Well I am nearing the point in my swap where I am going to need to retune and delete certain things in the stock ECU, however I only have the engine harness and not the body harness so there is no OBD port to plug into.

Do the EFI Live and HP tuners both need to plug into the OBD for tuning (I would imagine so how else would it communicate)?

If so I am sure I could get a body harness and make it work if thats the only option...

In my previous motor I was running a Haltech PS 1000 Standalone ECU and I loved it, however that was only because the Toyota ECU is read only and files cannot be altered.

However the Chevy ECU is a read/write which I love except thats its not realtime tuning that I am aware of..

Also I have the stock dash cluster from the 2001 Camaro donor vehicle and also have the plug for it (with about 2 inches of wire), is there a body module that allows this to work or can it be wired directly, I just dont know if there is another computer that sorts things out for the cluster...I would love to mount the Camaro cluster in my dash so the speedo and gauges will work instead of trying to get the Toyota cluster to work.

Thanks for the help guys, just getting really close to fire up, got my Headers built yesterday!! Sooo close I can barely wait!

I went and pulled an OBDII port from a car in the junkyard, and wired it into the corresponding pins on the PCM. the only other way you could do it was to find a car with the same PCM, swap PCM's, flash it, and put the flashed one back in the car with no OBDII port.

You can buy a new ODBII plug with pigtails for around $20 and wire it in. Its only 6 wires that need to be hooked up.

Easy enough problem solved.

also you can tune real time if you get a "Roadrunner PCM" and use EFILive.
