hosestop@msn.com Posted June 1, 2010 Report Share Posted June 1, 2010 Hey all Brad from Hosestop (the Datsun paint shop)etc. I have my Black 4dr SR running and ran the ECU TACH wire to dash area but wonder what tach will work with factory signal,was thinking maybe Infinity product from JY. or maybe aftermarket tach that may work with signal wire due to coil packs it may be hard to find one to read Nissan signal,wish stock tach could work ,I heard will fry my ECU.thanks for info later.

Creepy Cruiser Posted June 1, 2010 Report Share Posted June 1, 2010 There is a good "how to" article in an old DQ, that shows how to just change the board on the factory 510 tach to a modern one, in order to make it work with the new motor. Also, if you do some searching around here and there, there are a few other variations of that "how to", showing the way to update it, and make it work. Quote Link to comment
danfiveten Posted June 1, 2010 Report Share Posted June 1, 2010 I know someone that modified 96 sentra se-r gauges to fit in our stock housings, took some time but it looks almost factory. Quote Link to comment
Icehouse Posted June 1, 2010 Report Share Posted June 1, 2010 The factory inductive style tach can be made to work with the SR or any 4 cylinder engine. Run the coil pack wire power through the white wires on the back of the factory tach. Quote Link to comment
inline4 Posted June 1, 2010 Report Share Posted June 1, 2010 or if you have a 73 tach (3 wire) hook up a 1k ohm (I believe) resistor and wire it up to pin #2, which is tach output on the ecu. Quote Link to comment

hosestop@msn.com Posted June 3, 2010 Author Report Share Posted June 3, 2010 I have heard people zap ecu's , so it's the white tach wire to tach wire from ECU with a resistor in line ,trying not to cut up tach ,I also hear they use 82-85 maxima guts in 510 tach housing , I may get a VDO or something that goes in hole and works ,I don't care if matches that much.

spoolinitup33 Posted June 4, 2010 Report Share Posted June 4, 2010 I used an Autometer tach, it works fine. You just have to figure out how many times to push the button on them to get them to work with a four cylinder, or whatever cylinder engine you have. Quote Link to comment
sycloned916 Posted June 4, 2010 Report Share Posted June 4, 2010 Try looking at the autometer Tach adapt Part# ATM-9117 its for the DIS coil pack , it changes the signal to use a tach. I wouldn't jerry rig do it right. Quote Link to comment

Hey thanks will check it out ,ECUs cost too much,have VDO turbo gauge ,SW. mech. oil gauge,auto meters are cheap thats good !running my car all stock 7psi ,runs great and gas mileage is good, need to paint my fac. black 4dr and maybe 65 fairlady srde next project ,also I make hoses and brake lines.
