Anyone hook up a jacob's nmm on a TPI?? more specifically an 87 with external coil? i heard you need a spark box like msd for the electronics....will the fuel pressure sensor still work with the high FI pressures, or do the pressures drop down low enough with the juice active?

Anybody?

thanks
Jeremy

 

I used to have one on my 1987 305 TPI with stock ignition.

You need to make sure you buy the MasterMind kit with the correct Hobbs switch (adjustable range is ~30 - 50 psig). The kit for non-EFI cars contains a Hobbs switch that's adjustable from ~1 - 7 psig.

Call Jacobs at (800) 627-8800. If you don't have the correct switch, you can order one directly.
