Jetchip Install Problem --- "engine" light

[aspendog]

I had no issues with the installation but the "engine" light in the dash came on after I started it up. I shut it down, disconnected the neg. on the battery, checked the connections and tried again. Same problem. I took it out and the light is gone...

I am familiar with electrical connections and they were solid.

Anyone else have this happen? Wonder if I got a bad module?

Anytime you mess with disconnecting modules, you run the risk of setting a code. You don't have to disconnect the battery to clear most of them. The car will reset them after 3 good trips if the problem is no longer present. A "good trip" is a start, drive and shut off of the engine.

Thanks for the reply. I understand that a code can be thrown, but this "code" is only thrown with the chip in. As soon as I take it out the engine light is gone, just wanted to know if anyone else had this happen. Has anyone else had the engine light turn on? Did it just take some time for the system to reset itself? I guess I'll be on the phone w/ Jetchip tomorrow.

far from an expert but I will chime in...
it seems you have a non-compatible device so a call is indeed needed. I would ask for a new chip, regardless of what is said.

I am also finding the PCM programming giving 'false' codes when electronic devices are added. My chry. remote start gives off a RKE BATTERY LOW warning and this is a chrysler named product.

So it maybe the PCM and not the chip but since others here have not reported this problem I'm guessing it's the jetchip.

Gluck and as you always do, keep us informed

To say it is a tight fit, as Jet's instructions indicate, is a gross understatement. I actually had to use a small crowbar or prybar to get the ECM back down into its location.

This doesn't sound like it will to good in the long run with either stress and flex of the car or with heat dissipation.

Nah, I don't think either will be an issue. First, the heat fins on the ECU are not blocked at all. Second, the connector that piggybacks on the Jet module is pressed up against a flexible divider that separates the cabin air filter from the ECU.

They claim that it "may" need to be reflashed or replaced. I'll keep everyone updated.

Good move, AP. I have a fair amount of experience with the results of "proggie mods" gone bad. Caution is the watchword. A crated 5.7 Hemi runs about $7K.

I was wondering how long this would take (see my other posts on codes and my Ram).
