CE LT4 Self-Tune
Most of you recommend to DIY tune. I already have a laptop and I'd to go ahead and try it and I know you guys would support or help me in the process. Which software, where to buy and I'd like to hear your comments.
Do you tune the car in a garage or do you need a "dyno" to spin the tires.
The engine has small modifications:
The bore and stroke are the factory LT4 numbers
Heads were worked by Elliot Portworks. The LE2 package
Valves:
duration - 223 intake 230 exhaust
lift - .565 intake .565 exhaust
Lobe Separation Angle (LSA) 112
The heads flow 285 cfm at .600 lift on intake and 193 cfm at .600 lift on exhaust.
These are the cam's specifications.
Intake is ported
180 Thermostat

The best advice I can give after playing with the tune on my LT1 car is to read, read, read. I posted a link below to a basic guide, but there is much more to be read online about this. I used Tunercat, but there is also LT1 edit. Both seem to be good programs. Just make changes slowly and you will be fine. Hope this helps!!!

I'm the author of those tips (thanks for the appreciation!). If you find yourself over your head at first, I also offer an email power tune for $50. It includes three free retunes based on your own logs and feedback.
I've tuned several setups with similar specs, so I'm sure we could get you dialed in pretty closely.
Have fun tuning, regardless!
