Hey, I got a sr20 ecu from my buddy a bit ago. And I have the 1.6 motor. I was just wondering if I put that ecu in if it would make my car better. I didn't think it would run the motor, but I don't know about ecu's. Can someone please tell me if this would help my car. Maybe make it faster?? Thanks.
On 91-94 Sentras you must first buy a ECU for an SE-R of the same year range and type, for instance you must get a 5-speed California SE-R ECU for a 5-speed California Sentra, from a junkyard or from the dealer to send to JWT. If you want the VTC variable cam timing to work, you need to have JWT enable it’s use with there add on control module, which is no big deal. For 95-97 Sentra’s JWT can reprogram your own ECU if you desire. For 98-99 models, a 95-97 ECU is needed and some minor rewiring of the rear O2 sensor and EGR solenoid is needed, again, no big deal. JWT can provide instructions for doing this.
Once again I ask, since nobody ever answered last time, if anyone knows how to tell the difference from a cali car and a fed car, for 98 200sx, hopefully i get an answer this time ^_^

First off why don't you start a thread for this rather than just posting it here. Secondly there is no difference in the 98 models between cali. and federal cars, both of them had close coupled cats and the same emissions systems. There may be other minor differences but they are largely the same. What specifically are you wanting to do?

Hey Wes, when you first got your your JWT ECU, before you went turbo, did you opt for the extra module to make the VTC work? If so, what does it do? Does it make a big difference and, if so, where in the powerband?
I know the VTC is not like a Vtec, but what does it do?

On B14's you use a 1.6 ecu so the VTC program is already there, They simply re-work it, they keep it from retarding at around 6000 rpm's which it does out of the box.
In a B13 I would say it will help a ton. I remember Eric had that setup and loved it.

OK. So maybey I should have gotten, but it was like an extra 200$. Still, what does it do precisly? Does VTC, mean variable timing cam? Is it even more a factor for a person like me who has a B13 GA16DE with the JWT S1 cams? Finaly, do you think Icoudl ask JWT for the add-on module without having to send them my ECU? Whats more, I have a 1993 NX2000 (SR20DE) ECU that was reprogrammed by JWT, does that change something?
Thanks.

Well Wes
I did start a thread about this, if you want to look it up, about a week ago, and nobody answered my question, so I decided that if I posted in a post people were already looking at I might get something like I just did, but I'll go bring my old post back and see if I get any bites!
Its great to see a definitive answer. I'm still dumbfounded though why I have a Cali emmission car even though it was bought here in good old Kansas. That's all right though, I like the environment.
As for the SR20 ECU, I believe it can be reprogrammed by JWT to run the GA16 but it will probably cost as much if not more than just swapping for a preprogrammed.

The point is that B13 cars require you to use an SR20 ECU for JWT to reprogram.

its not where you live to determine the cali or fed model, if you are thinking bout getting a jet chip or something like that.. u might as well just hand your money to me cuz they dont make hp... actually people have said they have lost up to or more than 5hp with those.. ecu being reprogramed by jwt is the only way to gain hp and make your car run sufficiently... and it is pointless to get an ecu reprogrammed unless you have turbo or cams..

Start from the hypothesis that I dont knwo anything about engines and answer the question I asked before: what does the VTC do? And if I didnt opt for that option when I sent to have my ECU repogrammed by JWT, could I just ask for that module right now without having to send them my ECU?
Thanks much!
