jim wolf ecu
The intake wont do anything for you but give a nice sound, so for right now, I'd leave that alone, if you're going for performance. If you just like the sound, then go for it. The JWT ecu is a great addition, but to take advantage of the changes it offers, you need more mods than what you have mentioned. A y-pipe would be a good start. I would hold off on the JWT for now. Look into an 00VI, y-pipe, maybe headers, then maybe consider the JWT. And if you want to get and take advantage of the extended rev limit, then you may want to think about upgrading the valve springs so you don't get valve float. Cams would make a great addition too, but not mandatory
I did a comparison at the track with and without the ecu a while back. My best without the ECU was a 15.4@88 and when I put the ecu in and ran again I ran 14.9@92. So yeah its worth it.
NO ITS NOT.
I see emanage ultimate units with the harnes selling for $300-$400. Why would you even waste money with Jim Wolf? Also his ECU seem to have trouble with a few of the boosted people. Their cars actually run better with bigger injectors etc. STOCK ecu. as opposed to jim wolfs upgraded injectors program

For our cars even true CAI dont do too much. I have a Place Racing CAI, and haven't noticed too much difference aside from the sound. Our stock intakes are quite efficient. On some cars CAI make a big difference, like LS series engines, but that is b/c their stock intakes are quite restrictive from the factory. This is not the case with our cars. As you go up in HP, then it may be beneficial, but with just that, or even that and a few bolt-on, you will get 1-5hp at most in a 4th gen.
I wasnt talking about huge gains. But I def. have gained 5-7 hp from it. Grant it, my stock intake was pretty dirty as well as the tb. But I agree, the stock Max intakes are above average.

Just for the record there has never, ever been a TRUE CAI for our cars, you have to fab up your own and in the end it will end up looking like the stock setup if you know where the coldest air on the car is.
Back on topic, JWT ECU will serve you right after some bolt ons if you don't want to mess with EU.

i think it all depends on what mods you have planed for the future maybe you just want all motor or you want just a little more kick in the highway ...just think on what do you want in the future so you wont have to spend twice
Thats why I said discontinued, but yes back in the day Place Racing did make a true CAI, and there are some still around, including mine.

I ran with a JWT ECU on my SCed setup and it did ok. Granted you are correct, the JWT FI tunes are really conservative and dont make the most power. They are however safe and realiable.

Honestly i dont think u need to upgrade or mod ECU, unless u doin some REAL modification and pushin over 20HP extra. If all u gonna do is exhaust and a CAI, dont waste money on ECU.
Our ECU are already self-adjusting and will give u best MPG/power as long as u reset it. thats what they there for
If u gonna do MEVI or 00vi then yea, either tune or ECU upgrade def

IDK, I loved having a modded ECU. I had the G Force ECU and then went to a JWT ecu and although the are $$ it was a great mod.
Funny how the ones stating they arent worth it havent experienced one.
Even if you dont have a VI, they do help the low end by altering the timing and AFRs, with a VI the extended rev limiter is awesome and the ability to make power all the way to it is great.
To me, exhaust and a CAI are a perfect base for a modded ECU.

I will re-edit my statement, There has never been a true CAI made for our cars, unless you're referring to the stock air setup, it gets the most and the coldest air to our VQs.
PS. the only reason why I have a SRI are very simple reasons..... Awesome sound and ease of maintenance.
/Intake discussion or at least my participation in it.

One of the, if not THE best mod at the time of my modding.
Ever hear the saying gotta pay to play?
Thats the problem now days on the org, everyone wants something for next to nothing.
The removed rev limiter would really only benifit those with a VI, but the modded ecu gives gains all around making it worth while.

Ah yes, 3ft of tubing just to suck up the air off of the road... which is being baked by the sun, better than stock setup for sure.

I also personally dont agree about a CAI not giving some gains. A true CAI will pull in cooler, denser air while rolling thats for sure. Even at a sitting, the air its drawing in is still cooler then that of under the hood. With a round cone type filter, its able to draw in more air due to the increased amount of surface area vs the little induction opening of the stock air box. This has always been a debate and many have offered their opinions.
I also dont see why your refering to it as only sucking up hot sun baked air off the road. Its not like its acting like a vacum cleaner sitting directly above the grounds surface sucking in air.
Ive always ran a CAI, cant say I felt any true gains except with the SCer. However I dont really felt it hurt my performance either.

A quantitative experiment was done on a 5th gen. IAT's taken with both set-ups. You may have seen it.

well all i know about intake and stuff is u want the fastest and smoothest way to your intake maifold for one a stop intake on most cars are that ruber that is all bumpy so i know that messes with the flow of air the owner of skunk2 told me that so i dunno i know whe i had my mazdaspeed3 i but a intake on that and i felt it big time
JWT ECU is definitely a noticeable mod on an NA car, especially one with a VI where the extended rev limiter gives even further gains. In terms of gains the only bigger gains to be had are 00vi and Ypipe/headers.
The only problems with JWT ECUs have been with some of their forced induction tunes which are pretty sketchy, their NA ECUs are great.

pay to play. yea yea i kno i kno lol.
On topic question....
I was on the Jim Wolf website. DO u have to buy an ECU that specific matches the car? For instance, I wd have to buy a ECU for 97 MT.
And is it jus plug in play, meaning i remove/unplug old ECU and jus plug in/install the new one?
Last question, do i need to tune after installin new ECU?

A quick call to Jim Wolf industries answered all my questions

On topic question....
I was on the Jim Wolf website. DO u have to buy an ECU that specific matches the car? For instance, I wd have to buy a ECU for 97 MT. nope. have to buy a used 96 ECU and they will tune it for $595.
And is it jus plug in play, meaning i remove/unplug old ECU and jus plug in/install the new one? Yup.
Last question, do i need to tune after installin new ECU? No tune necessary after install. Jus need to specify all mods over the phone when buying.
