im currently testing on my P75 with uberdata. still need to do some major tuning but all is well so far......

 

I'm going to be playin with this hopefully sometime soon but before I do I need to know if using a USDM P28 ecu is not going to cause me any problems in a EDM 98' ITR?

 

No it won't. I'm using an auto P28 running a B16A on Uberdata.

 

I'm wondering if there are any differences in the P73 USDM and EDM ecus. Just wanted to make sure before I splash out on the P28 and conversion harness as it adds up to quite a bit and I don't wanna make a costly mistake.

 

there are some differences between EDM JDM and USDM. If You Have a European Car with Europen ECU Use that one. and disable Knock Eld and PA in Uberdata before you burn a bin and it will work verry nice. Im Eurpean so if you can PM me if you would like...

That way you dont have to buy a USDM ECU... if you allready have one and dont want to use your stock ECU then give it a try...

jdm p72 doesn't need a 74hc373 because it already has one. they run off external memory already so all you have to do is remove the stock chip and put your socket in its place, no jumpers or caps required since it is already running off a rom.</TD></TR></TABLE>

I have a jdm p72 and im just wondering if you have done this before. and could you tell me where the stock chip is? i cant find it. is a a 28 pin chip? this is pic of my ecu. Thanks

 

that ecu is not chipped

 

Yea i haven't chipped it but ndogg said that jdm p72 doesnt need 74hc373, is that true becuase i see a place for it. and i dont understand what this means "all you have to do is remove the stock chip and put your socket in its place". Maybe ill just stick with chipping a usdm p28. sounds easier

well, i have only chipped one ecu and it was my jdm p72 and it had the **** in there already, maybee mine was just special, or maybee thats a p28? on that pic, you need to put the rom and the 74hc373 in there, wich will be a BITCH because it is surface mount on that ecu.

it will work with boost, not the boost controller. my bad.

 

w/ the FTL/FTS is it possible to make it work with the Hazard light instead of the AC?

I'm gonna take a guess and say no since the hazzard switch is in no way connected with the ECU

 

bastards..i figured it wouldnt have anything to do w/ it....Just cant use FTL/FTS since i have A/C...o well

Hey my ecu is identical to that and I just bought it.......so could someone give us a little guidance as to what else is required to be soldered in besides the 74hc372 and the 27256 chip? Don't see any J1,C51,C52 nor R54. Don't tell me I have the wrong ecu please.

 

b18c_00hatch - If you look on the underside of your ecu you will see R54, C51and C52 in place. So you won't need to solder those. All you will need to solder in place is J1 which is also on the underside of the ecu - and of course the 74hc373 and the 27256 chip you would have noticed.

I just decided to check the underside and noticed this. Sorry to bug you guys with the question but I didn't see it noted anywhere in the Uberdata threads and I've been following them all.....and if it was

 

Thanks for clearing that up for me. I got it now. another question though, can I modify the JDM P72.bin (Int269stock) in the newer uberdata without any problems? thanks for the help.

 

am I blind or is that a surface mount 74hc373 blank spot chillin on that? have fun with that!!!!

 

ya thats a surface mount. goodluck.

bigwig- you can use the fts/ftl with ac, there is a box to enable the use of ac. if you want to retain your regular ac capabilities, leave the box unchecked. this will leave you in ftl mode all the time.

also, you can change the code a little and use power steering input or another input that is not used.

FalconGSR and SlashDevSlashNull have done the same..

so in 1.2 it will work you try it for yourself if it wil work on 1.6 but why not use the stockGSR.bin uberdata supplied ?? we used it because it was a JDM bin that could be Raw Hax edited to be used on a EDM ECU

 

I just plugged in my stock JDM P72 in my prelude to see if it would start and run the car as a first test before chipping. I heard a fairly loud "picks" as though a fuse was blown. Shucks! I immediately reinstalled the JDM P13 connect battery lead and it fired up and runs as usual. Now, my car was an automatic and when I did the conversion I didn't touch the ecu or harness. Second, I have an Apex Vafc installed which I didn't remove when connecting the JDM P72. What could the problem be? Did I forget to connect\disconnect something? I'm thinking the battery lead wasn't on secure cuz I just pushed it on and the noise I heard was probably the starting motor solenoid trying to engauge. Hmmm. Any help appreciated. Thanks.

 

It wouldn't even crank, or it clicked when you tried to crank it?

The ECU is not connected to the starter circuit. It primes the pump via the main relay for ~2 seconds before starting and waits to be turned over. When it senses the engine's being turned over it tries to dump fuel + air + spark to 'catch' the engine and get it started. You should be able to crank the car from here to kingdom come without even having an ECU in the same garage as your car. So if it wouldn't crank with the new p13 you can bet it's more likely a mechanical/electrical problem (you say you did an auto-manual conversion?) than a bad ECU.

 

Prelude pinouts are slightly different than civic OBD1 pinouts, you have to swap the wires for either the ignitor or the fuel pump, search, or I'm sure gimpy is probably familiar.

No hazard lights won't work, but someone smart could figure out how to use the the Timing Service Connector.

JDM, 74hc373 Yoh!

Can anyone confirm this? Not that I don't trust you Phiz but I always heard it was plug and play. Even a rep. at Hondata told me that.

Phiz is wrong (no offense). I have 5 P28's running in various Preludes (even one P72 in a 1998). The only Honda that has differing pinouts is the 1994-1995 Honda Accord, A6 and A11 are swapped... who knows why they did that.

 

Yeah, listen to whatever gimpy says, he knows more about the accord/prelude platform than myself.
