silvermate Posted August 26, 2004 Share Posted August 26, 2004 i just ran across this module on ebay think it works??....it says its the same as the jet chip??? i might be the guinea and try it. http://cgi.ebay.com/ebaymotors/ws/eBayISAP...&category=46100 Quote Link to comment Share on other sites More sharing options...
95LS400Bob Posted August 26, 2004 Share Posted August 26, 2004 Yeah I saw it. Be the guinea and try it. :P I do know on a Ford Powerstroke a chip is really amazing. Quote Link to comment Share on other sites More sharing options...
92Lex Posted August 26, 2004 Share Posted August 26, 2004 According to the ebay description it says that the module is hooked up to the Intake Air Temperature (IAT) sensor, in theory it should work because its probally tricking your IAT to send off a signal saying the engine is colder than it actually is..that in turn makes your car run richer. Richer running car at higher temperature = more power. I wouldnt buy it though....if he/she is saying these units go for 200-300 dollars why wouldnt he/she sell it for a bigger profit versus selling it for 20 dollars? Plus look at his ebay feedback score...its a zero. Quote Link to comment Share on other sites More sharing options...
SRK Posted August 26, 2004 Share Posted August 26, 2004 Here is what will happen. Tricking the IAT sensor is an old idea - on the early Bosch D-jet some folks put potentiometer in the circuit and "dialed" up the mixture. On the Lexus, and any car with an O2 sensor, you will fool the computer into thinking the engine is cold and then it adds more fuel. Until a few seconds later when the O2 sensor detects a rich condition, which it then trims out within a nanosecond or two, and the fuel ratio returns to stoichiometric. Big deal. Maybe two seconds of rich running, then it is trimmed out automatically. That device is yet another strange invention dreamed up by some jerk sitting in his basement, who has neither the inclination nor the intellect to understand what he is doing. Don't even think of buying one. Quote Link to comment Share on other sites More sharing options...
TMaxxTim Posted August 27, 2004 Share Posted August 27, 2004 The are a complete scam, all it is, is a resistor put between 2 wires!! The only chips that work are ones that go into the ECU and fool with timing/transmission shift points (pressure too)/rev limiter. I know the Ford Escape has one that affects those, but its not a resistor, its an actual chip. I've never seen one for the LS 400, but I've never looked real hard either.

99lsguy Posted August 27, 2004 Share Posted August 27, 2004 Silver, Just go for an 04 LS 430........you'll get the extra power then!! Quote Link to comment Share on other sites More sharing options...
fatman Posted August 27, 2004 Share Posted August 27, 2004 IT IS A SCAM! You can buy the same resistor in a pack of 5 at radio shack for 1.00 :chairshot: Quote Link to comment Share on other sites More sharing options...
