has someone successfully removed one of these, and how did you go about doing it?? i've started on my removal, re routing all my vacuum hoses and so far the only problem i'm having is of course the vacuum advance...duuummb

search!!search!! search!! there are about a hundred threads and a complete sticky in carb tech!!
i guess i should've mentioned that this is for the EFI motor, not the carb'd motor...i figured posting a thread under the, "EFI Tech" category would give it away, but i suppose not. there are differences i'm assuming with removing the vacuum box in EFIs as opposed to carb'd motors, hince the reason i'm curious about removing the box in an EFI car, for the fact that there are certain sensors that require readings, like from the vacuum advance, et cetera

Just convert to OBD1 and get rid of all that crapola.

and converting to OBD 1 i'm assuming is just a matter of a new ECU and distributor, or a whole new wiring harness for the car??

click on my profile and go to posts of mine or pm me i dont have the lines anymore so i cant rEALLY DO A WRITE UP . BUT I EXPLAINED IT. sorry for caps lock it took me a day or 2... pretty easy and gave me a lil more top and bottom end and accelration. not hard to do. is good mod for extra performance and looks . i took apart black box and only kept the map sensor and the ignition controll module and then re routed the couple of lines that were left. i posted vacume diagrams too to help figure out where everything needs to go
im pretty sure the vacume advance is just re routed to ignition controll module inside black box.then to intake. i remove the module from the box
thanks a bunch! it's nice to finally have someone else who has done this same modification. right now the car runs like crap, so d0h

ok. i looked... i took1 line and hooked it up to the intake and then to a t splitter . then from 1 of the ts lines to the front of the two vac lines on distributor. then from other line in tee to another t. and from one of that t to the piece on the thermostat with vac line. then from the other side of that t. i plugged vac line from there to the ignition controll module that was line 12 to a check valve.. was. and i didnt hook up ac idle boost so i unplugged that and check valve. and plugged the vac line into that on ig cont module. then other line out of ig cont module goes to the rear of the two distributar vac lines. and i hooked another vac line up to the map sensor and that was all. and i re routed any other vac lines that were necesary and not plugged. thats how i did it on my car and it worked for me and i still get 27 ish on the mpg and ... my car was noticibly quicker after vac line removal.
so you just need the ignition control module, and MAP sensor??

thats what i have and my car is workin awesome and fast. i played around and in the end that is all i needed. also i found a lil bit of info on the preludepower. .ccom. not much but it helped someone there said that was all they had and so i checked a bit and lookd at the diagrams i posted above and then i color coded the diagrams and went to the car and started unpluggin stuff to see what affects it would have and re routed till i got it all cleaned up then . re routed again to clean up left over vac lines. and it worked awesome since then. recently i moved my underhood fuse box to where the black box was but im still gonna move it again to under the dash. that was also easy . just made like 34 wires a bit longer aand re routed fuse box wires to where the black box wires came out the fender
mine is also an 87 so should be the same lines as yours. 88 89 have some different stuff on the intake so i dont know. but i got one of those too so i may just take vac lines off that too later and take pics as i do it
yeah, i just ran the MAP sensor into the throttle body, and the vacuum advance into ignition module

yep.once all the vac lines are gone it makes the engine alot easier to figure out. less complicating to look at
So can one of you write up a clearer instructions on how to do this? I have been wanting to do it for the longest time...
in the next couple days ill take pics of where all the lines hook up that i have left and maybe a video. so u can see how it runs. its good. maybe it will help. i wrote it up . is in my posts if u click on my name and go to my info/ my posts.. also i m sorry but not good at explaining stuff if im confusing
Finishing ur thoughts in your sentences would help lol. But yea pics and then the color coded diagrams explaining what is re-routed where would be the best.
We have to do this to my car sam....
