Jet computer upgrades

[RipShift]

ok I did a search and didnt come up with and didnt come up with anything. I've heard mixed reports about them and I want to know what some of you guys who may have had 240sx specific experience with them have to say.

Jet ecus are a scam, they do not modify the tune in any way. I have a sohc ka24e JET ecu tune, I have verified it is 100% stock.

It is also well known that JET toyota ecus (more popular than nissan ones by far) are scam as well.

they are placebo ecu.

ok looked at the JWT ecu stuff, theres not much info about them on their website. What exactly do they do? Just adjust the fuel and ignition curves and that type of thing? Are they like what Jet claims where they'll tune them to any performance parts you might have? Whats an average hp/ performance gain from using them?

RipShift, what year car do you have? 89-90, 91-94, 95+?

JWT or Enthalpy...only two I'd ever trust.

In order to tune your 91 ecu you need an sr20 type daughter board.

They are available here, http://plmsdevelopments.com/ , or you could check out what biki has go here http://bikirom.com/

Chipping and tuning your ecu (just like jwt or enthalpy) is relatively easy. Solder in the 40 pin connection for the daughterboard, trigger a jumper, and your ready to go. Lots of great free software available to do it all on your pc.

Jwt or enthalpy ecus are good (mostly turbo versions), but you can accomplish the same thing yourself for less money, and have all the equipment to chip/tune more ecus.

check out forum.ztechz.net for more info. And that link ralphdig gave is a good one as well, its specific to z32 ecus but lots of similarities.
