    Does anyone know where I can get a chip for my ECU that will only reset my rev limiter not my air to fuel ratio or timing or anything like that only the rev limiter any help is appreciated? Thanks.

    why would you need that by its self? you wouldnt make any more power than you already have unless your powerband is up there.

    I dont know of any chips that you can buy with a raised rev limiter but if you have ann OBD1 computer then you can do it with uberdata and not worry about any of the other settings.

    Uberdata

    If you have a non-obd computer, there are other programs but I dont know about them.

    willem eprom burner: 45 bucks ebay
    chips and sockets: around 20
    capacitors and resistors: around 5

    **EDIT**
    Sorry, I didnt look at your sig. I dont think there are any obd2 programs

    OBD2 ECUs are far from trivial to chip. You might as well forget chipping it - OBD1 conversion is the way to go. BTW, if you're going to bother to raise the rev limit, you really should change timing and fuel too. Cam's aren't a bolt-on, and they'll really change the way the car needs tuned.

    **GASP** Cams AREN'T a bolt on?????? <_<

    #1 His car is tuned. (safc2)
    #2 We live in CA (obd1 swap is out)
    #3 If you are going to respond to posts then just answer peoples questions without adding in your two cents because obviously YOU DON'T KNOW SHIT
    #4 Please don't try to educate us "newbies" by telling us about things we were doing when YOU were 5. We all know damn well what the fuck cams do.

    go fuck yourself you ignorant little fuck.

    If you honestly think an SAFC2 is "tuned" then you obviously don't know shit about how the SAFC2 works, what will cause a naturally aspirated motor to make more power and what a piggyback system is. How me the timing adjustment on your SAFC2. Show me per cell fuel delivery adjustment. Then tell me your shit is tuned you little maggot.

    If you want the car tuned right, switch to OBD1 or get an EMS. Just because the state you live in has fucked up laws doesn't change a god damn thing about what being "tuned" means.

    And figure out who you're talking to before you toss your ignorant ass comments out there again, BITCH. (hint: I write ECU code)

    I don't mean to sound stupid but what is an EMS? Is that an engine management system? Sorry I am not too smart when it comes to this stuff.

    EMS - AEM EMS, one of the few standalones that will work directly with OBD2. last time I checked, they were not CARB legal however.

    Seeing as you are in Cali and have to smog the car occaisonally, I would recommend the following course of action:
    -Keep your stock ECU for when you have to go to the ref / and / or get inspected.
    -Get one of those nifty OBD1 ECUs that have OBD2 plugs (conversion harness built in) like the ones Hondata sells, among other people.
    -Tune the OBD1 ECU that looks at a first glance like an OBD2 ECU (look, officer Fatpig, there is no conversion harness! It's my stock ECU) How many cops carry an OBD2 diagnostic tool eh?
    -With the OBD1 ECU, you have the choice of Hondata, Uberdata or Crome - all of which can do a much better job tuning your car than the SAFC2 because they allow independent adjustment of fuel and timing.
    -Swap your properly tuned OBD1 ECU for the stock OBD2 ECU when you need to pass inspection.

    Are you him mother or some thing because I think the guy can ask his own questions. Any way he seems like a lot better person then you because he doesnt spaz at the drop of a hat and the safc2 isnt a percise tuning tool BTW I dont think he posted that he has crower 403's so how in the hell would I know.

    Radnewbie -
    Listen you dumb fucking cunt - I don't give a shit if you write ecu code or direct your Mom's porn business, Jon asked a simple question as to whether anyone had a chip to raise his rev limiter. Some people left intelligent coments like use uberdata and such, but you have to assume that he doesn't know shit and tell him to tune his car because he has cams. NO FUCKING SHIT.

    If you must know, Jon plunked down nearly $600 for a hondata and conversion harness and then got fucked over by the shop - they took his money and left town. So he is stuck using the safc2 for the moment. He is well aware of what tuning is and why he needs it. That was NOT his question. If all you newbies would take a moment to read deeper and realize what people are asking instead of trying to prove how knowledable you are, maybe people like me wouldn't fly off the handle.

    crxb16 - You are right. Jon is MUCH nicer than I am... :D I are not his mother either. I happen to be his best friend of 15 years so I'm pretty sure I know what cams he has.

    Too bad you're an asshole, or I'd be down to help your friend out... Good luck though... :angry:

    radnewbie. I like that.

    http://www.pgmfi.org/twiki/bin/view/Library/ChippingOBD2

    Now go find yourself a 66Q589.
    Now build yourself the programmer.
    You might want to check http://sourceforge.net/projects/pgmfi/ for some 66K ASM/DASM tools to help you find the code that controls the revlimiter.
    You might also want to ask me nicely for the Oki NX8/500 core tools. Being such an asshole isn't going to convince me to have them magically land in your lap.

    Spell radnulb backwards, and then check again to see who is the n00b, n00b. I do this shit so that people can tune their cars, not so shitheads like you can mouth off. I could be a greedy ba$tard and charge for my work, but instead I've tried to build a community of people working together to bring you the freedom to tune it yourself - http://www.pgmfi.org

    I personally thought radnewbie was kinda funny myself. :D

    Whatever dude, that's kewl that you help people out and maybe I jumped the gun a little on my first response but I can't stand it when someone askes a pointed question and then ten (pardon the term) "newbies" spout off a bunch of recycled crap they heard from their homey yo. No hard feelings. :wave:

    Integraslut, chipping an OBD2 ECU is far from trivial. The 66Q589 I speak of is the microcontroller responsible for running the car. Good luck finding one. They were only ever really made for Honda by Oki, so finding some on the open market is proving to be nearly impossible. There is a lot of work that remains to be done before chipping an OBD2 ECU and accomplishing something productive is even a possibility.

    So, what you are saying is that he can't solder in an aftermarket chip on an obd2 ecu??????????

    For the price of ther chip burner ($90-150) the price of the Zif socket and chip/s ($10-25) and the price of an OBD2 conversions harness ($80-150) you can burn chips for your car all day long with Uberdata. Your only problem would be finding some one to tune with it, and all you wold have to do if find some one who knows what there doing work with you on there side time, seeing as how shops are probably not going to support a program thats not licensed and all that. Basicly anyone who can read A/F ratio and set Fuel tables/maps.

    The idea is you solder a zif socket into the ECU, then you have the chips that get inserted into the socket, so now you can swap chips without have to resolder and unsolder, aong with the benafit of a standlone EMS IE no piggy back method.

    The hole despute about safc and vafc being a piggy back tuning device go back to the fact its an electronic device explaining to the ECU how It should work itself when really the ECU know how to work itself just its not set internaly to workth that way thus the SAFC. This way if you encounter problems etc. etc. you can trouble shoot with out having to think with a loop in your head or doubts about the engine management programing.

    Thats a ruff explanation so please no flaming i was trying to brake mit down for him a little.

    Ps. I know you likeing the way this thread took a turn slut :D
