Lol. Yeah it says 200 for nistune. But only for q45 throttle body install.

Or u could just Connect to consult and try a throttle sweep to see if it is working correctly.

Then connect a wideband sensor and start the car to monitor the afr.

Because nistune uses a airflow meter there shouldnt be any issue but always better to check.

If however u had an ecu with a map sensor then a retune would be necessary

Yeah i thought it all sounded a bit dodgy, came across that piece of 'info' in a forum, and as we all know what is said in forums is true :happy:

It all seems to work just fine, the 'TPS idle' lights up when idling but i just cant get the idle as smooth as i want it to, though im running 850cc injectors so i might not get it just right IMO.

Its been tempting to run Link (or Vipec, same thing), Haltec or any other ECU so that i can get rid of the AFM but i kind of like Nistune, not that big but a great option if youre happy with using a AFM. Actually ran 2x Q45 AFMs last year in my RB31/26DETT, running them through a SAFC let me get past the one-afm-only restriction ;) That engine was a bit much, I gave it a basic tuning on the streets, anything else was impossible but now im back with a more street-happy stocker so hopefully i wouldnt need to tune it on a dyno first thing.

      R32 GTS (RB20DE) clogged cat

      By GabsReDeal · Posted

      Hey everyone, This is my first post apart of the introduction. I tried searching a bit on the forum but couldn't really get a straight answer. I got the car to my mechanic as I felt it being weak. It seems that it was missing on two cylinders due to the injectors. I had all my injectors clean and the car runs much better. The mechanic also confirmed my suspicions that the cat is clogged and needs to be tackled asap. The cat rattles a bit and the hot exhaust warning frequently lights up when driving after getting the injectors clean. In my introduction I was asked about what modification I might be interested in and mentioned a cat delete. From what I was told, this is not really beneficial on the RB20DE and there are more cons than pros.  Could perhaps anyone give some suggestions on what the best course of action would be since the current cat is toast and needs to be removed/replaced anyway? I can also sometimes smell a strong smell of fuel, but I'm not sure if this is related.

      255 can't go wrong with the price.

      When I was replacing my pump due to being stranded in the wrong state, I went with the Deatschwerks 320lph kit. It is a direct plug in to the stock wires, harness, everything. It comes with a plug... but you can plug the OEM plug directly into this thing. https://justjap.com/products/deatschwerks-dw300-fuel-pump-nissan-s13-silvia-r32-r33-r34-skyline-c34-stagea?currency=AUD Downside: Won't actually flow that much on boost if you want to push it on E85, but it's comparable to the 040/255 etc. Little more actually.

      I dunno what the "best" one is....but when my 040 died late last year, after about 20 years of screaming service....I put in a 255. Like any such thing, you have to finagle it a little bit - it's not a no-brain swap. But it's not hard.
