Are these Air/Fuel Ratios anything to worry about?

[«Cyph3r»]

Hi boys and girls,

Just wondering whether these air/fuel ratios on my dyno printout are anything to worry about. Car is RB25det engined 33 with hks 3037s turbo, hks 264deg cams standard internals, running on 98 octane pump fuel.

Sorry about the blurry photo of the dyno sheet.

Cheers

Hi Cyph, goes a bit rich at 110 kph, that why the power flattens off a little. Gets as rich as 11.4 at 130 kph. If I was being hyper critical, I'd lean it off a little from 100 kph to 160 kph. You should pick up a few horsepower and take those dips out at 125 kph and 145 kph.

Just make sure the lessening of the richness past 170 kph is not the injectors or fuel pump running out of capacity.

Hope that helps

Thanks for the advice sydneykid but i'll need to invest in a powerfc before i can get it retuned unless someone finally has the fcon tuning software in qld? Pretty sure the injectors would be nowhere near 100% duty cycle as they are 800cc items and the fuel pump is very noisy but i guess it could be struggling?? Just making sure that its not leaning out and damaging things.

lol. its more of a rice boy car. only 220rwkw and more work on body and stereo than motor. nice having boost at 2800rpm though for a change

What power you getting ? 220rwkw? What computer you running then?

hi robo,

Actually the 220rwkw is from my toyota (stock 1jz-gte [tt] with power fc + cat back exhaust).

My nissan is running a hks fcon v and i am unable to get it tuned in qld afaik.

I think its tuned pretty badly atm as its very unresponsive and doesn't make anywhere near its potential power, only 350rwhp or so at 1.2bar

I'm too scared to listen to anyone who would tell them, i wish i new all this before.. :|

Doesn't he drive his girlfriends auto r33 or his 20b cosmo with the GT3540?

I drive the mark II. Wimmer drives his gf's black auto 33 with rotormax stickers (mel her name is afaik) and i heard he sold the cosmo cos no one else liked it and though it was cool 8) He also drives an oldish 3 series beemer with wim02 plates
