that is strange because my s14 does get lean when i start to build boost then eventually gets rich after a few seconds but only when i have my o2 sensor feed turned on, thus ive been driving around with my o2 sensor turned off and my AF ration is where i like it. glad you got it all figured out tho

well i moved my ground wire for my maf and put a ground wire for the engine to the chasis on the turbo side and everything was fine till i went out and drove it and now the car idle high the tune is spot on just idles high.. winter is coming and im about to pack the car up and store for the winter. ...

i got my car out today and recorded a small log of the issue with my AF ratio changing when i turn my headlights on. i found that the injection timing is changing the most and the mafs is changing some but not much at all. i have not changed anything yet with the bov or the valve cover vent hose jus...

Ok so I'll go over my grounds and figure out a way to recirculate my bov and see what that does. Thanks for all the input it's been real headache before the tuning even began.

Would it really be a boost leak? I havent had any issues under boost my AF ratio is right on it's just when I idle its lean. Normal driving is ok too just my idle is leaner than I think it should be. Im going to move my ground wire for my maf and see if it changes anything when I turn the headlights...

ok i will recirculate the bov when i get the parts to do so. what do you suggest i do about the vent for the valve cover right now i just have the hose that was on there from factory for the time being. should i just put a breather/filter on it or should i route it into the intake pipe in front of t...

My tune was perfect till I put the top mount on I did nothing with timing or tps and yes i hit the burn to rom.

I'm having issues with my tune after installing my new turbonetics topmount turbo. the maf is as far away from the turbo as i can get it which is about 15 inches away theres only one bend in the pipe and thats only a slight bend right at the end of the pipe where it meets the turbo inlet. ive notice...

very good idea. perhaps next time it throws a fit i'll jiggle the harness and connector and see what happens.
thanks for the advice

I'm having a problem with my z32 maf acting up at times seems to only act up when i drive down the highway at constant speed say 70 mph for 30 mins or so... then when i get off the highway and let the car idle for a little bit it runs rich then lean idle is very unstable then when i go to drive off ...

ah ok i have it now. i was under the assumption that you had to adjust the multiplier for lower loads and RPM's. much better now. thanks ALOT!!

ok i have issues with my injector multiplier ive tried several different times to get it right and i still cant get it where it should be. i have a s14 sr20det with Brian Crower stage 3 272/272 cams, springs and retainers i have Jecs 700cc injectors with a z32 mafs. my issue is when i set my raw val...

well i think i got somewhere tonight. i adjust my Kconstant again and then my latency once i had the Kconstant close and it seems to be doing ok my timing is back to 15 degrees. hopefully the next step is a base tune then a dyno tune.

My a/f ratio is good it fluctuates from 14.5 to 15. I tried adjusting my injector multiplier to see if my timing would come down any and it didn't nor did adjusting latency.

here is my data log
