Alright, i've been on the pgm-fi-crx site and it seeme like there is something available for obd1 car now. Can someone please, clarify the situation for me... is it only dataloggin or can I burn rom and use some sorta Hondata ghetto with obd1 ?

Thanks

There are a couple of free ROM editors in the works for OBD1, but nothing just yet. If you want to make custom programs immediately you'll have to use Excel ------sheets and a hex editor like the rest of us. It looks like a couple weeks is all that's needed to have some pretty good free OBD1 program editors out.

The stock ROMs with datalogging enabled are already available if you want to go ahead and get comfortable with burning chips and datalogging.

Joseph... what kind of USB adaptor do I need in order to connect it to my cn2 port?

Thanks

how do you tune it? do u get live feed back from the engine? usually i tune stuff on a dyno for my rx-7 and check the wide band o2 sensor, to see if im lean or rich, but with ghetto dyne it seems like i can't do real time, just think what i need and then burn it into a chip and see if it works. if anyone got more info i would like to know too.

I got a question about this ghettodyne stuff too, where do you guys get these rom burners and blank roms? Also how much are you guys paying for these things? I've found some rom burners but they're going for something like 300. I'm basically looking for the cheapest way to go.

Also I came across another free gig similar to ghettodyne, but I don't remember what it was. Could you guys post the free programs for this that you know of?

Thanks.

In my 90 crx si (PM6) I put in a ZIF socket can get from here: www.digikey.com part # A347-ND

Burner (what hondata uses)

Once ghettodyne is finished you will be set.
I've currently got a georgehackpm6.bin file that is suppose to allow me to run 450cc injectors and basically be my fuel management for my REX. It's for only in the mean time until ghettodyne is complete and ready. For ignition I was using a MSD BTM to retard my timing.... it was just temp purposes so I could at least run my car... works great.

but..... I don't have my burner yet, so I can't burn that binary file so I have no fuel management yet.

USB to serial, and then you have to make/buy a MAX233 adapter cable to convert from TTL (at the CN2 port) to serial (where you plug into your USB adapter. Nick should have all this stuff covered on his site, www.ecucontrol.com

I use a wideband and AFC on the fly, because I have that crap laying around. I go back and infer changes in fuel maps based on AFC settings and what I remember WBO2 readings to be at certain rpms.

Check the ECU Control site above - it's free datalogging software for Honda ECUs and you should be able to use it's recordings to figure out what/where needs adjustment, even if it doesn't support WB)2 datalogging.

Yeah, what Hondata uses. I've got a Hondata 4b sitting on my floor right now, lent to me by Trickturn (owner of carolinahondas.com) for "oh, six months or so, I don't really care" in exchange for fixing the three broken Xtronics Pocket Pussies he kept buying to use it. He plans to eBay rape someone for all of it when he's undisgusted enough to pick it back up.

For much less than the price of a Pocket ----- you can get the Batronix Eprommer 3.x kit which is very easy to use, and does not break. 75% of the PGMFI Forum people use them.

Your going to lose a lot of power with that BTM, because the "Georgehack" is based on my PM6 1.0 retard MAPhack .bin, which as the name implies is 1.0 degrees per psi ignition retard. The fuel maps are also stock, so I expect them to be a hair lean under boost. If you already have a chip burner you should be able to use Ghettodyne 1.0x to edit them (although the pressure columns are no longer correct) or if the map locations are fiddled due to George's modifications you can use a hex editor and Excel worksheets like the OBD1 guys do.

the 91PM6GeorgeHack.BIN file will work with 450cc injectors correct? I didn't know there was retard code in that file.. I thought it was fuel only.
