What a difference....

I have found most of the IX's dont like a large amount of timing up top like VIII's or even older DSM's will. The cammed ones like even less it seems above 6K than stock cams. The funny thing about that is they will take a little more near peak torque but trade it at high rpm. I always thought it would accept more at both but I cant deny the logs I am getting.

Hey nj, if you are tuning in 3rd gear, you might want to do at least one run in 4th gear once in a while if you can find a place. You may find that you are getting more knock in 4th gear where the cylinder temps can build up more.

That's kinda what I had observed from all the posts too. And my IX doesn't seem to like more than about 11 deg at 7k rpm.

Fred has a real point. I road tune using consecutive pulls ~3 in 3rd gear and finish with a 2k-6K pull in 4th ( 6 spd MR ) This give the car a chance to get to stable temps and get as hot as it is going to get. I usually do the runs one way on the section of road I use then duplicate the reverse route.
I too tune for not more than 2 counts, if I see three I take 1 degree out at that range/cell. Car seems very happy.
Quick question is the lean spool only on the IX or does it show up in the modified VIII rom . And it appears you guys then move the lean spool disable to 7500?
Naj: could you do a screen capture of just those tables and pm me ?
Thanks OH BTW glad to see you got your pills. Those folks are gonna be happy!

I wonder if the anyone can explain this to me. Yesterday I logged with the stock mivec map. Today I logged with the JDM RS mivec map. I barely made any changes to the AFR map.
Yet the logs today show a 0.25 point leaner AFR than yesterday. Is that due to the aggressive mivec map of the JDM RS? Why would this happen?
Here is the chart the top one is before and the one below it is the after (mivec).

I reconfirmed my findings today about aggressive mivec making the AFR slightly leaner. I did three logs with the JDM RS map and got the same leaner results that I got before.
If you do not want to retune your AFR multiple times, it is adviseable to start the tuning sequence with the JDM RS map first.
Kudos to TTP for suggesting that in a different thread.

I just want to share my latest data on test pipes. I always wanted to confirm for myself how much power can be gained from a test pipe. So I installed one did a few logs to tune the AFR due to an exhaust leak and today I logged the car. My car gained 13 hp and 6 lbft of torque from the test pipe. These findings are in line with the ~ 10 hp gain reported by others.
Here is the dyno chart of my best run with the HFC and the best run with a TP:
The car is now putting down 34 hp and 17 lbft of torque more than stock simply using a TBE w/tp, leaner AFR, lower timing @ the top end and more timing at the low end and an ggressive mivec map that I found in the mivec thread. I have not even touched the boost yet and I am thinking just to leave it alone even though I produced the pills to do just that
Stock vs. most recent tune with TP

More than likely I will drive the car w/o messing with the boost. I ordered an ebay filter that was recommended by Bryan. I want to test it and see the results. My aim is to maximize the power out of the car w/o changing the boost. I want to see how far I can take the car with simple, good quality and relatively cheap mods.

Here is the stock log, when the car was totally stock. It is a better comaprison than the before after of the chart you quoted. No TBE, no tune, no nothing. It should be a good before and after comparo between DLL and your hp/tq calculator. If you want others, I will post them too.
