I do not. we've talked about making a bracket to put the heat exchanger water cooler under the rig. I haven't felt the need for one on mine and I'm also know to run deep muddy holes, rocks and brush that could plug it up and damage the cooler.
the Uni-chip piggy back is the best yet of all the guys that have been used for tuning, including one in particular that couldn't figure it out and proceeded to say it's the equipment and not his tuning. we have a base tune that works well with specific plugs, gap, 2.5 bar map and injectors. it's currently being used in 5 rigs. 3 of them are here right now. My LJ will hit the dyno in a couple weeks. there's been no codes aside from a occasional high map voltage on mine when it gets run at 5k.
So, no I.C.? That's great news with regards to tuning. You running the 04-05 neon srt map sensor? Care to show some pictures of how/where it gets mounted?
