so i ran some SR20's tonight

[sunnys14]

The only RB that came with ITBs was the RB26DETT.

The only SR that came with ITBs was the AWD SR20DET out of the Pulsar GTi-R

PS: i started in 2nd, 30mph-130mph, enthalpy tune could use a lil fine tuning

[spooled240]

man sunny i would love to race you, i don't think our output is too far apart. you have 9:1 cr @ 11psi on a t28 and I have 9.5:1 @ 9psi on a t3/t4..your probably faster with all the supporting mods like cams and bigger tires, etc..but maybe on a roll-on??

[sunnys14]

sure im down

[Florida240sx]

Sure your wideband is good and no exhaust leaks? Or did you change your turbo? His tune was good for me at 19psi. What was the temp outside that affected my a/f ratio someitmes it was perfect othertiems it was rich. I calibrate it every 3days.

[spooled240]

shouldn't the air-temp sensor adjust for that? Probably not enough..?

man, i need to dyno my car as soon as I get all my shyt back together, smog checks SUCK!

[sunnys14]

I had Enthalpy send me another tune because my last tune was running so lean, this time he sent me a better tune that added fuel, nothing a lil SAFC cant fix though. Better than having to add 15% across high map, i just did -5% across high map to get 11.5 afr's.

My PLX unit doesn't need calibration, the wideband sensor is new, just replaced 3k miles ago.

[neverlift]

its ALWAYS safer to remove fuel with an afc rather than adding, IMO. Advancing in the map does just that but on both maps(fuel/timing)

PLX ftmfw send that enthalpy back one more time to get the 5% removed via the tune, use afc for even more fine tuning...

tan leather FTW!

Fux Yeah!!!!! WOoT Thought I was the only one...

[spooled240]

^do you enjoy luxury? lol

[Florida240sx]

Your unit does have calibration? Both of my widebands have calibration on them. NGK and innovativeSuppose ot have outside in the air let it warm up for about 3minutes then one I ground the sensor via a wire in the harness, or other I have a dial I turn till it's gives a reading.

[sunnys14]

PLX m300, no calibration needed for this wideband thats why I like it.

[neverlift]

same here with the plx smafr... main reason I chose plx, that and I'm too lazy to pull the sensor every couple days....

[Craving4Boost]

your car was pretty fun yesterday man. But try not to boost so much when the fuel line is on E!

[sunnys14]

whatever, i got enough gas haha.

you like boost?

[spooled240]

boost is most fun on an empty tank, the car's way lighter!!savor the moment..

[Florida240sx]

Not too empty where you run out of gas and go lean...
