im sure ive research this before but say for exmaple somebody is doing a 5spd swap in the 5th gen, it is in fact possible to use a 4th gen 5spd ECU in the 5th gen correct??? just gotta get a reprogrammed key???

 

The connectors are different, not plug and play.

 

sounds like something id do hahah



Why would you want a 4th gen ecu in 5th gen tho?

 

The connectors are completely different.

I'm willing to bet the the engine would run, as they are almost identical from a control standpoint, but you loose VIAS control and getting it to run code-free would be almost impossible. Too much emissions related mis-matching between the generations. The EVAP systems are very different.

 

This.

 

4th gen JWT ECU lol

 

That's a danergous ECU. AFR has always been way too lean.

 

oh thats what i assumed the reason was, really a huge waste of time.




5th gen PNP EMU? Yeah, I can do that...

 

i have a wideband on deck

might have to if you will

 

And so did all the other guys that had it. That's how they verified it was lean. Any other way of adding fuel just in case?

At that point, you're probably better off going with a different method being the $$ spent for the JWT + AFC.

 

EMU i guess... i do want n ECU though

 

so he can use a jwt ecu

 

thought the wideband was mine

 

I've thought about doing this too for the same reason. Mainly just for a 7500 rpm rev limit. Sure the emu can do it, but I was trying to avoid that annoying dip we get when extending the revs.

 

I just wish he could of made one for 5th gens already.....

 

I talked to a guy from JWT a couple months ago about how hard it would be to do it and he said like Flava the connectors are different so there would be some tricky wiring to do but he made it sound do able, Nmex stated the 4th gen JWT ecu's run real lean but couldn't you just adjust it with a little a/f corrections via SAFC,VAFC, NEO etc ?

 

But at that point, (JWT + AFC) why not go with a better system, i.e. UTEC/EMU?

 

Yes. But there is a chance you will have that nasty dip when you pass the stock limiter.

 

Ill be a test mule and supply everything needed if someone thinks they can do it, I already have a Neo to tune a/f's, They only thing that kind of sucks is 4th gens don't have NATS so i think if you swapped in the 4th gen ECU you would lose your factory security system. Ill even do a before and after dyno comparison.

 

im willing to give the guy my ECU to experiment... cant see how its soooo difficult... shoot TS use to extend revs on the DEK's... larrio IIRC had one... so we know its not impossible

 

$300-500 EMU
$100 Harness
$200-$300 for tuning
vs about $500 and ill be o.k with the extended revs n no dip, just like essential mentioned

 

Actual tuning that you can make changes , vs a pre set jwt ecu that you cant change?


Apples to Oranges to me



No need for the comparison imo, if you want tuning that works and will have less issues get a emu, pnp harness, wideband, there ya go. If you want to pioneer putting a 4th gen ecu in 5th gen its possible, but look for headaches, issues, obd2 compliance inspection issues, and a pre set tune. All the $$ time and effort to do the swap would be more then pnp emu IMO.


That's the real question what do YOU want?

 

understood.. see i dont really care for all that extra stuff with this car... a ECU + AFC and dyno time would be more than enough... i just want extended revs and tune thats all, dont really care for "maximum tuning capabilities"

 

I really don't see the benefits of using that ecu and a afc over a emu. $$ is not one


Coming from all the crazy ecu stuff i do, this would be top of the list!


But if ya need ecu connectors (4th n 5th gen) i got em.

 

makes me feel better, ive always preffered s modded ECU vs something always hooked up to my ECU.... hence why i had gotten a TS over a UTEC in my 5.5

 

Be like me... TS ECU/AFC/UTEC

 

Ya i see, but it wont be just the ecu? A AFC added in also?



Hahah, Trade all that in for a Haltech//////

 

I really should consider it. Aside from my shaking problems, I think I also might have an effing exhaust leak at the header. The cab smells strong of exhaust only when I am in re-circ mode using the climate controls .

 

yea, i can deal with that.... just for basic tuning, me buying a UTEC is a waste because i wont get in depth with tuning... just as long as the AFR's are good im good all the other stuff i dont care for
ur not gonna do it lol

 

I think 99 was the only one with immobilizer

 

yup....... i wonder if this was part of the reason they never realy messed with the DEK ECU's cause from what i understand they are somewhat similar to the 99's
