Computer program options for 5.3l swap? These are the options offered by spareecm on ebay. It includes the pcm with the tune for around $150 shipped. Seems like a decent price, speak up if it isn't since im always up for saving money!
- 2001 - 2003 LS1 Operating System Installed
- Eliminate VATS (vehicle anti-theft system)
- Rear O2 Sensors Delete
- Fan 1 Temperature On and Off Changed
- Fan 2 Temperature On and Off Changed
- Axle Ratio Changed
- Tire Size Changed
- Top MPH Raised
- RPM Limit Raised
- A/C Deleted
- EGR Deleted
- Air Pump Deleted
- Fuel Tank Pressure Sensors Delete
- Disable Torque Management (with automatic)
- Disable Skip Shift (with 6-speed manual)
I was going to have all the VATS, O2, A/c, EGR, Airpump, Fuel Tank pres, done.
My first question is if im only going to run one fan, what temp should it come at? My radiator is a PRC Performance Rod & Custom Aluminum Radiator, and its going into a 33 ford so its not the biggest radiator, but is supposedly rated for 400hp. If space alows me to, i might run a fan infront and behind the radiator, what would be a good second temp?
RPM/speed limit: What can a stock 5.3 rpm max at? Speed i will set to 150, but never plan to get that far. I will retune once i modify the motor.
Next What is skip shift???
Lastly, are there any software tweaks that will get a little more hp out of a 5.3 w/ ls1 flash?
Thanks in advance for the help!

Let me know what you end up doing, I am building an 87 p/u with a 5.3 in it and am modifying the harness and tuning the computer myself. I already have HP tuners though...

My '33 Ford has a copper brass Walker radiator and it cools my Ls1 great with only one fan, even with the A/C on. An aluminum radiator should work even better so I wouldn't bother with the second fan. It probably wont fit in front of the radiator anyway, and would most likley block more air than you want. I'm using the low speed cooling fan wire in the harness because that's the fan that comes on first. I can't remember what temp I had it programmed to come on, but I think it's somewhere around 185-190.

I used spareecm, worked like a champ, plugged it in and it fired up. He will set whatever you want, just call him.
Fans depend on what stat you run, and where you want your engine to operate. I have a 160 stat, and fan set to come on at 175.....
Again, RPM based on your setup, cam, crank, rods etc......stock setting is around 6,200 I think, might be wrong.
Yes there are many other "tweaks" you can do to make it run better, timing being just one of them.

Do you have any pics of your car? Are you going to do a build thread?

Looks great! I wish i could afford a real steel body, but for my first rod and second project car i can't complain. Build it till its drivable and enjoy is my plan, then once the winter comes i'll start working on finishing it more.
Im going to do a thread, but i've been more concerned with getting it done! Im still parts hunting, and learning about ls engine's/t56's. And hot rodding/car building in general.
My body is from a kit that i bought third hand. And frame was from a 40's chevy, that had a gm 10bolt and parallel leafs up front. Up to now i've fit a c4 vette irs and ifs, and mounted the motor. Today i got the body back on the frame with the motor mounted and it fits great, except that i need coilovers to lower the front properly, and that my truck pan is a couple inches from the ground.
A build thread is coming, won't be till i maybe get my motor running, but when it does it will have a kicka$$ first post!

So i still havent boughten my ECU, and have a few last questions.
If anyone knows reputable tuners that can do a quick mail tune, including the ecu. I will use spareecm unless i find someone cheaper but still reputable.
Second, how well will the 5.3 run with an ls1 tune? I also might throw my ls6 cam/springs/ pr in now, is it worth it to tune for that?
