that's "ecu" not "ecue", sorry it's late....anyway

anyone running a MEVI + ECU w/ a raised rev limiter in a 99? I hear there's something messed up/different with the 99 ECU's. I'm getting ready to purchase a MEVI but I won't want it unless there's a solution to this, meaning I want the full potential of the MEVI or no MEVI at all. Can JWT still send a modified '96 ecu that will work for my 99? What about the greddy emanage? Sorry guys I'm really lost, I've been searching a lot and I can't seem to find the answer. Maybe I overlooked something? thanks

JWT used to have a '99 ECU w/ raised fuel cut, not sure if they still do. Not on their site, give them a call.

 

If you're really lost, do some more reading/researchjing.

Get a hold of Zack342 for more info re: 99JWT.

 

e-Manage Ultimate ...... The answers are out there.

thanks guys, will do more research

 

beautiful thread, thanks for the direction guys. sticky this maybe?

Doesn't qualify to be a sticky IMO. Just one of the many semi-informative threads we have in this forum.


BTW, I still contend that those numbers are anomalous and if you're expecting those types of numbers with the mods he had, be prepared to be disappointed. History says that 201 WHP is not possible without an aftermarket ECU or piggyback.

 

Don't waste your time with the JWT ECU for a 99.... FWIW, I did extensive research on this. Do yourself a favor and search and read through ALL of Zach's threads pertaining the JWT ecu and you'll see that he had some problems. (cold start issues, warm start issues, CEL's...) He sold it to a fellow org member. The new owner had the same problems (and new ones) with the JWT ecu and tried to sell it several months later. When I drilled the seller with questions about the problems, all I got were vague answers and excuses. I PM'd Zach with questions too, but he never responded. IMO, the JWT ecu is not as good as some people make it out to be.

I opted to go with the Greddy EU and couldn't be happier. No cels, no cold or warm start issues......and I don't have a cookie cutter tune.


Cliffs: EU>JWT

 

Edited....

lol

JWT is a decent cookie cutter for people looking for the standard 10-15whp gain on a 95-98, but for the trouble of putting it in a 99 then EMU makes more sense.

 

I have the jwt in my 99. It works great. I have a cel but its for egr stuff and automatic trans error, even though its for a manual like my car. The car runs fine. I have no cold or warm issues. It cranks up fine and I even have remote start on it.

 

I actually wasn't planning on going with the JWT ECU. I read the problems he was having. I'm not expecting 200whp dynos just yet. I'd like to hit that number one day. I'm still finding other info he had posted, TONS of stuff! I bought the MEVI from another orger here, I still need to pick up a couple more things for it.

I'm not very mechanically inclined which is why I want to ask you about the Greddy EU. first off, can you get the raised rev limiter? can you tune it yourself? This whole emanage thing is new to me. Is it an actual ECU? or does the "piggyback" term mean it's an attachment to the current ECU? I see there's a manual for the install but it says:

"*All installation and tuning should only be made by a trained technician with proper air/fuel monitoring tools. (Some or all functions may not be compatible with some applications.) "

I then looked over the .pdf file SCO had provided and it was...well...overwhelming. lol

 

It is an "all-encompassing" piggy-back. Provides you with the ability for you to tune your ignition timing, A/F Ratios (with a wideband-o2 sensor), datalog things.

It does NOT replace your current ECU.

 

awesome, got it! now what about extending the rev limiter? I'm obsessed with the extended revs lol....and what about self tuning? ...

 

Rev limit can be extended, but supposedly when you walk over the exact RPM of the rev limit then you feel a slight loss of power and then keep going (ECU shutting it down and e-Manage keeping it up ... conflicts). You can tune whatever you need ... do some research man. No one is going to spoon feed you EVERYTHING.

 

I'm aware that no one is going to spoon feed me everything, I've done a lot of research already. Just a few questions is all I have.

thanks for the input

From what I've read, the rev limit can be seamless w/EU if done correctly.

 

Theoretically, it's not going to be 100%.. on the datalogger you can see a SMALL rich spike (we're talking a few milliseconds here). However, I can tell you that mine is smooth enough that I can't feel the transition in the car. There's no blip or stumble, the car just goes right through as if it was factory programming. (Oh and BTW this is all with NO MAF in the car either, - or before when I had a MAF, same deal, smooth).

Now I'm interested in knowing if the factory ignition continues past 8000...
