Yes you can. the plx has 2 outputs, one wideband and one narrowband unlike the others where you have to switch the two. I am however unfamiliar with the wiring of the plx so if you can find out which wire does what, snip the lambda wire near your ecu and connect it to the wire from the plx.
If anything it's worth it just as a safety feature.. If injected before the turbo it speeds up spool times, if you use the correct nozzles and mixture the car will react to mapping as if it's running on 110+ octane race fuel
depends which box your talking about.. the box that is different from the 4efe box is from the 5efhe and is quite a short box. very good for an n/a but on a turbo id say it would be useless until 4th
I depends if they have the same ignition set up. If they do your half way there. you still need to repin part of the ecu side loom and maybe add a wire or two
Are you sure the wire isnt cut/damaged any where? They usually cause a lean mixture when faulty which is then fixed by unplugging the lambda. Are you sure its the lambda? have you tried doing a diagnostics check? Could be plenty or other things as some sensors cause max fuel like the map sensor being unplugged or wire being damaged
If you having trouble just make sure its not losing pressure and moving back into position with the pedal depressed. If it is, change slave. If it isnt, check fork for cracks/damage. If thats good, check bearing and pressure plate
Ive a corolla mani here.. its the 4-2-1 mani thats cast at the 4-2 part and tubular at the 2-1 bit.. if you gonna get a piece of pipe welded in you might as well get this welded on instead ill price it handy for you.
Sounds like a plan! You will need to notch the drivers chassis leg unless you move the whole plant position but then you have to change drive lengths etc
