I imported my R33 V-Spec from Japan in Dec last year, I am having a few engine tuning (missing, loss of power & extremely rich) issues which I am working thru

I have replaced the usual Plugs, AFM, coil packs (replaced with Okada projects for future tuning), injectors tested & cleaned, manifold gaskets replaced...

Turned the V-Cam system off & still the issue remains, next step is an aftermarket ECU

I pulled the ECU out & opened it & i cannot identify what this is?

it seems to have a "Daughter board" stuck on top of the main board (referred from R33 GTR ECU pics )

Questions,

1. Is this STD?

2. If not STD what make is it?

3. can it be tuned?

4. can it be removed so an aftermarket ECU can be fitted?

as I am new to this any help would be appreciated...

# is 2371024U01 of the front of the ECU case

Then ECU # seems to be correct when referenced by Nissan, it is the "piggy back" daughter board that I think has scrambled

The battery was disconnected when shipped & then a few times after that, possibly could have lost or corrupted memory parameters

From my on-line searches it seems to be an "Techtom" board which is apparently tune-able but I am still trying to find how & what program...

Yes I understand that it is a STD ECU

but when I google R33 GTR ECU this is a STD comp (pic DSC00547)

As mine has a 2nd board (pic 201718) stuck on top, that is what I am trying to find out details about

Email address is on the nistune site,

I didn't imply it is a nistune board.

I said mat at nistune would likely know about other types of boards used before. I'm sure he has pulled apart a shit load of ecus

Ben,

I contacted Matt @ Nistune & he confirmed that it is a TechTom board, thank you for the contact

There are not many people in Australia that can "tune" this board so basically the ECU gets shelved

I am purchasing an Emtron this week so at least there will be unlimited tuning capabilities

I must say that the response time of Matt from Nistune was fantastic...

      They will be (within normal range) and they won't be causing the misfiring.

      Should you buy cheap Chinese tyres?

      By The Bogan · Posted

      Chinese parts can be good, it's all in the quality assurance, and materials, but, that costs more, but, typically not alot more, it is up to the customer who is getting the parts made, some are happy to pay more for quality good QA and materials because the savings are in the cheap labour costs, so they can sell a quality product at a lower price point, other customers who are getting parts made give no farks and want their products to be as cheap as possible for maximum profit, so minimal QA and average materials  Hence why some Chinese parts are crap, whilst other are good Much like parts and other stuff made in different countries around the world, including "made in Australia", "made in Japan", "made in 'Merica" branded gear

      Agree with Bogan bloke above. I like running quality tyres on my street driven cars. Wife's daily as well as my daily have Michelin PS4, good tyre that does everything you'd expect without fuss and reasonably priced for popular sizes that aren't enormous. Skyline had Yokohama on it for many years but have recently fitted zestino tyres. Just did a quick Google and they're actually Chinese made (jap designed apparently). Surprisingly they grip really well, wet and dry and haven't died, YET. Obviously on the higher end of CCP tyres but still China nonetheless.
