I'm looking to buy some 27c256 chips. If anybody is upgrading to the 29c256 chips then tell me and i'll paypal a lil cash for your 27's. Thanks

Interesting question, I've never seen such a beast. If you can provide a scan of the top of the motherboard with all the serial numbers and such, I should be able to tell you. If it is like the other JDM ECUs of that year, you have to buy a SMT 74HC373xx... the exact PN is on PGMFI somewhere.

 

cool. i'll take a look. i thought that i remembered someone (maybe falcongsr?) saying that they'd done it (or something like it) before.

 

somebody on the uberdata forum is running a jdm p72.. he said it was easier to chip than usdm ecu.

i don't know though

 

i just wanna confirm, the chip below will work, correct? thanks.

27C256 32K Eprom CMOS 12.5V

 

27Cxxx(N) and 29Cxxx(N) work perfectly.

The "N" means normal or some such... if you have a through-hole pin to solder, aka 28 DIP, aka 28 pin Dual Inline Package, it is the correct chip. If it doesn't have a suffix it is implied, then it's the same thing as the "N"

Just to overexplain the subject, and make a short story real long.

 

Ive been looking over uberdata for awhile now and its awesome Just had a few quesitons.

With uberdata are you able to keep the ecu in open loop? Is this o2 Heater disable under misc?

What is up with Map Scalar? And why would anyone ever rewrite this?

And the p28 bins are kinda confusing. Whats up with the eratic rpm?


thanks and excuse me if these quesiton have already been aswered

 

you must first open the stockgsr.bin file, after you do that you go to import and select import p28 and then find the p28 file you want to use and import it. The reason for this is that uberdata was based on p72 code.....thats why your map looks really funky.

There isn't an open loop option. Heater disable is included under misc. You would change your map scalar if you wanted more "definition" in your boost coloums. I personally am not going to change it, but you could fine tune better if you changed a vacum colum to a boost column.

thanks

 

newb question about datalogging --

what information does the ecu transmit when datalogging? i know that it doesnt output a wideband o2 signal and it is difficult/impossible to tune using a narrowband signal. so other than rpm, what else does datalogging the ecu tell us? i am just trying to figure out if it is worth the trouble. thanks.

 

sensor readings and throttle positions....blah blah blah. Look on the uberdata forum, it has a list.

 

call me stupid but your stock map sensor will read 10lbs and the uberdata will be fine using that

or if i wire in a gm 3 bar i will be fine with that with the uberdata

Yeah, theres a place where you specify what map sensor you have.

 

I cant say it enough. please refer all your questions to http://www.ecimulti.org/uberdata. this thread should just die.

and yes, you can run 10psi on a stock map sensor.

 

yes i have the software just making sure that the map sensor part was functional thank you bye bye

 

there is something else on that site. its called an uberdata support forum. i figured most people would notice that since i keep sending people to the site for that purpose.
