Do you need to run an obd2 for emissions cuz id highly recomend a chipped ond1 ecu with jumper harness. The prelude ecu needs to see a chiped key to start.
And vaccum lines are hella easy. Diagrams are everwhere. Again more info would help is help u. If you wana give a one sentance question and get a detailed explanation you ggotta be dreaming
Lol this is why I'm stuck can't really explain myself fully is why I need a tech to look at it thanks for all your input btw, I got the mobilezer removed and those diagrams might as well be in Spanish to me thought it would be simple but I see it's not
I managed to make an auto h23 ecu run but it sucked. Best bet is a obd1 tuned ecu, with a tune of course. Mine runs 190whp and 170 wheel torque , running a t2t4 LSD trans, not the most exciting but I enjoy it!
