ProZac Posted May 26, 2003 Share Posted May 26, 2003 Hey guys, ive been wondering, have any of you tried to add a piggyback ECU or a "better" ecu to your cars? I mean, i wouldn't expect a HUGE performance increase, but a little would be nice :D I'm looking up info on-line right now, but was wondering if some of you would know more? Thanks, ProZac Quote Link to comment Share on other sites More sharing options...
HoeBag Posted May 26, 2003 Share Posted May 26, 2003 jet speed does ecu for the es300...i think you have to ship your current exu to them and they modify it, im not completely sure though Quote Link to comment Share on other sites More sharing options...
steviej Posted May 26, 2003 Share Posted May 26, 2003 jet's ecu is crap, the stock ecu is better. invest your money on something else. steviej Quote Link to comment Share on other sites More sharing options...
SKperformance Posted May 26, 2003 Share Posted May 26, 2003 jet has been known to be shady they say the change eprom settings but under a dyno they give less power or the same ( as if they didn't change anything at all) a complete waste of time don't waste your money unless you want a sticker Quote Link to comment Share on other sites More sharing options...
ProZac Posted May 27, 2003 Author Share Posted May 27, 2003 Well what about one of these http://www.weapon-r.com/ecu.html its got from 95es300's and up. however on the site it gives to purchase the thing, it does not list lex es300. BUT wow... it is still like $700. thats almost halfway to a supercharger. It seems like it promises TOO much also, like a 18~30 gain in HP, is that realistic just from adding a piggyback ECU???

mcelligott Posted May 27, 2003 Share Posted May 27, 2003 JET and weapon R are both junk -- all their products are. The things that the ECU would mod really won't help performnace just because you dont have any other mods to support it. You'd get like a 5 hp increase at the CRANK only if you ran 94+ octane fuel.

ProZac Posted May 27, 2003 Author Share Posted May 27, 2003 I thought so... those jerks!!! :P if i disconnect the battery for like 30 mins. then plug it all back in, would that reset the ECU? or does the '97 not have a smart ecu (like one that learns how i drive)??? i have had the car about 5 months now, and got it from an older lady, she didn't drive it too hard. so im thinking, if it is a smart chip, then i can re-teach it! ~ProZac~ Quote Link to comment Share on other sites More sharing options...
gslx4s Posted May 27, 2003 Share Posted May 27, 2003 Save your money and go for the Supercharger. That alone will make a big gain in power. Bottom Line. Save your money.. Quote Link to comment Share on other sites More sharing options...
SKperformance Posted May 28, 2003 Share Posted May 28, 2003 how can you trust a comany who can't even list an engine compatibility of years it should be 94 and up as they are the same engine never mind weapon r isn't a real tuner just a parts maker Quote Link to comment Share on other sites More sharing options...
