TR224 -114 initial impressions!
Re: TR224 -114 initial impressions! I still have the stock rev limit at 6200, but I think tonight I'll move it up to 6700. At 6000 rpm it's pullin' like a scalded dog; it want's another 500 rpm I think.
Mine is idling great at 800 with the stock PCM tuning, love that lope! I don't know how it will go over at emissions test time though; too obvious there is an illegal cam in there. May have to bump it up to 950.
Oh and BTW, still no SES lights!!

Re: TR224 -114 initial impressions! Well just bumped up the idle to 950 and the rev limit to 6700 rpm tonight, then went for a long test ride logging the whole thing with EFILive5. I compared this log file with one I made before the cam install, and every thing is still pretty much the same! LTFT's a little negative and O2's 890 mv @ WOT. Idle is a bit smoother but still has the lope, just a faster lope. And it effortlessly revs over 6200 rpm now. Man I love this cam! Only issue is a slight but annoying "cruise control" effect.
Re: TR224 -114 initial impressions! Yes; the RPM's tend to stay high up there when decelerating. You can also leave your foot off the gas driving around and the car will 'cruise' at 2K or so. Also affects the brakes sometimes; I'm still chasing that down and not having much luck.
Congrats Cal, the cam is awesome! I have my 112 at 6800 redline, Harlan shift-light at 6600.

Re: TR224 -114 initial impressions! OK just got the problem fixed . . . I verified the PCM was causing it by unplugging the IAC, and sure enough, worked great. So I plugged it back in and edited the "P/N Airflow Decay" and the "Airflow Decay in Gear" to the max values allowed by LS1edit. Problem fixed! Now I can take my foot off the gas and actually slow down!
Re: TR224 -114 initial impressions! No because it's the rate of airflow decay, or how many grams/second of airflow the PCM is alowing the airflow to be reduced by when you close the throttle.
Re: TR224 -114 initial impressions! I used the "Fill Value" rather than the "Mult %" option. I just picked a large value to fill the whole table with, but LS1edit automaticaly inserted a value that matched the largest already on the table. This was 1.0000 gms/sec for the P/N and 0.0195 gms/sec for "in gear." I would like to have put even larger values, because I can still tell a difference between having the IAC plugged in and not plugged in; there is also a delay before the decay even starts 
. Since it doesn't throw any codes unplugged, I'm thinking about adding my own circuit hardware to disable the damn thing once the engine is warmed up. I guess a simple toggle switch would do the trick also. It is a lot better now that I edited it; before the rpm would just hang at 2000rpm and not come down at all.

Re: TR224 -114 initial impressions! Thanks! It's great to have my car working right again; also just added 5 degrees of timing at 1200rpm and below to help smooth out the idle. Not sure what you mean by braking issues; never had a vacuum problem, but I did have to use my brakes a lot more than normal to get it to slow down. Now I can just take my foot off the gas.
