Looking for honda-tech members running hondata in their H22a powered accords to share and help out with hondata roms and tuning. There seem to be very few H22a's out there with the hondata setup

most H22a swaps use the 'lude ECU... Hondata is overkill... Hondata is only beneficial when going FI... or series NA...

 

He is serious NA.

 

thanks Scott

 

i believe markaccord95 has hondata 3b, not sure tho

 

i guess i can join this thread, im jspec h22a LSD, now running P72 w/ hondata stage2, tomorrow nite im getting dyno tuned.. yup big $$
but i will finally be getting rid of EGR cel ..(P72 has no EGR) and my idle will be better plus im tuning for best whp with my mods..

se93: i need to know how your setup runs with vtec and low end and such? btw how are your secondaries setup and what is the best thing for a h22a running P72 with hondata..

i will get pics up tomorrow nite of my dyno plot and so on.

 

Hello Chameleon:

What's up? Nice to know there is someone other than myself out there running the hondata system. What kind of mods are you running? You know, i am still have the EGR valve connected. Did you cut a gasket and put it in between the EGR and intake manifold opening where the EGR goes, or did you install the heatshield gasket? I've heard good things about that heatshield gasket. I will be isntalling this as well pretty soon. Of course, if you go with this gasket you will need to bypass the coolant flowing to the t/b and intake manifold.

As far as my setup goes, it's running well. I hope to be getting a lambda meter soon so i can tune air/fuel ratio and then get it to a dyno as well. Not many dyno's here in Puerto Rico. Need to go quite a way to get to one of the two on the island. General performance is very good, and pulls nicely. I still have the secondaries working as normal. I've heard lots of negative things regarding eliminating them from working, so for know i will stay as is. What base rom are you using?

well ..my mods:
Lude AEM CAI 3", DC 4-2-1 Ceramic, Greddy EVO, UR pullies w/ crank, plugs/wires, hondata IM gasket, CM 8lbs FLywheel, ACT street clutch, Quaife LSD, and the engine was taken apart and almost everyhing replaced, from timing belt to water pump, timing belt, head gasket, milled head. prob sum things im forgetting.

i just noticed the other day that my secondaires havent been working for a while since the bottom of the vac hose somehow melted off, i noticed my low end sucked but just thought it was just me. i went to go pull the vac line off to see if it would make a difference on the P72 w/ hondata but then the bottom came off real quick and u can tell it had melted off.. weird. and yes i have the hondata gasket installed, my mechanic didnt drill the port to the EGR thats why i get a cel with my P13 and my idle fluctuates. when you say "you will need to bypass the coolant flowing to the t/b and intake manifold" do you mean i missed something?

hmm i definitely can feel my low end sucks on normal driving on takeoff.. that i rev to 4 just to get going when before it would pull fast on low ...tomm morning im hooking up the secondaries anyhow possible!!!

im using my P13 right now since the P72 was unbearable!! anything from 3k+ would be lag heaven but vtec at 6grand would kick me in my seat.. so until i go dyno tuning tomorrow im using the jspec P13.. on the rom subject all i now is that im running a stock P72 except im on a baseline h22a so its set to use 340cc injectors.. so i wont run lean ..thats all i know.

waiting 4 ur response

 

Yea, get your secondaries working again. The stock P72 rom lags quite a bit where you indicate but after that it feels very, very nice, contrary to what other people have said. So you are running the hondata IM gasket? How does the car feel? Run a hondalogger session and you will see some really nice and low air intake temperatures. To gain the full effect of the gasket, you will need to eliminate the coolant lines that run from the IAC and the thermo valve located on the lower part of the throttle body. You should have received the coolant bypass instructions with your gasket? Do you still have it? I'd like to get a look at it myself, to see exactly how they recommend these lines be eliminated. I bypassed all of them and have not had any problems. Maybe its because i live in the tropics, but it feels good.

hmm the secondaries i will have hooked up again tomorrow morning and take a test drive cuz i will know any difference if any right away.. on the coolant lines.. my mechanic was the one that did the gasket while my engine was taken apart.. so i dunno what he did other than just put the gasket on.. since i know he didnt drill out a hole for the EGR im sure he didnt go as far as doing the coolant lines.. and whats weird is that all my parts basically went on together so its not like i can feel a difference. i will try to investigate about the coolant lines and get some pics.. if its something woth while then i would do it.

 

Sounds good. Let me know how the tuning and everything goes. Just for the heck of it, did you disconnect the EGR valve plug running the P72 ecu?

Just curious because i haven't done it. Wondering if by any crazy chance the check engine light might come on even though the P72 doesn't use an EGR. Hey, you know how cars are! Sometimes some weird crap happens that is mostly unexplainable.

everything reagarding the EGR is hookedup right and i have no vac leaks, but knowing that i have no EGR port on the gasket is what is causing my only cel on the P13.. and making my idle like ****. i did replace the tps and that alone made the car run not so rich and it feels better. i will have pics of the dyno runs and all

 

well ..went dyno tuning today, weather was perfect so i guess that contributed to the great results.. anyways.. I ended up getting 186whp and 150wtq..

but the top end is what got tuned, the low end is still GSR material so it runs like crap at times.. im gonna have to get a full tune!!

i need to know what kind of numbers you put down sep93, like when does your vtec hit and so on? for some reason at exactly 3k the car lags, and if im flooring it it makes this weird cam sound at exactly 3k so not sure if its not getting enuff fuel there or what the problem really is? can u send me like your rom or something and i can just have them plug that in instead of paying another goddam $275
