Rb20 Starting And Throttle Response Help...

I have a 89 skyline gts-t. I drove it for a couple weeks and i was having problems with what seemed to be fuel cutting around 4200 rpms. So i took the computer out and it reads MEC-R109 also has a chip in it. Well now the first 4 to 5 starts it starts up and dies. Then after that it stays running but poorly. It has no throttle response, it acts like it is hitting a rev limiter around 3 grand. So i unplugged the maf sensor and it will not start without it. When i get it running i can unplug the tps and it runs the same as well as the maf sensor as well nothing changes but maybe 200 rpms and it goes up thats all. The little red led light in the computer blinks as well as the exhaust temp gauge on the dash. They just keep blinking all the time and will not throw a code. I just dont know what else to do I looked at my wiring and it all seems to be in tact. Any advice would greatly be appreciated.

If I had another one I would, I live in Ohio so it's not the easiest thing for me to get but I can buy another one and wait for it and try it. Also should i get another one with the same exact numbers on it? I was really hoping it wasn't the ecu. But i'm also new the Skyline scene.

Nah, get an ECU for RB20DET (standard), manual I presume?

Quick google search:

Do you guys have Japanese spares wreckers? If not, maybe import one from Yahoo Auctions Japan (via a third party shipper, in Aus we have Jesse Streeter and Import Monster to name a couple).

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
