Mana, so you have had luck with the gear specific boost? Last night I played with all the values and could not change boost at all. No gear showed any signs of boost reduction or increase. You should definitely play around with it on your car and see what you can come up with. This is a feature I definitely would like to have.

I will, but I don't know if I will get into it until later on this week. Change all the values to 300... I bet you'll notice a change in boost

Yes it is possible but I don't believe the NGC calculates this. From my personal experience, the boost by gear funtion doesn't work, in the processor code I am using. It may work well in the others. I will try to do a quick test tonight and find out, and if I find that it is usable in any of the processor codes that I test, I will definitely share the information.

Set all the cells to 300... You'll notice it

Sour, lets us know what you find!

Mana, I'll try that out!

It will be >10 psi... I was riding on spring pressure before. So I am not sure exactly what pressure it is. Slowly turn it up. I think second gear is going to need to be between 400 and 600.... Not sure where yet (which cell second gear is)... I think first gear is cell 0 and part of 1... Not sure after that.

My car is tuned and ready for testing,,, in the morning.

quick rundown on test tune:
stock stage 3 turbo and wastegate
stage 3 turbocharger settings,
stage 2 fuel settings,
stage 3 spark settings

This should be a fairly simple test. I used the 05 code. 3 tunes. One with no torque reductions, one with gear based reduction where all cells are set to less than 250, and one with speed based reduction where all cells are less than 250. Once this is tested I will try the same settings in the 04 code. See ya in the morning!!!

FYI Gear based boost set at 250 is going to give you just WGA spring pressure...

Yep, that's what I wanted, and thats close to what I got. I started with the gear based reduction because it's what I wanted to really test. Read the next part carefully because you rarely see this on the forums,I was wrong. I'm not sure what happened last time I tested it but it didn't seem to work. Maybe my numbers were too high. It did seem to spike pretty bad when boost first came on though. The boost would climb to 15-17 then bring itself back down to 10-11. Stage 3 wastegate is 8 from what I gather so it was alittle higher WGA spring pressure. It does seem to work though. I didn't get to really test it too much cause I was on my way to work and its pouring here. Now all we need to figure out where the table cells begin and end. I will correct my mistake in the wiki as soon as this is posted.

This is a great example for why you shouldn't believe everything you read on the forums. I tested this before, it didn't seem to work. I put that information on here and people questioned what I did so I retested and it does work. What would of happened if nobody questioned me?? Take everything you read on the forums with a grain of salt.

Well, that's good to hear!

I'm going to play with this more today and see what I can come up with. I'll let you guys know what my results are...

Added 2 more pages:

Power Enrichment Above Stoich FA Ratio - SCT SRT Wiki
Stoich FA Ratio - SCT SRT Wiki
(feel free to fix these if they are wrong)

I also created a new calculator to aid in editing the Power Enrichment over Stoich page:

Target AFR Calculator


Lets get some more pages and info in this thing!

We could use:

A Basic WOT tuning page
Scaling for a 3bar MAP



Thanks Sour Kraut for fixing the Gear Dependent Boost page!

I like the calculator. Can you set it up to have a defualt Stoic? The actual stoic (being used) should be .0695037 (14.39:1), and having that in there would make the calculator really fast to use. Thanks!

I just figured out a really easy way to figure out what cell is what on the boost by gear table. I played with my datalogger a lot tonight and found out a bunch of useful tools. I can figure it out pretty damn easy and then post up my results. It will be this weekend though before I have more time to play.

Just made the update, let me know how that works. If you have other requests for anything else let me know
