Hello everyone,

I have recently built the bottom end of my 2004 350z to handle some boost. I am using uprev software to tune it. While attempting to tune, went into the ignition timing tab and found a chart of numbers that is basically useless to me. Is there any type of conversion chart to change these numbers to degree of crank revolution, or can anyone make any sense of these numbers to me.

I will try post a picture of the chart tomorrow, as I can't open the rom editor while not connected to the ecu and I have the car at the shop still.

Thanks.

 

No direct conversion, but you can read the manual to learn what 'burn time' means.

 

Where do I get the manual. I checked the documents section on their site and didnt see it there. I didn't get it in the box. Is there a pdf of it somewhere?

 

Please do, I've been desperately looking for the OEM ignition timing table .

Thanks,

 

he's just going to post the burn time table that uprev uses, there is no ign timing table in crank degrees

 

My chart doesn't say burn time. its time for max cylinder pressure. So there is no way to convert this, nobody knows where I can get the manual that describes how this works?

 

UpRev Nissan Tuning Guide .

 

 

Thanks for the link amr

 

Burn time == time for max cyl. pressure... again, read the manual. Three times is best.

 

read the manual, and was using the rom edittor and real time tuning all at the same time and worked out really well. now just gotta work out some mechanical kinks and get my boost to 18psi =)
