Low Impedance Injector driver info

[the Fredericks]

I modify factory ECMs using P&H drivers to run the low impedance injectors.
I use the Cherry Semiconductor P&H drivers to do so.  So far, I've only done
GN ECMs (148s), but could easily do a batch fire ECM like the Syclone ones.
Contact me direct if you need more info.
