First, apologize for not posting Saturday as I had promised..I logged on Saturday PM after the demon tweak only to find my home PC with a crashed drive...because I had been in the office all Saturday morning I left my laptop here so I was 'incommunicado' all weekend.

Anyway, here's the short scoop. First, it's a 15-20 minute job at most so I got charged half-hour shop rate, 37 bucks. Second it's easy as heck..just plug the Consult II up, page down the menus until u get to ignition timing adjust and just stroke some keys.

Yes, the 'stock' timing is 15 degrees BTDC. My tech was actually curious as heck to see this happening as no one in Beaverton Nissan had done this before (to his knowledge) so he hooked up a timing light so we (I was in the shop with him) could see the timing change as we stoked the keys..yes, you can see the timing change!

And to that, we only increased three degrees because on the 4th degree the timing became somewhat irregular...as if the computer was attempting to go to 4 degrees but some other parameter in the ECU was them pulling it back so we left it at 3 degrees of added advance.

No pulls to redline yet after this but the car definitely feels stronger in the mid-range...more fluidly torquey, if u will. It's specially noticeable between 2k and 3.5k rpms -right in the 'around- town driving' sweet spot. No pinging, no detonation, everything else is fine. Thanks again, MiniRX7

 

time to schedule appointment with dealer

what wories me though is actually talking to the service department about this and getting a bunch of blank stares and being laughed out of there

 

oh... and thanks for the update

 

really supposed to do that so it will help if you have a friendly tech as I do..he's also a car nut too, he has a Sentra SER with a Japanese engine, headers, cams and other stuff making about 185 hp so...he's cool and knows about performance mods.

This is where giving your service mgr tips & stuff pays off in the long run...

 

A part-time mechanic who was going to tech-school for OB-II onboard computers, claimed 300hp on the school's 3.5L Altima. He said they did this through tweaking the settings in the computer alone.

 

Timing Advance

 

Isn't the knock sensor supposed to advance the timing as much as possible before knocking based on the grade of gas in the car so that you are always operating at maximum timing advance?

 

curve if detonation is sensed. Put another way, the knock sensors will retard from settings of the preset advance curve..by altering the static timing you have advanced the whole curve...if u get no knocking, you're still advanced by x degrees....

 

I wonder if the JET chip increases hp by advancing the timing to the maximum allowed by the ECU under all conditions when no knock is detected. Has anyone here used JET?

Well - I doubt there will be a prob requesting it be set at least to +2 since this would still be within spec according to the FSM.

 

I.C., thanks, now if I can only find a good Nissan tech in Florida

 

Galo can you give us an update. how is car behaving? and problems? did you have it dyno-ed?

 

I advanced mine over a week ago, driven at least 800 miles. No problems so far. I could just be me but like mentioned above it does seem to pull harder all through the powerband. That is my .02
