tach install

[nismoracer22]

Anyone know where to hook up a tach on a sr20det? and im not talking bout from the ecu cuz I know bout that I was wondering if there was another place cuz I know you can hook it up to the ignition coil but being a direct ignition car dont know how that would be done...thanx.

Whats wrong with the stock tach?

[nismoracer22]

head upgrade and i want to make sure that it is going to accurate at higher revs

Can tap from coilpack wire, but ECU would be much easier and less messy.

The stock tach will be plenty accurate up to 9k rpm, waste of money for aftermarket tach IMHO.

Which wire and how would the ECU be cheaper if your just tappin a wire? the reason i dont want to tap the ECU is it gives a funky signal...like for my turbo timer....i dont know why though....im guessin cuz if the wirein being all spliced together there a couple times over.

My AVC-R taps the ECU RPM signal and gives a perfect signal, I don't know if you might have a bad connection or something.

Always solder your connections, don't cheap out by using the twist and tape method.

ECU would be less messy not cheaper, as you don't have to run wires to the engine bay.

I am not sure which wire on the coil pack, but its the one you clamp your timing light to. If you have one, test it and find out.

ok thanx...sorry bout that...i read it wrong. well ill try sodering the turbo timer to the ecu wire and if that works for me ill do the same from the tach but if not ill find that pisky wire and in case and one else needs to know what wire ill post a picture. thanx again.

3m also has vampire clips to splice into wires. works pretty well too.

but soldering is always better.

those are the type of connecters i am useing now....i dont know if its the wireing or those conncerts but one of them sux
