Uhhh...

hehehe whoa!
higher redlines kick ass!
Throttle response is so much better that I don't know why I didn't notice how slow it was before.
Probably gained a couple hp everywhere, but I'll dyno test later (end of summer?) to confirm.

Damn you. LOL

My custom exhaust was put on today. Only gripe I have is that it bangs around a bit over hard bumps and stuff. Nothing that can't be fixed though.

BTW, can you let me know what you had to do for the custom ECU? (soldering)

Yes the ECU was the best thing I did!!!
Once I put it on and put my foot down I noticed how much of an impact it made. Next thing I try is Headers and see how they are. They were really good on my old car but this one being so much more quicker I cannot wait. Good luck Jacen

Looks like another dyno day. I'll have my house by then, so we'll have a cookout the same weekend. Maybe Ben can come down and see what the Courtesy exhaust did for his car. That is unless he decides to hit another deer.

jason,

where did you get your ecu, a junk yard? Since you live fairly close to me, I was thinking of trying to get mine from the same place.

Yup. Sounds great. The NX should be running by then so I'll get Wendy to take her down too and we'll dyno it. Too bad we couldn't bring the 400k Celica too


Even if I do hit another deer I will have 1-2 other cars to drive down there in, depending on if we give/sell the Celica to someone or not.

I mail ordered mine. Here are two places: I used the first.
------------------------------------------
Call Northern AutoSales. Talk to Brian. 610-837-6606.
Tust tell
him you need an ECU for a 95-97 200SX SE-R.
[from Ray Kawski]

Or

If you still need a ECU, I can get one for $150. Either
email me, or
here's the info for the guy who has it. His name is John
Ward, and his
number is 1-800-624-4856 ext 222. Just press his extension
in when the
lady starts talking. He works at a salvage yard, and he's
the same guy who
hooked me up with one. He can take your CC number and send
it to you. I
know the guy, and he won't rip you off.
[from Eric Waterman]


You'll also need to buy a 96 SE_R EGR solenoid valve and rewire some tubes. I can email you the info when you are ready.

No soldering needed, I just spliced and taped two wires. There was plenty of room if you take your time and undo some of the factory taping.

jason...you got an mil light right? If you install the o2 sensor from 97, will that take away the mil light?

Yes, and yes. But the rear O2 sensor is over $100 and is a 12mm, while the hole is 18mm. It doesn't do anything (read your FSM).

<font face="Verdana, Arial" size="2">how much was the EGR solenoid? </font>
ABout $50 shipped.

Where from? The dealer?

Ok so far, what you need for the 98 ECU is:

1. A core 95-97 200sx SE-R ECU

2. Send it to JWT to be reprogrammed

3. Get a 96 EGR Solenoid

4. Do some minor rewiring

?? Is that right?

Wow, Jordan... I'm surprised you have forgotten the few times it's been posted to the SE-R list. Here, I've saved you the trouble, and did some archive searching myself (I totally dig archive searching!) Here's the instructions:

"Installing 95-97 ECU into 98 loom on 1998 200SX SE-R.

1) At the ECU plug, cut and tape Evap. vent sol. wire at pin 108 and move the rear O2 heater wire from pin 110 to pin 108 at the ECU.

2) Replace EGR sol. valve with one from 95-97 SE-R.

3) At the ECU plug, remove wires from pins 28 & 63 and cross over (i.e. wire 28 to pin 63 and wire 63 to pin 28). These are the air and fuel temp wires.

4) Replace the rear O2 sensor with a 95-97 type. Adapt 18mm hole in CAT. for a 12 mm thread on new sensor. Adapt wiring for new O2 sensor. Remove O2 sensor wires from old 4-wire plug. Remove center wire from new sensor and install it in the 4-wire plug so it matches the white wire on the ECU side of plug. Next take the other 2 wires from the sensor (heater) and install them into the 4-wire plug so that one wire matches with the red/yellow and the other with the brown/yellow. this will leave one blank pin at the black wire."

FYI, JWT at one time was accepting '98 ECU's for a core, but I guess they are in short supply of '95-'97 ECU's (I was the last person they accepted a '98 ECU from.) FWIW, the SE-R listmember who did the rewiring on my car cut, spliced, soldered, and used heat shrink tubing to reenforce the splicing. An EGR solenoid and o2 sensor for any of the '95-'97 SR20's should work, although I haven't gotten off my lazy ass to get those items yet. Luckily, I don't have to smog the car until next summer. You could also widen your search to '94-'96 G20's as well. Without them, it'll be like running without an EGR, and there will be two error codes stored in the ECU (EGR and rear o2 sensor malfunction, although the rear o2's job is only to make sure the cat is working.) You'll also need to unplug EVAP system. I've been told by Mike Kojima that the '98 car with a JWT ECU won't idle well and might not run well with the EVAP system still plugged in. However, there is no error code for the evaporative emissions system, luckily, so you won't get an MIL for that. There are two plugs; one in the engine bay right next to the firewall (small black box... should say EVAP on it)... and one under the rear of the car towards the drivers side (big black box.) There should be two plugs there, a gray one and a green one. FYI, I unplugged the gray one.

Ack. Sounds slightly complicated. But I think if I had the ECU sitting here in front of me I could figure it out. Right now its just hard to picture.

its hard to picture when you have the instructions. However, when you start actually moving tubes around, its not that bad. They just are NOT desinged to be swapped around, so they are not in a convienient place and don't come off very easily.

It IS worth it.
