Hey there

I am searching troughout the net on every forum i can find about 6th gen h22 swaps..

My concern is about staying OBD2 complyant, for emissions and DTC codes retrieval to function correctly.. In other words, a 100% working swap..
I wish i could find a complete 01+ h22a (the euro one..) with ecu and key and all.. but if i cannot find the whole deal, how do i manage with the immobilizer in the ecu..?

Basically you need a key, a transmitter (for the chip in the key, wich is located near the ign switch) and the corresponding ecu (wich needs the paired key signal to allow ignition). Well what if i dont have thaT? is there a way to hack the computer and tweak with this function?
If thieves are able to steal our 6th gens (without platforms trailers..) well there must be a friggin way to bypass this? right?
lol yes i know it may not be politically correct to discuss those details in public, i need to know.

Yes, i can use a 96 lude (p13?) ecu that doesnt have a built in immobilizer, but beside the fact that it must be pretty rare ----) $$$ Would it allow correct funtion of a newer 2001 engine, emission and power wise?


Thank you

 

a 96 p13 will control an 01 prelude motor properly, but like you said, $$$$$

you might be able to try to source a jdm obd2 ecu, as i thnk they dont have imoblizers, but i am not sure

and keep in mind, your accord 98-02, will have obd2b connectors, the 96 p13, and 97-01 ecus, are all obd2a.

these two are not plug and play, you will need to convert your car to accept a obd2a ecu

they will plug in fine, BUT, it WILL fry your ecu if you try to run it. they share the same style plugs, but the pins #s are completely different

 

Buy an obd2 - obd1 conversion harness run obd1 ecu is also an option.
u lived in canada i guess u dont have to worry about smog.

 

i thikn he's worried about keeping the obd2 scan port function, which won't work if he goes obd1

 

we in canada do not have emissions test yet, but every once in then we get this huge smog cloud over montreal city.

i drive 50 to 75k km a year, so you may, or may not, understand the fact that i am trying to do my share of pollution reduction


everytime i hear someone talking about gutting their cat. on recent cars, it makes me want to kick them in the nuts, and then make them breathe a nice puff of unprocessed exhaust gases..

To get back on tracks, Since i have a 2001, i am OBD2-B , and a 96 p13 would be OBD2-A.. I would simply have to re-wire the terminals going from the harness to the ECU, since they wouldnt have the same pins positions... right?
Hmm then i guess ill have to shop around for a 96 lude factory manual, aswell as newer ludes one..
Or find myself a complete swap with ecu/key included lol

Thanks for the info

 

ah if your only worried about emissions, you can probably get away with going to a straight OBD1 setup. a properly done swap will pass emissions test with flying colors. i am talkin about the actual amount of pollution that your car emits. i've smogged my h22 swap in my accord and it passed the NYS sniffer test which is pretty tough compared to most states.

yes you have the right idea with the pin swapping, but the only thing is, on the obd2 plugs, there are big pins and small pins. so not all the pins are swappable. some small pins will end up needing to go into a big pin area when repinning from obd2a to obd2b and vise versa. your best bet would be to find a jumper harness if you are set on going the obd2 route.

though if your only concern is controlling the pollution, i urge you to look into converting over to obd1, as this will probably be the cheapeset and simplest route to take.

good luck in which ever path you choose

 

thank you very much all of you for these informations

 

Wouldn't a stand alone setup over look the immobilizer?

Just curious.

I got the OBDI swap...and as you said no immobilizer problems. However, from whay I understand the honda dealership can re-program the ECU.

Don't know this first hand.

yes a honda dealer can reprogram the ecu to accept the new key, but i have no clue how much they charge or what's required.


and yes any stand alone would bypass the immoblizer problem

Yeah I thought so...thanks!

I heard it cost about $200 to get it reprogrammed, but this was 3-4 years ago when I did the H22 swap to my 6th gen. The prices may have changed.

 

any updates on the immobilizer situation ? i have a type r obd2 ecu i wanna use
