p28 ecu what the f is this 4
 

ok got my new bbka chip 2day and i opened my ecu and im missing the chip thats supposed to go in the 20 pin slot #74HC373 do i need the chip that goes there and if so what is it 4. I think my old ecu guy took it when he removed my all motor chip both spots are allready soketed

You need it, I do not know exactly what it does though ???

Re: p28 ecu what the f is this 4
 

since you dont know what its for and you dont know what the chips is for then you need to send me the ecu and forget it cause you should not even be here

Re: p28 ecu what the f is this 4
 

well since u know so much can u enlightn me on whats that spot is for

Re: p28 ecu what the f is this 4
 

eprom chip it is what has all the fuel and ignition maps and other ---- that runs the car

Re: p28 ecu what the f is this 4
 

An octal latch goes there. It latches half of the address sent from the MCU.

You can get one from Fry's or possibly a local electronics shop.

Or I can send you one for a couple bucks. PM me.



Rope. It's your future.

Re: p28 ecu what the f is this 4
 

the 74hc373 are octal D-type transparent latches

from what I gather this chip basically reads, stores, and sends information of the 28 pin eprom/eeprom. It needs to be there for the 29c256 or whatever eprom/eeprom you are using to work.

Edit: you beat me to it, lol.

I know *cough*moates.net*cough* has them for cheap, sorry xenocron.

I guess xenocron has em too, here's the link

---- lick me fag my bad i didnt see the arrow the first time all i saw was a empty socket for the eprom but you are right mad it for a octal latch

Re: p28 ecu what the f is this 4
 

why the ---- woudl somebody socket that spot then put it in when you can just solder the bitch in there?

Re: p28 ecu what the f is this 4
 

thankz guyz :y

Re: p28 ecu what the f is this 4
 

mayb kuzz i have more than 2 car setups an there4 i have many ecus thats why its there jackass

Re: p28 ecu what the f is this 4
 

hey niglet you need to watch your mouth jeff knows a billion times more then you about this ---- and you call him jackass cause he asked why someone would do a pointless mod to a ecu, i vote ban for a week any one second this :6 , you will get no respect talkin like that to respected members of the bourd that have been here way longer then you ---- im about a yr from being og here as well ass alot of others all im saying is u ask a q then dont talk ---- or call name when we post to help you k no hard feeling 8)

Re: p28 ecu what the f is this 4
 

i agree with these guys if u dont know what that is used for then u shouldnt even have opened your ecu.hum?thats nice they way they used a small dip for that chip in case u need to change it with a new one.

Re: p28 ecu what the f is this 4
 

quit ridin his fkn jock strap. it wasnt that fkn serious :7
whoever jeff is if u got offended my bad dog.

Re: p28 ecu what the f is this 4
 

I do this on every ecu I chip, you know you wont have problems getting the chip to hot when soldering it in. I got a whole pile of those 20 pin sockets for dirt cheap on ebay and it makes me feel better.

SWEET!

Re: p28 ecu what the f is this 4
 

hahaha thanks.

guess it kinda makes sence, just never had a problem with them getting hot before while chipping or had one go bad and have to change it.

people do that all the time. have no clue what they are looking for but just want to open it up to see what was done even though they had no clue what it looked like before it was chipped :1. i think its great when you chip an ecu and get a call saying that it isn't chipped because it doesn't look like anything has been touched :S.
i did one a few weeks ago and didn't put a chip in it yet because the guy is a friend of mine and i was gonna be burning him a map once he put his turbo on and i figured there really wasn't a point to burn a map for a p28 when i could just leave J1 not jumped since it was a p28 ecu and just read the stock rom. he opened it and called asking why there wasn't a chip in it so i had to try and explain a few times.

Re: p28 ecu what the f is this 4
 

let me guess, ross?

I gave him 2 chips yesterday.

Re: p28 ecu what the f is this 4
 

hahaha yeah you guessed it.

Re: p28 ecu what the f is this 4
 

---- back in the day, places would solder the chip in there. I've seen so many ecu's done that way. Mostly from so called tuner shops that have a tamper sticker over the case.

I have never seen an actual "tuned" BIN. All are simply spoon, mugen, J's, etc. All crap.

Re: p28 ecu what the f is this 4
 

YEA THATS WHY ECUS that are chiped from factroy have a chip right in the board.and them spoon,mugen,and jun, bins blow nutts.they make u run rich and most of the time throws code after code.

Re: p28 ecu what the f is this 4
 

Actually most of them don't throw codes.

They disable everything and on top of that, most of them run in the so called Debug Mode.

Re: p28 ecu what the f is this 4
 

true and they have no rev limiter which is dangrous to me.IMO i wouldnt trust them nuttin like a good oldfashion base map and dyno tune. ;D
