sluggish throttle on low RPMS

[gbaz77]

hey guys,

just wondering if there is some adjustment needed somewhere or if its just the fact that my car is untuned.

at low rpms, it feels like the throttle wont climb anywhere near as fast as a normal car. it is running rich, and i figured this could be the cause.

is there a quick adjusment/fix for this? i AM planning on getting a tune within the next week or so, just wondering if this sounds like something that shouldnt happen even without a tune.

are you refering to ' off boost ' driving?? cuz my rb20 acts this way too. I just ordered a Nismo FPR, cuz i know i am running rich even with advanced timing.

i think i need an adjustable fpr as well. its running rich. it seems to almost choke on the fuel at lower rpms, which is why i think it wont rev fast, or at normal speeds until it gets past 3krpm or so.

Ignition timing is first check,10 dgerees btdc @ idle has to increse with rpm,check nvcs operation,off @ idle on @ tip in throttle approx 1000rpm,if not verify cam timing.

lmao.. yess FPR ftw... shall solve your issues.. gosh you peoples need to make this your first mod! it gives the most bang for the buck!

what is NVCS and can you explain that check a little more thoroughly?? and i thought the timing was supposed to be set to 15 degrees on rb20dets??!
