I redid my connections to the distributer today and I used my friends chipped ecu for a B-series and it worked but it pings at the lower rpm. But when I plug in the other ecu which is a vx it doesn't rev again. I'm figuring that is this shitty *** ecu which I am going to get chipped. I don't know-what you guys think?

 

how did you connect the wires?

soldering i hope

 

this is hmt buddy, nothing is guaranteed.

 

Even twisting wires together by hand and letting them lay there on the floor and get loose huh

 

when i first did my mpfi swap, i had the same problem. Code 4, and the 3200 rpm rev limit. Turns out, the two extra wires i had to run were reversed...so i switched em around and reset the ecu....voila...no code, no limiter Believe it or not, there is a polarity so to speak to those wires. I just got rid of my code 9 today by doing the same thing.
