ordered my jwt ecu
First off, thanks to Neal for all his help and info 
I searched around on www.car-parts.com and found a nice 96 SE manual ECU for $110 shipped, so I called JWT and got my order started. $595, ouch, but I gotsta have it. The junkyard is going to ship the ECU straight to JWT for me, and they said it should take about four weeks, then they will ship it back to me.
Hopefully my MEVI will come in around the time I receive my ECU
I told JWT that I wanted the 7200 rpm revlimiter over the standard 7000 cut.
Can't wait, two more months and my car will be flyin.

What did they tell you was the HP gain for your car? Just curious, since a friend of mine is a programmer for JWT and when I talked to him about doing the same thing for my '97 SE, he told me it would only get me about 10 HP. Didn't see like a cost effective thing for only 10 HP, but if you need ever little bit....... ;-) I'm just sayin'.

Peak gains aren't the goal of the ECU. If the JWT ECU did absolutely nothing besides raise the rev limiter, cars with MEVI and a raised rev limiter would still be the fastest N/A cars on this board. Take a look at the dyno graph of a car with MEVI and check out the average HP over the "racing RPM range" call it 4500-6500 on a car with a stock rev limiter. Then check out the "racing range" on a car with a 7000rpm limiter. Say from 5000-7000, the car is making much more average power over the range of 5000-7000rpm than it does over 4500-6500. That's where the beauty of the raised rev limiter + MEVI comes in. Any gains provided by the ECU (and trust me they are there, you can feel them bigtime from about 3000-5000rpms) is just icing on the cake.
BTW don't hold your breath for JWT to have your ECU to you in 4 weeks... they told me 2-3 weeks and it ended up being like 6 and a half. When you get it though it will all be worth it.

And with the ECU, you really can feel the difference in power from 3000-5000rpms. When you get the MEVI (with stock ECU), the strong lower end power disappears a bit. I really missed that turbo-like surge of torque from 3000-4800rpms the stock intake manifold gave me. Then I got the JWT ecu and my car feels WORLDS better from 3000-5000rpms. This is very nice because I spend most of my time driving in the 2000-4000rpm range. As for topend gains, I'm sure they're there (Requim6 noted them in his JWT/MEVI dyno), but the biggest difference is from 3000-5000rpms. The ECU should have been one of my first mods (even before the MEVI) because it really is that noticable. The extended rev-limiter, while I rarely use it, makes full use of the capabilities of the MEVI. The ECU is a must have.
As for turn-around, from the day I shipped it to JWT to the day it got back to me was ~5 weeks.

You got the 7000rpm limiter too? Ben at JWT really steered me away from it saying the valve springs can't take the revs after 7000rpms and that valve "could" be an issue. Apparantly they've floated valves on the VQs anywhere from 7100-7300rpms. BUT look at Neal, he's doing completely fine with the 7200rpm limiter.
Oh, and you'll be flyin'. It feels like a completely different animal. Punch it from a roll in 2nd at 4500rpm (~46mph) and note how hard the revs climb to 7000rpms and then comes 3rd. It's wicked.

JWT has had mine for a week now, but I am not holding my breath about getting it back in a month.
I also have to give thanks to Neal with his help on the ECU situation, he is the kinda guy that sums up what this fourm is all about.
Ben at JWT did not say much when I asked for the 7200 rev limiter. My VIM can't wait for it's new friend to arrive.

OK. Yeah, I'm not really too worried on JWT comming thru with their four week claim, because due to other circumstances I cannot operate a motor vehicle for another seven weeks 
Yes, 10 hp for $600 (plus I had to buy a 96 ecu - $110 more) seems like a lot, but as Smithdogg said, the main reason I got it was for the upped revlimiter.
Dave - The JWT salesman told me the stock program comes with a 7000rpm cut, and I mentioned that I would like a 7200 cut instead. He then told me the possible problems I might have with revving that high and asked me if I was aware of what he just told me...basically a disclamer for JWT.

BTW I think JWT is saying what they're saying not because they are trying to LEGALLY be unbound if you float the hell out of your valves at 8000rpm and ruin your motor, they just want people to not run around on internet forums saying "JWT'S ECU BLEW MY MOTOR". So if they make it very clear there is the possibility of damage over and above the "normal" 7000rpm limiter people won't go blaming JWT for it. Legally JWT would NOT be liable anyways, whether you float your valves and blow your motor with their 7000rpm limit or if you went with an 11,000rpm limit. They just don't want you badmouthing them and hurting their business (like that doesn't happen anyways
