Consumer Warning: Do not buy the ISIS Z32 Maf!

[Cooked Rice]

Alright so a few of you know that there is a new MAF on the market for Nissan folks. See link:

Enjuku is ISIS's main dealer at the moment.

I ordered one about a month ago. Enjuku said they sold hundreds, none came back, no issues. I took their word on it, I mean Enjuku is a good company.

It arrived about a week later, and I installed it on my KA-T with a SAFC NEO as a airflow converter. She didn't fire up. Tried a bunch of different settings, but no luck. I contacted Enjuku racing and they sent me a replacement right away, great!

2nd ISIS MAF arrives another week later. This time she fires up. Alright awesome. So the last week or so has been stupid cold. I decide to run the S13 up to full operating temp, as it's parked for winter. I noticed as the engine started warming up, the idle got shittier as it went. Once it was up to full temp, the engine was barely able to stay idling. The electric fans kicked in, the engine got very erratic and just stalled out. Turned the car back on, bad idle, still...

I let the car cool down, and turned it back on, idle was ok, then it warmed up again, and I was faced with the same damn issue. I noticed the AFRs were too lean.

I found the issue was that the ISIS maf has a lower voltage output to the ECU that it really should. And that any fluctuations in the 12V it needs to operate sets it off and due to poor circuitry inside it is unable to compensate.

Over the course of a couple days I was very puzzled. I tried looking to see if I could find any of these 100+ people Enjuku has sold this MAF to with NO luck. I posted on Zilvia, and no one had used one. Which is VERY awkward since Enjuku sells a lot of their product on that forum.

I discovered that this MAF is a cheesy mass produced made in china piece o shit. The company that makes these also make hundreds of other crappy knock off mafs as well.

I went to see Shoaib@JDM Source on Friday. He had one last Genuine Nissan Z32 MAF kicking around and I snatched it. I immediately noticed the hot wire elements in the Genuine Nissan maf and the ISIS maf were DIFFERENT.

Today I got around to putting the genuine nissan MAF in, and she runs perfect. There were none of the problems I had with the ISIS.

I contacted Enjuku today about my findings and hope they do the right thing. Give people their money back who have bought one. And pull the item from their catalog.

So, AVOID THIS PRODUCT!

Glad I decided to get a real Z32 MAF from JDM Source.

Like i say, you get what you pay for. I would prefer OEM, they always work haha.

just how much are we talking about for these cheapies? I mean an N62 isn't that hard to find is it? And they are usually like $100

170US. I purchased one as I wanted a new maf vs a used. But it isn't even a good copy of the actual nissan maf, as i discovered.

Djetro is GREAT, but the L-Jetro is good too, i use it with a z32 maf and it works awesome. Cant wait to push the limits next year, if my drift/track bitch s13 doesnt take up too much money/time

so what do you think about this isis coilovers???? would they be worth it for $679?? (yes i know you pay for what you get)

[sr20s14zenki]

Not a chance man, i would buy a used set of name brand coilovers before i buy cheap ebay junk.

I just got a set of Tein HA for my s13 for 550$
