Never had a problem after a year with haltech till now.

here is my old thread https://www.rx7club.com/forum/showth...threadid=70620


Ok, a week ago I thought I fixed my problem with my ignition.

Here is what I did.
1. Repliced crank angle sensor wires from the haltech harness.
2. Replaced CAS
3.Replaced spark plugs, wires, twice the coils(leading and trailing)
Even threw in an extra wire for ground on the leading coil.
4.Relocated Leading coil because it was a little closer to CAS, now
is farther awar (even from stock location) and bolted to chassis.
5.Routed spark plug wire far away from CAS also routed the trigger
cables futher away from spark plug wires and other wires.

6. can't remember but I've think i've done everything I could. Even played with setting on the haltech.

Bought
a MSD 6a but I don't think that will help cause I know the Rx7 coils
are the best OEM.

The only thing I notice was when I turn down the boost to stock
levels (5 psi), it actually works better. You feel a slight stubble
as it builds around 3k to 4.5k and then can of goes away. If i turn
back the boost up to 10 psi the backfires and more noticable.

Ok guys someone shade some light in here cause I don't feel like
dealing with the car anymore.
