O.k im planning on advancing my ignition timing tomorro at my buddies shop...
Lemme know if there is something missing from what im suppose to do...

Warm the engine up
using consult 2 choose engine
after it communicates press work support
go to see more choices
press ignition timing
press up (^) twice
press update
press back
on the menu secreen find idle air vol relearn
press it and perform.........

Now my questions are
1... Does the car has to be on and running???
2... Do i have to unhook anything from under the hood before i do this (e.g TPS harness)

 

Looks good, only thing different I did was reset the ecu afterwards. Not sure if it was necessary, but to me it seemed like it would be a good idea for the ecu to re-learn with that type of mod.

How many degrees are you advancing?

 

The vehicle will need to be @ operating temperature. But the procedure can be done while the vehicle is off (in acc pos). But, obviously in order to verify .. you will need the vehicle on.

 

Should be ON, not ACC, no?

I remember the last one I did for an org member with the CONSULT, the ECTS was reading maybe 3 degrees outside of the 'acceptable' parameters. Wouldn't do anything until we let it cool off for like 10 minutes.

 

I was set to ON when I did it, with the engine running.

 

Although I've not done it, I would not reccomend. Our cars are very sensitive and it could cause problems later. I took really good care of mine that I bought brand new in 02. Apart from cosmetics the only thing I did was a short ram intake, however the engine blew at 129k miles.

 

wow, don't you wish that you beat the crap out of it instead of babying it






To the OP, someone told me that adjusting timing on a a33 ecu will only result in the ECU correcting those adjustments after a few days and you will ba back to stock timing. Is this accurate?

I have also heard people say that its the a33b ecu that doee it not the a33.

 

IDK, 1sexyleo has it on her auto never heard of it reseting itself

 

2 degrees.. running with 17* timing...

did you have to unhook anything under the hood??? or did u just hook up the consult, did the timing and all is well?

 

if u dont mind me asking... what are acceptable parameters for out cars??? 15* correct???

 

I've had my timing advanced for over 5 months now.

 

correct

 

o.k just making sure... so is there anything needed to be unhooked from under the hood, thought i read that somewhere???

 

Well, maybe you should have modded it then. I've had the timing advance for over 4 years with no issues. I have a lot of mods and have never been accused of babying the car. In fact, I hammer it all the time. Mine has over 140,000 and 've never had an issue with the engine. Nearly all my power mods have been on for well over 3 years.

I think your case is pretty unique and doesn't represent all Maximas.

 

You don't even need to pop the hood.

That's stock base timing, yes. I was referring to coolant temp, don't remember the specs now.

Indeed, I did her car and John's (vqmonster) a while back, and I've never seen one 'reset' itself.

Exception, not the rule.

Just advancing the base timing won't cause the engine to explode, the VQ is hardly 'sensitive'.

 

well i have a 140K motor still running and mods in my sig... u might just be the one bad luck out the bunch, not because ur motor blew at 129K means that all VQ motors are sensitive, ask Sho off, 24K, or myself (my old 4th gen was beatn for about 75K+ miles and its still working beautiful) i understand why u may be a lil conservative, but im 100% the motor can take it, and if not, ill do another motor and do it again..

 

thanks PM (again) you should just change ur name to maximaJesus .. is there something about a VQ you dont know about???

 

done... i think, i did WOT the car on the way home and in 3rd it kinda had a funny feel to it, it was the feel of like when u have a missing plug, IDK if thats the ECU resteting itself like secondtonone said

 

I thought the ECU uses different ignition mapping at WOT, so if that's true, you could rule out the effects of the advance

 

No opening the hood, your description Is correct via 17* timing. Nice noticable up-grade.. Off that note, anyone ever heard of running open loop all the time, and any benefits. If so, PLZ list how too.. or not, THX

 

did you have any problems with oil consumption?....i understand that this is a hit or miss problem with the VQ35DE

 

Ya brain fart ... ON, but not running.

The Cipher flashes a warning window showing the actual ECTS temp w/ a message stating it's not there yet.

 

I had this done to mine a few months back, as it turns out my car actually had the timing retarded to 13* so the bump up to 17* was a bit of a kick. Got a little more tourque, about the same mileage but get some knocking at 1/8-1/4 throttle if I use cheap (Arco) 91 octane gas. Other than this there are no other mods done to my car which is at 105K miles.

 

same here about arco 91, i started using shell 91 and my knocking problem went away.
