Super duper LEAN

[sunnys14]

I am having a very odd problem...

I have to add about 25% fuel at idle when cold to get a stable idle and have to add 50% fuel at idle when warmed up! Getting weird lean misfires when warmed up also. Heres my setup:

555cc Sard injectorsz32mafEnthalpy ecuRewired fuel pumpT28

Before i had an odd problem with the car running extremely rich where i had to subtract 30% fuel at idle, now the car is running the exact opposite after I changed my plugs and coolant temp sensor. New wideband sensor so I know that the wideband isn't taking a crap on me.

I also checked for boost leaks, FPR vacuum line, ripped couplers and what not... I'm pulling 22 inches of vacuum at idle.

Its supposed to be rich on start up, but you shouldn't have to add or subtract fuel. Why are you using a SAFC when you have a ECU tune? Especially since you have more problems with a KAT then anyone I've ever seen.

When I had that problem it was cause my in and out settings where ****ed up. I also had a tuned ECU.

So one day at a stop sign it hit me, I changed the in out settings, and everything fixed it self.

Another thing, whats up with that avatar?

u know i just thought about that, would the best way to check for a ripped coupler be soapy water?

[Craving4Boost]

Yeah we really gotta hook up my consult board and log the pulsewidth of your injectors and see how hard or lazy they're working with this tune. In conclusion....I'd say ghosts...

[sunnys14]

yeah steven, send me your consult board

gotta use the SAFC to fine tune the fuel maps. Apparently i had to add 12% of fuel above 3800 to redline to get a 11.5 afr. i switched in and out settings from 2-2 to 5-5, still the same

whats wrong with the avatar?

[WDRacing]

is it you...are you a chick? if not change it cause it makes everyone think you have tits. Also, you're adding way more then 12%...I think its operator error 100% since you've had so many problems in the past. Every other day it's..I blew this up, or I went ahead id destroyed yet another KA from the junkyard....

Tell me I'm wrong?

[sunnys14]

the avatar is my sponsor, i cant change it

[WDRacing]

Tell him/her to get a new pic...sponmsors have a name, I aint buying that BS...don't make me change it.

[sunnys14]

I didn't know it was against forum rules to have a picture of my GF as my avatar. I've had that picture for over 2 years and no one has ever said anything about it.

Why do I sense hostility from you towards me all of a sudden WD?

[Jookmasta]

u'll have to excuse WD. he's yearly subscription to rapidshare is ending soon and he's having trouble finding more space on his comp for the pron. nonetheless, you really have had that pic for years and i can't blame ya for having it there. if only i could have such an awesome sponsor, i'd change mine too lol.

WD, i got some links u might be interested in........................

Meh, I drink to much obviously...lol

[Structure240sx]

i used to have to add 50% fuel to my idle with my jwt ecu always or it would die o ut from being so lean.

had to add on the hi map also about 25% but i figured that was from kinda maxing it out

[Jookmasta]

i think i must be drinking too much cuz i just saw a post by structure...................

Do voltage drop test. Loose gorund abd ground somewhere. Car went from missing to running perfect. 1 ground was loose the other was against paint so no ground...Also just because your wideband is new doesn't mean it is good...

[Florida240sx]

I think we are tied in engine problems on ka-t.I'm on my 6th I think...

[WDRacing]

Exactly why I'm going Hybrid man...

[sunnys14]

I blow more engines more than I change oil, but something about KA-T's just keeps on bringing me back.

[Florida240sx]

The snappy torque and people asking you what engine you have swapped and then they are confused when you say no?
