HECK NO!!!!!! You are wrong sir. Even the past "off the shelf" kits have been proven to require ...
tweaking as well. In the past there have been many kits than run overly rich.
I love the homebrew because I CAN control and adjust more. If this were true then why does my homebrew car run faster than off the shelf kits.
I know my boost is set about 1-2 psi higher than off the shelf, but I can adjust it up and down for weather conditions which is awesome.
Also, I can control CF's by adding or pulling timing with Lemmi.
I know that Homebrew can only move the map up or down, but given my car is running great and getting amazing mileage.
I just logged it the other night:
BP 93, 58 degrees, 55% humidity, 950' above sea level, 29.95 barometric pressure and logged it in the same spot on the freeway.
0 degrees timing advancement (20-21 psi)
3.53 seconds with CF's = 2.5 - 6 degrees
+3 degrees of timing advancement (20-21 psi)
3.38 seconds with CF's = 5.5 - 9 degrees
My car does require some monitoring, but only seasonally and because I log it before i race every weekend.
With Homebrew I'd recommend:
A wide band O2 with gauge data logging software
ROSS-TECH Vag Com
APR ECUx (ECU explorer).
Explorer is amazing!!! 1 pull and I can collect an A$$LOAD of data!
I believe the off the shelf kits are much better now. Actually, APR seems to be extremely consistent. Autospeed is probably a serious contender as well.
You have to figure out what type of person you are to decide on the proper set up.

wrong. most of the time *current versions* of off the shelf kits will do just fine.
sure theres more power to be gained by tweaking, but its not for everyone.
if you've been following this guys posts, you'd understand that the homebrew route is NOT for him. hes gonna end up with a big hole in his block and a bigger hole in his wallet.

I'd like to compare some of your homebrew ECUx logs to my APR kit logs. I've been
very impressed with how smooth the APR software runs. Do you have any FATS type logs where you go WOT around 2500 RPM. I'd like to see how it compares with APR down low as well as the upper RPMs. You could email a log file or csv file, I have ECUx as well.

Like I said, the APR seems very consistent lately. If I were going to go off the shelf ...
I'd get APR right now.
I Promise I will log the car soon. Unfortunately it is supposed to Thunderstorm tonight. I'm very interested to see the comparision as well.
Here is my master log setup right now in ECUx:
TIME
Gear
RPM
MassAirFlow
ThrottlePlateAngle
IgnitionTimingAngleOverall
IgnitionRetardCyl1
IgnitionRetardCyl2
IgnitionRetardCyl3
IgnitionRetardCyl4
IgnitionRetardCyl5
IgnitionRetardCyl6
OXSVoltS1B1
OXSVoltS1B2
IntakeAirTemperature
Anything else?
I'll e-mail you my logs with 0 degree and +3 degrees of advancement. I've since dialed it back to 0 in Lemmi.
Do you want me to floor it AT 2500 or before so that it hits 100% by 2500?
