HELP-Which ECU
 

:P I know I can get good help here, I have a 91 LS block with b16 pistons and balanced with a 98 intrega head with a complete crower valve train in a 1988 civic HB the ecu in it i beleive is obd0 stock, only revs to 6800 what ecu do i need to be able to rev to at least 8000 I put a friends ecu in, it came from a zc and seem to do better but wasnt set up for what I need I'm tired of ebay flakes saying that the one they want to sell me will work and it doesn't please HELP

Re:HELP-Which ECU
 

What ECU are you using right now? It sounds like a PR4 if you have a 6800RPM rev limit. With is being a PR4, you can chip it and use TurboEDIT to edit all of things you want yourself.

http://www.TurboEDIT.org The software is free. Just download it, edit away.

I beleive it is stock has the light

Re:HELP-Which ECU
 

Chances are it's a PR4.. just chip it (I can do it for you if you want, e-mail me for pricing jparker@driftkids.com) then use TurboEDIT to create your own maps with your own values.

Increase rev limits, tune fuel and ignition tables.. blah blah blah.. If you cna't do that, I can burn the chip for you also and put it in your ECU and ship it back (again, e-mail for pricing).

Right now i cant be without it but i do see you on here all the time and money is a little short as always. damn i like this site i've learned alot thanx for the help i'll be in contact

Re:HELP-Which ECU
 

is the head VTEC or not?

Re:HELP-Which ECU
 

i heard that the cams on the b18a flatten out at 6000 rpms and that in order to get a new ecu hatrack would need new cams and intake manifold to be able to rev higher, and that people cant even chip the pr4

Re:HELP-Which ECU
 

:(turboEF9 Iheard this yesterday from someone else about the cams and intake the same mrpenny is saying at least 1 good thang i have a b16 intake now just to get the cams $$$$ any suggestions than i"ll deal with the ecu

Re:HELP-Which ECU
 

listen mr.2 post... pr4 is very chippable.

take a look at pgmfi.org, ghettodyne.com, turboedit.org
read. learn. share. dont ------ rumors or "i thinks" w/o reading the whole post.

Re:HELP-Which ECU
 

uhm.. sounds like u are running a pm6, stock.. is the civic an Si?? is the integra head vtec or not?

Jason, pr4 is 90-91 LS ecu right? if this motor is an LS w/ b16 pistons he doesnt need to go much higher does he? (non-vtec) ?

i think we should get more details on the car's setup..

if you don't know what ecu you are running uunplug it and look ;)

Re:HELP-Which ECU
 

PR4 comes in two flavors; 90-91 OBD0 and 92-93 OBD1. They are all chippable.

If the crower valve train (and cams, right?) claim 8K revlimit, I'd have no problems chipping for that. You'll have improved the stock LS flat spot in power output between 6-7K, but if the head wasn't at least mildly ported there are good gains yet to be made in that area.

Jason knows what he is doing, and so far has given you excellent advice.

Re:HELP-Which ECU
 

there are actually 3 different PR4 ECUs.
-OBD1 92-93 PR4 (recognizable by OBD1)
-PR4 w/ internal PA sensor (I think these are 91)
-PR4 w/ external PA sensor (I think these are 90)

Only reason I bring this up is that you will have a CONSTANT Code 13 if you put external PA code in a ECU with an internal PA sensor.

I have both internal and external PA PR4s sitting around pre-chipped, I would be more than willing to sell you one on a core-replacement basis so your car isn't down. If interested email me.

Re:HELP-Which ECU
 

hey, i'm kinda new at this what is the diff between in & out pa and code 13 the car runs excel now just that when i had a friends ecu from a zc it seem to produced better and pull harder at 8000 how much with trade. i"m waiting to here from 88crxsi with some ?'s thanx mark

Re:HELP-Which ECU
 

those three guys (Joseph Davis, Blundar, and TurboEF9) are more capable of help you out here.

But as you stated in your PM, you have stock cams. Don't count on gaining much past the stock LS motor's rev limit w/o matching cams to the crower valve train.

Re:HELP-Which ECU
 

PA sensor - http://www.nitroburn.com/pgmfiwiki/i...sureAtmosphere

Code 13: the error code (1 long, 3 short or 13 short) that the ECU generates for a bad PA sensor.

This http://www.nitroburn.com/pgmfiwiki/index.php/PR4 will help you identify whether you have a PR4 w/ internal or external PA sensor. Look at your stock ECU for this. I'd bet money you have one without the PA sensor, as in the first 3 pictures on that page.

Let me know which kind you have. I'd sell you a chipped PR4 that is the appropriate type for $50+shipping and your original PR4 as a core.
