Nissan Skyline Patch Loom SM4

[MRMRacing]

Here is the result for Nissan skyline patch loom.

There is number of advantage to the patch loom than a plug-in ECU.

Better second hand value since the SM4 can be used to much more.
You can use it to your other vehicles.
No hidden electronics inside connectors (like other brands do have), external relay for easy fault finding.
Two pin connector for Autotuning (to analyzer)
Six pin connector for spare O/P & I/P (use for launch control and more). No cut and crimp to stock harness.
This model is used with external multiplexer, easy fitting when using CDI instead.Also have connectors with 300 mm wire for Supra 89-92, Supra 93-98, Nissan 88pin (200 SX and more), Nissan 76 pin (Skyline and more). See pic.

Will make up SM4 pach looms for the Supra soon.

The skyline here is made for Multiplexer with fully sequential ignition, but could also be made for waste spark mode.

Can you get Honda Integra DC5 K20A engine ecu connector? I am looking for the ecu side connector to make a patch to sm4.

[MRMRacing]

Can you post a pic of it and how many pins it has, and the brand if you know!

Pic of latest Skyline patch-loom with wasted spark.
2-pin connector for analyzer.
6-pin connector for spare I/P & O/P.

Can you PM me with an approximate price in USD for a 94 Supra patch harness? I know they are not available yet, but do you have an approximate release date as well? Thanks!

The Supra are soon ready, are you using the stock dual turbos with all valves or a single turbo/waste-gate? Stock ignitor will not work with high boost, HKS ignitor or CDI can be used. If I know this from start the Patch loom can be custom made.

It's not for me, but for a friend. I'm trying to get him away from the AEM he is wanting to run. The only other thing he has looked at is the MoTeC setup from Titan Motorsports, as they offer a patch harness.

The car has a single turbo on it, and would be using some sort of external CDI, either an HKS ignitor or a 500R.

I have now sold five Nissan Skyline Patch harness that is working grate, some use the adjustable camshaft, some stock trigger disc and other crank mounted sensor.

I now have to get more looms made!

Robert, if you don't mind me asking: what material are you using to pot the OEM harness connector?

[MRMRacing]

I buy them ready made with wirings hanging out from Autosport wiring Texas. I then fit the Sm4 conector and others.

any benefits for a evo ix? instead of pnp sm4 a normal sm4 with patch harness?

[MRMRacing]

The evo ix has more inputs and outputs so no except for that Sm4 can be used in more cars...
The PnP has some special functions so if using it on an EVO 9 it is much simpler.

thanks for the advice. Am waiting for my local dealer to return from vacation then am ordering it. :)
