dont most ppl tune for fuel first, then timing?

 

Watch both. But usually I keep the timing very conservative first and try to hit my target AFR. You still have to keep an eye on timing. Adjusting timing and alter AFR too.

 

yup that worked got the flash on the car and got the logs now I'm gonna try to get a better tune . so when I WOT I hear like a high whine noise is that knock? I looked at the logs and I barely encountered knock could this noise be something else?

only when I'm in wot does the noise show up, nothing up to 10-15 just when I get into wot and its around 20psi even at low RPMs

 

I would us tephra v7 mod and just run a little bit more aggressive timing over stock and like most every body else said just go slow and make sure that you log all the important things like knock sum, afr etc.

 

The noise that you are probably hearing might be a boost leak. i would do a boost leak test on the car just to make sure there are no leaks. if that was what you are hearing before you do anything crazy with the timing just make sure that the fueling is safe. It is always saffer to run the car 10.5 afr the 12.4. Just take things slow and make sure everything is on point and perfect.

 

Does a boost leak sound like a whistle sort of noise? can anybody give me an idea on how a boost leak sounds like? im gonna go and recheck all my couplers tmrw see if that fixes the problem... The sound doesnt become apparent until I WOT I drove around at 10-15 lbs with no problem, then when i start to give it gas that is when the sound comes back ill see if i can take video and hopefully the noise I hear is recorded

 

yes, a boost leak at a coupler or at your Jpipe gasket will make a shrilly whistly noise at higher boost levels.

do a boost leak test, it is a must do part of tuning

 

got the boost leak fixed, my buddy wanted to help work on the evo and he tightened the licp guess where the leak was?? lol the j pipe to licp was almost off last time i let someone work on my car lol

 

what type of file do i change my .csv files to so i can upload them? i cant get my last data logs uploaded so you guys can check them out and lmk how im doing on the tune

 

.txt will work

 

Well mine is always plugged in but if I want to read my ECU and I imagine flash. I have uplug my cable then turned to on ( not engine on ) then plug in my ODBII cable. Then ecuflash will read. If I turn the car of then just to on and the cable is always plugged in it will give me an error and wont read.

 

here are my newest datalogs guys only went to 4-5k for the first pulls to see how the new cams affect the tune. looks like there is a lil bit of knock

 

15 afr with 20lbs of boost being built? you better redo your fuel map asap.

 

ya im looking at that right now also they are way out of the target range, so since the they are at 15 i need to add fuel correct?

and if thats the case ill need bigger injectors or lower boost to compensate not having bigger injectors right?

 

lots of fuel yes, and you also need to log load or you are tuning blind for the most part

lol nevermind, had to scroll way to the right i see the load now. but yes add lots of fuel much sooner.

the crossover needs to turn rich much sooner then it is now.
