanx... znate... yea was planning to get the dfvats... just needed some reassurance... really appriciate your input... again thanx

 

not a problem glad to help!!
