ok i have searched and decided i would post this. i understand that hondata remaps ecu's for rsx-s and other hondas. i also know that they do not have this procedure for the civic motor. in my quest of all motor hp, does anyone know who can re-map an ecu? when i mean re-map i mean clear it, and set a new rev limiter, timing of valves, and spark and everything else. i don't know if any thing like this exists for the civic, but i also want to know if there is a way to do it myself. is there like a computer program or something? just wondering. thanx for the help in advance.

To my knowledge there is no one that re-flashes the civic ecu. However there is the AEM EMS which is an aftermarket ecu that is fully programable. I dont think anyone on this board has this, so you would be the guinea pig as far as install & settings.

You could try searching the www.pgmfi.org forums ive read there in the past that some have lookd into flashing our PC's but im fairly certain that its not been completed yt

I have an a EMS and its totally sick. Very expensive though. Other than that you are screwed. I heard of someone trying a k20 ecu with hondata Kpro on our d17s but im not sure if they ever got it working. its almost the same money as an aem by the time you buy everything anyways.

i know if you go to the helm manual website and become a member; you are able to buy honda specialty tools and one of the tools you can buy is a device that can can completly reprogram your stock ecu. that is if you know how to read the language/code, re-write the startup program, fuel map tables, etc. Definately some reverse engineering involved, but besides the EMS this is the only other thing i know of.

Well I dunno about all that but if you are a SICK computer engineer and car tuner you can probably rework an ecu. Other than that its not something you can pick up a how-to book and figure out.

What kidna gains did you get from the EMS?

 
Rep Power: 298

Well none, or all. Because its not designed to be a bolt on and I couldnt get the car to run consistent all the time without it under boost. Its really not a part that you buy as a mod. You buy it to be able to mod your car with no restrictions, therefore its not really a measurable mod. The car runs like a factory boosted car without any problems. How much is that worth? get what im sayin?

the obd-2 ecu's cannot be chipped to be remapped, which is why on older civic's they have obd2 to obd1 ecu harneses to be able to run a chipped ecu. and as for our cars we cannot use this harness becasue of our ignition. it is individual coils and timed by the ecu, unlike older cars which have distrubuters. from my knowledge the only way to change the things you want would be the aem ems, which i not sure if it will actually change your rev limmiter. or somehthing like greddy emanage which will change your ignition timing. hondata did not make anything for our cars seeing as there is no realy demand for the unit, as much as the memebrs on this site seem to disagree with. just because 100 people want it dosen't mean they they wil linvest millions in something to sell 1000 units and lose money. and in order to reset your valve timing you will need to get an adjustable cam gear. seeing as it is a mechanical change not a change in the electronics.

the information above is correct. To answer any questions, you can change the rev limit along with everything else that is controlled by the ecu. I am sure that you could put damn near any engine in our cars with the right ems. It is an extremely powerful tuning tool that can make or break your set-up.

I want an EMS

 
Rep Power: 337

i believe the aem ems is essential for tuning. but for 2k its alot. i think its worth it. the site says it comes with computer software so im guessing that will have a tutorial of how to change stuff around. and yes the individual ignition packs on each of the cylinders are a pain but i think its better for our cars. another question everyone, if i plug the ems in the ecu and program it with my laptop, do i need to keep the ems plugged in my car still or do i take it out after the ecu is reprogrammed? just wondering. cause if you just plug it in and reprogram and take it out then i can convince others to group buy around the ga area. would be much cheaper. and smarter if others are doing it. any ideas? thanx guys.

It plugs in and stays there. It replaces your stock ECU

Is this possible the 7thgen ?

 
Rep Power: 381

nope the codeing on the 7thgens are alot more complicated than with older computers. you can't just write a rom chip and put it in liek you cna on obd-1's.

 
Rep Power: 813

There is a jet-chip service where they reprogram your ecu, but its not very good. I think all they do is put some timing advance and stuff. Better to get a vafcii and dyno tune it.

It's not a written ROM chip. Its a replacement of the quartz chip to that of a higher frequency.
