Any one do BRE or equivalent obd0 PR3 chipping???

[bmgjet]

Hey there, If im unable to find a gizzmo launch control thingy would any one know of some one I can send my ecu to that will chip it to have launch control, shift light and removed speed cut.


I know this can be done with BRE but I dont have a rom burner.

Thanks

check nzcrx forums or pm "tjones"on here. Hes the guy that owns "THECRX" b20 Turbo CRX. From memory he chips OBD0

i think "Py7h0n" used to chip them and tune, but dunno about now

[mr_tec]

thort it was shifty jono?

[bmgjet]

thanks.

What motor and ECU do you have. I can do it for you if the others fall through.

won't take a second if you just want the things you mentioned above

[bmgjet]

pr3 obd0 j00 out of a 89 da6. Iv found some one that will burn me one but if it falls through ill contact you. Thanks for the offer.

[bmgjet]

Could some one confirm this is the chip you desolder and replace.

on the same topic (sorry to hijack your thread) itd also be good to remove speed cut before NIMM, does someone know if that can be done with a chip on an OBD2A H22a ecu?

saves forking out for a speed cut defender

/noob question

cheers

[d16a7]

dude damien.. your an idiot.. SEARCH!!! even im not going to explain this one for you

and as the OP your chipping Q i dont know

[bmgjet]

Nope obd2 cant be chipped. Unless you want to to downgrade to obd1. Theres another way to remove the speed cut, Cant remember how its exactly done.

Pritty much you just hack the speed sensor to read that its doing 100ks none stop so that it vtec still works + it never speed cuts. Just if you have a eletronic dash you will always read that speed lol.

do convert to obd1 you will need
convertion harness Obd2a To Obd1 Wiring Harness Adapters 4 Sale
and a obd1 ecu (which you will be able to get chipped with Crome.

Might be forgetting something.

Yes that is the chip to desolder.

[bmgjet]

Your awsome ef_eg.

also if you want to do datalogging at a datalogging header to the ecu
check pgmfi.org for more questions/answers

I could do with one of those chips man

[bmgjet]

Im looking up the data logging function and its pritty simple, You just have to have a TTL converter then solder the wires on to the ecu datalog port and cut jp11.

pgmfi seems to be having trouble with there server its up for 5mins then it goes down for another hour.

Im trying to find some where to source the TTL converter with out having to buy overseas so if any one know post away.

[bmgjet]

aparently you can use the nokia
dku-5 cable

[bmgjet]

also found out you can burn chips with a old network card if you have one.

Needs to be a old reltek one that has a port for a chip. I just happen to have a whole box of them so ill try it out tomorrow if i get time to go and buy some chips from jcar.

Just need to do a bit more research.

[beowolf455]

Legend! I used to have a nokia cable, threw it out damnit

[bmgjet]

Damb all the cards I have dont have the write interface on them (RTL8139D). They are still capable of reading Honda chips tho but whats the point in that lol.

Guess im still going to have to buy a burn1.

But for people with old RTL8029 you can use them with RTFLASH to write honda chips.

And or if you have a really old mobo with a 28 or 32pin bios you can use UNIFLASH.

[Coupe-R]

I doubt the Nokia cable will be anywhere near as fast as a decent datalogger, like the one from moates.net
If you aren't tuning then speed doesn't matter

You just have to have a TTL converter then solder the wires on to the ecu datalog port and cut jp11.

Thats for OBD1 not OBD0

Datalogger is a TTL to USB converter, loudsoundz made one using a dicksmith serial to USB converter. However it was the older style converter they sold with a slower chipset (made the cell box miss cells when accelerating)
you want at least a 150-200ms sample time otherwise you are just going to miss out on data when tuning (especially with a fast car that will accelerate faster than you can log)

[bmgjet]

Just finished adding a data logging port to my spare ecu. Wont be using it tho intill I get a in car computer (EEEPC) lol.






You said you didnt need to cut jp11, Do u have to cut anything for obd0???

[Coupe-R]

nope only OBD1 i believe

[bmgjet]

Got it all installed and running today, Almost any one would be able to do it them self.

Only had to buy a 30W soldering iron ($9.99)
solder 200g reel ($5)

Then used fingernail clippers to cut the legs off the old chip.
Then used solder iron on the bottom of the board to heat up while i keep the fingernail clippers on on of the chopped legs and pulled it through.

When I had done that for all the legs I used the fuse puller out of my car to pull the chip off. I should of read up more on this because the chip had glue or something under it which pulled a bit of paint off the board where the numbers are.

Then I just got a really really small drill bit and drilled out some holes in the solder for the legs of of the socket. Put the socket in trimmed down the legs and soldered them in place.

Then went over it with a magnifying glass to check all the soldering work.

Then slotted in the chip to the socket and done.

Adding the data logging port was ever easier and you can do logging with stock chip but only really basic stuff(not useful for tuneing)

Just rip off a analog audio port off a old scrap mobo or back of cd drive.

Then pull the pins out of the it, You will only need 3 of the pins.

Now on the back of the ecu find where the data logging port is and heat up the solder and slide a pin though the hole. Do this for pin 1(ground) 2(TX) 4(RX).

Dont need pin 3(positive) and pin5 is blank.

then side the plastic thing you took of the mobo or cd drive over the pins should go on really easy.
Now take the soldering iron and put the tip down between pin 2 and 4 and it will melt it slightly to it doesn't slide off the pins.

Then you just need to use the cable for that analog audio and wire it up to a DKU-5 nokia usb cable (still waiting for mine from trademe cost $5).
