Oiwa Garage Tech Note
"These modules are heat-sensitive. A truck that stalls hot and fires again cold is the classic module story - swap it before you chase the fuel system."
Frequently Asked Questions
Does the module need programming?
No. The module is a direct replacement with nothing to reset.
How do I know the ignition module has failed?
A no-start or stall that comes on with heat and clears when cool is the classic module story. Another important clue is a truck that starts normally when cold but will not restart once the engine is warm - if it fires again only after cooling down, this is likely the culprit. Another way to check the module, which sits on the distributor, is to remove it and inspect it - sometimes it has battery corrosion that needs cleaning up.
Should I replace the coil or distributor too?
Not automatically - if spark returns with a fresh module, the coil and distributor are fine; chase those only if the misfire stays after the module swap.

I'm very happy with the exhaust. It sounds great. I was juggling between this one and Special K's behind the bumper exhaust and I ultimately decided on this one. Installation was easy and the only thing I would recommend is getting some washers because the holes on the flange for the growler are ovaled out to allow for adjusting the fitment. Without the washers the flange nuts were just a bit to small.
I buy almost all of my Honda Acty product through OIWA's website and have never had a complaint. I would highly recommend OIWA's website for any kei truck products.
