    if this sounds too hard then i wouldnt even bother coope. Even with a harness, perfectly working distributor, and all other parts it still takes an excessive amount of know-how.

    and i doubt you will ever find anybody to build an entire kit to swap this. just too much work is involved, and its not HARD stuff, its just a pain, and unlikely that anybody would like the price on a turnkey setup.

    What do you want to pay for such a kit? I've got nothing but time on my hands to build a kit for someone .. woo hoo ..

    A deposit would need to be paid, for parts, up front.. but I could do it.

    Re: DEFINITIVE GUIDE: OBD1 Conversion

    Actually ... I really don't get on forums much anymore. I'm here because I told Jesse I wanted to make a "definitive" guide for people planning on doing this conversion themselves in the future.

    After running into a couple of problems on his conversion -which should have never been there -hella weren't my fault, i told him that I would document the conversion completely here.

    That my back story. haha .. I'm actually quite proficient with modifying Honda's (Acura :P) ... It's what I do --

    I guess, when it comes down to it, I'm originally from Hondaswap, and then PreludePower, and then, now, here.

    And ... I have no Red X's on the pictures

    Re: DEFINITIVE GUIDE: OBD1 Conversion

    Did you adjust the writeup to cover the wiring that's taken care of with the Civic conversion harness? Or is that still needed to follow your directions? I'm just looking at this now... I need to pull my stuff apart to really understand it! I have a 92 Accord dizzy in my basement, so I'm going to do this conversion.

    Any pics of how you modified the tabs and cam key? I know you said it's application dependent, but it'd still be helpful to get an idea!


    Also, what ECU was used? I'm a 4th gen guy, and we usually use chipped Civic ECUs... P06 for the non-VTEC engines, and P28 for the VTEC engines. What did you use for tuning, and how did you get started (basemap?)

    Sorry if this was all covered... this is all so foreign to me that I don't know where to look for the answers! (weird... just one generation older than what I know, and it might as well be a Citroen!)

    The P75 base map works best. I would either run an unchipped P75 or another ecu(V-tec or non V-tec) that is chipped and running the P75 base map.

    Re: DEFINITIVE GUIDE: OBD1 Conversion

    Cool, thanks! That's the Integra LS ECU, right?

    If I can find a P75 basemap, I'll probably just use a p06. They're quite easy to find.

    Re: DEFINITIVE GUIDE: OBD1 Conversion

    i was wondering if the p06 would work also because i happened to find a great deal on a p06 and a pg7 from a guy on my local forum and i'm wondering since it's non-vtec sohc if it might work better? i know they're easy and cheap to chip i guess just get the p75 fuel map and do that since i can't seem to find one for lx-incredible. i did find an obd1 pr4 i guess it's supposed to be similar to the p75 but i would like some clarification on this too.

    Re: DEFINITIVE GUIDE: OBD1 Conversion

    yeah it will work . if your ultimate goal is to chip n tune then you shouldn't have a problem.

    even a vtec ecu should work. It might not run to nice since it will richen the top end etc.

    I don't know about the PR4 ecu though. Did around pgmfi.org . I think there are ecus that are more preferable than others

    Re: DEFINITIVE GUIDE: OBD1 Conversion

    I ran a PR4(integra v-tec) it ran alright on my car but the tach would jump crazy after like 4-5k rpm. i was getting like 25mpg with a heavy foot... Right now im running a P06 that has been tuned to my car with my 280 cam.

    STAGE 2 - PRIM INT 280 .392 LIFT
    SEC INT 268 .383 LIFT
    EX 288 .394 LIFT
    Recommended for carburetor engine. However, it will work on F.I. with a noticeable idle
    and possibly a slight surge. Strong mid range. No mods are required

    my engine does surge alot when its cold so i have to let it warm up...but other than that its alright now just to finish my swap i need to get a vss signal to the ecu...i have a spare cluster to tinker with.
