DaveK 0 Posted June 20, 2007 Are there any significant differences between these two systems? Can LE2 parts be used on LU2 etc? Cheers, Dave Share this post Link to post Share on other sites
Rob_the_Sparky 9 Posted June 20, 2007 LU2 is similar to LE2 but uses a Lamda - however, I've never come across a car fitted with LU2 yet and no idea how such a dumb system as LE2 can be made to work with a Lamda sensor! Share this post Link to post Share on other sites
DaveK 0 Posted June 20, 2007 Ah ok, i have the B6E 1.6 engine atm and on the main website its listed as using LU2, was just curious hehe Is that for the cat models then? Share this post Link to post Share on other sites
Rob_the_Sparky 9 Posted June 20, 2007 Most CAT models have Motronic, I've only come across LU2 in books, never in the flesh. Share this post Link to post Share on other sites
Miles 331 1 Cars Posted June 20, 2007 The 1.9 CTi's and Gentry's use the Jetronic system and they run sweat as for some strange reason even with a rock solid idle!! Share this post Link to post Share on other sites
jim21070 2 Posted June 20, 2007 The L-Jetronic system is based around an analogue fuel computer and technically there is no reason why it should not work with a Lambda sensor. After all, it is just another sensor that helps it determine the optimum injection pulse width. It will obviously not be able to do all the clever tricks of a digital Motronic but it'll be able to run a feedback loop to control AFR with a Lambda input. Analogue computers can be remarkably powerful devices and very fast. They fell out of favour because they're more complex and expensive than a digital system and cannot be remapped or quickly diagnosed with a simple code reader. The Lambda controlling AFR very closely will explain why the 1.9 CTIs and Gentries idle so well. Share this post Link to post Share on other sites
