Hi Guys

Has anyone ever installed a Jet Chip Power Control Module before ?

I've seen one going cheap but I don't know what it is exactly. The part number is 19501S but is this a device to re-program your existing chip or a device that replaces the existing chip ?

The guy I bought my '95 Firebird from said he thought it was remapped already but had no evidence. I've not taken a look under the bonnet (hood) yet to check it out but will do when time and light permit.

Also, with a "Jet Stat" installed to replace the factory unit, would any remapping or adjustments be necessary afterwards or does it simply mean that when coolant reaches 180 degrees the fan kicks in ? Why wouldn't GM make this in the first place if it improves fuel efficiency, increases power etc.

I'd be grateful for any info.

Cheers

I haven't used a Jet chip but I guess GM did it because of emissions.

Because car makers need to make cars that run under just about any regular weather conditions drivers will encounter - plus stay within government-defined values as far as emissions and stuff go ... that also means finding a setup that will work with the whole range of production variations ... running a lower temp thermostat means the engine will run cooler - not only in the summer and under high load, but also in winter - which in turn means it won't warm up as quickly in cold weather, which could hurt the engine (and increase emissions) ...
