AHHHHHHH lol. Ok so i got my msd 6al in an i put a 4000 for my break in. I drove it today an tryed to go past 4. I was thinking i got ripped off. Went home called msd an the guy told me that alot of the guys who call about rx7's have this same problem. He told me that its trial an error on getting theright rpm chip. Is this true. Should i try going with a lower number like a 3600 an see what happens i would think it wouldnt be that far off. I have noticed something like that when i put my tach in its about 250 300 off at higher rpm.

 

you have a single 6AL box?
You will not get full ignition cut with a single box

 

^ One box will not stop you. You need 3 boxes due to the way the trailing is setup

 

ok now i know that thanks but three i thought it was only 2 boxes. but thats helpfull to know. So the two step wont work on the single coil then.

 

unless you only run on the leading coil lol

 

is that possible if so will it still run right were would i run the plugs to the leading or trailing

 

Run the box IN and OUT of your Leading Coil.
Here try this Link( thanks to RETED.) http://www.fc3spro.com/TECH/MODS/IGN/cdi.htm

 

yeah thats how i have it ran to the leading. i want to delete my leading an just run my trailing
