Hi All,

first of all I wanted to thank everyone for their efforts in helping me with my tune.

I realize it's not a perfect tune as if you look at the attached log file there is a decent size dip in boost after spoolup and after the boost target has hit. I did Mr. Freds boost control mod and changed WGDC Update delay to 4 and I think this has helped to make the dip smaller. Using the JDM map you can see I'm peaking at 23psi and have a taper to around 18 by redline. I have made no efforts to hold boost up top so far and to be honest I think it might be safer to run less boost up top anyway.

Anyway I haven't been able to get the IDC calc. working properly in Evoscan 2.1 but I'm pretty sure I'm maxing out my factory injectors. I plan on buying bigger injectors within the next week. you guys think I need them right? future plans include either meth inj. and or FP Green

I was also wondering what thoughts are on the boost control based on looking at the WGDC and the correction. I need to read the thread another 2-3 times for it to make more sense to me although I figured those that are more experienced might have some thoughts on how to smooth the boost dip out.

Since I am not really getting a lot of knock due to less aggressive timing my plans are to try and up the boost after the injectors. Should I even bother trying to smooth the boost curve or wait until after the injectors and after I try to turn up the boost?

I am also thinking I am probably a little rich on top and that after upping the boost this area might turn out better and I will probably have to add fuel back down low and mid areas of RPM scale.

Maybe a mods list would help?

Anyway enough rambling for now any input will be appreciated

 

idc = (rpm * ipw) / 1200

You can do this in your Excel sheet by clicking cell AA2 and hitting = then typing F2*Z2/1200. You should get 10.00666667. With that cell still selected, drag the lower right corner all the way down column AA and it will apply that calculation to the rest of the log.

You are hitting 85% IDC at 5700RPM, 90% at 6200RPM, and 100% at 7000RPM.

If you don't have a wideband, you should definitely get one.
If you don't have a high output fuel pump, you could get one.

Your timing is not advanced enough. By 5000RPM you should be able to run 5-6°, and then add another 1° every 500RPM after that.

As far as new injectors... I can't say without seeing AFR or knowing if you have a fuel pump. It wouldn't be a bad idea... I've been running 780's on my stock turbo for a while now, and it makes good power and 75% IDC at 11.0:1 AFR at Redline, 21psi

 

I do run a walbro and column f is the Innovate wideband logged in the spreadsheet

thanks for the reply Shameless

 

Ah, yes.

I would definitely lean it out from 4500RPM to 8000+

You shouldn't have to run richer than 11.5 on 93 octane fuel. You could go as rich as 11.0 at 6500RPM+, but that's even a bit rich in my opinion.

 

I was gonna mention that earlier the problem is I'm running 91 octane and when the maps had the 5-6 degrees timing i got knock counts as high as 4-5 at which point the ecu started pulling timing. I slowly pulled timing out in the 3-6k rpm range to what you see now. I suppose 5 works but 6 definitely causes excessive knock. 5 is 1-2 counts and 6 will trigger 3 plus. If I back the boost down then the timing can go back up. So far seat of the pants tells me that more boost with less timing equals more overall power. Maybe I'm wrong but it sure feels right
