Ignition advance ?'s
 

I was looking over a friends ignition map on a D16 with "he claims" 110oct leaded fuel. He's running a Holset Hy35 @ 12psi.
Dyno paper he emailed me showed on the 4th pull 243hp, but on his map I'm seeing 27-32' advance? I'm by no means a Engine Tuner I leave it to the Pro's for that. But I went and checeked my map on my H22A and I'm at 23-26' advance at most. Is this alot of advance? Would you rather turn up the psi and be more resourceful with the advance. I asked him whats he going to do when he has to get pump, and he said retune it next week for that. Any idea's why so much advance?

This belongs in engine management.

It's a forced induction motor so it can be in both.

You're ------- retarded. I just called you a retard so I guess this belongs in GD :8

Go back to General Bullshit, since your the best at bull ----.

Re: Ignition advance ?'s
 

where is it advanced that far?? what D16? stock compression? Post up the bin file please

Re: Ignition advance ?'s
 

tell him to turn it up to 20 psi and go for it on pump gas!!!! lol

Its a Y8 running Eagle rods and I believe it's a 10:1 compression Weisco's"or how evaa you spell it". And I already deleted the screen shot picture off my email list. It went from 3500 to 8K from column 1-6 I believe maybe 7, but the ignition dropped off as it reached higher map. But never dropped below 27'. I'm just asking if this seems right or not. Again I'm not a engine tuner so I could be just blown off.... :X

Well I went to the hondata site and looked at a few of their maps that they have posted and they are pretty much the same but going with 50 and scaling down at it get higher into load and rpm.

I guess the numbers and EXTREME RED boxes just threw me off

No two engine/engine setupo's are the same, do the Sweet Spot tune and dont worry about what everyone else is running/doing.

No point in running more timeing than the sweet spot tune, unless you looking for a nice big bang....

Re: Ignition advance ?'s
 

I agree but just the point of seeing 50-30's advance with respect of crank angle just bawgs my dome. Seems like alot of stress on the bearings and rods

Re: Ignition advance ?'s
 

But your asking questions about ingition advance and the tune on the motor. so...

Re: Ignition advance ?'s
 

GOOD OBSERVATION :D
Did you really need to be a play by play persona'

Re: Ignition advance ?'s
 

This is the stock high cam ignition table for a z6, I cant imagine a y8 being too much different. Ignition advances are in the 40's where you are saying, big deal how often do you run 6k+rpm with that much vac. even so big deal. I'm not a professional tuner by any means but those columns are in vac. anyway, that much ignition advance in the boost side of the table would prolly be a different story though.
