hey guys - I have 2 4.2 ecu's and 2 3.9 ECU's - non limiting! The 4.2' s are out of 95 Classics, 1 3.9 is a 95 D1 and the other a 93 RRC SWB.
The 4.2's are a must if you've done any kind of motor upgrade or simple bolt on power from your 3.9. If you want to keep the 3.9, these 2 replacement 3.9's will simply let you go faster!
4.2 ECU's $145 Shipped each
3.9 ECU's $65 Shipped each
each comes with a copy of "In Search of the Experience" which you can view trailers for at www.insearchoftheexperience.com
happy holidays! - e
