Tips for tuning 231/237 cam any tips for an a4 car? so far all ive noticed is the p300 missfire code popped up...so the converter/computer are flipping out when it comes to locking up. Stock tune its driveable but has its little issues...ive also noticed when ive gone wot down low where it would go into 1st or 2nd it doesnt want to pull very hard...not sure if its cuz of the tune or what...when on the highway in 3rd of 4 it feels fine though so im not sure what thats all about...i didnt autotap it last night when i went out unfortunatly so i dont know if im having any KR er what...I'll try and post up as much info I can later on tonight about whats going on and when.
98 Z patriot S2 5.7 heads/231/237 tsp cam, pacesetters, 2.73's, ssf3500 is my basic combo.

you gotta disable the sensitivity (esp at idle) for that cam, most people nuke p0300 code as well. Otherwise you'll be unlocked all the time.
Thats pretty much one of the first things done on a cam tune. misfires are going to happen the lower the rpm, the more
log the misfires on cylinders and watch them fly with a cam
and improper tune.
if you disable p0300 but dont desensitize the misfire system you'll see flashing ses lights usually when idling at a light.

You may drill tb help idle ( I idle @ 650-700 hot and cold - I drilled tb to .210 ) I set misfires @ max=140 and min =120 and no more misfire -no tc lockup problems adjust ve table 400 mutiply by 70, 800 by 80, 1200 by 90, ran atap and adjust ltrms in IFR table to get to -3 or -4 , ran atap and adjust o2' @ .880 - .900 by useing pe/rpm, play with the TC tables to stop jerking when cruseing @36-41 mph with TC locked up,I am runing stock heads with ALL bolt on' over,under and in between, front to back , if you like PM me and I will email you my Edit file so you may look at all my changes ( remeber do not try to reflash my file , but you may compair and hope it may help ) ALSO try

So the question of the day. Drilling the hole is good right? IAC will sweep less.
Dialing in the TB hex nut to crack it open can push it out of the idle cell?
wimped out on 7/32 ".218" but did 3/16" and now all my warm restart issues are gone.
will update on cold start. Guys what are desirable "cold/warm/hot" IAC counts? (Desired/vs/actual).
I'm gonna get hptuners shortly (car is edited already) so i can adjust this and that. Still getting surging at 1000-1400rpm locked up in 3rd or 4th. So any tips on that would be appreciated.
Only took about 10 minutes to do it since i have had the TB coolant bypass The mod finally paid for itself..
.5V 0% tps 4.61V 100% TPS
3/16" hole drilled = no warm restart problems = still surging at low rpm lockup
So yeah drilling helps. I'm guessing there will be less IAC correctio when i lower the idle down, and i'll probably do 7/32 if the hptuners product allows me to idle lower (Currently set to 1000-1100rpm in/out of gear).
Should in gear be so high as well? Makes the car wanna jump off the light with no brakes.
opinions?

GLEN added 8 mph to all the 3rd and 4th gear lock and unlock tables that were under 100 mph now car cruse very smooth - no jerking, because tc is unlockes at this points, can hear moter surging some but do not feel any jerking

i lost several MPG driving around unlocked and imagine the unlocked speed generates lots of heat due to slip heat dissipation. so i gotta tune this right.dammit judd, you shoulda waited to get your shiz, i'd have let you use my y2000 hptuners save a few bucks
Mine will be here tomorrow. I'm in the city, i assume you're out on 400. I got an office up there somewhere. Umm like 3 exits north of the northpoint mall. (not my office, my internet security company). 
I have not bought mine yet, axle just broke and I have to figure something out there first. If we could meet up somewhere, sometime after you get the software, please let me know. I would really like to get rid of the codes for the airpump, cats, and egr., I would also like to get rid of VATS and the airbag light.

alot to learn. most of the example i've seen are not very good.Might want to PM HC02SS. He tuned my car for me (first car he ever tuned) and had my IAC's in the 40-50 range at idle within no time. We had to drill my TB 2-3 sizes larger. Did some kinda relearn process, did a couple of changes in the tables and baaam.....perfect.
