i got a 50 shot 5177 2 nozzles up through the filter. 36lb injectors with correct ifr. min. inj. pw=.79

wot last about 3-5 seconds. 65* outside today at 3pm.

na afr=11.4 no kr.

n20 afr= 12.3-13.1 with kr up to 3.9*
ltft never goes past 3.9 for bank 1.
iat starts at 72* and goes down to 55*

i've still having issues with a rich decel but i'm going to live with it. i just want to spray!!!!!!
i've been told by a reputable tuner that the 36lb injectors don't really need any tuning besides the ifr table.
1. am i having more problems than there should be?
2. what should my iat be during spray?
3. if i move up to a 100 shot, and my iat goes lower, will that tell the pcm to add more fuel?

 

4 degrees of knock is a significant amount, and 13 afr is too lean.

 

IMO you need to tune for spray to be safe for you

 

i'm not trying to argue with your suggestions but the car seems to pull good with ifr and min inj pw changed minus the lean ifr.
most post i've read have been just changing ifr for injectors.
i ran a stock tune with just the ifr change and was seeing kr to 9* on light driving. when my min inj pw was set to .79, i would not see kr past 5* in low rpm/throttle.

are the problems that i'm having normal for an injector change or might i have other things wrong.

i have hpt but don't no which tables and what direction to take them. a tuner has told me that i shouldn't even have to tune ve or maf for just an injector mod. and i agree since this is on a 50 shot. am i wrong?

 

There should be no knock retard what so ever.. does it spike up and then fall off real quick, or does it increase as your rpm's increase?

 

I had a 5177 kit and a mail order tune, ran it with no jets and the car LOVED it!!

 

You aren't rich, you're lean. 11.5 is safe on spray.

 

i was having a separate problem with rich decel. sorry for the confusing wording.

the afr numbers posted are on accel.

1. new question: i have a wb and hpt. can i tune the ve by looking at my log and identifying where the lean and rich spots are then locate the corresponding cell in the ve table and add ve to add fuel and subtract ve to decrease fuel in the cells with bad looking afr and knock?

2. old question: is it likely that i'm running lean on n20 since its a 50 shot thus not enough cold spray is getting to the maf and iat at a cold temp.
my iat was only seeing 55* on n20 which seems low? especially since i just came from a night drive where my iat was seeing 56* from the outside air. so i'm concluding that my 50 shot n20 is just spraying more air but not cold air???!?!?!?! my na tune looks fine at wot since my afr is 11.4-12.2.
