I unhooked the 4 wire conector that you on hook when setting the timing, and now the car does not after fire nearly as much? it will still pop here and there but no where near as much or as loud as before? what can I do now? should I bump the base timing up? or should i turn it down, how much either way? it is at 4 or 6 right now? by disconecting the 4 wires what did it do to change it? the car does not have as much power right now so i don't want to leave it disconneted.

Also if I use teh zz4 ecm/prom am I going to noticed a diffrence over teh jet perf lg4 chip? ( I probably would spend around $400 for the kit) thanks

P.S by advanceing th ebase timing does it change the advance also? thanks

 

The wire you disconnect to set the timing is a single wire around the heater box that is tan with a black stripe. Im not quite sure what your asking with the ecm question

 

On the carbed cars it is a 4 wire connector I disconected it and th ecar stopped afterfireing, I am wondering why? should I dialin more timing or take some out? thanks
