ok this make take the thread in new direction but its related.
pin 7 might work but im missing it = (
Pin 41 120° signal from ECU does not need resistor and tach reads directly.
Pin 42 1° signal need power bump up to work
Next problem my tach reads off like its reading a 4 cylinders.
started of my issue
Blitz Tach with Live unit.
oringinal jumped from Pin 41 with out any resistor or mod
this worked but it was reading off. same or similar symtoms run like a 4 cyclinder
with many attempts to reset the Gauge and live unit I
as per document: http://www.blitzperformancesales.com/techsupport/pdf/rm-dc2.pdf
since my harness does not have Tach (pin7) i just used 180° signal (word usage told to me?) that was wired in previosly by some else(I didn't make or mod harness).
or use another pin from unused location like speed sig(pin 53) to insert into pin 7 see if that works.
(im having problems submiting post on this forum?)

how do you figure the resistor value for the particular brand tach?
rb20det aftermarket tach install?, need info

i well im a idiot i missed counted >.< traced the tach signal wire up the wiring harness with it T's off and jumped it there.
as for the blitz tach its sucks its just not sensitive enough. so i put my Jumbo Apexi tach that I had sitting in the closet for who knows how many years(so old the can't find online docs for it any more). soldered in a resistor from the main power to tach line. set it to 6 cylinder and it shows that car idling under 1000rpms. blitz when i finaly got set still showed 1200rpms or more...
Hey thanx.. ^.^
