NOW FOR SALE!!!!

My 99 JWT ECU, 7200 RPM limit. Self diagnostic screw never used (still a virgin This ECU gave me extended RPM, extended useable RPMs(powerband) and more power throughout full RPM range. This ECU does give you codes but for me the power increase is more than worth it. (Like a Ypipe) I'm having some problems with the driveability with my car through no fault of this ECU but to fix them I've taken it out, I'd really like to fix the issues and keep it but it might do others more good than me. This is a rare ECU as I think this is one of only 4 right now, maybe 5. The price I'm looking for is around $580 picked up or $600 shipped. If I recall you can't get an ECU like this for much less than $700 from JWT(maybe more).

 

I have one in my 99 and you can definitely feel the difference with jwt ecu.

 

mmmmmm. sounds tasty, but i dunno....arrgghh

 

i want it, and its worth every penny, just dont know if i can bring my self to spend that much cake!

 

your avatar is hot!

 

Ok everyone, as much as I really don't want to sell this ECU I'm putting it up for sale!! I have quite a few things I need to take care of on the car and This ECU could be making someone else happy. So Price is $580 picked up/met or $600 shipped. Price is firm. post up any questions

 

ECU is up for grabs

 

is there anyway to install/tune this so that there will be no codes?

 

I'm not sure, I would probably say there isn't but it may be possible. It's a 96 ECU with JWT POP upgrade/remap then it's configured to work on a 99 by switching some internals.

 

Bump for the weekend.

 

I don't think you mentioned if it's auto or stick and I don't think you mentioned if it's CA or Fed. What codes do you get with it? Was this one of the experimental ECUs programmed from a '96 ECU to work in a '99?

 

Its out of a 96 so they are all the same emissions wise. Its a 5spd ecu.

 

Thanks Jon! Right, my car is a cali spec 99, maybe these codes wouldn't appear or not as many on a fed spec 99. I'm not sure...

1. P0443: Evap Emission control system Purge Valve C fault
2. P0705: Trans Range Sensor Circuit malfunction (PRNDL Input)
3. P1400: Manf control aux emission controls
4. P1445: Manf control aux emission conrtols
5. P1220: Manf control fuel air metering

 

Alright guys, I'm in no pucker to sell this ECU. If it doesn't sell I'll just hook it back up since my car feels like a slug without it right now. If I lower the price it won't be by much, and it won't be for a while I think. But after all that, BUMP!!

 

What about the other issues you were having? (Read through your old threads) Ever resolved?

 

need to test it at the track!

 

Well, most of the thread on this ecu was trying to figure out what was keeping the check engine light codes up. Began thinking that maybe theres a discrepency in the wiring between a 96 and 99 as far as the ECU goes with the new EVAP Emission stuff. But to answer that question bluntly, No the ECU CEL was never resolved. My car in itself has an idle and misfire problem right now that has nothing to do with this ECU. I just wanted to revert to my original ecu to make sure of that and to fix the problems.

Oh, Jon. Let me know when you're going to start going to the strip and I'll come along with the ECU(and my max) and we'll have a hayday of it dude! I have fridays saturdays and sundays off now so it's no problem at all

 

What about the warm start issues? Also, the starting issues after getting gas at the gas station? etc etc. There were a few more issues than a few codes.... Did Zach342 ever redyno with the reflashed ECU (for the second time around) and actually show gains? More info please......

 

The warm start issue was not either, I accepted it as what it was. You basically have to give it gas if it sounds like it's going to die out. Sounds like a v8 when you have to choke it when that happens. The ECU is pretty fuel hungry especially on warm starts. Cold starts appearently are not the ECUs fault as I still need to give it gas everytime I start it with the stock ecu.
I'm not sure if there are any dyno'd proof of gains but I'm more than positive that it's a decent amount, feels like a 15HP gain throughout. I'll take it to the drag strip that Jon hits soon and time the differences. If there was a MEVI or SC/TC you would compound the benefit of an ECU like this.

I'll try to find and anchor the other thread to this so I can answer questions better and everyone knows whats goin on too.

 

Ok guys, I said I wouldn't do it but I will anyway. Lowering the price of the ECU to $500 Shipped until tomorrow morning. I'm buying an additional car and the extra cash could help hold it til the loan goes through.

 

can I pop this in my auto and would it work?

 

Umm, I'm not sure. I know that JSutter(Jon) and I popped a stock 99 auto cali ECU into my 5spd 99 cali max and it started the first try but couldn't stay running for longer than a second. and after that it wouldn't even start. So I think it would be the same in reverse.

 

damn..........

 

my buddy told me also, that this wont work, SOB!

 

96blkonblkse Has last dibs on this. If he doesn't purchase then I'm taking it off the market and back in the car. Thanks!

 

Was up man still want to sell ecu for da 99

 

Ummmm this thread you bumped says 2007.
Wow.

 

I have this ECU, dyno numbers were a gain of 5-6hp. And yes JWT still will make them, so it's not rare.

 

JWT is outdated now.
Nistune is where it's at if you're serious.
You can actually tune nistune yourself.

 

Yep, That's the way to go Nistune and a dyno. Nistune is actually cheaper too.

 

Nistune don't work on 99...

 

It can.

 

Is this a discussion thread or an old thread that should be closed? I think the later.
