p10 ecu into p11?

I t can be done?
do the ecus have the same pins?
thanks

I don't believe it'll work or else it would have already been done

Hi

thanks for your reply

but maybe not!
I have read in sr20forum, some guys that have done ,but in a 97 200sx
they have change sucsecfully the stock ecu for the g-20 93-94 ecu (7500 rpm cut),so I was thinking why not ? but Im only gueesing.

I think there are a few pins that are not compatible with the P11. First of all P10s have EGR and therefore BPT valves.. 2 pins P11 ecus don't have. High port engines alse had AIV. I'm not really sure but I think there differences too with the charcoal activated canister too.

Maybe by doing a lil' rewire it can be done, but you must also take in consideration that the fuel maps of the P10 are designes for a 9.5:1 engine not a 10.0:1 engine like ours.

Que pasa machucao?

Ummm...It was in another post...Yes it works...thats why I am looking for a 95-97 SR20 manual ECU. Luke (G22DET) has done it already. He is using a 95-97 ECU tuned by JWT for his SR20DET. That is my plans also...Its still not clear yet if there is to be some rewiring or not...but its only a few wires and is easy..thats what I hear

You can use the earlier ECU's but you will have to rewire a few wires on your 99 harness Tony. You will also be stuck with the check engine light on.

On the 2000+ wiring harness you will have to rewire EVERY connection to the ECU.





Also the mappings are irrelevant. The reason people want to switch to an earlier style ECU is because JWT can reprogram them, unlike the P11 ECU's.

uhhh...was the remapping thing for me? yeah I need that ECU if I am to do the Turbo and run good...anyways thanks..

Nope sorry, I guess I should've quoted...

The rewiring info was for you. The point about the mappings was for 1FastP11. He said you wouldnt want to use a P10 ECU, but I was stating that people arent looking to switch to a stock P10 ECU. They want the older ECU because it can be modified, unlike the P11 one.

:o I totally forgot about EGR -BPT-AIV ,and 9.5 cr:D

Igual te las di jajajajajajaja:devil: :finger:
por ahora!

ok I am still kinda new to these acronyms.

EGR = Exhaust Gas Recirculation?

AIV = Accelerated Inverse Voltage????? got that from a search..hehe

BPT = I have no clue..but seen this before...

Here's a close-up of the area beneath the BPT valve (which is shown at the top-left [green arrow], pushed out of the way). The rubber tube (red arrow) between the BPT and the metal tube (yellow arrow) has to be removed in order to clear the blockage. The meandering path of the BPT tube can be seen (orange arrows).

Maybe there's some things I should mention.... jprimera and I are from Chile, we get japan made P11s with roller engines, 10.0:1 CR, no EGR, one O2 sensor, among other things. Our Primeras are way different than the G20s. AFAIK It wouldn't be optimal to run ECU program designed for 9.5:1 on a 10.0:1 engine, since under extreme condition (summer by example) you could detonate (more agressive maps on the 9.5:1 ECU due to lower compresion). On american's P11 could/can be done. To the rest of the P11 south of the border...you can't! (I think there's a fair amount of people from central and south america on this forum) We've been getting this engine since the year '97 only on the P11 platform. I think central and south america is the target for this particular combo (P11 with this jewell engine, half the emission crappola to mess with, OBD-1 BTW) To the Norht amercian P11 owners I think it should work no problem.

Juan Pablo, cachai como el jote culiao se quiere sublevar?

Si

Este weon siempre es asi

i have to agree with you claudio ,the problem is many people do not know that ours engines are diferent in many ways .emisions for example.

I understand what you're saying. My 2000 G20 is different too and the 2000+ ECU's cannot be reprogrammed.

The compression ratio has nothing to do with it. When I turbo my car I will lower the compression from 9.5:1 to 8.3:1.


What I'm saying here is that if you use and earlier model wiring harness and ECU you can have that ECU reprogrammed to whatever you want. The newer ECU's dont have that luxury. Again the compression ratio and other things have nothing to do with it. You are not swapping to an early P10 ECU to keep the stock program. The point of swapping is to have JWT reprogram the ECU to your specifics. You cant do this with the late model ECUs.


Know do you understand? :D

American 200+ P11 ecu..sure it can't

Really? So if I go 13.0:1 I can use the stock program with 9.5:1 maps? cool!

Nope, the point was saving US$400 and see 7.5K rev limiter. Ain't that right jprimera?

Understand what?

Claudio

Well it looks like you dont want to read the info I posted. Instead you choose to repeat your blindsided remarks. This is not what this forum is about. If you dont have respect than please dont post here.


IF you READ what I posted you CAN use an earlier ECU on your car. You CAN have it reprogrammed to your engine specifics, no matter what your compression ratio is.


I never said for you to use a stock P10 ECU on your P11. I said you can use one of those but have it reprogrammed to your specific needs.



Please dont misquote me. ...and leave your know it all attitude somewhere else.

Hi
I believe that you lost the point b-boogie which I ask was if it were pocible to place the Ecu of p10 in p11 (without reprogrammmed) I believe that 1fast primera leave everything clear(is not pocible)), and nobody has needed the respect to you, 1fast primera express his point,and is right.And if you read the first post made for 1 fast primera ,he clarified everythig.

greetings

Happy X MAS

OK, I didnt understand that in your intial post you wanted to keep a stock P10 ECU program. In that case no.


But I mentioned you can do it if you reprogram the ECU no matter what your compression ratio is. Thats all I was saying until he started taking me out of line.



Anyhow... happy holidays to you too :D

Shure, but you also said that de comprecion has nothing to do with it.(when I was refer to if were pocible to place the Ecu of p10 in a p11),and is here when you lost the point, because you said that the comprecion has nothing to do with it,and has much to do, 1 fast primera leave everything perfectly clear without isult you. He is a exelente person.

Now I think everythig is clear:)

I took you outtaline?

Whatever dude! I answered the question regarding the "once again and I hope this time your attitude can manage it" south american P11. That was the aim of the post on the first place. I'm leaving the subject now.

Peace and merry x-mas

That is exactly what I said. The compression ratio does not matter BECAUSE you can reprogram the earlier ECU.

If you keep the ECU in stock form yes its not a good idea.


1FastP11, yes you took me out of line by mis-quoting me, and then mocking me as if I was completely wrong.


I understand now that you were speaking of stock ECU's while I was speaking of a reprogrammed one. What I meant before (and still do) is that you can take an early model ECU and harness and reprogram the ECU to your needs.


I have a 2000 P11 w/ 9.5:1 CR and will be using a BB DET harness and ECU reprogrammed to fit my needs because I will lower the compression to 8.3:1.


Thats all I was stating from the very beginning. :rolleyes:

this was the principal idea ,1fastp11 and me were refer.

yes ,we where talking about this,

ok .

no body mocking you .
You whrere speaking another thing.
