Adjust the idle screw out a turn or two. If that doesn't work, report back.

Neither of those codes show up when I check a list of trouble codes... what ECU are you running? What fuel pump?

jim wolf reprgrammed 89 240sx ecu

Post by **nametakennow** » Fri Oct 20, 2006 6:24 am

.... Weird, I guess that'd work.

Anyway, the second question: What's your fuel pump situation? Stock or Walbro 255 or what?

dont know bought the car with motor in it im tryin to get it through inspection so im tryin to clear up the mil

I have never heard of anybody using a 240 ecu in a sentra.

Post by **nametakennow** » Fri Oct 20, 2006 12:02 pm

Well you'd best find out what exactly you've got. I find the 240 ECU idea rather fishy as well. I guess after JWT messes with things, the ECU can't tell the difference... maybe... sure it wasn't a 200SX ECU?

If your fuel pump is stock, it may be fried. I'm rather certain that's why I'm having nearly the same problem you describe.

DAMN THIS IS WIERD IM CODEIN FOR AN EGR TEMP SENSOR AND A CRANK SENSOR WTF IS GOIN ON

Post by **nametakennow** » Sun Oct 22, 2006 1:57 pm

I don't think the previous owner was completely clear on what had been done to the car.

Post by **01turbosentra** » Mon Oct 23, 2006 3:27 am

i bought it from my moms fiancean he dont have a clue whats done to it

Post by **nametakennow** » Mon Oct 23, 2006 6:31 am

Someone must have a clue.

It's hard to fix problems when you don't know exactly what you're working with.

Post by **01turbosentra** » Mon Oct 23, 2006 10:06 am

yeah it is. im sure i can get the egr temp sensor code deleted with reprogrammin

Post by **nametakennow** » Mon Oct 23, 2006 12:38 pm

If you do indeed have a 240 ECU, get a B13 SE-R one tuned by JWT instead and look into the requirements for an OBDI conversion. It should be simple with that ECU, and it'd save you a lot of headaches with trouble codes.

Post by **01turbosentra** » Tue Oct 24, 2006 2:59 am

whats wierd is why can i access my current computer trough obd2 still and why would it throw a code for an egr temp sensor i think its a reprogrammed stock ecu

Post by **nametakennow** » Tue Oct 24, 2006 9:18 am

Stock B15 ECUs can't be reprogrammed, no one's figured out how to crack them.

Is there any piggyback management like an SAFCII?

I think you have a stock ECU. In fact, post a pic of your motor... I have another suspicion.

Post by **01turbosentra** » Tue Oct 24, 2006 12:36 pm

its def an an sr2odet trus me on that one its out of a pulsar gtir

Post by **nametakennow** » Tue Oct 24, 2006 4:24 pm

You sure it's not a USDM SR20DE with a GTi-R turbo setup?

Anyway, pull the ECU out and look at the back of it. Check the numbers with a Nissan dealer.

Post by **RED_DET** » Tue Oct 24, 2006 8:13 pm

Just give me the numbers off the ECU and I will tell you what it is out of. If you truely have a GTiR setup, that is the first problem. They are hard to get tuned properly, especially if one isn't using the correct ECU. I would also like to see a pic of the engine bay.

Post by **01turbosentra** » Wed Oct 25, 2006 1:02 pm

ok when at WOT the trottle position say im at 69.4 to 70.0 percent i dont think this is correct shouldnt it be at 100% and at closed trottle its at 00.4%

Post by **nametakennow** » Wed Oct 25, 2006 1:50 pm

Wait, you said you had a Bluebird swap earlier, now we're talking GTi-R... this is definitely confused.

If you're talking about only showing 70% throttle on an SAFC, check your connections to your ECU wiring. If it's not soldered, I'd suggest that method.

Post by **RED_DET** » Wed Oct 25, 2006 7:52 pm

Until you tell me exactly what kind of ECU is running the car, its pointless to try and trouble shoot anything. So what are the numbers on the ECU.

Post by **01turbosentra** » Thu Oct 26, 2006 11:19 am

im confused to its a bluebird swap ok the pcm is jim wolf reprogramed pcm from a 95-96 ser mt 8.5 cr eser6-tmu03

Assuming you're still using the B15 harness, check the wires against this guide: http://jgycustoms.com/b14wiring.htm

By the way, punctuation would be helpful.
