wiring is different. specs are very very very similar

Google is your answer also GL.

from a tuning and modding standpoint OBDII is the only way to go. the information you can get from OBDII is lightyears ahead of OBDI.

but on the other side it is more complex, so its a tradeoff.

Don't listen to this guy. He doesn't even own a honda.

The motor itself is the same. The sensors and wiring is different though. If you plan on tuning it then obd1 is THE ONLY WAY TO GO.

newtron63h

what does owning a honda have to do with knowing how obdII works? and how does LESS information and control increase tunability?

Dont listen to that **** tart. for tuning OBD1 is the only way to go

JohnnyWash1

You continue to spew bullshit. Just leave the forums already. OBD1 is a tuner's paradise compared to OBD2.

x2 on that. its not even possible to tune a obd2 honda ecu the right way. because hondata, crome uberdata neptune etc. are all obd1 ecu tuning software. hence why every converts to obd1. obd2 imo is a bunch of **** that wanted to help emmisons on cars.

so if i did a obd1 b16 swap into my 96' ek it would be a good idea to get an obd1 eg/ej si/ex engine harness

JKov240

Conversion harnesses are available to go from OBDII to OBDI.

that is unless you live in california, where the emissions laws are just mindslappingly STUPID. Yeah you can do OBD1 and all, but your being able to smog your your car is nonexistent unless you have connections. in your case if you want a b16 get a b16a2, it's the same one from the 2000 SI. but i dunno how rare this engine is. and if i'm wrong it's cuz i'm way new to the honda tuning stuff.

newtron63h

its an unknowledgable tuners paradise because its not as complex. if you know what OBDII is doing then it provides more information. and more information about what an engine is doing is always better.

emissions are only bad if you dont understand how to use it to your advantage. tuning a car using a 5-gas and a dyno is ridiculously simple.

everyone looks at emissions as a power robbing thing when in reality its an amazing way to look at the combustion efficiency of the engine AND a great way to diagnose engine problems.

getting the best performance out of a street car is not about getting around things, its about working with them because a street car has to perform AND be a good daily driver.

is OBDI easier? yes absolutely. is it better from a tunability and potential power view? no way.

since i dont own a honda, im not sure about this, but are the early 90s(OBDI) engines sequential injection?

i just put a sir2 b16a in my ek hatch and i used my single cam d16y7 wiring harness and converted some of the clips to odb1 and wired vtec and got a obd2 to odb1 converson harness and everything works great!

JohnnyWash1

**** off

speedooo

theres one thing i can say for prolly half of honda-tech about obd2 vs obd1. yes the obd2 ecu has alot more you can learn from with the motor and how its performing. but one thing is people that get ecus tuned or actually need there ecu tuned is because of drastic a/f ratio changes over a stock ecu fuel maps. and the whole point of getting your ecu tuned is to have the overall best possible fuel mapping for your vehicle. with a obd2 ecu i've read that the ecu will actually change fuel maps for mods you have one it. so if you get a obd2 ecu tuned (which i never heard of for a honda) and then the ecu will go and change things around with a/f ratio i would think it would cause more problems. why would you want all that because in reality i would think the more simple the system is less likely for somthing to go wrong with it and have problems

Jimster480

your a fkn retard. THere is no OBDII tuning software for honda's (or anything else that i know of). OBDII computers cant be chipped. And OBDII doesnt offer any advantages, it has a secondary knock and a secondary O2 sensor. It was all about emissions and not about making power. If you noticed the boosted japanese cars all left the US when they forced everyone to go to OBDII. MR2 SC, Supra, 300ZX, etc. Because OBDII fails.

newtron63h

so you are saying all aftermarket software tuning on new vehicles stopped in 96?

JDM_kid97

are you really still trying to argue this.....just be done...tito was just asking for advise, not for you to argue about some dumb stuff you dont even know about

speedooo

No, he's saying that you should stop yappin about of nonsense. You're wrong. Get over it.

R666_EK

When will you take the hint? You don't know what the **** you're talking about and you don't own a honda. What are you even doing on this site?

No one said you can't tune obd2. The fact is, obd2 Honda ECU's CANNOT BE CHIPPED AND TUNED. So just drop it.

Jimster480

actually what i was trying to say is in my first like of my last post Your a retard.
