Honda ECU reflashing?
« on: September 09, 2012, 01:48:59 PM »

first off dont even mention the company that comes to mind. i dont care about them, wont sent my shit there.

yes this question is about K-series... but really all 01+ shit in general. i can see it being a benefit to J guys also.

i know that you can get reflash shit for WRX/EVO shit easy. and thats the direction im aiming this post. my buddy had an evo8 with no emissions shit on it. awesome. still would scan and pass emissions. <~that is what im after here. i dont even give a shit about the tuning aspect of it right now. i would just like to toss out evap, o2's, immobilizer, etc to run a motor in a OBD1 car with no CEL in stock mode.

i know of at least one other company that can do it over that other place with a big name. so im sure it can be done.


you can PM me too if needed. but looking for pubic info to bring this to the mass' also.

Are you asking for pubic hair then.  ;DDD

No idea of any companies or R&D tuners that due this, maybe Unichip.  :noel:

been searching for shit for hours, not suprized i made typing errors.


im looking for a non-commercial solution. i have found a couple places that say to send the ECU to them, and they will reflash. but why? i dont really feel like giving that company, or any others really, $300 to flash shit to an ECU.

im gonna talk to some techs at work, see what the Honda shit is capable of doing. i know we can reprogram them. just not sure how far that shit will go. maybe they can rock a "test mode" or something permanently so i can have no emission/immobilizer LOL.

He 100% deserves the business he gets; so yes :)

On pgmfi Darren has been working on the tunable system reverse engineering for some time now, they are very close to having a usable product that's not going to be an ungodly expensive rsx ecu.

password setup is gay over there, locked my ass out... figured it out tho.

now my eyes hurt. i dont understand enough to know whats going on. hate to pay someone to do something really. cuz im a jew.... but there is lots of talk there about actual modifying of ECU code for tuning.

i just wanna run a stock'ish K20A2 (i/h/e) with OEM ECU with no CEL for bogus OBD2 hippie shit and immobilizer. no actual tuning. BUT. would be awesome to get a RSX-S map flashed on a lesser ECU, like a EP3/Accord/something cheap ECU  :Jew:

hell it would be sweet if it was all off like a element ECU and harness. cuz no one uses that shit. cheap ecu, cheap harness, etc. made since? oh yeah, you know im a  :Jew:  im reality this setup is to sell/trade the car. i will just be running a AEM EMS on my turbo motor. just optioning this setup to upgrade chassis lol.

Either doc or dip sells an immo replacement board.

Electrical and physical secondary o2 tricks are widely available too.  Mechanical being non fouler and electrical replacing the sensor with something like a 555 and adjustment pot.

These two things solve your problem, but don't disable monitors.  The obd2 sim project was sold to another guy; who wanted an ungodly amout of $$$ for a unit when I asked him last; should have got one while the developer still had it (I believe it was Darren as well).

They are very hush hush about the actual k development, and rightfully so after hondata's BS they pulled.  They were starting shit like that back in 04+ when obd0 was being developed.... But more like stealing ideas and calling them their own.

I think flashing the rsx rom onto another ecu would be like trying to run a p28 Rom on a prelude ecu.... Not quite the same. Hardware hooked to different mux channels, more/less CPU data lines, different (but similar) core mcu, etc.

fuck, well i emailed him. we will see whats up.


i guess if i run a JDM ECU i dont need to worry about immobilizer as they dont have them, and i think second O2? but that doesnt solve the mupltiplex codes.

stock 02-04 RSX ECU looks to be in the jewish $200-220 range

EP3/RSX base ECU look a little cheaper. but arent for real VTEC motors, and dont have a lockout function (whatever the fuck that is?)

JDM ECUs are little bit more on each price.

found a EDM EP3 Type-R ECU, its cheap, but has immobilizer. but also doesnt require a Honda Air/Fuel sensor, just a standard 4wire O2? kinda like that.


doc has imm-delete for like 120
HR has one for like 200
Ktuned has one for like 160



also. yeah. thats my refusal to run that system, or send my ECU out. AEM has been the plan from the almost the start as my engine management.

Aem is pretty solid; but the interface... Bleh... Barely a step above hondata interface wise.

I know someone that added support to MS1 to run the K in wasted spark/semi sequential mode. He might be OK with publishing it.

And of course, I'll be adding it to FreeEMS in the medium/long term, too.

AEM's interface is better than the hardware, sorry.  You need to dig into a few, you would find them very simple just as you would find their handling of VR pickups offensive.  I've already done the footwork on major component replacement/upgrade and know a number of quick fixes for common problems - nothing you can't figure out, but I figure if I save you some hours now you'll be more inclined to save me some hours later.
