well i have a problem on start up in colder wheather it will go rich i think when ins in open loop. latley on 1st start up it will die like it did in the log and when i restart it i gotta give it a lil gas then it smooths out. also when driving some times the idle will fall when i push the clutch in and go in to neutral. also it likes to fall or dip when im trying to park. this is the only problems i have with the car, just some minor idle things i would like to get rid of.
in the log when i 1st started it it stalled. restarted with a lil help, i let it warm up then i turned the wheel some to watch iac steps, then i was doing some revs, then i turned it off then restarted.

I can probably get this pretty good but I will need to start over. What kind of car and year and what are all your mods you have? By the tune you have it should rev pretty high on startup so something is all out of whack.

fyi i tried a new truck pcv valve and i think that might have been my problem, it dosent flow enough air so i put theold ond back in and it starts great. so i guess if i want to use this new valve i need to increase air flow.

I tried to look at you log but I can't get it to open right. Are you still running the stock injectors? From how much airflow you are putting to it on startup it makes me think the tune is way too rich. I'm still looking at it though

what brand of MAF are you running? I have a tune for you that I think may work pretty good but I need to know the exact maf you have so I can set the tables.

well I redone the tune somewhat close to the specs of mine. Two things will take a little work, the injector flow rates and MAF settings. in the mean time if you want to flash this in and see what it does. I'll do some more searching for some flow rate tables. I have it set a little more than mine since I have the red top 36 pounders. Also depending on what kind of maf you have I may have to do some changing on that. I couldn't use my tables since I have a stock maf. So let me know what kind of maf it is and I will see if I can get it closer.. Here is the tune so far.

one thing I would recommend is selling the large maf and getting a stocker to put back on. Seems the big MAF causes alot of tuning troubles and doesn't really give any gains. I hear the stock maf can support 500 hp with no problems. Just something to think about.
