Cobb soon to release load cap defeat!

[Jchouin1]

I read some wonderful news on the Cobb forum that they are currently testing additional tables for ATR, which will be Calc. Load A & B, which will allow for accurate fueling beyond the cap. It appears you will be able to request a load beyond your cap (different between cars/climates), and will be logged as a % of requested load. I personally am super geeked about this, because I clip my load cap @17psi! Get excited ladies and gents. I'm already daydreaming about 3 things that these additional tables will provide me:
1. Proper MAF scaling (currently scaled down to try to stay under cap)
2. Correct AFR under high boost (currently gets lean with initial boost, and then gets too rich in upper rpm's, all due to clipped load cap)
3. 23psi (AFR's not desirable beyond 17psi without the MAF/commanded eq trick, which is effective but sketchy! I want booooooooooost!)

Me thinks this will help push AP guys to that 400whp mark so we can go out and play with the SB folk

Great news for your mod level with a bigger turbo, etc. Please let's not consider encouraging guys to run 23 psi sustained on a K04 turbo, and I don't think that was your intent.

Just in case a modestly modded reader with the K04 in place should read this, that little turbo turns into a pure heat generating hair dryer at 18 psi at any rpm above 6,000 when under load in the higher gears and will burn its self up PDQ, IMHO.

You guys are badass! I ordered it as soon as I got the newsletter! I'm sweating...time to do work!

So I ran my first datalog with no load cap, and to my delight, no clipping and calc load over 200! My car clipped at 185-187, so this is sweet. At 17psi, I hit 206 calc load, and fuel was dead on nuts. This is great stuff!

Nice... what other mods do you have?

Just did a datalog as well, I forgot to put calc. load on the datalog list (doh!) I didn't hit full boost, only got up to 17 then tapered down to mid 16's and I should be hitting 18, but the car is running great. And what I really like is, my fuel pressure looks alot better than it did before. I had thought maybe I needed internals asap (which I'm still going to do when I get the money).

On a side note, should I be concerned that I'm not holding higher boost consistently? I know there are all kinds of factors. Could the recent addition of my FMIC be the culprit? If so whats the fix

Check all your clamps, tighten. I have noticed recently that I've gone from spiking at 20-20.5 to spiking around 19-19.5 and tapering faster than usual. I've had my FMIC on for about 9 months so it's time to check and retighten all the clamps I guess.

Did you customize the new updated load cap OTS map? I thought that the only way you'll notice a difference in performance is by tuning the load cap on the new OTS and not by just flashing the updated OTS map with no tuning.

A little more playing around in ATR yields load in the 220's, but my IWG with 8psi spring is too light to hold high boost to redline. I should have a 14psi IWG very soon, so I'll start playing with higher load requests. This is great though! I set it at 2.2, and I hit the target, just can't hold it. The new IWG should be the cure, because you can't hold over 2x the rated WG at redline. I should have ordered the turbo originally with the 14psi spring to begin with, but I was sitll flustered from blowing the engine! haha

I noticed the same thing until the day I launched my top pipe into the hood when a coupler let go! Giving them a once over is a great idea
