here is the current fuel map im going to try to get pulls with if I shouldnt someone pls let me know, i wont be able to do my pulls till either lunch time or until after work again any advice is greatly appreciated

 

100-200 load seems richer than it should be; are you sure it needs to be that rich to get betwen 12-13 AFR in that area?

 

hey raptord is ur comment for the whole rpm band or just the upper 2250-4000ish?

 

Your fuel map kind of should follow your boost threshold

 

From about 2250/2500 all the way up to 8k+

 

@ 211ratsbud can you pls elaborate a lil on this if possible to make sure i grasp the concept?

thnx for the advice raptord trimming the fuel map, now will post up another one on my lunch thanks for all the help guys really appreciate it

 

hey fellow evom members here are my newest log numbers and fuel map can someone pls give me a lil advice

 

Im not sure I can explain the trend properly, and Im not sure I even gave it the right name. However I drew a line and I believe what im trying to say is that below this line where target boost areas can be reached your fuel map has a trend which is generally leaner. As you increase RPMs you tend to have to increase the rate at which richness happens to some extent. This is an odd scaling i was using, so it led to the hump, but AFR's were consistent.

If one of the guru's has a better way to explain or elaborate on what Im trying to hint at then please do.. Also Raptord noted that youre pretty rich in that area, its hard to see yourself driving in those areas because you normally do pulls going WOT from a given RPM. So those areas kind of get jumped over really fast some times. I brake boost in a low gear to 5- 10 psi paying careful attention to keep the boost consistent the whole way up the RPM.

 

sup guys so im gonna hold off on the tuning gonna get a boost leak tester and a o2 housing then im gonna try again... question my load is going up to 270's would that mean im pushing around the neighborhood of 27psi correct? and if so can that much of boost be ran on 92 oct safely at that level or should i bring it down to around 25, that is what it was prior to the cam install and 4"i/c

 

No, 270 load doesn't mean 27 psi of boost. I'm running about 23 psi and reach 280+ load.

 

ok thanks for the heads up raptord

 

Hey guys update on my learning attempt of tuning lol here are my fuel map, timing map and some log pulls im kinda stumped it idle both high about 2k until it warms up idk y?. then it drives like cr@p at slow speeds if i dont let it warm up im gonna post up some pics of maps and hopefully someone can help me out. How do you tune the 1 n 2nd gear area cuz at times itll go rich. the person who tuned my car also turned off lean spool is this a advantage or disadvantage? I know this is a lot of questions so im gonna be patient hopefully they all get answered is there any room for more timing with my new S2's? i added one degree in the higher rpms, but now looking at a prior cam install timing map and after i think the problem could prob be in the maps due to me rescaling pls lmk... thanks for any help I may get in advance

 

more pics this shows my low coolant temp timing map idk if this will help but maybe lol also added the pre cam timing map

 

First off I think your WOT timing is too low; something like 2 degrees at peak load going up to 9-11 at 7000 would make more sense.

You're ok with lean spool disabled.

 

ok I'll update the timing map with that in mind right now
