I have a 95 GXE with all the usually bolt ons, I'm looking to get some more power and to rid myself of that darn speed limiter
So my question is which ECU upgrade is the better choice? I've been searching and reading loads of posts but none really give me that information. Seems they both give increase in power but I wonder if the fuel mapping is that different? Some posts seem to say that one is better then the other but then there are so many conflicting posts on here and many people who are inputting thought rather then fact. Any VAULABLE information is appreicated.

 

theres a How-To to turn off the speed limiter

 

Yea I know about the switch, been there done that. Just if you leave it off, or open the circuit too long it causes a CEL, unless there is something new someone has done that I don't know about? I'd rather get the upgrade and do it the right way not to mention the added HP and TQ.

 

Unless you plan on getting a variable intake, then just go with the Gforce, they apparently send you your reprogrammed ECU in a very timely fashion, which can't really be said for the JWT. Also, the Gforce is supposedly more aggressive, so it'll get you a little bit extra power, but use good gas.

 

I was thinking about getting the MEVI but that is sometime away. I think I might go with the Gforce for the time issue and the price, I'll post it up if I get it.

 

What does the re-programed ECU do that is different than he stock-programed(nice words) ECU? I understand it does something different but what?

--It just seems to me(after reading how quick it is shipped back) that it is just one tiny modification that takes someone a few minutes to do--and if all it took was a few minutes why didn't nissan do it in the first place?

 

I think they keep your ECU and leave it to be modified later, and send you one that they already have completed.

correct me if I'm wrong, anyone.

 

Most place work like that where there is a core charge which they refund when you send in your stock ECU.

Reprograming does a lot, it all depends upon your mods cause they can tweek the ECU for them, ie NOS etc. Basically it will increase HP and TQ by advancing timing, fuel mapping changes and up rev limiter(sometimes)/remove speed limiter
