ignition ?s
I'd appreciate any links to ignition system basics. I've searched and read lots of hype and arguments on whether or not amplifiers work, which is best, blah blah., but really would like some links to help me research the subject myself, starting with ignition basics and working my way through the technical minutiae of the FD system and upgrades.
This research is in response to what seems to be ignition breakup at 6500 rpm running open exhaust, intake, pfc, ic, new plugs and wires. Car pulls strong through that range at ~12 psi, but held steady at 6k it stutters and smokes a bit... Sorry, I'm sure there is a fantastic thread out there but my searches didn't turn it up. |
Kent,
Did you get the PFC tuned? The stock ignition is actually pretty good (up to a point). |
I have heard really good things about the HKS TwinPower.
Rx7store is selling them for a decent price. http://www.rx7store.net/index.asp?Pa...S&Category=276 |

C'mon linkmaster, hook me up! :) I would invest in a tune first. Without a tune on your car, your not much better than the rechipped ECU's that Pettit/M2 or the others offer. As for the ignition amplifier, here's the one I'll be going with (FC1000 by Jacobs Electronics): http://www.rx7.com/store/rx7/fdignition.html |

You think its a better buy or there is a harness wire not included at this price? Will you be changing your coil too? I am also wondering what would be a reasonable price coil to upgrade too... |

If you have a m2 or pettit ecu,get the twinpower.I have it, and it made a difference in power and mpgs.Worth the $$.

regarding the jacobs system
This is a true capacitive discharge system, not just a simple restrike system like the HKS Twin-Power. |
