Converting 202 to DIS

Will this adapter work to get my Tacho to work on the GTR Dash?

Everything is fine in Tunepro but nothing on the car Tacho

It looks right to me. I assume the original tacho is off the factory coil? And you would use this on the digital tacho out from the ignition module? Its not the only way to do it, but the price seems pretty good for an off the shelf aftermarket product.

Yes the original Tach is a signal off the coil so worked fine with the old locked Dizzy and module.
Yes I have seen other solutions in the converting to DIS thread but I'm looking for something that I don't have to make and can be easily be replaced or removed. (never know one day it might be a 161S with a carby again).

Thanks again for all the help.

Actually got to drive it up my driveway on the weekend and all seems to work well.

Had the car on the dyno Saturday.
All running sweet but idle still a bit average.
Considering adding an IAC to improve it.

Happy with the results regardless

Nice one! Yes IAC is worth it, especially for cold start where it can add air so the ecm can add fuel, thus its you're choke.

What cam specs and other engine specs does it have? That's quite a stout result

[inj gtr202]

Attached are the Head flow and Cam specs.

The rest of the package is just your standard 202 stuff. Flat tops, Starfire rods, balanced, oil system opened up etc.

[vlad01]

That's a pretty decent sized cam.

That's a pretty decent sized cam.

Hence the need for an IAC

Cold starts and car parks are definitely not my friend at the moment

A little trick I used to do with very large profile cams, was lean mixture and higher timing. Example, a 308 Holden large solid profile. 15:1AFR and 30 degree timing in those areas. There's some BIN's of mine like this in the custom tune area. That does smooth them out as they're not producing torque when set like that.
