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?

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

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....

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....

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
