Good morning all, We are about to start an engine swap project on a Land Rover Defender 110 where we are going to fit an early Lexus 1UZ (non vvt) with an Eaton 112 supercharger ! Has anybody on here got a 1UZ engine using Link, as we are not sure which ECU would be the most suitable. Cheers in advance Paul.
Hi there I have some throttle map issues i would like looking an by an expert to see if they look correct. My car got mapped around 3 months ago, its a 3uzfe 4.3L Lexus V8 on Link G4+ extreme using factory lexus e-throttle controlled by the Link. I've never been entirely happy with happy the throttle was mapped as for example, if i wanted to go wide open throttle, i never felt like the pedal needed to go past 75% as it already felt like wide open throttle, but i persevered and learned to use it that way. 3 days ago i had my first drift day, and i kept getting throttle faults and my e throttle relay would shut down all together, unfortunately being stranded in the middle of the track i didn't save / memorise the codes, and didn't take a data log either! I took my car back to my tuner yesterday and asked him to have a look through my throttle map as i presumed something was wrong, he made a few changes and made it 100times worse, so i've sort of lost my faith with his throttle mapping capabilities.. So, long story short, i took the car away, got my laptop out, went down a long country lane and played with my PIDS and throttle map tables until i felt like i had the pedal i should have, and so far no faults either which is good The first map i've attached is my tuners throttle map (MGT map, agg throttle) , the second is my own throttle map (MGT map, self tuned throttle target good) Can someone look at the 10% AP and 20%AP range and tell me if what hes done is stupid or am i not reading it correctly.. It progressively opens the actually throttle body as RPM increases, but not as AP position increases... basically meaning the car would accelerate without actually adding any more throttle pedal position?! that seems daft.. so the second map is my own attempt at a throttle target table and the pedal feels how you would expect when driving a car Many thanks for looking, any feedback would be great!

Hi there I've finally got my 3uzfe running in my is200. I used the 1uz vvti basemap and it started first time after i set up my inputs and outputs. I'm very new to tuning / ecus and link software so be gentle! Haha I have a aux 9 and 10 supply error voltage lower than expected for my e throttle. I can see throttle position (11%) but obviously my throttle body isn't working. I understand there is alot of setting up / calibrating to do, but i'd like to get this done before i take the car for mapping. Does anyone have any tips / pointers on how i can set this up? My accelerator pedal works and is calibrated. Is this error due to wiring (which i know is 100% correct and even switched the wires around to test) or is it because a parameter / pid isn't set correctly and is flagging this fault up? Many thanks David
