This spring I'm doing my B18c5 swap and I'm getting all my parts together to do the swap. I already have a DC header/ apexi ehaust. And I'm getting my CAI by spring. But I dont have an ecu (because my cars non-vtec and my swap didn't come with it) and I'm looking to get an upgraded one in the process. What do you think that i should get and where should i get it?? Any suggestions P72 obd1???? skunk2 chipped???? p28??? or what do you guys think??? I'm kinda new to the R family so hopfully you guys can help.

get a p73 with a conversion harness or p28 and tune it right

For me,its better the p73

 

Is the P73 only obd2?? or does it come in obd1? Whats a conversion harnesss??? Whats going to be more cost effective?? How much should I plan on spending for a good ECU??

 

P73 is only OBD2

P73 w/ conversion harness would run you about $200-$300

P28 would cost you $100, getting it chipped with Hondata would be $200-$700 depending on which program you want, and tuning it would be $150-$400 depending on how long it would take to tune.

I would go with a P73 w/ conversion harness, at least you know it's programmed correctly.

 

Sorry I hate to sound stupid but What exactly is the conversion harness and what does it do??? Where would I go about getting a good P73 with a conversion harness???

 

if you actually plan on modding the motor any more than just intake/exhaust, i'd just go w/ a p28 chipped, and get it tuned properly

 

Maybe you should Try i Different Forumn...Our cars come with B18C5's...We don't swap them...

yep that is true ...

 

This forumn is getting more and more dumb post everyday...We need to make a test, and you should not be able to post in the ITR forumn until you have passed this test...

 

But to the OP...I'll sell you a P73 for $1,175

The most cost effective way would to run a stock P73 ECU. Get the conversion harness if the years are different between the motor/chassis, or if you're lucky the motor and car is both within the same years.
Then that way it's just the means of finding a P73 ecu to use.

If you were to get a OBD1 P28 you'd need a harness for sure.
Harness = $70
ECU = $120
Then you'd need to chip and hope theres an ITR basemap on their or tune it which will cost another $200+.

Better off gettin' the stock ITR ecu.

 

stock ITR ecu [p73]

 

I got 2 of em that I'm not doing anything with

 

I have a JDM ITR P73 for sale, $130 shipped, never opened/modified

dude, let's do this! We can all give some input on what the questions should be.

But what if I fail the test? AHHHHH!!!!!! Hahahaha.


to the OP, what everyone says is right, as far as making sure you have the right tune out of the gate (p73)

but really, you should spend the money, get a chipped P28, get it tuned PROPERLY for YOUR setup. That is the safest and most power producing route.

Then again, I don't know what you would call the JDM P73. It has OBDII plugs. But it uses OBDI sensors. There is no second oxygen sensor, crankshaft speed fluctuation sensor, fuel tank pressure sensor, etc. And for that matter, there is no purge valve or VTEC pressure switch, either. So it is actually every bit as easy to wire up a JDM P73 as it is, say, a P28. Easier, if you consider the fact that you don't need to send an extra wire for the VTEC pressure switch.
