I've got a B14 ECU here which looks like your P11. That was about 1996 I believe

Im pretty sure the 1998, 1999 B14 ECU is just like the 1999 P11 ECU because all those cars have teh extra emissions crap and MAP sensors while the 97 and below dont have that stuff. Are you sure it was a 96 and not a newer 98?

And the reason I say that, this is from JWT

I'd have to run the part number again

Maybe it was later than what was posted on the forum I bought it from?

Hey Matt today I did a little testing:

I hooked up the 97 B14 200SX SE-R M/T SR20DE 23710-1M870 ECU, but it would not work (connect to consult) with the B14 SR20DE 200SX 1996 OBDII ADR but it worked with the B14 SR20DE 200SX ADR and (connect to consult).

I then hooked up my 99 P11 G20t M/T SR20DE 23710-7J100 ECU and it worked fine with the B14 SR20DE 200SX 1996 OBDII ADR and (connected to consult) I was even able to erase a check engine code.

I have also attached a ~1 minute idling log and the .BIN of my 99 P11 G20t M/T ECU SR20DE using the consult download feature using the B14 SR20DE 200SX 1996 OBDII .ADR

Thanks. do you have the B14 1997 BIN file there at all?

the 1996 model has a different consult initialisation string only used on the later model ECUs (same to Z32 1996 OBD version). going to have to rename that address entry to be more specific.

so the 1999 P11 is similar to the B14 ECU I have here. If I can get that one working here with the OBD-II board then the P11 has a shot at also working.

Got the new USB base image programmer now working on Type 1-4 boards as of last night. Still working on Type 5 and OBD-II board programming and should be able to test those next

No problem, im actually in on that group buy thats going on over http://www.sr20-forum.com/group-buys/33 ... -a-15.html, im getting 4 boards (I convinced my 3 of my friends to buy a Nistune ECU and im also buy another one myself).

I will download the 97 B14 200SX SE-R M/T SR20DE 23710-1M870 ECU .BIN tommorrow and attach it here like I did the other. Im hoping you can do the 99 P11 ECU .

Matt,

Here are the following

97 B14 200SX SE-R MT 23710-1M871 ECU (.BIN)

97 B14 200SX SE-R MT 23710-1M871 ECU (LOG 1 min.)

I'd also like to add that its not showing the DTC code description when there is a check engine light but it will reset teh light. Sorry dont have a screen shot of that though.

And these 2 screen shots showing the ECU part number for the (97) and a partial part number for the (99).

Hey Matt what ECU can you put a Type 4 board in cause I already bought the board on that group buy and I just wanna know what ECU I need to send to them so it can be installed, thanks.

Charlie

Anyword on this yet Matt?

1M870/1M871 are fine to use

The P11 not showing the part # is the same as the B14 OBD-II here also not showing the part number

From the Nissan list this has ????? since no part number displays, I see the same as what you indicate for this ECU. The part number is not available and comes up as invalid characters. Not sure why

B14 SR20DE 200SX ?? USDM ????? N A U OBD2 " JA18-B89 B49"

The only thing about the 97 B14 ECU installed in my P11 is it had a sorta funky idle, like a shaky idle to it compared to say the 95 P10 G20 ECU I also tried on it, not sure why though that was.

And my friends B13 Sentra SE-R 23710-94Y00 ECU would not work with any of the B13 address files, everything came up jibberish not making any sense when I looked at the fuel maps etc etc.

Email / attached that BIN and see how we go with that

I'm getting there with the programmer (Type 5 programs up now but not running in K11 ECU just yet) and hoping to sort that this week and then Type 4 OBD-II board is up for programming next

Ok Matt im not sure if it makes a difference cause im not sure how downloading the .bins using an incorrect address file effects this but I used the 94 P10 .Adr cause it was teh only address file that made the ecu maps make any kinda sense, if you need me to use the "correct" adddress file for a 93 B13 I can do so to but it looked all jibberish (messed up).

address file doesnt affect downloading unless its a 64KB file and you use a 32KB address file then you only get half the download

B13 will do 32KB for example but B14 will do 64KB

So is that .bin I attached good enough for you to look at or do I need download the .bin using the 93 B13 address?
