Unichip 2720021 Piggyback ecu for 96-04 4.0 Jeeps obd2 in MD

[gradon]

I'm contemplating selling my Unichip since I haven't been using it. I originally had a split second psc1 that I road tuned and then it got wet and locked up. I bought the Unichip, installed it, verified it worked, then disco'd it until I could get a shop to custom tune it for my stroker(was turned down/ignored by 3 unichip "custom tuners" that would rather work on imports). I sent the psc1 back to split second and they were able to force a write in and unlock it. The Unichip is set up for a freer flowing intake and full exhaust and has ignition advance to take advantage of 91/93 octane gas(my 10:1 4.6 already has to use 93 w/o any ignition advance). There is an a/b switch that'll cut the advance some(but still more than stock) and let you use 87 octane. Anyhow there is a harness that interfaces beautifully with the 3 looms at the pcm, so it is a plug and play--no splicing or cutting or connecting to power. I have the original box. $400 shipped.

Do you have the tuning software and cable?

I do not(apparently you can buy the software for $1000+). Hesco sells the "download cable" for $145: http://www.hesco.us/shop.asp?action=details&inventoryID=52058&catId=7541
I would definitely keep this if I had the software to tune it myself.
