Yeah I learned this the hard way. For the record, the last log is entire table times 1.10, and KMFIOP scaled with the excel calculator and load axis modified. After trying a few more things with KMFIRL (shifted tables over 1 column like nyet said), I like the way the latest revision feels to drive. But realisitically I'm out of fuel injector duty cycle. The stock hardware dream is over daz...I'm going to need those fuel injectors.

hmm was saying just do that to IOP.

for KFMIRL you only really need to raise the last two or three columns, and you can leave the axis alone...

So I've decided the KMFIRL/KMFIRL modifications must wait. I like how these tables open up more power, but I simply can't fuel the car beyond 4000rpm. I went back to the drawing board today and came up with a new revision that has less boost (stock IRL/IOP), but more timing.

I did a log, and I noticed my requested load is quite a bit lower than my specified load until it starts to ramp down (following LDRXN profile) at 5500rpm. Is this a result of HBN or some other function? Posting a log and the graph showing what I'm seeing. My IDC is managable now, I think I can afford a bit more push in the area where requested doesn't match specified.

Thanks nyet.

I put the variables into my log config. I'll re-log in the morning and post the csv. I have all of these: mifa, miist, misol, miszul.

Typo on ldlrts? My config detects ldrlts and ldrlms. Engine and turbo protection functions?

Your mifa (reqested torque) is significantly below driver requested torque (mrfa). You'll need to increase the last load column of IOP so that it generates a torque request high enough to output a load request (from IRL) that meets rlmax, or make sure IRL requests a load that meets rlmax at 75ish torque and above.

Not sure how to explain this more clearly, it is kind of confusing. I have reworded the s4wiki tuning page some.. you can review it again if you like.

HBN looks fine.

mizul (torque intervention limit by timing cut) looks fine.

The easiest thing to do is just increase the last column of IOP to 99%... I have had good success with the IOP tool, but ONLY in the higher load/torque areas.

Everything else is best left stock (you can also shift columns down, along with the axis values, if you need room up top)

Here's the latest log. I feel like I'm getting close to the limit with the stock hardware. The IDC is under control now, maxing out at 95%. Fueling is (mostly) doing what it should I think, and timing is optimized in the higher rpm range (literally no more advance possible without corrections).

Setting the last column of IOP to all 99 did the trick, and I also modified IRL to request the load I expect to see from LDRXN at those rpm ranges. After these adjustments I needed to go back and trim LDRXN down to bring the IDC's back under 100%. Requested load is now right along with specified load. Thanks for the help nyet! prince

So basically, I'm looking to fine-tune all the nits and hang this one up. I'll post the actual bin file when it's done. The car feels quite fun to drive now, but somehow I feel like this is just the beginning.....

Thanks D. I'm really happy with the project. Mostly now I just want to make sure it's bullet-proof. Then it's on to bigger and faster things I guess. This train doesn't stop does it?
