Tuning with BRE...questions
 

Hey guys, I've been doing quite a bit of research about BRE here and at pgmfi.org. I'm almost ready to get started on a turbo setup for my car and I've decided to use BRE to tune it. I have a few questions though.

First, as far as chipping a PR3 or PW0 ECU, how is it any different than say a PM6 for turboedit?

Second I am planning on purchasing a chipping kit from xenocron's website, which chip should I go with - the Amtel chip or the SST chip? I would like to be able to use an Ostrich to tune but I may not be able to afford it. Which chip would I be able to use with and without an Ostrich? The website is a little unclear to me as far as which chips you can use with what burner and ostrich goes. Says the Ostrich works with 2732A, 27C128, 27C256, 27C512 but the burn 1 only works with AT29C256, 27SF512, and AM29F040. Does that mean I'd have to get a different burner if I wanted to use Ostrich in the long run?

How hard would it be to tune without the Ostrich?

Sorry for all the questions but these are the ones I couldn't find answers for by searching.

Re: Tuning with BRE...questions
 

The burn1 can only burn chips, and the Ostrich can only emulate, not burn.

So, no matter what you need a burn1 to burn any permanent chips. The Ostrich is just a SUPER convenient thing to have. The Ostrich does not interface or have anything to do with the chips themselves; it just takes the place of a chip in the socket and emulates one.
As far as the diff. between the 27sf and 29c chips, I have used both, and I really liked getting the 27sf because they were much less expensive. For some reason though, I always seem to have the most random problems with the 27sf chips, Im almost a 100% sure its due to me not paying attention to small details, or my fingers being to fat for the keyboard. I never have problems with 29c's. They're my favorites.

tuning without the ostrich using BRE is quite simple. You can use the map trace to put your AFR from a wideband into the corresponding cells, then you can use the log analyzer to tell you where you need to adjust etc. All in all its a good piece of kit

Re: Tuning with BRE...questions
 

Ahh, I understand now. I've never actually seen an Ostrich so I wasn't sure how it worked. :S

After looking at it some more I think I'll save a few bucks and just use a regular chip.

What engine are you going to run it on

Re: Tuning with BRE...questions
 

B16A (OBD-0, duh)

Re: Tuning with BRE...questions
 

Some OBD0 PR3/PW0 refuse to take 29C. I dunno why, they are wierd bits of hardware.

Re: Tuning with BRE...questions
 

I know what car they come out of and what engine they run ---- stick, funny that with me having a Japanese SiR with a PWO-OOO ECU as stock.

You can use them on most OBDO motors and if you was building a high revving D series you might wanna use it on that seeing as it has better resolution all the way up the rev range.

Re: Tuning with BRE...questions
 

What the ---- are you talking about? You asked me what engine I was going to use it on, and then got shitty when I told you. I wasn't telling you what engine a PR3 or PW0 usually runs, ---- stick. I was telling you what engine I'm using it on...which just so happens to be what they're usually used on.

Imagine that. :1

pw0-000 is actually euro spec pwo.

Re: Tuning with BRE...questions
 

Actually, -000 denotes it as a world part, of no specific market of origin. That ECU could have been stuffed into most anything at some point, or be a replacement part purchased from the dealer.

Re: Tuning with BRE...questions
 

you wrote b16a duh, which i took as an insult, if not then my bad, sorry pal

no it isnt EOO and XOO are european market ECU's, the OOO comes from the SiR which is Japanese market only

I dont agree that it denotes that it is of no specific origin, yes it could have been stuffed into anything at any point but, a PWO-OOO is the factory fit ECU for the SiR and the Euro and UK models use the XOO and EOO cant remember what goes in each though

Re: Tuning with BRE...questions
 

-000 is a world part, fact.

Whether or not it came factory in your car is irrelevant. But, most JDM ECUs sport the -Jxx tag.

Re: Tuning with BRE...questions
 

all the CRX SiR's that I have been in, or know of came with a PWO-OOO, I have not heard of a PWO-JOO, I cant even find a J-- on PGMFi, which also states that the OOO is as JDM unit, Im not saying your wrong, all Im saying is that I cant find any information that back up your statement as being true

Re: Tuning with BRE...questions
 

The search engine on the wiki is horribly broken.

Ask any experienced Honduh parts person about the origin tag at the end of a Honduh part number... for example, your ECU in question:

37820-PW0-000

The first five digit number indicates what part it is, ie ECU, axle, cam seal, etc.

The middle three digit alphanumeric code is the chassis code the part comes from... when it is a "universal" part this code is from the earliest origin. This is why you find a lot of PM3 or PM5 misc parts on 88-91 era cars, including the JDM stuffs. Ever notice the SH3 on your tie rod ends?

The last three digit alphanumeric code... first digit denotes market (E, C, J, 0, etc) and the last two revision. Some revised parts are particular to year/model/trim level, others are meant to supercede all (or some) previous parts. In the case of pistons/rings, they often denote oversize as well.

You can credit TJ Schmidt with pointing this out to myself, and a great many others. TJ keeps a low profile, but it was amusing to watch him thoroughly school Brian G of HASport about B-swaps into EW chassis a couple years back. Mista Bone remembers TJ and can vouch for the guy as a walking Gospel.



Now, I'm not saying your car didn't come with an -000 from the OEM, and my cursory look into the subject I'm not finding anything other than PW0-000 mentioned, but I have OBD0 PR3-J01 and -J51 sitting downstairs. A numbering system is only as perfect as the people implementing it, and there might be anything from good reason to no reason why your car got -000.

Sorry if this has turned into an ordeal, I'm not trying to attack you. I see where you honestly misread N1ghtH0nkey's reply, hell I want to smack the guy myself when he's going out of the way to be nice. :P

Re: Tuning with BRE...questions
 

No worries, I didnt take it as a personal attack, if you were a dumbass or a newb I may have gotten annoyed.

You can obviously see how this is somewhat confusing, the PR3 has the J-- to denote that it is for the japanese market. I agree with the numbering system as the other ECU's I have worked with, from a quick glance, seem to follow this rule. However, the chances of all the JDM SiR CRX's I have dealt with, having a replacement OOO ecu in are unrealisticly high, which to me tells me that they were put in from the factory unless there was a product recall and that they were replaced with OOO unit.

I guess this is something we arent going to get to the bottom of though

Re: Tuning with BRE...questions
 

TJ is the freakin man. One of the great minds of the old hybrid forum. Too bad 90 percent of people dont even know the roots. Hybrid memeber since Junior year in HS. Joe_R is still my hero.

Re: Tuning with BRE...questions
 

I was there for a couple months before the Alley. I forget how old I was, but I was still banging HS Juniors. :6

Never really had Joe Rogers strike me one way or the other. But, ---- if Del Emerson isn't the nicest guy ever... I think I still owe him two ECUs :-[

Re: Tuning with BRE...questions
 

Joe_R never did crazy builds but he was the guy to get solid info and how to's in one area. For that if I ever meet the guy gotta buy him a 40. Hell before Hybrid i thought engine swaps were impossible. Man 1997 doesnt seem that long ago.

2007 here we come.

Re: Tuning with BRE...questions
 

i was just getting out of highschool then lol, however i too got to give the hybrid boards credit cause they got me started too....

Re: Tuning with BRE...questions
 

Same nick as back then? I thought you looked familiar.

Re: Tuning with BRE...questions
 

ive always used the same nick but i didnt post much on the hybrid boards...

Re: Tuning with BRE...questions
 

No, I remember you.
