Here's the application guide on their site:

They don't have a dyno of the VQ on there, but they do have dynos of many other vehicles. I know manufacturer's dynos are always suspect, but its better than nothing. I wonder how these compare with Powerchip (Australian also) and the JWT, G-Force and JET Performance.

EDIT: I just realized it is a piggyback system, not a full reprogram like the others are. Kinda like the Apexi S-AFC and other systems. Sorry guys.

 

powerchip in australia has a chip for 95-99 maximas.. i been trying to talk to them about the 98-99 maximas specifically..

 

Yeah I know, I put it in my original post hehe. What have they said about 98-99. Not like I care since I have a 96 but I'm just wondering

 

well, since there is not chip here for a 98-99 i want to make sure they have the correct ecu to modify aka chip
cause when installed my rev/speed meter i had to use a different ecu diagram than what apexi had listed for the max..

 

ooo. please can you get them to make one for $50? jk Let us know what you find out. I'm so sick of everything being for 95-97. I mean, we all know 99 is a toss-up with CA/fed emmissions, but c'mon...98 needs love!

 

I take it you've received the Maxima 'datasheet' from them.

The engine pictured isn't exactly confidence inspiring, nor the lack of 'data'.

 

yep..


i am trying to get a real person to e-mail back and forth

 

agreed!

 

I really wish there was a chip available for '99s, but I would be worried about using an Australian chip. We have more emissions if nothing else, and 99s are closer to a 5th gen ECU than a 95 ECU.

A 97-99 JWT ECU would be great
-hype

 

haha yeah...I'll go show them some leg and see if they come around to our side!

 

Does this powerchip do basically the same thing as a JWT ECU? If not, how are they different?

 

is this the same as the "uniChip" or "The Program" that is located over at Sears Point CA? if it is id stay away from them. THere the ones that blew my friend's motor. Supercharged 10psi and they unplugged the vaccum line to the FMU to get a "base" dyno.

 

As much as I'd like to promote a local company, PC's claims reek of BS. Anyone seriously considering these should search some Australian performance forums before you send your cash.

 

That is as easy is repositioning 5 wires and adding 1-2 resistors so one can use a 95-96 ECU.

 

That may be the case for 97-98, but I doubt it applies to the 99s. I know 99s have the NVIS as well as an electrical rather than a mechanical EVAP. Those are the only things I can name off the top of my head, but I doubt swapping a 95/96 ECU would work like it does on a 97.

Unichip used to be called the PROgram. I remember someone had it on their SC'ed Maxima a long time ago (I forget who...Steve in Chicago perhaps?).

On a side note, Lyt97SE went to one of their dealers to dyno tune & custom program his ECU & all he ended up with was a blown motor (not from the chip itself; a tech accidentally leaned out his car on the dyno & BOOM!)


edit: oops, I just noticed turbo95max posted the same info earlier in the thread.

 

I want the right ECU in my car, though.

 

Just got off the phone with Brendt @ Powerchipgroup/EDS. Their marketing group got a little ambitious with that datasheet.

They haven't cracked codes later than Feb 95 ECU's (meaning 3rd gens?) They are workin on the 4th gens and it will be a piggyback unit as mentioned above. He said 1-2 months

 

What a load of crap. Don't hold your breath.

So they've admitted to fabricating and distributing a datasheet for an application that doesn't exist? You should ring them back and ask how they came up with the exact 4th Gen power/torque gain figures they advertise.

Blowing an engine while Unichip tuning is nothing more than tuner stupidity, imagine what that idiot would do with a Motec.

 

the tech didnt accidently lean it out. It was his own fault due to whatever reason that he disconnected the vaccum line to the FMU. Not sure if the other person was Steve in CHicago but someone with a supercharged Max got it and didnt get much if any gains so he returned it and got his money back. if this is the same thing..i would NOT recommend it.

 

too bad JWT doesn't have a tech on this site haha.

 

ECUs from before 3/95 are OBD I units, so basically they've done the same thing as everyone else and haven't managed to crack OBD II.
