i just swapped an rb20det into my s13 chassis and got it running today, it runs super rich as is. i have an apexi safc neo hooked up and yes i know that is not enough for tuning. my set up is a z32 maf/afm, walbro 255lph fuel pump, hks 2535 turbo, and sard 550cc injectors. stand alone would be nice but i would prefer to do something more affordable. what options and advice can i have for tuning?

is there any reputable places that do remaps i can send my ecu to, if not i'll just have to save for a stand alone. i will look more into nistune, has anyone ever heard of vipec, a guy locally recomended that to me, im sure you all have heard of his car its the rb26 gtr powered bmw e30.

I see you are in the states.

Nistune are local to Australia. Taking the factory ECU and adding a programmable ROM. A great option for your current level of mods.

Vipec (Link) is a New Zealand product (correct?). They are supposed to be great quality products, but any ECU option is only as good as your tuner. If your workshop of choice is confident in tuning them then go for it. The cost could be twice that of the Nistune, but they are about as easy to tune as the other. (From what I am told).

There are a few threads around here on both the Vipec and Nistune. And plenty of experienced tuners who post in this section.

Best of luck in your choice.

I have a Power FC in my (RB20 Powered) car, but if I had the choice to spend the money now and the Vipec was available when I first went to a full A/M ecu, then I would probably have a Vipec in my car.

the local tuner around here used it for the first time and got that e30 gtr to run good within a half hour, apparently the tuner could not get a good tune, or the car to even run right with aem ems. i went to a drift event today and talked to other rb owners and i was talking about full standalone ems and i guess this guy can remap ecu's and get them to run really close to perfect, he also specializes with rb20 tunes. im gonna try and find him on a few forums, i guess he is carl h. if you've ever heard of him

      A 1.5 way is a 2 way. It is just a 2 way with a less aggressive ramp on overrun.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      The ABS and/or TCS being missing/broken will not cause the engine to misbehave. It just casues CEL to come on and annoy you. The CEL is useless if it is always on, so you have to do the things you have to do to get rid of it, so it can be useful. Being a Stag ECU, then yes, it will not expect TCS to be present. But it will expect ABS to be present and working. You will need to either make the ABS CU talk to the ECU (don't ask me what that will take on an NA R34), and make sure the hardware is working....or, you just need to blank it out in Nistune. Do not persist with the stock ECU. You will just have problems. Gte it Nistuned. Start from there. DO YOU HAVE A BOOST SENSOR? The ECU's boost sensor that it. It is connected to the loom at the rear of the coil cover. Usually rides on the firewall on an R34, but is usually bolted down to a bracket along with all the other crap at the back of the coil cover when a Neo is dropped into another car. If you do not have it, the ECU will shit the bed. So, do you have one?

      So sadly the fuel pump etc was not it. The pump and filter is new and it is still cutting around 4000 rpm. A read something about ABS/TCS (engine is from stagea and ECU too so no TCS) and i dont know for 100% that my car has ABS. It has ABS "cube" in engine bay but i dont think it works(or at least from my braking experience). Can be something like that?  I will be driving the car next week to Nistune tuner to properly see what is wrong...

      the Tomei LSD fluid with lsd kit. frustrated that it was shaking the car to crap and affecting everything else negatively, I pulled the diff last night, and removed the lsd carrier, could not find anything wrong, however it seem to be 100 locked up acceleration, and deacceleration, wondering if they sent me a 2 way not a 1.5??  either way I installed the stock open carrier back in place. test drove everything smooth as butter again. no shake, shutter, random, what felt like clutch slip and grab or drive shaft play, etc. something differently wrong in side the lsd. I might bother taking it apart (if possible) to figure out what's going on inside this carrier, as bought too long ago to return.  only draw back is its back to a one wheel wonder.
