I've been looking for a Second Gen Intrepid and as usual I'm looking for ways to improve the performance before I even have one. Porting and polishing, cams and headers, you can't get the full potential unless you can tune it. With that in mind I contacted DIY Auto Tune and gave them the specs on the 2.7 and here's what they recommended.
(Trim sensors down as needed.)
MS3Pro-PKG1 $1199 MS3-Pro package with 8' (2.4m) wiring harness and tuning cables GM3bar-map $64 MAP sensor GM3bar_piggy $11.50 Pigtail connector for MAP sensor CLTIATwPiggy $17.75 Coolant / Oil temperature sensor IATwPiggy $22.25 Intake Air Temperature Sensor 38NPT-Bung_A $9 Aluminum bung for IAT sensor (Also available in stainless steel) Subtotal without wideband-- $1323.50
The wideband oxygen sensor system is optional, but a very useful tuning tool. We carry the Innovate line.
And here is a quote for a pretty complete MS3X system with the ECU/Stim assembled:
MS3X357-C_BL $645 Assembled Megasquirt-III V3.57 with MS3X JimStim-C $88 Assembled JimStim diagnostic board StimPower $9.50 Power supply for JimStim
MSHarness8 $67 8' main board wiring harness
MS3X-Hrn8 $72 8' MS3X wiring harness
IATwPiggy $22.25 Intake Air Temperature Sensor 38NPT-Bung_A $9 Aluminum bung for IAT sensor (Also available in stainless steel) MS3TuneCable $6.95 USB communications cable for MS3 Subtotal without wideband-- $919.70"
If you're thinking thats alot of money it is so I requested dealer information thinking I could get anyone on the forum a good deal. No such luck; the agreement call for sticking to their suggested retail price. Understandable it just doesn't help us much. I think the best option would be to work with them to set up a group buy and see if they are willing to put together a package price like they have for the Mitsubishi 3.0 V6:
In addition to this I also have a pretty complete parts list for a supercharger setup if anyone is interested.
