HP Tuners now supports JTEC PCMs

Bobzilla said

Looks like HP Tuners now offers support for the JTEC PCMs. Now there is one more tuning option available when swapping Magnum engines with the factory fuel injection system from the Dodge trucks, Durangos, and Dakotas.

I am curious to see how it compares to the SCT Advantage software and the Syked ECU tuning.

I'm running the factory JTEK ECM reflashed with a remote tune via an SCT Tuner. It took about 3 programing sessions to dial my 408 Magnum in. It does have a pretty decent cam in it too (246 @ .050 In & 252 @ .050 Ex on 108 LSA)

I had a local shop dyno test the car while measuring the A/F ratios, and it spun out 500 ft lbs of torque & 382 hp at the rear wheels with nearly ideal A/F ratios. It was nice to see the tune was so close.

I used a Hotwire Auto Hot Rod harness to hook it up, so it was very much plug & play taking only 4 wires to be up and running.

Some day in future, I was thinking of lowering my compression, upgrading my reciprocating assembly and adding a single turbo to the car. I'm thinking of using the smaller Holley computer to add more tuning features at that time.
