Hey, dont know how old this thread is ( just searched kenne bell) but here is the ltest up date. I emailed them less than a week ago and got htis response when asking them about my 2003 and getting the Optimizer :
Thanks for your inquiry about the Optimizer II. The new computer from Dodge is not going to be easy (they like it that way). To make matters worse, they have created 3 new computers, all with vastly different code. We have already spent a year trying to break the code of the Hemi computer and we're not there yet.
Realistically, it will be about another 6 months before we could even get to other vehicles. We wish it could be sooner, but Dodge will never offer any help to anyone who alters their OEM code.
Sux to be us with 2000+ vehicles wanting the optimizer II. 6 months until they can even start working on the newer comps and then even longer after that to get everthing working good I'd guess. Someday !!
