mopar computer

Has anyone tried the mopar computer or the jet chip? Can you get away with 89 octane or do you have to use 93? Does it really work? I have a dual k&n filter from turbo city,a jacob's ignition and flowmaster and they really have not helped power or mileage.

Re: mopar computer

Want more horse, then headers and dual exhaust will help, I hear that those chips help too but as for gas octane requirements, I guess it depends on what stage chip you get 1,2 or 3 or at least I think theres 3 types. Trail and error I'de guess, if it pings then the next octane up... I would have put in a chip but my 95 needs a whole computer and not the cheaper chip instead. Theres also a supercharger if money is not an problem. good luck!

Re: mopar computer

I haven't heard anything good about the jet chips for our Dodges, but everyone I know that has used the mopar pcm has been very impressed. As far as the 89 I am not should be able to run as low as you want as long as you aren't getting detonation....lower temp thermostat would help with that.

Re: mopar computer

If you put in a lower temp thermostat, doesnt' that fool the computer into thinking the engine is not warm yet therefore staying in the "choke" mode and dumping more fuel than required into the engine? Isn't that why putting a lower temp thermostat makes the pinging go away? It also doesn't go into closed loop, does it?
